如何在android中创建自定义对话框？

Question

我想创建一个自定义对话框，如下所示

我尝试过以下的事情。

1. 我创建了AlertDialog.Builder的子类，并使用了自定义标题和自定义内容视图并使用了它，但结果并不像预期的那样。
2. 另一种尝试是继承DialogFragment并在onCreateDialog中自定义对话框，但结果不是预期的。
3. 然后我尝试使用普通的Dialog类。结果并不像预期的那样。

在所有三种情况下，问题是当我忽略标题视图时，对话框的大小不是预期的，当我使用标题视图时，结果是内容视图周围有一个粗边框（实际上看起来很糟糕）。现在我脑子里有两个问题......

1. 我怎样才能做到这一点？由于我已经尝试了很多东西，因此我们将更加赞赏直接的答案。
2. 在Android应用程序中显示错误或警告对话框的最佳方法是什么？

编辑Android Developer Documentation建议我们使用DialogFragments或Dialogs向用户显示错误/警报消息。但有一次他们说......

提示：如果需要自定义对话框，则可以将“活动”显示为对话框，而不是使用“对话框API”。只需创建一个活动，并将其主题设置为清单元素中的Theme.Holo.Dialog。

那是什么意思？使用Activity只是为了显示错误消息是不是太多了？

在这里，我创建了一个简单的Dialog，如：

custom_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="80dp"
    android:background="#3E80B4"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/txt_dia"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:text="Do you realy want to exit ?"
        android:textColor="@android:color/white"
        android:textSize="15dp"
        android:textStyle="bold"/>


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#3E80B4"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="Yes"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />

        <Button
            android:id="@+id/btn_no"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:layout_marginLeft="5dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="No"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />
    </LinearLayout>

</LinearLayout>

你必须extends Dialog和implements OnClickListener

public class CustomDialogClass extends Dialog implements
    android.view.View.OnClickListener {

  public Activity c;
  public Dialog d;
  public Button yes, no;

  public CustomDialogClass(Activity a) {
    super(a);
    // TODO Auto-generated constructor stub
    this.c = a;
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.custom_dialog);
    yes = (Button) findViewById(R.id.btn_yes);
    no = (Button) findViewById(R.id.btn_no);
    yes.setOnClickListener(this);
    no.setOnClickListener(this);

  }

  @Override
  public void onClick(View v) {
    switch (v.getId()) {
    case R.id.btn_yes:
      c.finish();
      break;
    case R.id.btn_no:
      dismiss();
      break;
    default:
      break;
    }
    dismiss();
  }
}

如何拨打电话？

R.id.TXT_Exit:
CustomDialogClass cdd=new CustomDialogClass(Values.this);
cdd.show();  

Updates

很长一段时间后，我的一个朋友让我做了一个透明背景的弯曲形状对话框。所以，我在这里实现了它。

要制作弯曲的形状，您需要创建一个单独的curve_shap.XML，如下所示，

<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <solid android:color="#000000" />

    <stroke
        android:width="2dp"
        android:color="#ffffff" />

    <corners
        android:bottomLeftRadius="20dp"
        android:bottomRightRadius="20dp"
        android:topLeftRadius="20dp"
        android:topRightRadius="20dp" />

</shape>

现在，在主视图布局中添加此curve_shap.XML。在我的情况下，我使用了LinearLayout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="80dp"
        android:background="@drawable/curve_shap"
        android:orientation="vertical" >
...
</LinearLayout>

怎么称呼这个？

CustomDialogClass cdd = new CustomDialogClass(MainActivity.this);
cdd.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
cdd.show();

我希望这对你有用。

Answer 2

创建自定义警报布局custom_aler_update.xml

然后将此代码复制到Activity：

        AlertDialog basic_reg;
    AlertDialog.Builder builder ;
    builder = new AlertDialog.Builder(ct, R.style.AppCompatAlertDialogStyle);
    LayoutInflater inflater = ((Activity) ct).getLayoutInflater();
    View v = inflater.inflate(R.layout.custom_aler_update, null);
    builder.setView(v);
    builder.setCancelable(false);
    builder.create();
    basic_reg = builder.show();

将此代码复制到样式：

  <style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:textColorPrimary">@color/primaryTextColor</item>
    <item name="android:background">@color/white</item>
</style>

Answer 3

更改背景颜色和文本样式的最简单方法是为Android警报对话框创建自定义主题，如下所示： -

：只需将下面的代码放到styles.xml：

    <style name="AlertDialogCustom" parent="@android:style/Theme.Dialog">
    <item name="android:textColor">#999999</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowTitleStyle">@null</item>
    <item name="android:typeface">monospace</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:textSize">@dimen/abc_text_size_medium_material</item>
    <item name="android:background">#80ff00ff</item>
</style>

：现在自定义事情已经完成，现在只适用于您的alertBuilder对象：

    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this,R.style.AlertDialogCustom);

希望对你有帮助 ！

Answer 4

创建警报对话框布局是这样的

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <Button
        android:id="@+id/btn"
        android:layout_width="match_parent"
        android:text="Custom Alert Dialog"
        android:layout_height="40dp">
    </Button>
</LinearLayout>

并在Activity类上添加以下代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    LayoutInflater inflate = LayoutInflater.from(this);
    alertView = inflate.inflate(R.layout.your_alert_layout, null);
    Button btn= (Button) alertView.findViewById(R.id.btn);

    showDialog();
  }

 public void showDialog(){
        Dialog alertDialog = new Dialog(RecognizeConceptsActivity.this);
        alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        alertDialog.setContentView(alertView);
        alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        alertDialog.show();
    }

Answer 5

它是Alert Dialog的一个类，因此您可以从任何活动调用该类来重用代码。

public class MessageOkFragmentDialog extends DialogFragment {
Typeface Lato;
String message = " ";
String title = " ";
int messageID = 0;

public MessageOkFragmentDialog(String message, String title) {
    this.message = message;
    this.title = title;
}


@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    LayoutInflater inflater = getActivity().getLayoutInflater();

    View convertview = inflater.inflate(R.layout.dialog_message_ok_box, null);


    Constants.overrideFonts(getActivity(), convertview);
    Lato = Typeface
            .createFromAsset(getActivity().getAssets(), "font/Lato-Regular.ttf");


    TextView textmessage = (TextView) convertview
            .findViewById(R.id.textView_dialog);

    TextView textview_dialog_title = (TextView) convertview.findViewById(R.id.textview_dialog_title);

    textmessage.setTypeface(Lato);
    textview_dialog_title.setTypeface(Lato);



    textmessage.setText(message);
    textview_dialog_title.setText(title);



    Button button_ok = (Button) convertview
            .findViewById(R.id.button_dialog);
    button_ok.setTypeface(Lato);

    builder.setView(convertview);
    button_ok.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            dismiss();

        }
    });


    return builder.create();

}
}

同样的Xml文件是：

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"
    android:gravity="center_vertical|center"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:orientation="vertical">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/blue_color"
            android:gravity="center_horizontal"
            android:orientation="horizontal">

            <TextView
                android:id="@+id/textview_dialog_title"
                android:layout_width="wrap_content"
                android:layout_height="50dp"
                android:gravity="center"
                android:textColor="@color/white_color"
                android:textSize="@dimen/txtSize_Medium" />


        </LinearLayout>

        <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="@color/txt_white_color" />

        <TextView
            android:id="@+id/textView_dialog"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_margin="@dimen/margin_20"
            android:textColor="@color/txt_gray_color"
            android:textSize="@dimen/txtSize_small" />

        <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="@color/txt_white_color"
            android:visibility="gone"/>

        <Button
            android:id="@+id/button_dialog"
            android:layout_width="wrap_content"
            android:layout_height="@dimen/margin_40"
            android:layout_gravity="center"
            android:background="@drawable/circular_blue_button"

            android:text="@string/ok"
            android:layout_marginTop="5dp"
            android:layout_marginBottom="@dimen/margin_10"
            android:textColor="@color/txt_white_color"
            android:textSize="@dimen/txtSize_small" />
    </LinearLayout>

</LinearLayout>

Answer 6

Dialog Fragment是创建自定义Alert Dialog的最简单方法。按照上面的代码为对话框创建自定义视图，然后使用Dialog Fragment实现它。将以下代码添加到布局文件中：

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="80dp"
    android:background="#3E80B4"
    android:orientation="vertical">

    <TextView
        android:id="@+id/txt_dia"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:text="Do you realy want to exit ?"
        android:textColor="@android:color/white"
        android:textSize="15dp"
        android:textStyle="bold" />


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#3E80B4"
        android:orientation="horizontal">

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="Yes"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />

        <Button
            android:id="@+id/btn_no"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:layout_marginLeft="5dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="No"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />
    </LinearLayout>

</LinearLayout>

创建自定义警报对话框

cumstomDialog.xml

<ImageView
    android:id="@+id/icon"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:layout_gravity="center"
    android:layout_margin="5dp"
    app:srcCompat="@drawable/error" />

<TextView
    android:id="@+id/title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:fontFamily="@font/muli_bold"
    android:text="Title"
    android:layout_marginTop="5dp"
    android:textColor="@android:color/black"
    android:textSize="15sp" />


<TextView
    android:id="@+id/description"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_marginTop="10dp"
    android:fontFamily="@font/muli_regular"
    android:text="Message"
    android:textColor="@android:color/black"
    android:textSize="12dp" />

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="20dp"
    android:gravity="center"
    android:orientation="horizontal">

    <Button
        android:id="@+id/cancelBTN"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left"
        android:layout_margin="5dp"
        android:background="@drawable/bground_radius_button_white"
        android:text="No"
        android:textColor="@color/black" />

    <Button
        android:id="@+id/acceptBtn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_margin="5dp"
        android:background="@drawable/bground_radius_button"
        android:text="Yes"
        android:textColor="@color/white" />
</LinearLayout>

在您的活动中显示自定义对话框：

  public void showDialog(String title, String des, int icon) {

    final Dialog dialog = new Dialog(this);
    dialog.setContentView(R.layout.custom_dialog);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

    Button cancelBTN = dialog.findViewById(R.id.cancelBTN);
    Button acceptBTN = dialog.findViewById(R.id.acceptBtn);
    TextView tvTitle = dialog.findViewById(R.id.title);
    TextView tvDescription = dialog.findViewById(R.id.description);
    ImageView ivIcon = dialog.findViewById(R.id.icon);

    tvTitle.setText(title);
    tvDescription.setText(des);
    ivIcon.setImageResource(icon);

    cancelBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();
        }
    });

    acceptBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });

    dialog.show();
}

像这样打电话：

showDialog（“Title”，“Message”，R.drawable.warning）;

我发布了我正在使用的kotlin代码，它对我来说很好。您还可以为对话框按钮设置单击侦听器。

这是我的XML代码：

layout_custom_alert_dialog.xml

            listener.onClick(btn_negative)
            dialog.dismiss()
        }
    }

    fun setPoitiveButtonText(text : String)
    {
        btn_positive.text = text
    }


    fun setNegativeButtonText(text : String)
    {
        btn_negative.text = text
    }

    fun setAlertTitle(title : String)
    {
        txt_alert_title.text = title
    }
}

点击侦听器的界面：

onClickListener.kt

interface onClickListener{
    fun onClick(view : View)
}

样本用法

val dialog = mAlertDialog(context)
                dialog.setNegativeButtonText("no i dont")
                dialog.setPoitiveButtonText("yes is do")
                dialog.setAlertTitle("do you like this alert dialog?")

                dialog.setPositiveClickListener(object : onClickListener {
                    override fun onClick(view: View) {
                        Toast.makeText(context, "yes", Toast.LENGTH_SHORT).show()
                    }
                })

                dialog.setNegativeClickListener(object : onClickListener {
                    override fun onClick(view: View) {
                        Toast.makeText(context, "no", Toast.LENGTH_SHORT).show()
                    }
                })

                dialog.show()

我希望这能帮到您！

导入自定义提醒：

        LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.dse_location_list_filter, null);
        final Dialog dialog = new Dialog(Acitvity_name.this);
        dialog.setContentView(view);
        dialog.setCancelable(true);
        dialog.setCanceledOnTouchOutside(true);
        dialog.show();

我喜欢使用tcAron库。 （在此下载：https://github.com/triocoder/tcAron）

1. 进口类： import com.triocoder.tcaron.tcaronlibrary.tcAronDialogs;
2. 写这个： tcAronDialogs.showFancyAlert（MainActivity.this，false，“Text”，“Close”，“ic_hub_white”，0xFFF44336）;
3. 检查文档： https://github.com/triocoder/tcAron/wiki/showFancyAlert

Answer 11

这是一个示例对话框，使用xml创建。

下一个代码xml只是一个例子，设计或视图在这里实现：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffffff">

<ImageView
    android:layout_width="match_parent"
    android:layout_height="120dp"
    android:id="@+id/a"
    android:gravity="center"
    android:background="#DA5F6A"
    android:src="@drawable/dialog_cross"
    android:scaleType="fitCenter" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TEXTO"
    android:id="@+id/text_dialog"
    android:layout_below="@+id/a"
    android:layout_marginTop="20dp"
    android:layout_marginLeft="4dp"
    android:layout_marginRight="4dp"
    android:layout_marginBottom="20dp"
    android:textSize="18sp"
    android:textColor="#ff000000"
    android:layout_centerHorizontal="true"
    android:gravity="center_horizontal" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="30dp"
    android:text="OK"
    android:id="@+id/btn_dialog"
    android:gravity="center_vertical|center_horizontal"
    android:layout_below="@+id/text_dialog"
    android:layout_marginBottom="20dp"
    android:background="@drawable/btn_flat_red_selector"
    android:layout_centerHorizontal="true"
    android:textColor="#ffffffff" />

</RelativeLayout>

这行代码是drawable的资源：

android:src="@drawable/dialog_cross"
android:background="@drawable/btn_flat_red_selector"

你可以做一个类扩展Dialog，也是这样的：

public class ViewDialog {

    public void showDialog(Activity activity, String msg){
        final Dialog dialog = new Dialog(activity);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);
        dialog.setContentView(R.layout.dialog);

        TextView text = (TextView) dialog.findViewById(R.id.text_dialog);
        text.setText(msg);

        Button dialogButton = (Button) dialog.findViewById(R.id.btn_dialog);
        dialogButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });

        dialog.show();

    }
}

最后是你的Activity上的调用形式，例如：

ViewDialog alert = new ViewDialog();
alert.showDialog(getActivity(), "Error de conexión al servidor");

我希望它为你工作。

Answer 12

另一种简单的方法。

步骤1）创建一个具有正确id的布局。

步骤2）在任何您想要的地方使用以下代码。

LayoutInflater factory = LayoutInflater.from(this);
final View deleteDialogView = factory.inflate(R.layout.mylayout, null);
final AlertDialog deleteDialog = new AlertDialog.Builder(this).create();
deleteDialog.setView(deleteDialogView);
deleteDialogView.findViewById(R.id.yes).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        //your business logic 
        deleteDialog.dismiss();
    }
});
deleteDialogView.findViewById(R.id.no).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        deleteDialog.dismiss();    
    }
});

deleteDialog.show();

Answer 13

在values -> style.xml中添加以下主题

<style name="Theme_Dialog" parent="android:Theme.Light">
     <item name="android:windowNoTitle">true</item>
     <item name="android:windowBackground">@android:color/transparent</item>
</style>

在你的onCreateDialog方法中使用这个主题，如下所示：

Dialog dialog = new Dialog(FlightBookActivity.this,R.style.Theme_Dialog);

在xml文件中定义包含标题栏的对话框布局，并将xml文件设置为：

dialog.setContentView(R.layout.your_dialog_layout);

Answer 14

简单首先创建一个类

 public class ViewDialog {

        public void showDialog(Activity activity, String msg){
            final Dialog dialog = new Dialog(activity);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setCancelable(false);
            dialog.setContentView(R.layout.custom_dialogbox_otp);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

            TextView text = (TextView) dialog.findViewById(R.id.txt_file_path);
            text.setText(msg);

            Button dialogBtn_cancel = (Button) dialog.findViewById(R.id.btn_cancel);
            dialogBtn_cancel.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
//                    Toast.makeText(getApplicationContext(),"Cancel" ,Toast.LENGTH_SHORT).show();
                    dialog.dismiss();
                }
            });

            Button dialogBtn_okay = (Button) dialog.findViewById(R.id.btn_okay);
            dialogBtn_okay.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
//                    Toast.makeText(getApplicationContext(),"Okay" ,Toast.LENGTH_SHORT).show();
                    dialog.cancel();
                }
            });

            dialog.show();
        }
    }

然后创建custom_dialogbox_otp

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="330dp"
    android:layout_height="160dp"
    android:background="#00555555"

        android:padding="7dp"
        android:weightSum="100">

        <LinearLayout

                android:gravity="center">

                    android:background="#DA5F6A"
                    android:gravity="center"
                    android:scaleType="fitCenter"
                    android:src="@mipmap/infoonetwo" />

            </LinearLayout>

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                    android:layout_marginRight="30dp"
                    android:layout_weight="50"
                    android:gravity="center|right">

                </LinearLayout>
            </LinearLayout>
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

然后在你的drawable创建xml文件下面。 对于round_layout_white_otp.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <!-- <corners android:radius="10dp" /> -->
    <corners
        android:bottomLeftRadius="18dp"
        android:bottomRightRadius="16dp"
        android:topLeftRadius="38dp"
        android:topRightRadius="36dp" />
    <solid android:color="#C0C0C0" />
    </shape>

对于round_layout_otp.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <!-- <corners android:radius="10dp" /> -->
    <corners
        android:bottomLeftRadius="18dp"
        android:bottomRightRadius="16dp"
        android:topLeftRadius="38dp"
        android:topRightRadius="38dp" />
    <solid android:color="#DA5F6A" />
    </shape>

round_button

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <!-- <corners android:radius="10dp" /> -->
    <corners
        android:bottomLeftRadius="7dp"
        android:bottomRightRadius="7dp"
        android:topLeftRadius="7dp"
        android:topRightRadius="7dp" />
    <solid android:color="#06A19E" />
    </shape>

然后最后使用下面的代码来视觉对话:)

ViewDialog alert = new ViewDialog();
        alert.showDialog(ReceivingOTPRegActivity.this, "OTP has been sent to your Mail ");

你的输出:)

Answer 16

创建自定义对话框的最简单方法：

1. 初始化并显示对话框：

    ViewDialog alertDialoge = new ViewDialog();
    alertDialoge.showDialog(getActivity(), "PUT DIALOG TITLE");

2. 创建方法：

   public class ViewDialog {
   
     public void showDialog(Activity activity, String msg) {
   
       final Dialog dialog = new Dialog(activity);
       dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
       dialog.setCancelable(false);
       dialog.setContentView(R.layout.custom_dialoge_feedback);
   
       TextView text = (TextView) dialog.findViewById(R.id.text_dialog_feedback);
       text.setText(msg);
   
       Button okButton = (Button) dialog.findViewById(R.id.btn_dialog_feedback);
       Button cancleButton = (Button) dialog.findViewById(R.id.btn_dialog_cancle_feedback);
       final EditText edittext_tv = (EditText) dialog.findViewById(R.id.dialoge_alert_text_feedback);
   
       okButton.setOnClickListener(new View.OnClickListener() {
   
           @Override
           public void onClick(View v) {
               //Perfome Action
           }
       });
       cancleButton.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View view) {
               dialog.dismiss();
           }
       });
   
       dialog.show();
   
       }
   }

3. 创建您想要或需要的布局XML。

Answer 17

你可以尝试这个简单的android dialog popup library来削减混乱的对话框代码。在您的活动中使用非常简单。之后，您可以在活动中显示此代码以显示对话框

Pop.on(this).with().title(R.string.title).layout(R.layout.custom_pop).show();

其中R.layout.custom_pop是您想要装饰对话框的自定义布局。

Answer 18

I found this as the easiest way for showing custom dialog.

你有布局your_layout.xml

public void showCustomDialog(final Context context) {
    Dialog dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = inflater.inflate(R.layout.your_layout, null, false);
    findByIds(view);  /*HERE YOU CAN FIND YOU IDS AND SET TEXTS OR BUTTONS*/
    ((Activity) context).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE | WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
    dialog.setContentView(view);
    final Window window = dialog.getWindow();
    window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    window.setBackgroundDrawableResource(R.color.colorTransparent);
    window.setGravity(Gravity.CENTER);
    dialog.show();
}
