我想创建一个背景颜色为白色且消息颜色为黑色的Toast消息。我的祝酒词是：
Toast.makeText(Logpage.this, "Please Give Feedback...", 3000).show();
我想用另一种不在onCreate()中的方法创建它。
您可以创建如下的自定义Toast消息：
Toast toast = new Toast(context);
toast.setDuration(Toast.LENGTH_LONG);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.your_custom_layout, null);
toast.setView(view);
toast.show();
您可以将一个textview放在布局文件中，并根据需要提供背景和文本颜色。
您还可以执行以下操作，不需要额外的自定义布局文件：
Toast toast = Toast.makeText(context, R.string.string_message_id, Toast.LENGTH_LONG);
View view = toast.getView();
view.setBackgroundResource(R.drawable.custom_background);
TextView text = (TextView) view.findViewById(android.R.id.message);
/*Here you can do anything with above textview like text.setTextColor(Color.parseColor("#000000"));*/
toast.show();
更改Toast颜色，无需任何额外的布局，2018年
这是一个非常简单的方法，我发现改变Toast的实际图像背景的颜色以及文本颜色，它不需要任何额外的布局或任何XML更改：
Toast toast = Toast.makeText(context, message, duration);
View view = toast.getView();
//Gets the actual oval background of the Toast then sets the colour filter
view.getBackground().setColorFilter(YOUR_BACKGROUND_COLOUR, PorterDuff.Mode.SRC_IN);
//Gets the TextView from the Toast so it can be editted
TextView text = view.findViewById(android.R.id.message);
text.setTextColor(YOUR_TEXT_COLOUR);
toast.show();
更改默认的Toast文本颜色和背景颜色试试这样。
Toast toast = Toast.makeText(MainActivity.this, "Please Give Feedback...", Toast.LENGTH_LONG);
View view = toast.getView();
//To change the Background of Toast
view.setBackgroundColor(Color.TRANSPARENT);
TextView text = (TextView) view.findViewById(android.R.id.message);
//Shadow of the Of the Text Color
text.setShadowLayer(0, 0, 0, Color.TRANSPARENT);
text.setTextColor(Color.BLACK);
text.setTextSize(Integer.valueOf(getResources().getString(R.string.text_size)));
toast.show();
您可以使用以下代码自定义android原生吐司
/**
* ShowToast
*/
public class ShowToast {
public ShowToast(Context context, String info) {
Toast toast = Toast.makeText(context, Html.fromHtml("<font color='#e3f2fd' ><b>" + info + "</b></font>"), Toast.LENGTH_LONG);
toast.setGravity(Gravity.TOP, 0, 0);
toast.show();
}
}
如果要更改背景，则必须在toast中使用自定义布局
创建一个布局文件toast.xml，看看你的toast应如何看，如下所示：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:color/background_dark">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is a custom toast."
android:textColor="@android:color/white"
android:layout_gravity="center_vertical" />
</LinearLayout>
要在java文件中显示toast，请输入以下代码：
public void showCustomAlert()
{
Context context = getApplicationContext();
// Create layout inflator object to inflate toast.xml file
LayoutInflater inflater = getLayoutInflater();
// Call toast.xml file for toast layout
View toast = inflater.inflate(R.layout.toast, null);
Toast toast = new Toast(context);
// Set layout to toast
toast.setView(toast);
toast.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL,
0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.show();
}
Toast toast= Toast.makeText(YOUR ACTIVITY NAME ,Toast.LENGTH_SHORT);
View view =toast.getView();
view.setBackgroundColor(Color.GREEN); //any color your want
toast.show();
添加到@AndroidKiller的答案，您还可以设置gravity和自定义TextView等等：
Toast toast = Toast.makeText(context, context.getResources().getString(resID), Toast.LENGTH_LONG);
LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE );
View toastView = li.inflate(R.layout.toast_hint_layout, null);
TextView text = (TextView) toastView.findViewById(R.id.hint_text_tv);
text.setText(resID);
toast.setView(toastView);
toast.setDuration(Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toastView.setBackgroundResource(R.drawable.toast_9_patch);
toast.show();
请注意，您的背景可绘制应该是nine-patch PNG
您甚至可以将ImageView和多个TextViews放入XML中，如下所示：
<LinearLayout android:id="@+id/layout_root"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:layout_width="32dp"
android:layout_height="43dp"
android:src="@drawable/lightbulb"
/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:orientation="vertical"
>
<TextView
android:id="@+id/hint_text_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#ccc"
android:textSize="14dp"
/>
<TextView
android:id="@+id/hint_text_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="(disable hints in preferences)"
android:textColor="#555"
android:textSize="11dp"
/>
</LinearLayout>
</LinearLayout>
static void CustomToast(Context context, String text, int duration,
@Nullable Integer backgroundColor,
@Nullable Integer textColor){
Toast t = Toast.makeText(context,text,duration);
if (backgroundColor != null)
t.getView()
.setBackgroundTintList(ColorStateList.valueOf(backgroundColor));
if (textColor != null)
((TextView)t.getView().findViewById(android.R.id.message))
.setTextColor(textColor);
t.show();
}
