有没有显示无模式对话框的对话框？该对话框允许用户与对话框之前的屏幕上的内容进行交互，但是如果被按下，则还允许用户与对话框进行交互？
我知道Toasts，但是它们不允许与弹出窗口进行交互。
我知道对话框，但是它们是模态的，不允许与背景交互。
我知道通知，但是我想要在屏幕上可见的东西。
我基本上希望能够玩游戏或类似的东西，并且弹出窗口显示我有新的电子邮件或类似的东西。我可以单击它查看我的电子邮件，但是如果我想继续玩游戏，可以等待它消失。在Android中可以吗？
是，创建一个样式为Theme.Dialog的活动。这是一个正常的活动，看起来像一个对话框，同时处于无模式且接受事件。
示例：
<activity android:name=".activity.dialog.PhotoDialog"
android:label="@string/photo_dialog_title"
android:theme="@android:style/Theme.Dialog"/>
编辑：
确实Theme.Dialog模糊了基础活动并使之不可访问。我在这里有一个类似的要求，我必须显示带有文本和取消按钮的上传进度对话框。主要问题在于设置WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL和重置WindowManager.LayoutParams.FLAG_DIM_BEHIND。
创建具有自定义内容的对话框：
if (progressDialog == null) {
progressDialog = new Dialog(activityRequestingProgressDialog);
progressDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
progressDialog.setContentView(R.layout.progress_upload);
progressBar = (ProgressBar) progressDialog.findViewById(R.id.progressBar);
progressText = (TextView) progressDialog.findViewById(R.id.progressText);
progressText.setText("0 %");
progressText.setTextSize(18);
Button buttonCancel = (Button) progressDialog.findViewById(R.id.btnCancel);
buttonCancel.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
cancelProgressDialog();
stopUpload("Upload cancelled.");
}
});
Window window = progressDialog.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
window.setGravity(Gravity.BOTTOM);
progressDialog.show();
}
progressText.setText(text);
progressBar.setProgress(percent);
这是此对话框的布局：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/progressDialog"
android:orientation="vertical"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_centerVertical="true">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textSize="18sp"
android:padding="10dp"
android:text="@string/progress_title"/>
<LinearLayout android:id="@+id/progressDialog"
android:orientation="horizontal"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:padding="10dp"
android:layout_centerVertical="true">
<ProgressBar android:id="@+id/progressBar"
android:layout_width="150dp"
android:layout_height="34dp"
android:paddingRight="10dp"
android:max="100"
android:progress="0"
android:fadingEdge="vertical"
style="?android:attr/progressBarStyleHorizontal"/>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="@+id/progressText"
android:paddingRight="10dp"/>
<Button android:layout_height="40dp"
android:layout_width="80dp"
android:id="@+id/btnCancel"
android:text="@string/dialog_cancel"/>
</LinearLayout>
</LinearLayout>
只需在对话框中添加FLAG_NOT_TOUCH_MODAL标志
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
我的实现有点黑，但是还允许按钮被后台窗口捕获
_wm = this.getWindowManager();
LayoutInflater layoutInflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
_view = layoutInflater.inflate(R.layout.notification, null);
_params = new WindowManager.LayoutParams();
_params.height = android.view.ViewGroup.LayoutParams.WRAP_CONTENT;
_params.width = android.view.ViewGroup.LayoutParams.WRAP_CONTENT;
_params.flags =
// this is to keep button presses going to the background window
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
// this is to enable the notification to recieve touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL;
// background transparant
_params.format = PixelFormat.TRANSLUCENT;
_gravity = Gravity.TOP;//Gravity.BOTTOM;
_wm.addView(_view, _params);
只是您不想使用活动或Theme.Dialog的DialogFragment冒险的补充

PhotoChooserFragment
public class photoChooserFragment
extends DialogFragment {
onItemSelectedListener listener;
ImageView imgCamera, imgGallery, imgRemovePhoto;
TextView tvCamera, tvGallery, tvRemovePhoto;
public interface onItemSelectedListener {
void onItemSelected(int position);
}
public void onItemSelected(int position) {
listener.onItemSelected(position);
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
// Activities containing this fragment must implement its listener.
if (!(activity instanceof onItemSelectedListener)) {
throw new IllegalStateException(
"Activity must implement fragment's callbacks.");
}
listener = (onItemSelectedListener) activity;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.chooser, null, false);
imgCamera = view.findViewById(R.id.camera);
imgGallery = view.findViewById(R.id.gallery);
imgRemovePhoto = view.findViewById(R.id.removePhoto);
tvCamera = view.findViewById(R.id.tvCamera);
tvGallery = view.findViewById(R.id.tvGallery);
tvRemovePhoto = view.findViewById(R.id.tvRemovePhoto);
Window window = getDialog().getWindow();
window.requestFeature(Window.FEATURE_NO_TITLE);
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
WindowManager.LayoutParams windowLP = window.getAttributes();
//window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
// WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
window.addFlags(WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);
//window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
window.setGravity(Gravity.BOTTOM);
windowLP.gravity = Gravity.BOTTOM;
window.setAttributes(windowLP);
getDialog().setCanceledOnTouchOutside(true);
return view;
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
imgCamera.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
onItemSelected(1);
}
});
tvCamera.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
onItemSelected(1);
}
});
imgGallery.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
onItemSelected(2);
}
});
tvGallery.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
onItemSelected(2);
}
});
imgRemovePhoto.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
onItemSelected(3);
}
});
tvRemovePhoto.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
onItemSelected(3);
}
});
}
@Override
public void onDetach() {
super.onDetach();
// Reset the active listener interface to null.
listener = null;
}
}
然后在您的活动中添加界面
implements photoChooserFragment.onItemSelectedListener
并确保已实施
@Override
public void onItemSelected(int position){
switch (position){
case 1: //camera
GetImageFromCamera();
break;
case 2: //gallery
ChooseImageFromGallery();
break;
}
}
现在您可以调用该片段，一个按钮将起作用，在我使用的是floatingbutton上
faBtnCamera.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Show menu
photoChooserFragment dialog = new photoChooserFragment();
dialog.show(getSupportFragmentManager(), "chooser");
}
});
