If the dialog is dismissed,I want to do something for my background.So I want to know if the dialog is dismissed
@Ken Wolf has a great answer to this question.
Just wanted to add that onDismissListener
was only introduced in API 17
. If you are trying to support something lower, you can use onCancelListener
, which is not as good but covers cases like backButton and tapping outside of the AlertDialog.
http://developer.android.com/reference/android/content/DialogInterface.OnCancelListener.html#onCancel(android.content.DialogInterface)
public Dialog createDialog() {
Dialog d = new Dialog(this);
d.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
// do something
}
});
}
You can use an onDismissListener
http://developer.android.com/reference/android/content/DialogInterface.OnDismissListener.html
public Dialog createDialog() {
Dialog d = new Dialog(this);
d.setOnDismissListener(new OnDismissListener() {
@Override
public void onDismiss(final DialogInterface arg0) {
// do something
}
});
return d;
}
If you are using a DialogFragment
just override onDismiss()
http://developer.android.com/reference/android/app/DialogFragment.html#onDismiss(android.content.DialogInterface)
I noticed that the onDismissListener
is called even when you select one of the options in the alert (Yes/No/Neutral button). For me onCancelListener
was the best option since I needed something that tracked an explicit closing of the dialog by clicking outside the alert area.
When dialog closed, you can use dialog.setOnDismissListener
at the following code with the usage of an updated dialog code.
private void ShowDialog() {
View view = LayoutInflater.from(ActivityMain.this).inflate(R.layout.dialog, null);
dialog = new Dialog(ActivityMain.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(true);
dialog.setCanceledOnTouchOutside(true);
dialog.addContentView(view, new RelativeLayout.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT));
Button dialogBtn = (Button) dialog.findViewById(R.id.button);
dialogBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(final DialogInterface arg) {
//when dialog closed
}
});
}
