我的活动会打开一个对话框。当它关闭时，我需要ReloadTable()执行该函数。所以我正在尝试使用setOnDismissListener但它没有被触发。有人可以帮助我做错什么吗？

public class MyActivity extends Activity implements DialogInterface.OnCancelListener{
@Override
public void onCreate(Bundle state) {
.....
alertDialog.setOnCancelListener(this);
alertDialog.show();
}
@Override
public void onCancel(DialogInterface dialog) {
dialog.dismiss();
.....
}
}

You have to setOnCancelListener to the AlertDialog.Builder:
您必须将 OnCancelListener 设置为 AlertDialog.Builder：
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
this);
alertDialogBuilder.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
dialogmenu = false;
}
})

In this case you should use alertDialog.setOnCancelListener(listener),and alertDialog.setOnDismissListenerworks with dismissDialog(id).
在这种情况下，您应该使用alertDialog.setOnCancelListener(listener), 并alertDialog.setOnDismissListener使用dismissDialog(id).

OK...I figured it out myself.
好吧...我自己想通了。
I had to implement DialogInterface.OnCancelListenerand add the onCancel()method. It worked!
我必须实现DialogInterface.OnCancelListener并添加该onCancel()方法。有效！

I found the real problem.
我发现了真正的问题。
You should call .show in the dialog, not in the builder.
您应该在对话框中调用 .show ，而不是在构建器中调用。
Try it :)
尝试一下 ：）

Use following code
使用以下代码
final AlertDialog.Builder builder = new AlertDialog.Builder(MyActivity.this);
final View dailogView = LayoutInflater.from(MyActivity.this).inflate(R.layout.dialog_layout, null);
builder.setView(dailogView);
final AlertDialog dialog=builder.create();
dialog.show();
DismissListener
关闭监听器
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialogInterface) {
// your code after dissmiss dialog
}
});
