How to get dialog size?

Question

I am looking for a way to get size of a custom dialog. I went through this question, but the only answer given is pretty useless, because if I try mDialog.getWindow().

Answer 1

In case, if you have your own XML layouts for custom dialog.

    /* whatever you want here */

In activity:

    final Dialog dialog = new Dialog(this);
    dialog.setContentView(R.layout.popup_gameover);

    dialog.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface d) {
            View view = dialog.findViewById(R.id.dialog_main_layout);
            int width = view.getWidth();
            int height = view.getHeight();

            ...
        }
    });

This width and height exacly as expected.
