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().

@Kormilsev Anatoliy has answered correct and I am just improving. So in the class you inherit from Dialog class just override the method:

@Override
public void onWindowFocusChanged (boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    height = getWindow().getDecorView().getHeight();
}
