How to get dialog size?

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().getAttributes().height; it only returns -2, which is a constant for WRAP_CONTENT attribute which I set to dialog. How can I get the size of it. I want to know the siye for the background image.

Solution

  • Actually, in Android it doesn't work like in iOS - you can't get the size of the View itself, what you can do, though, is to ask for the size of the ROOT layout of that view.

    e.g.:

    myDialog.this.findViewById(R.id.dialog_root_layout).getHeight());
