How about this:

Button yourBtn = (Button) findViewById.(R.id.yourBtn);

int btnSize=yourBtn.getLayoutParams().width;
yourBtn.setLayoutParams(new LayoutParams(btnSize, btnSize));

When should this code be called? I call it in `onCreate` but the `btnSize` is -2. – Felix Aug 22 '16 at 13:37

You have to do it programmatically. XML layout is only for static stuff.

After the button have been draw at least once on the screen you will resize it by setting a new LayoutParams to it with the desired values.
