I had the same problem of getButton() returning null. Just reorder the calls so that you show() the dialog before trying to access its buttons:
AlertDialog alertDialog = builder.create(); alertDialog.show(); Button button = (Button) alertDialog.getButton(BUTTON_POSITIVE); // edit the button size I'm not sure if you can then edit the button size after getting a reference to it, but this might be useful in the future.
