I popped up activity_lock.xml with the code above. However, the form of the button I set in activity_lock.xml doesn’t apply, and a default button of grey rectangles is created as shown below. Why? Any help would be greatly appreciated.

enter image description here

I’m looking forward to the form being applied normally.
