I solved the problem in the following way: I downloaded the icon here and changed the Button to ImageButton
<ImageButton android:id="@+id/button_C" android:tag="C" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingBottom="16dp" android:paddingLeft="33dp" android:paddingRight="33dp" android:layout_gravity="center" android:paddingTop="16dp" android:src="@drawable/ic_backspace_black_18dp" /> java java
