Answer 1

It is good, you change the Buttons to ImageButtons and use android:src instead of android:background For example :

<ImageButton
android:id="@+id/button_00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/jerry"
android:onClick="btn_click" />

You can set your image runtime as well

ImageButton button=findViewById(R.id.button_00);
button.setImageResource(R.drawable.jerry);
