I do not understand very well what Android Studio refers to with this

I think you should overwrite the performClick () method because you do not try to put your switch in this

@Override
public boolean performClick(View view, MotionEvent event){
    switch(){...}
    return true;
}

or use onTouch ()

@override
public boolean onTouch(View view, MotionEvent event) {
    switch(){...}
    return true;
}
