Кнопка активности Android onClick () работает медленно

В моем событии кнопки Activity работает медленно, в этом действии все кнопки работают нормально, но они реагируют с небольшой задержкой около 2/3 секунды. Я делаю здесь, когда я нажимаю кнопку, он меняет весь фон кнопки. Я не могу понять, в чем проблема, пожалуйста, помогите мне!
