SlidingPanelLayout плохо работает справа налево в Android

Я создаю SlidingPanelLayout справа налево для цели filter. Панель работает нормально, она выходит с правой стороны и выполняет анимацию, но когда анимация останавливается, она сразу переходит на левую сторону, но мне нужно соотношение 70% означает right side panel came out 70% of the total screen, и при повторном нажатии он переходит в задний план, и отображается полная активность.

Когда анимация в первый раз останавливается, боковая панель переходит в левую сторону на скриншоте. Но я хочу, чтобы она была правой.

Снимок экрана:

но я хочу отобразить его на стороне записи, и при повторном щелчке он пойдет вправо и снова скроется.

Заранее спасибо.
