動畫滯後只在銀河兆豐2個手機

Question

我創建了打開/關閉和生長/在同一時間收縮滑動抽屜動畫。我使用ValueAnimator和AnimatorUpdateListener內部操作視圖的邊距來增加或減少（增大/縮小）它的大小。同時，ValueAnimator正在處理開啓和關閉。對於Galaxy Mega 2手機，這個動畫非常不穩定;不光滑。所有其他新舊手機似乎都能正常工作。有什麼辦法可以解決這個問題嗎？

  // close drawer 
      ValueAnimator animator = ValueAnimator.ofInt(0, 100); 
      animator.setInterpolator(new AccelerateInterpolator()); 
      animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() { 

       @Override 
       public void onAnimationUpdate(ValueAnimator animation) { 
        float ratio = ((Integer) animation.getAnimatedValue()/100); 

        // moves the drawer to the left and reduces its size by changing its margins 
        mDrawerParams.setMargins((int) (mLeftMargin * ratio), (Integer) animation.getAnimatedValue(), 
          0, (Integer) animation.getAnimatedValue()); 
        rlDrawer.setLayoutParams(mDrawerParams); 
} 

這裏是我怎麼打開我的抽屜裏

  // open drawer 
      ValueAnimator animator = ValueAnimator.ofInt(100, 0); 
      animator.setInterpolator(new AccelerateInterpolator()); 
      animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() { 

       @Override 
       public void onAnimationUpdate(ValueAnimator animation) { 
        float ratio = ((Integer) animation.getAnimatedValue()/100); 

        // moves the drawer to the right and increases its size by changing its margins 
        mDrawerParams.setMargins((int) (mLeftMargin * ratio), (Integer) animation.getAnimatedValue(), 
          0, (Integer) animation.getAnimatedValue()); 
        rlDrawer.setLayoutParams(mDrawerParams); 
}

如果更改的LayoutParams上查看名爲onRequesLayout，有滯後。你需要改變屬性。更改translation_x，scale_x，scale_y屬性。例如：

Animator animator = ObjectAnimator.ofFloat(drawerLayout, View.TRANSLATION_X, 0, (float));
