Android ValueAnimator EditText波濤洶涌的動畫

Question

我使用Value Animator爲我的視圖創建滑動動畫。問題是，當子視圖是EditText動畫是不連貫的。代碼：

private ValueAnimator SlideAnimator(int start,int end, View mView) 
    { 
     ValueAnimator animator = ValueAnimator.OfInt(start, end); 
     animator.SetDuration(2500); 
     animator.Update += 
      (object sender, ValueAnimator.AnimatorUpdateEventArgs e) => { 
      var value = (int)animator.AnimatedValue; 
      ViewGroup.LayoutParams layoutParams = mView.LayoutParameters; 
      layoutParams.Height = value; 
      mView.LayoutParameters=layoutParams; 
      mView.RequestLayout(); 
    }; 
    return animator; 

    if (wrappedChildren[position].Visibility == ViewStates.Visible) 
     { 
      int finalHeight = wrappedChildren[position].Height; 
      ValueAnimator mAnimator = SlideAnimator(finalHeight, 0, wrappedChildren[position]); 
      mAnimator.Start(); 
      mAnimator.AnimationEnd += (sender, args) => 
      { 
       SetSectionVisibility(position, ViewStates.Gone); 
      }; 
     } 
     else 
     { 
      int widthSpec = View.MeasureSpec.MakeMeasureSpec(0, MeasureSpecMode.Unspecified); 
      int heightSpec = View.MeasureSpec.MakeMeasureSpec(0, MeasureSpecMode.Unspecified); 
      wrappedChildren[position].Measure(widthSpec,heightSpec); 
      int measuredHeight = wrappedChildren[position].MeasuredHeight; 
      ValueAnimator mAnimator = SlideAnimator(0, measuredHeight,wrappedChildren[position]); 
      mAnimator.Start(); 
      SetSectionVisibility(position, ViewStates.Visible); 

     } 

wrappedChildren [位置]是查看保存的EditText子視圖

你有沒有嘗試過在模擬器或真實設備？它可能會因模擬器而變得遲鈍...
