滚动时的Android动画

Question

我想在android中做一个像Jquery的动画滚动（在此网页中工作时，当您点击顶层菜单的选项）。可能吗？我已经看到存在scrollTo但可以做动画而不喜欢跳转。非常感谢你。

使用ObjectAnimator，这是滚动到顶部的样品：

public void scroolToTop() { 
       int x = 0; 
       int y = 0; 
     ObjectAnimator xTranslate = ObjectAnimator.ofInt(mScrollView, "scrollX", x); 
     ObjectAnimator yTranslate = ObjectAnimator.ofInt(mScrollView, "scrollY", y); 

     AnimatorSet animators = new AnimatorSet(); 
     animators.setDuration(1000L); 
     animators.playTogether(xTranslate, yTranslate); 
     animators.addListener(new AnimatorListener() { 

      @Override 
      public void onAnimationStart(Animator arg0) { 
       // TODO Auto-generated method stub 
      } 

      @Override 
      public void onAnimationRepeat(Animator arg0) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onAnimationEnd(Animator arg0) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onAnimationCancel(Animator arg0) { 
       // TODO Auto-generated method stub 

      } 
     }); 
     animators.start(); 
    }
