Android ScrollView取消惯性滚动的方法

scrollview中惯性滚动的效果，想让这个scrollview慢一点滑动或者接近drag(拖拽)操作，就提出了添加阻尼的说法。只要重新fling方法即可，将velocity值极至缩小。

实例如下：

public class customhorizontalscrollview extends horizontalscrollview {
  private context context;
  private scrollviewlistenner listenner;
  private customhorizontalscrollview currentview;

  public customhorizontalscrollview(context context) {
    super(context);
    // todo auto-generated constructor stub
    this.context = context;
  }

  public customhorizontalscrollview(context context, attributeset attrs) {
    super(context, attrs);
    // todo auto-generated constructor stub
    this.context = context;
  }

  public customhorizontalscrollview(context context, attributeset attrs,
                   int defstyleattr) {
    super(context, attrs, defstyleattr);
    // todo auto-generated constructor stub
    this.context = context;
  }

  @override
  public boolean ontouchevent(motionevent ev) {
    // todo auto-generated method stub
    currentview = this;
    return super.ontouchevent(ev);
  }

  @override
  protected void onscrollchanged(int l, int t, int oldl, int oldt) {
    // todo auto-generated method stub
    if (null != listenner) {
      this.listenner.onscrollchanged(currentview, l, t, oldl, oldt);
    }
    super.onscrollchanged(l, t, oldl, oldt);
  }

  public interface scrollviewlistenner {
    public void onscrollchanged(customhorizontalscrollview view, int l,
                  int t, int oldl, int oldt);
  }

  public void setscrollviewlistenner(scrollviewlistenner listenner) {
    this.listenner = listenner;
  }

  /**
  *
  *阻尼：1000为将惯性滚动速度缩小1000倍，近似drag操作。
  @override
  public void fling(int velocity) {
    super.fling(velocity / 1000);
  }
  */
}
