Androiod中解决HorizontalScrollView和ScrollView相互嵌套导致滑动卡的方法

最近在开发中遇到HorizontalScrollView嵌套ScrollView导致滑动卡的情况，急横向水平滑动的View和垂直水平滑动的View，都在接收处理滑动时间，但是这种情况下触摸事件就会发生冲突。导致滑动非常卡，甚至出现程序停止响应。这种情况下我们需要重写view。下面是两个简单的例子，重写水平滑动View只接收水平方向上滑动的事件。我们使用手势GestureDetector来作区分。完整的源码请参考附件。

public class CustomHScrollView extends HorizontalScrollView{
private GestureDetector mGestureDetector;
private View.OnTouchListener mGestureListener;

private static final String TAG = "CustomHScrollView";


        /**
         * @function CustomHScrollView constructor
         * @param context  Interface to global information about an application environment.
         *
         */
        public CustomHScrollView(Context context) {
                super(context);
                // TODO Auto-generated constructor stub
            mGestureDetector = new GestureDetector(new HScrollDetector());
            setFadingEdgeLength(0);
        }
       
       
        /**
         * @function CustomHScrollView constructor 
         * @param context Interface to global information about an application environment.
         * @param attrs A collection of attributes, as found associated with a tag in an XML document.
         */
        public CustomHScrollView(Context context, AttributeSet attrs) {
            super(context, attrs);
            // TODO Auto-generated constructor stub
        mGestureDetector = new GestureDetector(new HScrollDetector());
        setFadingEdgeLength(0);
        }

        /**
         * @function  CustomHScrollView constructor 
         * @param context Interface to global information about an application environment.
         * @param attrs A collection of attributes, as found associated with a tag in an XML document.
         * @param defStyle style of view
         */
        public CustomHScrollView(Context context, AttributeSet attrs,
                        int defStyle) {
                super(context, attrs, defStyle);
                // TODO Auto-generated constructor stub
            mGestureDetector = new GestureDetector(new HScrollDetector());
            setFadingEdgeLength(0);
        }
       
        @Override
   public boolean onInterceptTouchEvent(MotionEvent ev) {
        return super.onInterceptTouchEvent(ev) && mGestureDetector.onTouchEvent(ev);
   }
    
       // Return false if we're scrolling in the y direction  
   class HScrollDetector extends SimpleOnGestureListener {
           @Override
       public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {       
            if(Math.abs(distanceX) > Math.abs(distanceY)) {
                   return true;
            }
          
            return false;
       }
   }

}
