Android ScrollView与ViewPager滑动冲突

前段时间做项目碰到在ScrollView里添加ViewPager，但是发现ViewPager的左右滑动和ScrollView的滑动冲突了，解决这个问题的方法是重写ScrollView。

代码：

 public class CustomScrollView extends ScrollView {

     private GestureDetector mGestureDetector;
     View.OnTouchListener mGestureListener;

     public CustomScrollView(Context context, AttributeSet attrs) {
         super(context, attrs);
         mGestureDetector = new GestureDetector(context, new YScrollDetector());
     }

     public CustomScrollView(Context context, AttributeSet attrs, int defStyle) {
         super(context, attrs, defStyle);
         mGestureDetector = new GestureDetector(context, new YScrollDetector());
     }

     public CustomScrollView(Context context) {
         super(context);
         mGestureDetector = new GestureDetector(context, new YScrollDetector());
     }

     @Override
     public boolean onInterceptTouchEvent(MotionEvent ev) {
         return super.onInterceptTouchEvent(ev)
                 && mGestureDetector.onTouchEvent(ev);
     }

     // Return false if we're scrolling in the x direction
     class YScrollDetector extends SimpleOnGestureListener {
         @Override
         public boolean onScroll(MotionEvent e1, MotionEvent e2,
                 float distanceX, float distanceY) {
             if (Math.abs(distanceY) > Math.abs(distanceX)) {
                 return true;
             }
             return false;
         }
     }

 }
