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;
        }
    }

}
