Android 在ScrollView中嵌入ViewPage后ViewPage不能很好的工作的问题解决

解决办法：重写ScrollView，如下代码所示：

public class MyScrollView extends ScrollView{
    private GestureDetector mGestureDetector;
    View.OnTouchListener mGestureListener;

    public MyScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
        mGestureDetector = new GestureDetector(context, new YScrollDetector());
        setFadingEdgeLength(0);
    }

    @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;
        }
    }
}

最好给大家附上原文地址，上面有为什么这样做的详细介绍，我这里就不在赘述了哈。
