ViewPager嵌套禁止外层滑动

public class XyViewPager extends ViewPager {
    private boolean scrollble = true;
/**
     * 如果不滚动把事件断续传给子view处理
     * @param ev
     * @return
     */
    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (!scrollble)
            return false;
        return super.onInterceptTouchEvent(ev);
    }
 }
