RefreshScrollviewLayout下嵌套ViewPager横向滑动冲突解决

最近做的有个项目，主要是轮播图这部分，RefreshScrollviewLayout下嵌套viewpager ，在滑动轮播图的时候，发现如果横向滑动稍微有点斜的话，就会触动RefreshScrollviewLayout的下拉刷新。这肯定是事件传递的问题，

通过这两篇文章解决的问题：
重写SwipeRefreshLayout(出于google):

import android.content.Context;

import android.support.v4.widget.SwipeRefreshLayout;

import android.util.AttributeSet;

import android.view.MotionEvent;

import android.view.ViewConfiguration;

 

/**

 */

 

public class MySwipeRefreshLayout extendsSwipeRefreshLayout {

    privatefloat startY;

    privatefloat startX;

    // 记录viewPager是否拖拽的标记

    privateboolean mIsVpDragger;

    privatefinal int mTouchSlop;

 

    publicMySwipeRefreshLayout(Context context, AttributeSet attrs) {

        super(context, attrs);

        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();

    }

 

    @Override

    publicboolean onInterceptTouchEvent(MotionEvent ev) {

        intaction = ev.getAction();

        switch(action) {

            caseMotionEvent.ACTION_DOWN:

                // 记录手指按下的位置

                startY = ev.getY();

                startX = ev.getX();

                // 初始化标记

                mIsVpDragger =false;

                break;

            caseMotionEvent.ACTION_MOVE:

                // 如果viewpager正在拖拽中，那么不拦截它的事件，直接return false；

                if(mIsVpDragger) {

                    returnfalse;

                }

 

                // 获取当前手指位置

                floatendY = ev.getY();

                floatendX = ev.getX();

                floatdistanceX = Math.abs(endX - startX);

                floatdistanceY = Math.abs(endY - startY);

                // 如果X轴位移大于Y轴位移，那么将事件交给viewPager处理。

                if(distanceX > mTouchSlop && distanceX > distanceY) {

                    mIsVpDragger =true;

                    returnfalse;

                }

                break;

            caseMotionEvent.ACTION_UP:

            caseMotionEvent.ACTION_CANCEL:

                // 初始化标记

                mIsVpDragger =false;

                break;

        }

        // 如果是Y轴位移大于X轴，事件交给swipeRefreshLayout处理。

        returnsuper.onInterceptTouchEvent(ev);

    }

}

重写ScrollView(出于google):

import android.content.Context;

import android.util.AttributeSet;

import android.view.MotionEvent;

import android.widget.ScrollView;

 

/**

 * Created by admin on 2017/5/5.

 */

 

public class VerticalScrollView extendsScrollView {

    privatefloat xDistance, yDistance, lastX, lastY;

 

    publicVerticalScrollView(Context context, AttributeSet attrs) {

        super(context, attrs);

    }

 

    @Override

    publicboolean onInterceptTouchEvent(MotionEvent ev) {

        switch(ev.getAction()) {

            caseMotionEvent.ACTION_DOWN:

                xDistance = yDistance = 0f;

                lastX = ev.getX();

                lastY = ev.getY();

                break;

            caseMotionEvent.ACTION_MOVE:

                finalfloat curX = ev.getX();

                finalfloat curY = ev.getY();

                xDistance += Math.abs(curX - lastX);

                yDistance += Math.abs(curY - lastY);

                lastX = curX;

                lastY = curY;

                if(xDistance > yDistance)

                    returnfalse;

        }

 

        returnsuper.onInterceptTouchEvent(ev);

    }

}
