解决ViewPager和SlidingPaneLayout的事件冲突

来源：互联网发布：java字符流读取视频编辑：程序博客网时间：2024/04/29 12:53

　最近在做一个项目需要用到ViewPager加载广告图，布局中需要侧滑，用了android V4包里的SlidingPaneLayout控件，项目中使用的时候，发现在滑动中ViewPager和SlidingPaneLayout滑动冲突了，当手指从左向右滑动时，ViewPager的滑动事件被SlidingPaneLayout屏蔽了，只能执行SlidingPaneLayout的事件，而从右往左滑时，则正常。

　　下面的处理代码，是转载的，可以直接复制使用，暂时没发现问题，有问题以后再修改。

　　这里说一下处理步骤，自己新建一个类，继承于SlidingPaneLayout，然后把这个类添加到你所要布局的XML文件里，这样就可以了。下面贴代码。

package com.zuzuChe.view;import android.content.Context;import android.support.v4.view.MotionEventCompat;import android.support.v4.widget.SlidingPaneLayout;import android.util.AttributeSet;import android.view.MotionEvent;import android.view.ViewConfiguration;/** * Created by apaojun on 2015/2/12. */public class PagerEnabledSlidingPaneLayout extends SlidingPaneLayout {    private float mInitialMotionX;    private float mInitialMotionY;    private float mEdgeSlop;    public PagerEnabledSlidingPaneLayout(Context context) {        this(context, null);    }    public PagerEnabledSlidingPaneLayout(Context context, AttributeSet attrs) {        this(context, attrs, 0);    }    public PagerEnabledSlidingPaneLayout(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);        ViewConfiguration config = ViewConfiguration.get(context);        mEdgeSlop = config.getScaledEdgeSlop();    }    @Override    public boolean onInterceptTouchEvent(MotionEvent ev) {        switch (MotionEventCompat.getActionMasked(ev)) {            case MotionEvent.ACTION_DOWN: {                mInitialMotionX = ev.getX();                mInitialMotionY = ev.getY();                break;            }            case MotionEvent.ACTION_MOVE: {                final float x = ev.getX();                final float y = ev.getY();                // The user should always be able to "close" the pane, so we only check                // for child scrollability if the pane is currently closed.                if (mInitialMotionX > mEdgeSlop && !isOpen() && canScroll(this, false,                        Math.round(x - mInitialMotionX), Math.round(x), Math.round(y))) {                    // How do we set super.mIsUnableToDrag = true?                    // send the parent a cancel event                    MotionEvent cancelEvent = MotionEvent.obtain(ev);                    cancelEvent.setAction(MotionEvent.ACTION_CANCEL);                    return super.onInterceptTouchEvent(cancelEvent);                }            }        }        return super.onInterceptTouchEvent(ev);    }}
