解决ScrollView嵌套百度地图滑动冲突

一、问题描述

scrollview中嵌套百度地图时会出现滑动冲突，地图无法滑动的情况。

二、期望结果

焦点在地图上时，只有地图移动，焦点在地图外部时，可以滑动scrollview。

三、解决方法

自定义包裹地图的容器

package com.aldx.kangdasupervisor.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.LinearLayout;

/**

public class BaiduMapContainer extends LinearLayout {
    private MyScrollview scrollView;
    public BaiduMapContainer(Context context) {
        super(context);
    }
    public BaiduMapContainer(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    public void setScrollView(MyScrollview scrollView) {
        this.scrollView = scrollView;
    }
    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_UP) {
            scrollView.requestDisallowInterceptTouchEvent(false);
        } else {
            scrollView.requestDisallowInterceptTouchEvent(true);
        }
        return false;
    }
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return true;
    }
}

自定义scrollview

package com.aldx.kangdasupervisor.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.ViewConfiguration;
import android.widget.ScrollView;

/**

public class MyScrollview extends ScrollView {
    private int downX;
    private int downY;
    private int mTouchSlop;

    public MyScrollview(Context context) {
        super(context);
        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
    }

    public MyScrollview(Context context, AttributeSet attrs) {
        super(context, attrs);
        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
    }

    public MyScrollview(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent e) {
        int action = e.getAction();
        switch (action) {
            case MotionEvent.ACTION_DOWN:
                downX = (int) e.getRawX();
                downY = (int) e.getRawY();
                break;
            case MotionEvent.ACTION_MOVE:
                int moveY = (int) e.getRawY();
                if (Math.abs(moveY - downY) > mTouchSlop) {
                    return true;
                }
        }
        return super.onInterceptTouchEvent(e);
    }
}

绑定scrollview与MapView

bannerContainer.setScrollView(myScrollview);

布局

<com.aldx.kangdasupervisor.view.BaiduMapContainer
                android:id="@+id/bannerContainer"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

                <com.baidu.mapapi.map.TextureMapView
                    android:id="@+id/bmapView"
                    android:layout_width="match_parent"
                    android:layout_height="200dp"
                    android:clickable="true" />

            </com.aldx.kangdasupervisor.view.BaiduMapContainer>
