**Android 百度地图 SDK v3.0.0 添加覆盖物Marker与InfoWindow的使用**

我们先看效果图片：

我下载过 百度的 官网演示，感觉写的不是很详细。 我在开发的时候也磕磕碰碰的，注释也的很清楚了，下面是代码：

先看布局文件：

一： Fragment 碎片的布局文件 fragment\_check\_map：

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >
    
        
    
        <com.baidu.mapapi.map.MapView
            android:id="@+id/mv_baidumap"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clickable="true" />
    
    </LinearLayout>

二： 我们点击 Marker 弹出窗口的布局文件 baidumap\_infowindow：

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/bg_infowindow"
        android:paddingTop="15dp"
        android:paddingBottom="30dp"
        android:paddingLeft="15dp"
        android:paddingRight="15dp"
        android:orientation="vertical" >
    
        <TextView
            android:id="@+id/tv_entname"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="企业名称：样子嘻嘻嘻有限公司" />
    
        <TextView
            android:id="@+id/tv_checkdept"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="检查部门：安监局" />
        
        <TextView
            android:id="@+id/tv_checkuser"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="检查人员：啊嘎嘎嘎" />
        
        <TextView
            android:id="@+id/tv_checktime"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="检查时间：2016-01-09" />
    </LinearLayout>
