百度地图 Marker 点击弹出窗口

Marker InfoWindow Fragment

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" >

    <!-- 百度地图的 MapView -->

    <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>
