先下载百度地图http://lbsyun.baidu.com/sdk/download?selected=mapsdk_basicmap,mapsdk_searchfunction,mapsdk_lbscloudsearch,mapsdk_calculationtool

• 百度地图绑定库文件

新建一个BindingsLibrary项目，并把刚下载的BaiduLBS_Android.jar添加到项目的Jars文件夹下，更改BaiduLBS_Android.jar的属性中的”生成操作”属性为EmbeddedJar

生成些项目，如果遇到这样的错误：

VersionInfo”: 成员名不能与它们的封闭类型相同

打开项目中的Transforms的Metadate.xml，在<metadata>节点添加如下代码

  <
attrpath
=
"
/api/package[@name='com.baidu.mapapi']/class[@name='VersionInfo']/field[@name='VERSION_INFO']
"name
=
"
name
"
>
VersionInfos
</
attr
>

因为在C#中不能定义和类名相同的类成员（构造函数除外）

• 创建andorid项目

在项目中创建一个libs文件夹，把下载的百度地图包中的.so文件添加进来，并在属性上设置成AndroidNativeLibrary

添加权限和设置百度地图访问应用Key

<application android:label="BaiduMapDemo" android:icon="@drawable/Icon"><meta-data android:name="com.baidu.lbsapi.API_KEY" android:value="这个需要注册百度开放平台申请Android的Key" /></application><uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.INTERNET" /><!-- 这个权限用于获取wifi的获取权限，wifi信息会用来进行网络定位--><uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission><!-- 用于读取手机当前的状态--><uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
在布局文件中添加地图控件（注意大小写：）<com.baidu.mapapi.map.MapViewandroid:id="@+id/bmapView"android:layout_width="fill_parent"android:layout_height="fill_parent"android:clickable="true" />

C#代码如下

using Android.Runtime;

using Android.OS;
using Com.Baidu.Mapapi.Map;
