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
< attr path = " /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.MapView android:id="@+id/bmapView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:clickable="true" />
C#代码如下
