[操作系统]百度地图定位签到功能


1. 注意 key 一定要在activity 前面

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme" >
<service
android:name="com.baidu.location.f"
android:enabled="true"
android:process=":remote" >
</service>

<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="6dsXhPU5WWHcBxGwQtHZKIGfZZBorMZ5" />
2 .
<com.baidu.mapapi.map.MapView
android:id="@+id/map_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

</com.baidu.mapapi.map.MapView>

mOption.setNeedDeviceDirect(false);//可选,设置是否需要设备方向结果

mOption.setIgnoreKillProcess(true);//可选,默认true,定位SDK内部是一个SERVICE,并放到了独立进程,设置是否在stop的时候杀死这个进程,默认不杀死
mOption.setIsNeedLocationDescribe(true);//可选,默认false,设置是否需要位置语义化结果,可以在BDLocation.getLocationDescribe里得到,结果类似于“在北京天安门附近”
