百度地圖定位簽到功能,百度地圖簽到
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" >

mOption.setIsNeedLocationDescribe(true);//可選,設定是否需要地址描述

mOption.setIsNeedLocationDescribe(true);//可選,預設false,設定是否需要位置語義化結果,可以在BDLocation.getLocationDescribe裡得到,結果類似於“在北京天安門附近”
