android提供LoacationManager类来获取自己的经纬度。也可以通过反向地理编码发送http给google返回一个确定值给自己再在解析显示到textview上(Geocoding API)。
首先需要申明权限 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.INTERNET" /> FINE权限对应的是GPS功能权限， COARSE对应的是NETWORK权限， Internet对应的是联网权限。
