    1.1UserLocation的关键API
        LocationManager:用于管理Android的用户定位服务
        LocationProviders:提供多种定位方式供开发者选项

    1.2定位方式的分类：
        GPS卫星定位：
            <uses-permisssion ...android.permission.ACCESS_FINE_LOCATION />
        NETWORK定位信号接收塔、WiFi介入点：
            <uses-permission ...android.permission.ACCESS_FINE_LOCATION/>
            或
            <uses-permission ...android.permission.ACCESS_COARSE_LOCATION/>

     1.3获取用户当前位置的步骤
     在AndroidManifest.xml文件中声明相应权限
     选择LocationManager对象
     选择LocationProvider对象
     绑定LocationListener对象
