我僅僅是想要個(gè)定位结胀，接入個(gè)SDK做卵
下面網(wǎng)上找的一個(gè)工具類，可用。颊亮。。

獲取位置權(quán)限：

 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

工具類：

            textView.append("經(jīng)度: " + location.getLongitude() + " 緯度: " + location.getLatitude()+ "\n");
        }

        @Override
