Manifest File

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

我只需要用户所在的确切位置。运行此应用程序后，我无法从模拟器和设备中获得任何信息……（Samsung Galaxy GT S5360）。此外，我只需要 lat & long & 需要将其作为参数传递给其他方法，因此也欢迎任何其他解决方案。

问候，

利用

locManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener);

伊斯特多夫

locManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, 0, 0, mlocListener);

就我而言，这对我很有帮助。

还请添加以下权限。

android.permission.INTERNET
android.permission.ACCESS_COARSE_LOCATION
android.permission.ACCESS_FINE_LOCATION
android.permission.ACCESS_MOCK_LOCATION
