Question

我复制粘贴了此link中的以下代码。当我使用有源设备而不是模拟器时，没有显示位置信息。甚至Gps已启用

public class UseGps extends Activity

{

    /** Called when the activity is first created. */

    @Override
    public void onCreate (Bundle savedInstanceState)

    {

        super.onCreate (savedInstanceState);

        setContentView (R.layout.main);

        /* Use the LocationManager class to obtain GPS locations */

        LocationManager mlocManager = (LocationManager) getSystemService (Context.LOCATION_SERVICE);

        LocationListener mlocListener = new MyLocationListener ();

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

    }

    /* Class My Location Listener */

    public class MyLocationListener implements LocationListener

    {

        @Override
        public void onLocationChanged (Location loc)

        {

            loc.getLatitude ();

            loc.getLongitude ();

            String Text = "My current location is: " + "Latitud = " + loc.getLatitude () + "Longitud = " + loc.getLongitude ();

            Toast.makeText (getApplicationContext (), Text, Toast.LENGTH_SHORT).show ();

        }

        @Override
        public void onProviderDisabled (String provider)

        {

            Toast.makeText (getApplicationContext (), "Gps Disabled", Toast.LENGTH_SHORT).show ();

        }

        @Override
        public void onProviderEnabled (String provider)

        {

            Toast.makeText (getApplicationContext (), "Gps Enabled", Toast.LENGTH_SHORT).show ();

        }

        @Override
        public void onStatusChanged (String provider, int status, Bundle extras)

        {

        }

    }/* End of Class MyLocationListener */

}/* End of UseGps Activity */

Answer 1

看起来很正确。如果您没有忘记添加权限，可能是您的设备无法找到卫星。试着在建筑物外测试它。或者只是尝试使用

修改

mlocManager.requestLocationUpdates(mlocManager.getBestProvider(new Criteria(), true), 0, 0, mlocListener);

而不是LocationManager.GPS_PROVIDER。

Answer 2

看起来不错。也许你的设备真的找不到卫星。尝试使用假的gps应用程序运行此代码，例如https://play.google.com/store/apps/details?id=com.lexa.fakegps&hl=ru
