沒有位置修復GPS - Android

Question

我複製粘貼下面的代碼從這link。當我使用有源設備而不是仿真器時，沒有顯示位置信息。即使GPS啓用

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

它看起來是正確的。如果您還沒有忘記添加權限，那麼您的設備可能找不到衛星。試着在建築物外面進行測試。 或者只是嘗試使用

編輯：

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

，而不是LocationManager.GPS_PROVIDER。

Answer 2

看起來沒問題。 也許你的設備真的找不到衛星。嘗試運行這樣的代碼與這樣的假gps應用程序https://play.google.com/store/apps/details?id=com.lexa.fakegps&hl=ru
