在黑莓应用程序中从GPS获取当前位置

Question

如何从黑莓应用程序中的GPS获取当前位置。我试图从模拟器Locationmanager method获得位置，但是在我的设备中（Storm 2使用wifi），我无法获得当前经纬度。

我的代码

private class LocationListenerImpl implements LocationListener { 
    public void locationUpdated(LocationProvider provider, Location location) { 
     if (location.isValid()) { 
      heading = location.getCourse(); 
      longitude = location.getQualifiedCoordinates().getLongitude(); 
      latitude = location.getQualifiedCoordinates().getLatitude(); 
      altitude = location.getQualifiedCoordinates().getAltitude(); 
      speed = location.getSpeed(); 

      // This is to get the Number of Satellites 
      String NMEA_MIME = "application/X-jsr179-location-nmea"; 
      satCountStr = location.getExtraInfo("satellites"); 
      if (satCountStr == null) { 
       satCountStr = location.getExtraInfo(NMEA_MIME); 
      } 

      // this is to get the accuracy of the GPS Cords 
      QualifiedCoordinates qc = location.getQualifiedCoordinates(); 
      accuracy = qc.getHorizontalAccuracy(); 
     } 
    } 

    public void providerStateChanged(LocationProvider provider, int newState) { 
     // no-op 
    } 
}

我发现这个第一的位置我找了风暴的问题：If you run the above code on your BlackBerry device (for instance a Storm), you will get a "GPS not allowed" LocationProvider exception. You need to get your code signed if you want to use the BlackBerry Storm with GPS in your app. To do this, you need to buy a $20 certificate from RIM.
