在黑莓應用程序中從GPS獲取當前位置

Question

如何從黑莓應用程序中的GPS獲取當前位置。我試圖從模擬器Locationmanager method獲得位置，但是在我的設備中（Storm 2使用wifi），我無法獲得當前經緯度。

我的代碼

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 
    } 
}

我發現這個第一的位置我找了風暴的問題：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.
