wie man mit einem queue in android?? java

Ich muss wissen, wie man mit einem queue in android-java-code. Ich will Feuer eine Methode, bei der die Warteschlange nicht leer ist. Kann mir jemand Tipps geben über dieses...

Derzeit implementierte ich einen timer-task. Diese Klasse Häufig sieht, den status der queue. Wenn die Warteschlange nicht leer ist, wird es das Feuer der Methode.

Ich will wissen, alternative Möglichkeiten, dies zu tun..

public class GSMLocationTask extends TimerTask
{
Handler TDGetDeviceLocHandler;

int myLatitude, myLongitude;
int cid;
int lac;
double latitude;
double longitude;
TelephonyManager telephonyManager;
GsmCellLocation cellLocation;
LocationSendTask lst;

public GSMLocationTask(LocationSendTask locSendtask) {
    //TODO Auto-generated constructor stub
    this.lst = locSendtask;
    this.telephonyManager = (TelephonyManager)TrackDriodApplication.getAppContext().getSystemService(TrackDriodApplication.getAppContext().TELEPHONY_SERVICE);
    this.cellLocation = (GsmCellLocation) telephonyManager.getCellLocation();
}


@Override
public void run() 
{
    Log.d("GSMLocationTask", "GSM Location task Start run...");

       //cid = cellLocation.getCid();
       //lac = cellLocation.getLac();
       cid = 256229;//cellLocation.getCid();
       lac = 30310;//cellLocation.getLac();
       try 
       {
           //new TDGetDeviceLocation().execute(null, null, null); 

           if(RqsLocation(cid, lac))
            {
                latitude = (float)myLatitude/1000000;
                longitude = (float)myLongitude/1000000;
                Log.d("GSMLocationTask", "Lat :" +latitude +" Long :"+longitude);
            }

           DataTransaction dtra = new DataTransaction();
           ServerSettings ss = new ServerSettings();
           ss = dtra.getDeviceSettings(TrackDriodApplication.getAppContext());
           String deviceID = String.valueOf(ss.getDeviceID());
           Log.d("GSMLocationTask", "locationSend obj create");
           LocationSend loc = new LocationSend();
           Log.d("GSMLocationTask", "set lat");
           loc.setLatitude(Double.toString(latitude));
           Log.d("GSMLocationTask", "set long");
           loc.setLongitude(Double.toString(longitude));
           Log.d("GSMLocationTask", "set devid");
           loc.setDeviceID(deviceID);
           Log.d("GSMLocationTask", "set set datetime");
           loc.setDateTime(getCurrentTime());

           Log.d("GSMLocationTask", "add loc to queue sart");
           lst.addLocationToQueue(loc);
           Log.d("GSMLocationTask", "add loc to queue end");
       } 
       catch (Exception e)
