I m new to Anders and I m with the following problem. 我写了一份样品申请,其中我有一份意图服务,首先检查所有地点供应商,以找到最后的知道地点。 如果最后几个地点都没有提供足够准确(或及时)的地点,则要求地点主管采用广播用户的更新方法。 每次广播接收人使用收听方法时,都应检查地点,看看是否准确和/或足够及时。 我在打算服务中还有一个时间表,该服务最终会中断,并且应当检查是否获得准确和/或及时的足够地点更新。 问题Im在于,我不知道如何将广播接收器获得的地点数据重新输入意图服务。 象这样的景象应该容易做,但我已经过去了数天。 我认为,这样做的唯一途径是将数据写给广播接收器的一台ite,然后将这些记录重新读作意图服务,但似乎不必要地复杂。 是否有任何人知道将数据归还意图服务的适当途径? 我是否甚至应该利用广播接收器要求广播更新? 这样做是否容易? 这里是法典

public class GetLocationService extends IntentService {

    public GetLocationService() {
        super("something");
    }

    LocationManager locationManager;
    long maxFixLateness;
    float maxFixPosUncertainty;
    boolean usableLocObtained;
    Location bestLoc = null;
    float bestLocScore = 0;
    Intent locChangeI;
    PendingIntent pLocChangeI;

    @Override
    final protected void onHandleIntent(Intent intent) {
        maxFixLateness = 30000;
        maxFixPosUncertainty = 30;
        long curTime = System.currentTimeMillis();
        LocationManager locationManager = (LocationManager) this
                .getSystemService(Context.LOCATION_SERVICE);
        // Check for a usable location fix
        List<string> matchingProviders = locationManager.getAllProviders();
        for (String provider : matchingProviders) {
            Location location = locationManager.getLastKnownLocation(provider);
            if (location != null) {
                // ...some code to check if the location is accurate or timely
                // enough
            }
        }
        if (bestLoc == null) {
            locChangeI = new Intent(this, HandleLocationUpdateReceiver.class);
            pLocChangeI = PendingIntent.getBroadcast(this, 0, locChangeI,
                    PendingIntent.FLAG_UPDATE_CURRENT);
            usableLocObtained = false;
            locationManager.requestLocationUpdates(
                    LocationManager.NETWORK_PROVIDER, 0, 0, pLocChangeI);
            locationManager.requestLocationUpdates(
                    LocationManager.GPS_PROVIDER, 0, 0, pLocChangeI);
            // Call the timer that will periodically check to see if a usable
            // location has been obtained.
            new LocFixCheckTimer(60000, 30, 1000);
        }
    }

    private class LocFixCheckTimer {

        Timer timer;
        long numChecks;

        public LocFixCheckTimer(long initSearchTime, long maxRechecks,
                long recheckFreq) {
            numChecks = maxRechecks;
            timer = new Timer();
            // Wait 2 seconds before checking for a fix again
            timer.schedule(new CheckLocTask(), initSearchTime, recheckFreq);
        }

        class CheckLocTask extends TimerTask {

            public void run() {
                if (numChecks > 0) {
                    if (usableLocObtained == true) {
                        // I want to use the location data obtained from the
                        // HandleLocationUpdateReceiver s onReceive method
                        // but I don t how to get that data here.
                    }
                } else {
                    // Cancel the timer. We ve timed-out on searching
                    // for a usable location fix
                    timer.cancel();
                }
                --numChecks;
            }
        }
    }
}

这里是广播接收器:

public class HandleLocationUpdateReceiver extends BroadcastReceiver
{ 
  @Override
  public void onReceive(Context context, Intent intent)
  {
    Location loc = (Location) intent.getExtras().get(LocationManager.KEY_LOCATION_CHANGED);
    if (loc != null)
    {
      double lat = loc.getLatitude();
      double lon = loc.getLongitude();
      // Do some checking to see how accurate and timely the location is
      // here and somehow get it back to the intent service.
    }
  }
}

得到帮助!
