java - 在 onLocationChanged 方法中从服务获取纬度/经度

Question

我有一个名为 GPS_Service 的服务。 从另一个 Activity 我想启动此服务并从 onLocationChanged() 方法获取 location.getLatitude() 和 location.getLongitude() 的值。如果 onLocationChanged() 不是静态的，我该怎么做？

提前致谢!

public class GPS_Service extends Service {

private LocationListener listener;
private LocationManager locManager;

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public void onCreate() {
    liveLocs = new ArrayList<>();
    if (PreferenceManager.getDefaultSharedPreferences(GPS_Service
            .this).getString("len_live_locations", "-") != "-") {

    }

    listener = new LocationListener() {
    @Override
        public void onLocationChanged(Location location) {
            Intent i = new Intent("location_update");
            i.putExtra("coordinates", location.getLongitude() + "       " + location
                    .getLatitude());
            sendBroadcast(i);
        }
    }
}

在您的服务中尝试一下:尝试使用Bundle:

Intent intent = new Intent("YourAction");
Bundle bundle = new Bundle();
bundle.put... // put extras you want to pass with broadcast. This is optional
bundle.putString("valueName", "The value you want in the activity");
bundle.putDouble("doubleName", someDouble);
intent.putExtras(bundle)
LocalBroadcastManager.getInstance(context).sendBroadcast(intent);
