Android 如何超时RequestLocationUpdate？

当未找到

GPS

修复程序时，代码将无限期地卡在

活套中

。 我想添加一个超时，这样如果没有找到

GPS

fix，它应该从

looper

中出来并执行代码的其余部分

如果你能帮我解决这个问题，我将不胜感激

public class service_task extends Service {

    @SuppressLint("MissingPermission")
    @Override
    public void onCreate() {
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO: Return the communication channel to the service.
        throw new UnsupportedOperationException("Not yet implemented");
    }

    private class ServerThread extends Thread implements LocationListener {

        public LocationManager locationManager = null;
        public String msg = "default";
        public String id = "default";
        private Location mLocation = null;
        public Socket socket = null;
        public int serviceid;


        public ServerThread(LocationManager locationManager, int startid) {
            super("UploaderService-Uploader");
            this.locationManager = locationManager;
            this.serviceid=startid;          
        }

        @SuppressLint("MissingPermission")
        public void run() {


            Looper.prepare();
            this.locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
            Looper.loop();


            if (mLocation!=null) {
                msg = "GPS data:" + mLocation;
            }else{
                msg ="No GPS data";
            }

            stopSelf(serviceid);
        }

        @Override
        public void onLocationChanged(Location location) {
            mLocation = location;
            Log.d("D", String.valueOf(location));
            this.locationManager.removeUpdates(this);
            Looper.myLooper().quit();
        }

        @Override
        public void onStatusChanged(String s, int i, Bundle bundle) {

        }

        @Override
        public void onProviderEnabled(String s) {

        }

        @Override
        public void onProviderDisabled(String s) {

        }


    }

    @SuppressLint("MissingPermission")
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {


        Log.d("D", "startcommand");
        LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        ServerThread thread = new ServerThread(locationManager,startId);
        thread.start();
        return START_REDELIVER_INTENT;
    }
}

创建一个使用

活套的
处理程序
：
处理程序=新处理程序（Looper.myLooper（））
然后使用
handler.postDelayed（Runnable，long）
发布一个新的
Runnable
，在给定延迟后取消位置更新并退出
活套
