GpsStatus.Listener不触发对网络状态的变化 [英] GpsStatus.Listener not firing on network status changes

问题描述

我希望我的RTT的应用程序，以便能够在/我们是否正在接收位置更新，无论从GPS或网络控制。我可以很容易地控制GPS状态与GpsStatus.Listener，但我无法找到相当于网络中的更新。例如，该事件将触发，如果我们进入一个地区，没有网络或无线网络，或将出现超时像覆盖GpsStatus.GPS_EVENT_SATELLITE_STATUS的情况下

codeS片段在这里：

  mGPSReceiver =（LocationManager）this.getSystemService（Context.LOCATION_SERVICE）;
    mLocationListener =新LocationListener的（）{
        私人的位置mLastLocation;

        @覆盖
        公共无效onLocationChanged（最终位置定位）{
            // 东东
        }

        @覆盖
        公共无效onProviderDisabled（最后弦乐提供商）{
            如果（mGPSReceiver.getProviders（真）.size（）== 0）{// WRONG
                PhoneStatusService.this.setGPSStatus（假）;
            }
        }

        @覆盖
        公共无效onProviderEnabled（最后弦乐提供商）{
        }

        @覆盖
        公共无效onStatusChanged（最后弦乐供应商，最终诠释状态，最终捆绑演员）{
        }
    };
    mGPSListener =新GpsStatus.Listener（）{
        @覆盖
        公共无效onGpsStatusChanged（最终诠释事件）{
            开关（事件）{
                案例GpsStatus.GPS_EVENT_STARTED：
                    打破;
                案例GpsStatus.GPS_EVENT_FIRST_FIX：
                    setGPSStatus（真正的）;
                    打破;
                案例GpsStatus.GPS_EVENT_STOPPED：
                    打破;
                案例GpsStatus.GPS_EVENT_SATELLITE_STATUS：
                    最终布尔isGPSFixing =（SystemClock.elapsedRealtime（） -  mLastLocationMillis）所述; GPS_TIMEOUT;
                    setGPSStatus（isGPSFixing）;
                    打破;
                默认：
                    打破;
            }
        }
    };
    mGPSReceiver.addGpsStatusListener（mGPSListener）;
    mGPSReceiver.requestLocationUpdates（LocationManager.GPS_PROVIDER，GPS_FIX_TIME，0，
            mLocationListener）;
    mGPSReceiver.requestLocationUpdates（LocationManager.NETWORK_PROVIDER，GPS_FIX_TIME，0，
            mLocationListener）;
 

解决方案

创建接收网络更新一个BroadcastReceiver。

I want my RTT app to be able to control when/whether we are receiving location updates, no matter from GPS or network. I can easily control GPS status with a GpsStatus.Listener but I cannot find the equivalent for network updates. For example, the event would fire if we enter an area with no network or wifi, or a timeout will occur like in the case covered by GpsStatus.GPS_EVENT_SATELLITE_STATUS

Codes snippets here:

    mGPSReceiver = (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
    mLocationListener = new LocationListener() {
        private Location mLastLocation;

        @Override
        public void onLocationChanged(final Location location) {
            // STUFF
        }

        @Override
        public void onProviderDisabled(final String provider) {
            if (mGPSReceiver.getProviders(true).size() == 0) { // WRONG
                PhoneStatusService.this.setGPSStatus(false);
            }
        }

        @Override
        public void onProviderEnabled(final String provider) {
        }

        @Override
        public void onStatusChanged(final String provider, final int status, final Bundle extras) {
        }
    };
    mGPSListener = new GpsStatus.Listener() {
        @Override
        public void onGpsStatusChanged(final int event) {
            switch (event) {
                case GpsStatus.GPS_EVENT_STARTED:
                    break;
                case GpsStatus.GPS_EVENT_FIRST_FIX:
                    setGPSStatus(true);
                    break;
                case GpsStatus.GPS_EVENT_STOPPED:
                    break;
                case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
                    final boolean isGPSFixing = (SystemClock.elapsedRealtime() - mLastLocationMillis) < GPS_TIMEOUT;
                    setGPSStatus(isGPSFixing);
                    break;
                default:
                    break;
            }
        }
    };
    mGPSReceiver.addGpsStatusListener(mGPSListener);
    mGPSReceiver.requestLocationUpdates(LocationManager.GPS_PROVIDER, GPS_FIX_TIME, 0,
            mLocationListener);
    mGPSReceiver.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, GPS_FIX_TIME, 0,
            mLocationListener);

解决方案

Create a BroadCastReceiver that receives network updates.
