GpsStatus.Listener未觸發網絡狀態更改

Question

我希望我的RTT應用能夠控制我們何時/是否接收位置更新，無論是來自GPS還是網絡。我可以使用GpsStatus.Listener輕鬆控制GPS狀態，但我無法找到網絡更新的等同物。例如，如果我們沒有網絡或WiFi進入一個區域的事件將觸發，或者超時將通過GpsStatus.GPS_EVENT_SATELLITE_STATUS覆蓋的情況下發生像

代碼網頁摘要這裏：

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);

創建一個BroadcastReceiver接收網絡更新。
