我希望我的 RTT 应用程序能够控制我们何时/是否接收位置更新,无论是来自 GPS 还是网络。我可以使用 GpsStatus.Listener 轻松控制 GPS 状态,但我找不到网络更新的等价物。例如,如果我们进入没有网络或 wifi 的区域,该事件将触发,或者会发生超时,如 GpsStatus.GPS_EVENT_SATELLITE_STATUS 所涵盖的情况
代码片段在这里:
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);
