定位没有无线网络就不起作用

Question

我有一个简单的应用程序，它使用LocationClient。位置会更新，直到启用无线网络。

例：

1. 3G on, wifi on (connected or not), GPS on- work
2. 3G on, wifi on (connected or not), GPS off- work
3. 3G off, wifi on (connected or not), GPS off- work
4. 3G on/off, wifi off, GPS on/off- doesn't work 

法典：

public class PlayPositionProvider implements PositionProvider, FastestUpdate, GooglePlayServicesClient.ConnectionCallbacks, GooglePlayServicesClient.OnConnectionFailedListener {
    private static final String LOG_TAG = "PLAY_POSITION_PROVIDER";
    private long period, fastest;
    private LocationClient client;
    private final Context context;
    private final PositionListener positionListener;
    private LocationListener listener = new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            Log.v(LOG_TAG, "LOCATION UPDATE");
            positionListener.onPositionUpdate(location);
        }
    };
    public PlayPositionProvider(Context context, long period, long fastest, PositionListener positionListener) {
        this.context = context;
        this.positionListener = positionListener;
        this.period = period;
        this.fastest = fastest;
    }
    @Override
    public void setUpdateInterval(long interval) {
        request.setInterval(interval);
        this.period = interval;
    }
    @Override
    public void setFastestInterval(long fastestInterval) {
        request.setFastestInterval(fastestInterval);
        this.fastest = fastestInterval;
    }
    private final LocationRequest request = LocationRequest.create();
    @Override
    public void onConnected(Bundle bundle) {
        Log.v(LOG_TAG, "onConnected()");
        request.setInterval(period);
        request.setFastestInterval(fastest);
        request.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        client.requestLocationUpdates(request, listener);
    }
    @Override
    public void onDisconnected() {
        Log.v(LOG_TAG, "onDisconnected()");
        client.removeLocationUpdates(listener);
    }
    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        Log.v(LOG_TAG, "NOT IMPLEMENTED onConnectionFailed()");
    }
    @Override
    public void startUpdates() {
        client = new LocationClient(context, this, this);
        client.connect();
    }
    @Override
    public void stopUpdates() {
        client.disconnect();
    }
}

Answer 1

两件事：

1. 我们不知道您是否正在检查GooglePlayServices是否可用。
2. 有了requestLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);，您就表示您对GPS数据感兴趣。我不确定，但这可能是问题所在
