Android Location Client无法解析方法

我正在尝试通过onConnected方法中的位置客户端请求位置更新.我的片段实现了LocationListener,GooglePlayServicesClient.ConnectionCallbacks和GooglePlayServicesClient.OnConnectionFailedListener.

代码看起来像这样.

public class AnimatedMapFragment extends SupportMapFragment 
                implements LocationListener,
                           GooglePlayServicesClient.ConnectionCallbacks,
                           GooglePlayServicesClient.OnConnectionFailedListener {

    private LocationRequest mLocationRequest;
    private LocationClient mLocationClient;

    ...

    mLocationRequest = LocationRequest.create();
    mLocationRequest.setInterval(5000);
    mLocationRequest.setFastestInterval(1000);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    mLocationClient = new LocationClient(this.getActivity(), this, this);

    ...

    @Override
    public void onConnected(Bundle bundle) {
        mLocationClient.requestLocationUpdates(mLocationRequest, this);
    }

并且错误是“找不到适合requestLocationUpdates(LocationRequest,AnimatedMapFragment)的方法”这是非常令人困惑的,因为在位置客户端的文档中,有requestLocationUpdates的这个定义.

public void requestLocationUpdates(LocationRequest request,LocationListener listener)

有谁看到我错过了什么？

如果其他人遇到这个问题,那就搞清楚了.确保您正在导入：

com.google.android.gms.location.LocationClient;

我正在导入android.location.LocationClient.
