java – Gplus用户身份验证和获取用户在同一活动中的位置

在我的活动中,我正在实施以下给定的课程

com.google.android.gms.common.GooglePlayServicesClient.ConnectionCallbacks,
com.google.android.gms.common.GooglePlayServicesClient.OnConnectionFailedListener,
com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks,
com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener

这两个界面用于通过google plus验证用户.

com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks,
com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener

这些是用于获取用户当前位置的

com.google.android.gms.common.GooglePlayServicesClient.ConnectionCallbacks,
com.google.android.gms.common.GooglePlayServicesClient.OnConnectionFailedListener

这些类中的方法是相同的.

@Override
public void onConnected(Bundle connectionHint) {}

和

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {}

由于这些方法具有相同的参数和相同的返回类型,因此在同一类中不能有两个.所以我认为我需要确定从Bundle或ConnectionResult调用了哪个接口.我怎么能这样做？我的意思是我需要检查哪个关键值？如果需要任何澄清请评论.
谢谢

解决方法:

将接口实现为匿名成员声明怎么样？

public class Ac {

    private GooglePlayServicesClient.OnConnectionFailedListener psConnectionFailedListener =
            new GooglePlayServicesClient.OnConnectionFailedListener() {

                @Override
                public void onConnectionFailed(ConnectionResult connectionResult) {
                    // implementation
                }
            };

    private GooglePlayServicesClient.ConnectionCallbacks psConnectionCallbacks =
            new GooglePlayServicesClient.ConnectionCallbacks() {

                @Override
                public void onConnected(Bundle bundle) {
                    // implementation
                }

                @Override
                public void onDisconnected() {
                    // implementation
                }
            };

    private GoogleApiClient.ConnectionCallbacks googleConnectionCallbacks =
            new GoogleApiClient.ConnectionCallbacks() {

                @Override
                public void onConnected(Bundle bundle) {
                    // implementation
                }

                @Override
                public void onConnectionSuspended(int i) {
                    // implementation
                }
            };

    private GoogleApiClient.OnConnectionFailedListener googleConnectionFailedListener =
            new GoogleApiClient.OnConnectionFailedListener() {

                @Override
                public void onConnectionFailed(ConnectionResult connectionResult) {
                    // implementation
                }
            };
}
