在我的活動中,我正在實(shí)施以下給定的課程

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

這兩個界面用于通過google plus驗(yàn)證用戶.

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

這些是用于獲取用戶當(dāng)前位置的

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

這些類中的方法是相同的.

@Override
public void onConnected(Bundle connectionHint) {}

和

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {}

由于這些方法具有相同的參數(shù)和相同的返回類型,因此在同一類中不能有兩個.所以我認(rèn)為我需要確定從Bundle或ConnectionResult調(diào)用了哪個接口.我怎么能這樣做？我的意思是我需要檢查哪個關(guān)鍵值？如果需要任何澄清請?jiān)u論.
謝謝

解決方法:

將接口實(shí)現(xiàn)為匿名成員聲明怎么樣？

public class Ac {

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

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