我已经使用各自的方法集成了 google 和 facebook 注册。但是签名成功后,我想打开不同的活动,同样用户可以去各种不同的活动。我使用了操作栏,我可以在其中提供从用户登录的任何一个帐户中退出的选项。当我处于与主要活动不同的活动中时,如何退出用户。我遇到了一个异常,我无法将 apiclient 参考(用于 google)和会话参考(用于 facebook)传递给另一个活动。请帮忙。提前致谢。

从谷歌注销:

只需将其添加到您的新活动中,您希望您的 google+ 注销按钮在那里:

@Override
protected void onStart() {
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();
    mGoogleApiClient.connect();
    super.onStart();
}

接下来您可以在按钮上设置 setOnClickListener:

signout.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
      Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
              new ResultCallback<Status>() {
                  @Override
                  public void onResult(Status status) {
                      // ...
                      Toast.makeText(getApplicationContext(),"Logged Out",Toast.LENGTH_SHORT).show();
                      Intent i=new Intent(getApplicationContext(),MainActivity.class);
                      startActivity(i);
                  }
              });
  }
});

从脸书注销:

public static void callFacebookLogout(Context context) {
Session session = Session.getActiveSession();
if (session != null) {

    if (!session.isClosed()) {
        session.closeAndClearTokenInformation();
        //clear your preferences if saved
    }
} else  {

    session = new Session(context);
    Session.setActiveSession(session);

    session.closeAndClearTokenInformation();
        //clear your preferences if saved

 }

}

从谷歌注销:

@Override
public void onClick(View view) {
if (view.getId() == R.id.sign_out_button) {
if (mGoogleApiClient.isConnected()) {
  Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
  mGoogleApiClient.disconnect();
  mGoogleApiClient.connect();
  }

只需添加您的新活动:

 @Override
        protected void onStart() {
            mGoogleApiClient.connect();
            super.onStart();
        }

接着

@Override
    public void onClick(View v)  {
            switch (v.getId()) {
                case R.id.sign_out_button2:

                        Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
                        mGoogleApiClient.disconnect();

从 Facebook 注销非常简单

只需添加以下代码

LoginManager.getInstance().logOut();

然后,您可以通过进一步添加以下代码将用户重定向到登录活动

LoginManager.getInstance().logOut();
Intent intent = new Intent(CurrentActivity.this, LoginActivity.class);
startActivity(intent);
finish();

所以你 logoutFromFacebook 的最终代码是

public void logoutFromFacebook(){
    LoginManager.getInstance().logOut();
    Intent intent = new Intent(CurrentActivity.this, LoginActivity.class);
    startActivity(intent);
    finish();
}

现在只需在您的注销按钮事件上调用该方法。

首先对于 Facebook 注销:

LoginManager.getInstance().logOut();

如果您尝试从其他活动或片段中注销,这会给您带来错误,例如 Facebook sdk 未初始化。然后首先你必须像这样初始化 facebook sdk:

FacebookSdk.sdkInitialize(your context here);

然后从经理注销。

谷歌注销的次要:

首先,您必须检查谷歌客户端是否已连接,如果已连接,则调用注销代码:

if (mGoogleApiClient.isConnected())
   Auth.GoogleSignInApi.signOut(mGoogleApiClient);

这里 mGoogleApiClient 是 GoogleApiClient 的对象。

从 Facebook 注销。

public void logoutFromFacebook() {
        Session session = Session.getActiveSession();
        session.closeAndClearTokenInformation();
        // Clear Preferences and other data and go back to login activty
    }

从 Google+ 注销。请记住,Google+ 的注销比 Facebook 的注销要复杂一些。单击注销时,您必须管理一个布尔值以跟踪事件(与登录相同)。

public void logoutFromGooglePlus() {
        mGooglePlusLogoutClicked = true;  // Keep track when you click logout
        if (mGoogleApiClient.isConnected()) {
            Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
            revokeAccess();
        } else {
            mGoogleApiClient.connect();   // It can send user to onConnected(), call logout again from there
        }
    }

// revoke access (if needed)
protected void revokeAccess() {

        Plus.AccountApi.revokeAccessAndDisconnect(mGoogleApiClient)
                .setResultCallback(new ResultCallback<Status>() {
                    @Override
                    public void onResult(Status status) {
                        mGoogleApiClient.disconnect();
                        mGoogleApiClient.connect();
                        // Clear data and go to login activity
                    }
                });
    }

要回答评论中的问题: GoogleApiClient可以在应用程序中多次实例化,并且它仍然采用与第一次初始化相同的实例。所以不用担心如何GoogleApiClient在活动之间“传递”。它是一个轻量级客户端,旨在在每个活动中初始化为一个新实例。只需建立一个新的GoogleAPiClient,打电话.connect()并开始工作。但是,您必须实现它所需的接口,但如果您不打算在那里做任何工作,您可以将这些方法留空。

mLogoutClicked布尔值而言,您可以根据需要拥有自己的实现。基本上,这只是一种告诉onConnected()方法您来注销的方法。(看代码,我们也在调用.connect()注销。所以它可能会进入onConnected()并与您的登录代码冲突)。你会在你的onconnected()

public void onConnected(Bundle connectionHint) {

        if (mGooglePlusLogoutClicked) {
            logoutFromGooglePlus();
            mGooglePlusLogoutClicked = false;
        }
    }

作为对您的实施流程的建议,让一个基类完成所有GoogleApiClient初始化,并让登录活动和其他活动对其进行扩展。因此它将隐式处理在每个活动中初始化客户端的问题。只需在基本活动中实现 commononConnected()onConnectionFailed()代码,并让登录活动覆盖这些代码以实现登录逻辑。(对于注销活动也是如此。它将覆盖这些并处理注销代码)
