Google+从其他活动中退出

Question

我已经开始使用Google+ APIfor android了,我已经按照本教程创建了一个登录应用程序:

https://developers.google.com/+/mobile/android/sign-in

现在,问题是我想从一个不同的创建注销按钮Activity,我试图做的事情并没有真正起作用..

我的GPlusLogin代码(Google+登录活动):

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.content.IntentSender.SendIntentException;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import com.google.android.gms.common.*;
import com.google.android.gms.common.GooglePlayServicesClient.ConnectionCallbacks;
import com.google.android.gms.common.GooglePlayServicesClient.OnConnectionFailedListener;
import com.google.android.gms.plus.PlusClient;

public class GPlusLogin extends Activity implements ConnectionCallbacks, OnConnectionFailedListener{

    private static final int REQUEST_CODE_RESOLVE_ERR = 9000;
    private static final String TAG = "GPlusLogin";

    private ProgressDialog mConnectionProgressDialog;
    private PlusClient mPlusClient;
    private ConnectionResult mConnectionResult;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gplus_layout);
        mPlusClient = new PlusClient.Builder(this, this, this).setVisibleActivities("http://schemas.google.com/AddActivity", "http://schemas.google.com/BuyActivity").build();
        Bundle extras = getIntent().getExtras();
        mConnectionProgressDialog = new ProgressDialog(this);
        mConnectionProgressDialog.setMessage("Signing in...");

        if(extras!=null){
            if(extras.getString("signout")!=null){
                if (mPlusClient.isConnected()) {
                    mPlusClient.clearDefaultAccount();
                    mPlusClient.disconnect();
                    mPlusClient.connect();
                    finish();
                    startActivity(getIntent());
                }
            }
        }else{

            findViewById(R.id.sign_in_button).setOnClickListener(new OnClickListener() {

                public void onClick(View view) {
                    // TODO Auto-generated method stub
                    if (view.getId() == R.id.sign_in_button && !mPlusClient.isConnected()) {
                        if (mConnectionResult == null) {
                            mConnectionProgressDialog.show();
                        } else {
                            try {
                                mConnectionResult.startResolutionForResult(GPlusLogin.this, REQUEST_CODE_RESOLVE_ERR);
                            } catch (SendIntentException e) {
                                // Try connecting again.
                                mConnectionResult = null;
                                mPlusClient.connect();
                            }
                        }
                    }
                }
            });
        }
    }

    @Override
    protected void onStart() {
        // TODO Auto-generated method stub
        super.onStart();
        mPlusClient.connect();
    }

    @Override
    protected void onStop() {
        // TODO Auto-generated method stub
        super.onStop();
        mPlusClient.disconnect();
    }

    @Override
    public void onConnectionFailed(ConnectionResult result) {
        // TODO Auto-generated method stub
        if (mConnectionProgressDialog.isShowing()) {
            // The user clicked the sign-in button already. Start to resolve
            // connection errors. Wait until onConnected() to dismiss the
            // connection dialog.
            if (result.hasResolution()) {
                try {
                    result.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
                } catch (SendIntentException e) {
                    mPlusClient.connect();
                }
            }
        }

        mConnectionResult = result;
    }

    @Override
    protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
        if (requestCode == REQUEST_CODE_RESOLVE_ERR && responseCode == RESULT_OK) {
            mConnectionResult = null;
            mPlusClient.connect();
        }
    }

    @Override
    public void onConnected() {
        // TODO Auto-generated method stub
        mConnectionProgressDialog.dismiss();
        Intent main = new Intent(GPlusLogin.this, MainActivity.class);
        main.putExtra("result", true);
        startActivity(main);
    }

    @Override
    public void onDisconnected() {
        // TODO Auto-generated method stub
        Log.d(TAG, "disconnected");
    }

}

我的断开代码MainActivity:

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;


public class MainActivity extends Activity{

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Bundle extras = getIntent().getExtras();
        if(extras==null){
            Intent intent = new Intent(this, GPlusLogin.class);
            startActivity(intent);
        }
        TextView text1 = (TextView) findViewById(R.id.text1);
        text1.setText("You Are Connected :D");

        Button SignOut = (Button) findViewById(R.id.sign_out_gplus);
        SignOut.setOnClickListener(new OnClickListener() {

            @Override

                // TODO Auto-generated method stub
                Intent intent = new Intent(MainActivity.this, GPlusLogin.class);
                intent.putExtra("signout", true);
                startActivity(intent);
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

只需在您的新活动中添加此项,您希望google +的注销按钮位于此处:

@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();
}

和下一个:

 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);
                      }
                  });
      }
  });

嘿,我自己解决了这个问题,像魅力一样工作

问题是:Google plus登录一项活动,但需要从其他活动退出

解:

我的Google-plus登出活动是这样的:

public class MainActivity extends Activity implements OnClickListener,
    ConnectionCallbacks, OnConnectionFailedListener,
    ResultCallback<People.LoadPeopleResult> {

   GoogleApiClient mGoogleApiClient;
   boolean mSignInClicked;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this).addApi(Plus.API)
            .addScope(Plus.SCOPE_PLUS_LOGIN).build();

     //copy this code on "Logout" Onclick
  logout.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
             if (mGoogleApiClient.isConnected()) {
            Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
            mGoogleApiClient.disconnect();
            mGoogleApiClient.connect();
            // updateUI(false);
            System.err.println("LOG OUT ^^^^^^^^^^^^^^^^^^^^ SUCESS");
        } 

        }
    });

}
@Override
public void onConnected(Bundle arg0) {
    // TODO Auto-generated method stub
    mSignInClicked = false;

    // updateUI(true);
    Plus.PeopleApi.loadVisible(mGoogleApiClient, null).setResultCallback(
            this);
}

@Override
public void onConnectionSuspended(int arg0) {
    // TODO Auto-generated method stub
    mGoogleApiClient.connect();
    // updateUI(false);
}

@Override
public void onConnectionFailed(ConnectionResult arg0) {
    // TODO Auto-generated method stub

}

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

protected void onStop() {
    super.onStop();
    if (mGoogleApiClient.isConnected()) {
        mGoogleApiClient.disconnect();
    }
}

@Override
public void onResult(LoadPeopleResult arg0) {
    // TODO Auto-generated method stub

}

解决方案说明:

对于单个包,google plus API将生成一个令牌和会话.这里只需在注销页面中再创建一个会话.您可以轻松地从会话中退出

我已经尝试了很多关于这个问题,从当前会话退出,试试这个.它肯定会工作.任何疑惑让我知道

创建基类并继承connect/disconnect方法可能更容易.Photohunt,我们的完整样本,详细记录了这个设计.
