Question

我是Android开发的新手，希望能为我面临的问题提供一些建议。

我的应用要求我实施Google +登录按钮。

我的进步

我遵循指南并完成了Google +登录按钮的所有必要设置步骤
我可以使用登录按钮并检索个人资料电子邮件

我的问题

点击Google +登录按钮后，选择＆＃34;选择帐户＆＃34;对话框显示，允许用户从多个可能的Gmail帐户中进行选择
当用户单击某个帐户然后单击“确认”按钮时，一切正常
但是，当用户点击对话框中的取消按钮时，对话框会消失并重新出现。即使单击后退按钮，对话框也会消失并重新出现。

这可以防止用户选择其他登录选项。

我想知道我的代码有什么问题，任何帮助都会受到赞赏。感谢。

    super.onCreate(savedInstanceState);

    FacebookSdk.sdkInitialize(getApplicationContext());

            .build();

    SignInButton sign_in_button = (SignInButton) findViewById(R.id.sign_in_button);
    setGooglePlusButtonText(sign_in_button, getString(R.string.google_login_button_label));

        } catch (IntentSender.SendIntentException e) {
            // The intent was canceled before it was sent.  Return to the default
            // state and attempt to connect to get an updated ConnectionResult.
            mIntentInProgress = false;
        }
    }
}


    // google custom button
protected void setGooglePlusButtonText(SignInButton signInButton, String buttonText) {
    for (int i = 0; i < signInButton.getChildCount(); i++) {
        View v = signInButton.getChildAt(i);

        if (v instanceof TextView) {
            TextView tv = (TextView) v;
            tv.setTextSize(15);
            tv.setTypeface(null, Typeface.NORMAL);
            tv.setInputType(InputType.TYPE_TEXT_FLAG_CAP_WORDS);
            tv.setText(buttonText);
            return;
        }
    }
}

Answer 1

在 onActivityResult 方法中检查resultCode。

d_

现在 onConnectionFailed 不会执行 startIntentSenderForResult

Answer 2

我也有同样的问题，用这个解决了

SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
                    SharedPreferences.Editor editor = sp.edit();
                    editor.putString(PREF_ACCOUNT_NAME, "cancel");
                    editor.apply();
                    this.finish();

...谢谢

Answer 3

我遇到了同样的问题。对于＆＃34;取消＆＃34; action，（responseCode！= RESULT_OK）也返回true，所以我在onActivityResult（..）方法中捕获它。这是代码：

 protected void onActivityResult(int requestCode, int responseCode, Intent data) {
    // TODO Auto-generated method stub
    if (requestCode == RC_SIGN_IN) {
        if (responseCode != RESULT_OK) {
                mSignInClicked = false;
        }else if (responseCode == RESULT_OK) {
            if (!mGoogleApiClient.isConnected()) {
                mGoogleApiClient.reconnect();                   
            }           
        }
        mIntentInProgress = false;
    } else {
        ParseFacebookUtils.onActivityResult(requestCode, responseCode,   data);
    }

}

Google+登录按钮无法取消
