如何将默认 Google+ 按钮设置为 android 应用

How to get default Google+ button to android app

您好,我正在尝试学习 android 中的 Google 登录功能。我按照 expected.I 按照本教程进行操作并正常工作。 http://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/

这里显示的是默认的 Google 登录按钮,而不是 Google+ 红色按钮。

<com.google.android.gms.common.SignInButton
    android:id="@+id/btn_sign_in"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="20dp"/>

问题 我怎样才能得到 Google+ 按钮如下。

您可以在 this Google's sample code 中找到以下内容,从第 67 行到第 78 行

        // [START customize_button]
        // Customize sign-in button. The sign-in button can be displayed in
        // multiple sizes and color schemes. It can also be contextually
        // rendered based on the requested scopes. For example. a red button may
        // be displayed when Google+ scopes are requested, but a white button
        // may be displayed when only basic profile is requested. Try adding the
        // Scopes.PLUS_LOGIN scope to the GoogleSignInOptions to see the
        // difference.
        SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button);
        signInButton.setSize(SignInButton.SIZE_STANDARD);
        signInButton.setScopes(gso.getScopeArray());
        // [END customize_button]

因此,您可以使用以下内容:

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestScopes(new Scope(Scopes.PLUS_LOGIN))                
                .requestEmail()
                .build();

希望对您有所帮助!
