我只是使用setScope
完成的 SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button);
signInButton.setSize(SignInButton.SIZE_STANDARD);
signInButton.setScopes(new Scope[]{Plus.SCOPE_PLUS_LOGIN});

因为,您将播放服务更新为8.4.0。您可以通过自定义登录按钮来实现此目的。
在play-services-8.1.0中,谷歌+按钮显示为红色。之后谷歌从8.4.0更新了该逻辑。我建议您为Google+登录创建自定义按钮。

您可以在此Google示例代码中找到以下内容:
// [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();
希望它有所帮助!
