android - Android 上的 Google+ 登录按钮在点击时没有任何反应

Question

我正在尝试在我的 Android 应用程序中实现 Google+ 登录。我遵循了 Google+ API 教程。但是，当我单击登录按钮时，没有任何反应，没有出现登录对话框或提示。 Logcat 也没有显示任何错误。当我遵循 Google+ API 文档时，我似乎无法理解为什么这不起作用。

这是我的代码:

        edit.commit();

在 mGoogleApiClient 试试这个

   mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApiIfAvailable(Drive.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this).addApi(Plus.API, Plus.PlusOptions.builder().build())
            .addScope(Plus.SCOPE_PLUS_LOGIN).build();
