Question

我已经研究过如何在登录后启动新活动，但每当我尝试实施新活动时，我的应用程序都会崩溃。

我的启动器类登录活动提示通过用户名-pw / Facebook / Google进行身份验证。

现在我正在尝试在onActivityResult方法中启动新活动，但一直在崩溃。尝试了不同的方式来启动它，但现在我迷失了。

我设法在点击按钮后开始一个新片段，或者开始一个新活动，但是登录给我带来了麻烦。

感谢您的帮助 - 非常感谢！

Answer 1

好吧，显然它已经混淆了，因为我最初有2个单独的项目，我合并在一起。第一个活动和以下活动的样式文件中的主题包含有关actionBar的不同信息。另外，我还没有在Manifest中初始化第二个活动。只是一直盯着代码太长时间没注意到这一点。问题解决了:)）
