Answer 1

我只能猜到没有看到logcat，但可能你得到的例外是ActivityNotFoundException。在清单中，您的Activities对名称以"android.intent.action"开头的操作做出响应，在代码中，您将启动名称以"com.eric.theworks."开头的操作。我建议你将清单中描述的操作更改为"com.eric.theworks."变体，因为使用默认Android命名进行自定义操作并不是一件好事。希望这能解决你的问题。

Answer 2

最大的可能是其对你们的活动，而不是在清单或布局代码。检查你的logcat日志，并显示崩溃你的应用程序的异常，并会告诉你什么是错误的。
