答案 0 :(得分：1)
我只能在没有看到logcat的情况下猜测，但可能你得到的例外是ActivityNotFoundException。在您的清单中，您的Activities会回复名称以"android.intent.action"开头的操作，而代码则会启动名称以"com.eric.theworks."开头的操作。我建议您将清单中描述的操作更改为"com.eric.theworks."变体，因为使用自定义操作的默认Android命名不是一件好事。希望这能解决你的问题。

最有可能是您的活动中的代码而不是清单或布局。检查您的logcat日志，并显示崩溃您的应用程序的异常，并为您提供错误信息。
