Android：多个TabActivities问题

Question

我已经在这个问题上浪费了 2 天的时间，请提供任何帮助。 我有一个 Android 应用程序，它显示 2 个 Android 活动图标：“Comp 1”和“Comp 2”。 “Comp 1”和“Comp 2”都显示带有选项卡的 TabActivities。 问题： 部署应用程序后，我可以进入“Comp 1”或“Comp 2”TabActivity 中的任何一个，但是当我离开该活动并尝试输入另一个 TabActivity 时，显示的选项卡与前一个选项卡相同“ Comp 1”或“Comp 2”始终取决于我先开始。 客观的： 对于任何“Comp N”，正确打开 TabActivities 上分配的选项卡（请参阅本文中的代码）。

请允许我展示我的代码。 我将显示 AndroidManifest.xml、“Comp 1”的 TabActivity 和“Comp 2”的 TabActivity。它们有点广泛，因此对于它们可能包含的任何额外和不必要的信息，我提前表示歉意。我只是不想冒险忘记在第一篇文章中提供任何重要信息。

AndroidManifest.xml（“Comp 1”=MMComponentTabAssembler，“Comp 2”=TabAssembler）

Answer 1

只有一项活动设置

其他人应该设置其他东西，例如

然后只有一个活动分配了该图标。
