Question

我已经在这个问题上丢失了2天，请提供任何帮助。我有一个Android应用程序，显示2个Android活动图标：“Comp 1”和“Comp 2”。 “Comp 1”和“Comp 2”都显示TabActivities及其中的选项卡。问题：在部署我的应用程序之后，我可以进入“Comp 1”或“Comp 2”TabActivity中的任何一个，但是当我离开活动并且当我尝试输入另一个TabActivity时，显示的选项卡与前一个选项卡相同“ Comp 1“或”Comp 2“它总是取决于我首先开始。目的：对于任何“Comp N”，正确打开TabActivities上指定的选项卡（请参阅本文中的代码）。

请允许我显示我的代码。我将展示AndroidManifest.xml，TabActivity为“Comp 1”，TabActivity为“Comp 2”。它们有点广泛，所以我提前为它们可能包含的任何额外和不必要的信息道歉。我只是不想冒险忘记在第一篇文章中提供任何重要信息。

Answer 1

只有一项活动设定其他人应该设置别的东西，比如然后只有一个活动分配了图标。

Android：多个TabActivities问题
