我的应用程序有一个TabActivity其中包含4个选项卡。每个标签都包含了相应的活动。

My application has a TabActivity which contains 4 tabs. Each tab contains the corresponding activities.

在第一个选项卡中的活动是引导活动。根据某些条件下我必须启用/禁用这项活动的其他3个标签。

可从活动的启用/禁用选项卡中的选项卡里面谁能帮助？

Can anyone help in enabling/disabling tabs from activities inside the tab?

推荐答案

我觉得你是在谈论隐藏选项卡。
然后使用以下

I think you are talking about hiding a tab.
Then use the following

获取 TabHost 从资源作为

TabHost  tabHost = (TabHost)findViewById(android.R.id.tabhost);

然后运行时使用该

tabHost.getTabWidget().getChildAt(3).setVisibility(View.GONE);

假设你正在试图隐藏第四选项卡。（所以3时）

Supposing that you are trying to hide 4th Tab.(So 3 is used)
