从活动设置制表 [英] Set a Tab from an activity

问题描述

我有一个TabActivity和内5片5活动各一个。我想设置我的标签之一，但不是从TabActivity（点击顶部的选项卡上），但任何标签的活动，例如点击活动3（这是asociated与第三个标签）的按钮。
在我的TabActivity有一个变量 mTab​​host ，我可以用它来设定

I have a TabActivity and inside 5 tabs with 5 activities each one. I want to set one of my tabs but not from the TabActivity(clicking on the tab on the top) but from an activity of any tab, for example clicking on a button of activity 3(which is asociated with the 3rd tab). In my TabActivity there is a variable mTabhost, which I can use to set the selected tab with

mTabHost.setCurrentTab(0);//home

我想我需要访问来自Activity1-2-3-4的变量，这样做静态变量行不通的。

I guess I need access to that variable from Activity1-2-3-4, and doing that variable static doesnt work.

推荐答案

假设你有一个 MyTabActivity 为 TabActivity ，它承载5 活动（IES）。
如果你想改变里面的 SecondActivity 的标签，你会写code这样的事情。

Say you have a MyTabActivity as TabActivity, which hosts 5 Activity(ies). If you want to change the Tabs inside SecondActivity, you would write the code something like this.

MyTabActivity myTabs = (MyTabActivity) this.getParent();

在这里，你有你的MyTabActvity
您可以更改标签，如：

Here you have your MyTabActvity you can change the tabs like:

myTabs.getTabHost().setCurrentTab(index);
