android-如何从另一个选项卡重新启动选项卡

Question

My application have two tabs: tab1 and tab2 . Initially tab1 is activated. In this tab we have chance to navigate to child activities (In the sense tab1 have initial activity (A1) that consists of one button if you click on that then it will redirects to Activity2 ..).

Now to you tap on the tab2 and it have one button if you click on that then I want to restart the tab1 . It means it shows the tab1 with initial activity (A1). How to implement this. I tried but I am not getting.

Code:

//This will just activate the tab1. it's not reset

CustomTabActivity.mTabHost.setCurrentTab(0)

Answer 1

在onClickListener在TAB2按钮添加以下代码

tabHost.setCurrentTabByTag(String name of Tab1));
