答
如果您添加标签为活动，你可以使用这个code选项卡子活动在
If you added the tabs as activities you can use this code inside a tab child activity
TabActivity main = (TabActivity) getParent(); // get the main 'TabActivity' from a Child (tab)
TabHost tabHost = main.getTabHost(); // get a handle to the TabHost
tabHost.setCurrentTab(<index>)
