TabActivity始终在方向更改时加载第一个标签

Question

A tabactivity has 3 tabs in it. in onCreate() after adding tabs programatically, there is a call to tabHost.setCurrentTab(currentTab);setDefaultTab(currentTab); To display a specific tab. However, This statement has no effect when orientation is changed and onCreate() is called. The tabactivity always shows first tab. How to set a specific tab on orientation change?

Answer 1

Simply call setCurrentTab(x) in onCreate(Bundle savedInstanceState) where x is the last selected tab. When device changes orientation activities are recreated. So when activity is about to be destroyed you have to save its state and restore it when it's recreated. onSaveInstanceState (Bundle outState) is where you save the state. Override this method and put currently selected tab to outState. Then in onCreate (Bundle savedInstanceState) you get currently selected tab from savedInstanceState . Actually outState = savedInstanceState . Basically this how it's done.
