推荐答案

您可以使用onRetainNonConfigurationInstance（）来解决这个问题。

You can use onRetainNonConfigurationInstance() to solve this issue.

public void onCreate(Bundle savedInstanceState)
{
   ....
   lastTab = (Integer) getLastNonConfigurationInstance();
   .....
   if(lastTab != null)
   {
      tabs.setCurrentTab(lastTab);
   }
}

public Object onRetainNonConfigurationInstance() 
{
   return tabs.getCurrentTab();
}
