How to persist the Dialog Box even after the Screen Orientation Change Android

I have read many articles about serious problem with dialog box that get disappear after screen orientation changes ! Actually the reason for the disappearance , when the screen orientation changes the Android sys. refresh the activity causing restart of activity class! But I have a solution for that hope u enjoy the matter!

Save state concept is used here, with android activity's override methods called

1. Override the onRetainNonConfigurationInstance() method to return the Object you would like to retain.
2. When your Activity is created again, call getLastNonConfigurationInstance() to recover your Object.

thats

public Object onRetainNonConfigurationInstance() {
final MyDataObject data = collectMyLoadedData();
return data;
}       

This following lines should be declared in the on create method to get the state of the activity.  final MyDataObject data = (MyDataObject) getLastNonConfigurationInstance();
if (data == null) {
   data = loadMyData();
} 

I am posting the code Hope U understand more clear......

code having two layout file main.xml contain only one button  and second Layout file name contain two EDITTEXT and one button  http://developer.android.com/guide/topics/resources/runtime-changes.html      this is from where i got the info.... if u want to know more about this issue....
