And? you made 'em based on some data ... send the data not views ... also Do you know that **`onSaveInstanceState` is not for saving persistant data** ? — Selvin, Dec 19 '16 at 15:05
Selvin is also right you can put only the primitive data type in bundle not the views — Amit Thaper, Dec 19 '16 at 15:05

you should not save the view in savedInstanceState. you should only save the value of the listview. it view will be created automatically

I am not saving Views...i want to save a list of Views...each item in the list is a View – Amrmsmb Dec 19 '16 at 15:05
list of views means, view object right.? whatever, you should not do it. Views are heavy weight object. and when activity orientation changes, all views will be destroyed and recreated automatically. – Noorul Dec 19 '16 at 15:08
fine..is it ok to pass a list of Bitmaps? – Amrmsmb Dec 19 '16 at 15:14

yes. but you will face OutOfMemory error. because, each bitmap may have large in size. – Noorul Dec 19 '16 at 15:16
