But when i rotate the screen, values inside the textviews get lost. I know that onSaveInstance state() will. help me to overcome this issues but i don't know how to use it.
can any one help me???
Hope someone will.
Thanks alot in advance.

Answer 1

Override onSaveinstance and put the two string values of textviews into the outstate bundle. Then in onCreate or onRestoreinstance get the strings from the bundle and set them back.
