How to show SQLite Multiple data inside EditText one by one using Next Previous buttons.

In my previous tutorial we have talked about creating SQLite database and inserting values directly into database using EditText. Now in this tutorial we are going to do the same work but there is only one difference that we are going to display SQLite database data directly into EditText. So for my further coming tutorials we can edit that data directly form EditText. But for now in this tutorial we are only going to Get Retrieve Multiple data from SQLite database in android and Display inside EditText.

How to Get Retrieve Multiple data from SQLite database in android and Display inside EditText.
