Android how do you code now if requery is deprecated?

Question

As per the title, if we used to call cursor.requery(), but it is now deprecated. How do you call this function now?

This method is deprecated. Don't use this. Just request a new cursor, so you can do this asynchronously and update your list view once the new cursor comes back.

So how does one request a new cursor and pass it back to the adapter?

Answer 1

Re-initialize cursor when your any DML query execute.

Answer 2

Just think about a block where you need to use cursor again and again. Populate it with the query. Work with it and then close before reusing

{
    Cursor c =//Populating cursor again
    while (c.moveToNext()) {
    }
    if (c != null) c.close();
}

Answer 3

Use a Loader to manage your cursors. It will return a new Cursor as needed and you can use swapCursor() on the adapter to refresh the data.
