From d021f7a61ae8debee8e2b3ca69a6aee99be41753 Mon Sep 17 00:00:00 2001 From: calderwoodra Date: Tue, 8 Aug 2017 19:04:48 -0700 Subject: Abstracted search cursors in SearchCursor interface This change should help with separating concerns between each module in searchfragment/. Now cursors returned from each CursorLoader are expected to insert their own headers if they want to. This also simplifies the logic in SearchCursorManager and allows for easier implementation of new cursors. Future CLs will include abstracting ViewHolders and CursorLoaders.
