ListView in Android
ListView is a view group that displays a list of scrollable items. The list items are automatically inserted to the list using an Adapter that pulls content from a source such as an array or database query and converts each item result into a view that's placed into the list.
Using a CursorLoader is the standard way to query a Cursor as an asynchronous task in order to avoid blocking your app's main thread with the query. When the CursorLoader receives the Cursor result, the LoaderCallbacks receives a callback to onLoadFinished(), which is where you update your Adapter with the new Cursor and the list view then displays the results.
Although the CursorLoader APIs were first introduced in Android 3.0 (API level 11), they are also available in the Support Library so that your app may use them while supporting devices running Android 1.6 or higher.
