You can use this adapter when your data source is a database Cursor. When using SimpleCursorAdapter, you must specify a layout to use for each row in the Cursor and which columns in the Cursor should be inserted into which views of the layout.

For example, if you want to create a list of people's names and phone numbers, you can perform a query that returns a Cursor containing a row for each person and columns for the names and numbers. You then create a string array specifying which columns from the Cursor you want in the layout for each result and an integer array specifying the corresponding views that each column should be placed −

String[] fromColumns = {ContactsContract.Data.DISPLAY_NAME,
int[] toViews = {,};

When you instantiate the SimpleCursorAdapter, pass the layout to use for each result, the Cursor containing the results, and these two arrays −

SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
   R.layout.person_name_and_number, cursor, fromColumns, toViews, 0);
ListView listView = getListView();

The SimpleCursorAdapter then creates a view for each row in the Cursor using the provided layout by inserting each from Columns item into the corresponding toViews view.
