Parameters

constraint
ICharSequence

the constraint with which the query must be filtered

Attributes

Remarks

Runs a query with the specified constraint. This query is requested by the filter attached to this adapter.

The query is provided by a android.widget.FilterQueryProvider. If no provider is specified, the current cursor is not filtered and returned.

After this method returns the resulting cursor is passed to #changeCursor(Cursor) and the previous cursor is closed.

This method is always executed on a background thread, not on the application's main thread (or UI thread.)

Contract: when constraint is null or empty, the original results, prior to any filtering, must be returned.
