you Override toString of object that is in your collection and set:

 listView.setTextFilterEnabled(true);

When set to true, the list will filter results as the user types. The List's adapter must support the Filterable interface for this to work. Must be a boolean value, either "true" or "false". This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type. This corresponds to the global attribute resource symbol textFilterEnabled.
