I have a application already working fine. I need to implement a quick search feature to it. Quick search i mean as the users types in every single character i want to result to be fetched. My Activity is a list activity for which the data is coming from the database query. Say the list view has 50 items, and when the user searches with word as "test" I want to query the database and filter the items and display it in the same list view. Something like the contact search in android. Please let me know how to implement this. A quick sample would be help full. Thank you.
