PHP-Fusion Powered Website - Articles: 068 Java Android Program to Demonstrate Search Interface with Suggestion Provider in Android

Here is source code of the Program to Demonstrate Search Interface with Suggestion Provider in Android. The program is successfully compiled and run on a Windows system using Eclipse Ide. The program output is also shown below.

When you’re ready to add search functionality to your application, Android helps you implement the user interface with either a search dialog that appears at the top of the activity window or a search widget that you can insert in your layout. Both the search dialog and the widget can deliver the user’s search query to a specific activity in your application. This way, the user can initiate a search from any activity where the search dialog or widget is available, and the system starts the appropriate activity to perform the search and present results.

Other features available for the search dialog and widget include:
1.Voice search
2.Search suggestions based on recent queries
3.Search suggestions that match actual results in your application data
