Adding Search Functionality to LISTVIEW

Adding search functionality to listview will filters the list data with a matching string, hence provides user an easy way to find the information he needs. In this tutorial i am discussing how to enable search filter to android ListView.

1. Create a new project in Eclipse File New ⇒ Android ⇒ Application Project and fill the required details.
2. Create required files needed to generate a listview. I am using my defaultactivity_main.xml as listview and created a new xml file for single listitem namedlist_item.xml. Also make sure that you have created a EditText above the listview which will be used to search the listview.
activity_main.xml

3. Now open your MainActivity.java and paste the following code to create a simple ListView. In the following code i stored all the list data in an array called products[] and attached to listview using simple ArrayAdapter.

Enabling Search Functionality

4. Search functionality can be enabled by writing simple lines of code. All you need to do is adding addTextChangedListener to EditText. Once user enters a new data in EditText we need to get the text from it and passing it to array adapter filter. All the following code in your MainActivity.java

5. Finally add the following property in your AndroidManifest.xml file to hide the keyboard on loading Activity.

android:windowSoftInputMode="stateHidden"
