How to enable fast scrolling in Android

Fast Scrolling in Android happens when you have a lot of items in your screen and you need to scroll fast. When it is activated you well see an small box coming from the right of the screen and when you drag it up or down it goes really fast. You can see this in your contact list, email or any application that has a lot of data and is sorted alphabetically.

There are 2 ways to enable this functionality in your application:
By adding the property in your XML layout file:



    <ListView
        android:id="@id/android:list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:fastScrollEnabled="true" />

or by adding it in your java code:

      getListView().setFastScrollEnabled(true);
