Force Fast Scroll in All ListView Instances and Always Have a Draggable Scroll Bar
You may have noticed in your everyday usage that scrolling behavior isn’t identical in every Android application. In the majority of cases, developers use the built-in ListView functionality to create these scrollable lists. But even using ListView, the end result isn’t always the same.
Certain sorted scrollable ListView instances feature a draggable scroll bar on the right hand side that allows you to quickly navigate between the different list categories. This draggable scroll bar appears when the developer adds android:fastScrollEnabled=”true” into the XML file for the activity in question. But even though many of us find the function extremely useful, this obviously isn’t always the case in every app.
Luckily, XDA Senior Member hamzahrmalik wrote a simple Xposed module that allows users to enable fast scrolling in every app that uses ListView. Once enabled, this module forces every ListView in every application to use fast scroll, like what you’re used to seeing in the contacts app shown in the screenshot to your right.
Naturally, since this is an Xposed module, you must be rooted and running Xposed Framework. If you are an Xposed user and you’d like to speed up your scrolling in the vast majority of apps with a draggable scroll bar, head over to the module thread and give this a try.
