Recycler Fast Scroll

Widget for RecyclerView fast scrolling, like Android's built-in fast scroll option for ListView.
Supports any vertically scrolling LayoutManager, as well as proper integration for AppBarLayout.

This is just an updated version of the original project made by Daniel Ciao. It uses new rounded style of material design.

Dependency

Add this to your module's build.gradle file:

repositories {
	//...
	maven { url "https://jitpack.io" }
}
	
dependencies {
	//...
	implementation 'com.github.zixpo:recycler-fast-scroll:{latest-version}'
}

Basic Usage

1. Add the widget to your layout file, e.g.:

   <FrameLayout
       android:layout_width="match_parent"
       android:layout_height="match_parent">
   
       <androidx.recyclerview.widget.RecyclerView
           android:layout_width="match_parent"
           android:layout_height="match_parent" />
   
       <com.pluscubed.recyclerfastscroll.RecyclerFastScroller
           android:layout_width="wrap_content"
           android:layout_height="match_parent"
           android:layout_gravity="end" />
   
   </FrameLayout>

2. Attach the RecyclerFastScroller to your RecyclerView:

   fastScroller.attachRecyclerView(recyclerView);

   If the adapter hasn't been set when you attach the fast scroller, call attachAdapter() afterwords.

See the sample project for demos.

AppBarLayout support

Use attachAppBarLayout(coordinatorLayout, appBarLayout). See the sample project for the demo.

Customization

Method	Attribute	Description
setBarColor(int color)	rfs_barColor	Color of scrollbar. Defaults to colorControlNormal attribute. Alpha of ~22% is applied to the drawable to match stock ListView fast scroller.
setHandleNormalColor(int color)	rfs_handleNormalColor	Color of handle. Defaults to colorControlNormal attribute.
setHandlePressedColor(int color)	rfs_handlePressedColor	Color of pressed handle. Defaults to colorAccent attribute.
setTouchTargetWidth(int width)	rfs_touchTargetWidth	Width of the touch target. Defaults to 24dp (while the Android docs recommend at least 48dp, 24dp is more practical considering it will block touch in the right of the RecyclerView).
setHideDelay(int milliseconds)	rfs_hideDelay	Hide delay in milliseconds. Defaults to 1500ms.
setHidingEnabled(boolean enabled)	rfs_hidingEnabled	Whether scrollbar is hidden after delay. Defaults to true.
setOnHandleTouchListener(OnTouchListener listener)	--	Sets listener for handle touch events.

Corresponding getters are also available.
