With significant changes to recyclerview and stable jetpack compose being released, this project will no longer be maintained.
Provides fast scroll and section indexer for recycler view. Uses a different mechanism than similar libraries to provide smooth movement of scroller handle when scrolling the list. Can be used with vertical and horizontal RecyclerViews. You can style it or even use a custom layout and animations for your fast scroll handle and bubble.
In your layout file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<com.futuremind.recyclerviewfastscroll.FastScroller
android:id="@+id/fastscroll"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentRight="true"/>
</RelativeLayout>In Activity/Fragment:
recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
fastScroller = (FastScroller) findViewById(R.id.fastscroll);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(adapter);
//has to be called AFTER RecyclerView.setAdapter()
fastScroller.setRecyclerView(recyclerView);In your RecyclerView.Adapter
public class MyAdapter ... implements SectionTitleProvider{
...
@Override
public String getSectionTitle(int position) {
//this String will be shown in a bubble for specified position
return getItem(position).substring(0, 1);
}
}Note: You have to populate your adapter with enough items for the FastScroll to show. I has an auto-hide mechanism in case there is nothing to scroll.
You can use this library with horizontal LayoutManager. To do it use android:orientation="horizontal" attribute:
<com.futuremind.recyclerviewfastscroll.FastScroller
android:id="@+id/fastscroll"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>Styling was introduced in version 0.1.5 with a limited set of styleable attributes. More are on their way.
You can style the attributes in the xml layout:
<com.futuremind.recyclerviewfastscroll.FastScroller
...
app:fastscroll__handleColor="#8f93d1"
app:fastscroll__bubbleColor="#5e64ce"
app:fastscroll__bubbleTextAppearance="@style/StyledScrollerTextAppearance"
/>Or directly in the code:
fastScroller.setBubbleColor(0xffff0000);
fastScroller.setHandleColor(0xffff0000);
fastScroller.setBubbleTextAppearance(R.style.StyledScrollerTextAppearance);See the example code for more info.
You can set custom layouts and animations for your handle and bubble, using:
myViewProvider = new MyScrollerViewProvider();
fastScroller.setViewProvider(myViewProvider);For more information, consult CustomScrollerViewProvider in the example code.
