AlphabetIndex Fast Scroll RecyclerView

A Powerful AlphabetIndex FastScroller for Android's RecyclerView!

AlphabetIndex-Fast-Scroll-RecyclerView - Example1 AlphabetIndex-Fast-Scroll-RecyclerView - Example2 AlphabetIndex-Fast-Scroll-RecyclerView - Example3

Kindly use the following links to use this library:

In build.gradle (Project)

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

And then in the other gradle file(may be your app gradle or your own module library gradle, but never add in both of them to avoid conflict.)

dependencies {
    compile 'com.github.myinnos:AlphabetIndex-Fast-Scroll-RecyclerView:1.0.8'
}

How to use

Step 1: add this to your xml:

<in.myinnos.alphabetsindexfastscrollrecycler.IndexFastScrollRecyclerView
    android:id="@+id/fast_scroller_recycler"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Step 2: implement SectionIndexer to RecyclerViewAdapter.

public class RecyclerViewAdapter extends RecyclerView.Adapter<ViewHolder> implements SectionIndexer {

private List<String> mDataArray;
private ArrayList<Integer> mSectionPositions;
    
.....
    
@Override
public int getSectionForPosition(int position) {
    return 0;
}
 
@Override
public Object[] getSections() {
    List<String> sections = new ArrayList<>(26);
    mSectionPositions = new ArrayList<>(26);
    for (int i = 0, size = mDataArray.size(); i < size; i++) {
        String section = String.valueOf(mDataArray.get(i).charAt(0)).toUpperCase();
        if (!sections.contains(section)) {
            sections.add(section);
            mSectionPositions.add(i);
        }
    }
    return sections.toArray(new String[0]);
}
 
@Override
public int getPositionForSection(int sectionIndex) {
    return mSectionPositions.get(sectionIndex);
}
    
}

Note: mDataArray: this is your recycler data array model.
