# AlphabetIndex Fast Scroll RecyclerView
A Powerful AlphabetIndex FastScroller for Android's RecyclerView!
[](https://jitpack.io/#myinnos/AlphabetIndex-Fast-Scroll-RecyclerView) [](https://www.myinnos.in/) [](https://jitpack.io/#myinnos/AlphabetIndex-Fast-Scroll-RecyclerView) 
#### Kindly use the following links to use this library:
In build.gradle (Project)
```java
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.)
```java
dependencies {
implementation 'com.github.myinnos:AlphabetIndex-Fast-Scroll-RecyclerView:2.0'
// AppCompat version
// implementation 'com.github.myinnos:AlphabetIndex-Fast-Scroll-RecyclerView:1.0.92'
// or
// AndroidX version
// implementation 'com.github.myinnos:AlphabetIndex-Fast-Scroll-RecyclerView:1.0.95'
}
```
How to use
-----
**Step 1:** add this to your xml:
```xml
```
**Step 2:** implement SectionIndexer to RecyclerViewAdapter.
```java
public class RecyclerViewAdapter extends RecyclerView.Adapter implements SectionIndexer {
private List mDataArray;
private ArrayList mSectionPositions;
.....
@Override
public int getSectionForPosition(int position) {
return 0;
}
@Override
public Object[] getSections() {
List 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.
