A Powerful AlphabetIndex FastScroller for Android's RecyclerView!
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 {
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'
}
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);
}
}
mRecyclerView.setIndexTextSize(12);
Change IndexBarTextColor:
mRecyclerView.setIndexBarTextColor("#FFFFFF");
mRecyclerView.setIndexBarTextColor(R.color.index_bar_text_color);
Change IndexBarColor:
mRecyclerView.setIndexBarColor("#33334c");
mRecyclerView.setIndexBarColor(R.color.index_bar_color);
mRecyclerView.setIndexBarCornerRadius(3);
mRecyclerView.setIndexBarTransparentValue((float) 0.4);
mRecyclerView.setIndexBarMargin(4);
mRecyclerView.setIndexBarWidth(40);
mRecyclerView.setPreviewPadding(2);
mRecyclerView.setPreviewVisibility(false);
Typeface typeface = Typeface.createFromAsset(context.getAssets(), "Custom-Font.ttf");
mRecyclerView.setTypeface(typeface);
mRecyclerView.setIndexBarVisibility(true);
mRecyclerView.setIndexBarHighLightTextColor("#33334c);
mRecyclerView.setIndexBarHighLightTextColor(R.color.index_bar_highlight_text_color);
- To hide/show IndexBarHighLightText:
```java
mRecyclerView.setIndexBarHighLightTextVisibility(true);
mRecyclerView.setIndexBarStrokeVisibility(true);
mRecyclerView.setIndexBarStrokeWidth(1);
mRecyclerView.setIndexBarStrokeColor("#000000");
This library works with any layout manager but is optimized for the use with a LinearLayoutManager.
