RecyclerView Animators
RecyclerView Animators is an Android library that allows developers to easily create RecyclerView with animations.
Please feel free to use this.
Features
- Animate addition and removal of
ItemAnimator - Appearance animations for items in
RecyclerView.Adapter

Samples
How do I use it?
Setup
Gradle
dependencies {
// jCenter
compile 'jp.wasabeef:recyclerview-animators:2.2.7'
}
ItemAnimator
Step 1
Set RecyclerView ItemAnimator.
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.list);
recyclerView.setItemAnimator(new SlideInLeftAnimator());
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.list);
SlideInUpAnimator animator = new SlideInUpAnimator(new OvershootInterpolator(1f));
recyclerView.setItemAnimator(animator);
Step 2
Please use the following
notifyItemChanged(int)
notifyItemInserted(int)
notifyItemRemoved(int)
notifyItemRangeChanged(int, int)
notifyItemRangeInserted(int, int)
notifyItemRangeRemoved(int, int)
If you want your animations to work, do not rely on calling
notifyDataSetChanged(); as it is the RecyclerView's default behavior, animations are not triggered to start inside this method.
public void remove(int position) {
mDataSet.remove(position);
notifyItemRemoved(position);
}
public void add(String text, int position) {
mDataSet.add(position, text);
notifyItemInserted(position);
}
Advanced Step 3
You can change the durations.
recyclerView.getItemAnimator().setAddDuration(1000);
recyclerView.getItemAnimator().setRemoveDuration(1000);
recyclerView.getItemAnimator().setMoveDuration(1000);
recyclerView.getItemAnimator().setChangeDuration(1000);
Advanced Step 4
Change the interpolator.
SlideInLeftAnimator animator = new SlideInLeftAnimator();
animator.setInterpolator(new OvershootInterpolator());
// or recyclerView.setItemAnimator(new SlideInUpAnimator(new OvershootInterpolator(1f)));
recyclerView.setItemAnimator(animator);
Advanced Step 5
By implementing AnimateViewHolder, you can override preset animation. So, custom animation can be set depending on view holder.
static class MyViewHolder extends RecyclerView.ViewHolder implements AnimateViewHolder {
public MyViewHolder(View itemView) {
super(itemView);
}
@Override
public void preAnimateRemoveImpl(RecyclerView.ViewHolder holder) {
}
@Override
public void animateRemoveImpl(RecyclerView.ViewHolder holder, ViewPropertyAnimatorListener listener) {
ViewCompat.animate(itemView)
.translationY(-itemView.getHeight() * 0.3f)
.alpha(0)
.setDuration(300)
.setListener(listener)
.start();
}
@Override
public void preAnimateAddImpl(RecyclerView.ViewHolder holder) {
ViewCompat.setTranslationY(itemView, -itemView.getHeight() * 0.3f);
ViewCompat.setAlpha(itemView, 0);
}
@Override
public void animateAddImpl(RecyclerView.ViewHolder holder, ViewPropertyAnimatorListener listener) {
ViewCompat.animate(itemView)
.translationY(0)
.alpha(1)
.setDuration(300)
.setListener(listener)
.start();
}
}

RecyclerView.Adapter
Step 1
Set RecyclerView ItemAnimator.
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.list);
MyAdapter adapter = new MyAdapter();
recyclerView.setAdapter(new AlphaInAnimationAdapter(adapter));
Advanced Step 2
Change the durations.
MyAdapter adapter = new MyAdapter();
AlphaInAnimationAdapter alphaAdapter = new AlphaInAnimationAdapter(adapter);
alphaAdapter.setDuration(1000);
recyclerView.setAdapter(alphaAdapter);
Advanced Step 3
Change the interpolator.
MyAdapter adapter = new MyAdapter();
AlphaInAnimationAdapter alphaAdapter = new AlphaInAnimationAdapter(adapter);
alphaAdapter.setInterpolator(new OvershootInterpolator());
recyclerView.setAdapter(alphaAdapter);
Advanced Step 4
Disable the first scroll mode.
MyAdapter adapter = new MyAdapter();
AlphaInAnimationAdapter alphaAdapter = new AlphaInAnimationAdapter(adapter);
scaleAdapter.setFirstOnly(false);
recyclerView.setAdapter(alphaAdapter);
Advanced Step 5
Multiple Animations
MyAdapter adapter = new MyAdapter();
AlphaInAnimationAdapter alphaAdapter = new AlphaInAnimationAdapter(adapter);
recyclerView.setAdapter(new ScaleInAnimationAdapter(alphaAdapter));
