Samples

How do I use it?

Setup

Download the latest JAR or grab via Gradle:

Gradle

If you are using a RecyclerView 23.1.0 (released Oct 2015) or higher.

dependencies {
  // jCenter
  compile 'jp.wasabeef:recyclerview-animators:2.0.1'
}

If you are using a RecyclerView 23.0.1 or below.

dependencies {
  // jCenter
  compile 'jp.wasabeef:recyclerview-animators:1.3.0'
}

ItemAnimator

Step 1

Set RecyclerView ItemAnimator.

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.list);
recyclerView.setItemAnimator(new SlideInLeftAnimator());

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.list);
recyclerView.setItemAnimator(new SlideInUpAnimator(new OvershootInterpolator(1f));

Step 2

Please use the notifyItemRemoved and notifyItemInserted.

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

By extending AnimateViewHolder, you can override preset animation.
So, custom animation can be set depending on view holder.

static class MyViewHolder extends AnimateViewHolder {

  public MyViewHolder(View itemView) {
    super(itemView);
  }

  @Override
  public void animateRemoveImpl(ViewPropertyAnimatorListener listener) {
    ViewCompat.animate(itemView)
          .translationY(-itemView.getHeight() * 0.3f)
          .alpha(0)
          .setDuration(300)
          .setListener(listener)
          .start();
  }

  @Override
  public void preAnimateAddImpl() {
    ViewCompat.setTranslationY(itemView, -itemView.getHeight() * 0.3f);
    ViewCompat.setAlpha(itemView, 0);
  }

  @Override
  public void animateAddImpl(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));
