How do I use it?

Setup

Download the latest JAR or grab via Gradle:

Gradle

dependencies {
    compile 'jp.wasabeef:recyclerview-animators:1.2.2'
}

ItemAnimator

Step 1

Set RecyclerView ItemAnimator.

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

Advanced Step 2

You can change the durations.

    recyclerView.getItemAnimator().setAddDuration(1000);
    recyclerView.getItemAnimator().setRemoveDuration(1000);
    recyclerView.getItemAnimator().setMoveDuration(1000);
    recyclerView.getItemAnimator().setChangeDuration(1000);

Advanced Step 3

By extending AnimateViewHolder, you can override preset animation.
So, custom animation can be set depeding 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));
