今天給大家推薦一款酷炫的RecyclerView庫(kù)，只要幾句代碼需忿，就可以給RecyclerView的Item添加酷炫的動(dòng)畫(huà)月而。
效果圖

使用方法

1. 添加依賴

dependencies {
  // jCenter
  compile 'jp.wasabeef:recyclerview-animators:2.2.7'
}

2. 添加動(dòng)畫(huà)有兩種方式包晰，第一種是添加ItemAnimator動(dòng)畫(huà)伐憾，第二種請(qǐng)參見(jiàn)第3點(diǎn)
   （1）設(shè)置RecyclerView的ItemAnimator

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

或者

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.list);
SlideInUpAnimator animator = new SlideInUpAnimator(new OvershootInterpolator(1f));  //相比于第一種蒸矛，第二種為SlideInUpAnimator添加插值器
recyclerView.setItemAnimator(animator);

（2）請(qǐng)勿直接使用notifyDataSetChanged()方法
建議采用一下方法取代notifyDataSetChanged()，如果直接使用notifyDataSetChanged()方法，則動(dòng)畫(huà)無(wú)法觸發(fā)

notifyItemChanged(int)
notifyItemInserted(int)
notifyItemRemoved(int)
notifyItemRangeChanged(int, int)
notifyItemRangeInserted(int, int)
notifyItemRangeRemoved(int, int)

（3）設(shè)置動(dòng)畫(huà)時(shí)長(zhǎng)

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

（4）添加插值器

SlideInLeftAnimator animator = new SlideInLeftAnimator();
animator.setInterpolator(new OvershootInterpolator());
// or recyclerView.setItemAnimator(new SlideInUpAnimator(new OvershootInterpolator(1f)));
recyclerView.setItemAnimator(animator);

（5）在ViewHolder實(shí)現(xiàn)AnimateViewHolder接口

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();
  }
}

2. 通過(guò)設(shè)置RecyclerView.Adapter添加動(dòng)畫(huà)
   （1）設(shè)置ItemAnimator

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.list);
MyAdapter adapter = new MyAdapter();
recyclerView.setAdapter(new AlphaInAnimationAdapter(adapter));

（2）設(shè)置動(dòng)畫(huà)時(shí)長(zhǎng)

MyAdapter adapter = new MyAdapter();
AlphaInAnimationAdapter alphaAdapter = new AlphaInAnimationAdapter(adapter);
alphaAdapter.setDuration(1000);
recyclerView.setAdapter(alphaAdapter);

（3）設(shè)置插值器

MyAdapter adapter = new MyAdapter();
AlphaInAnimationAdapter alphaAdapter = new AlphaInAnimationAdapter(adapter);
alphaAdapter.setInterpolator(new OvershootInterpolator());
recyclerView.setAdapter(alphaAdapter);

（4）取消第一次滑動(dòng)模式

MyAdapter adapter = new MyAdapter();
AlphaInAnimationAdapter alphaAdapter = new AlphaInAnimationAdapter(adapter);
scaleAdapter.setFirstOnly(false);
recyclerView.setAdapter(alphaAdapter);

（5）多重動(dòng)畫(huà)（可選）

MyAdapter adapter = new MyAdapter();
AlphaInAnimationAdapter alphaAdapter = new AlphaInAnimationAdapter(adapter);
recyclerView.setAdapter(new ScaleInAnimationAdapter(alphaAdapter));
