RecyclerView Animators is an Android library that allows developers to easily create RecyclerView with animations.
Please feel free to use this.
- Animate addition and removal of
ItemAnimator
- Appearance animations for items in
RecyclerView.Adapter
On your module's build.gradle
file add this implementation statement to the dependencies
section:
dependencies {
// Kotlin
implementation 'jp.wasabeef:recyclerview-animators:4.0.2'
}
Also make sure that the repositories
section includes not only "mavenCentral()"
but also a maven
section with the "google()"
endpoint.
repositories {
google()
mavenCentral()
jcenter()
}
Set RecyclerView ItemAnimator.
val recyclerView = findViewById<RecyclerView>(R.id.list)
recyclerView.itemAnimator = SlideInLeftAnimator()
val recyclerView = findViewById<RecyclerView>(R.id.list)
recyclerView.itemAnimator = SlideInUpAnimator(OvershootInterpolator(1f))
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.
fun remove(position: Int) {
dataSet.removeAt(position)
notifyItemRemoved(position)
}
fun add(text: String, position: Int) {
dataSet.add(position, text)
notifyItemInserted(position)
}
You can change the durations.
recyclerView.itemAnimator?.apply {
addDuration = 1000
removeDuration = 100
moveDuration = 1000
changeDuration = 100
}
Change the interpolator.
recyclerView.itemAnimator = SlideInLeftAnimator().apply {
setInterpolator(OvershootInterpolator())
}
By implementing AnimateViewHolder, you can override preset animation. So, custom animation can be set depending on view holder.
class MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView), AnimateViewHolder {
override fun preAnimateRemoveImpl(holder: RecyclerView.ViewHolder) {
// do something
}
override fun animateRemoveImpl(holder: RecyclerView.ViewHolder, listener: ViewPropertyAnimatorListener) {
itemView.animate().apply {
translationY(-itemView.height * 0.3f)
alpha(0f)
duration = 300
setListener(listener)
}.start()
}
override fun preAnimateAddImpl(holder: RecyclerView.ViewHolder) {
itemView.setTranslationY(-itemView.height * 0.3f)
itemView.setAlpha(0f)
}
override fun animateAddImpl(holder: RecyclerView.ViewHolder, listener: ViewPropertyAnimatorListener) {
itemView.animate().apply {
translationY(0f)
alpha(1f)
duration = 300
setListener(listener)
}.start()
}
}

Set RecyclerView ItemAnimator.
val recyclerView = findViewById<RecyclerView>(R.id.list)
recyclerView.adapter = AlphaInAnimationAdapter(MyAdapter())
RecyclerView recyclerView = findViewById(R.id.list);
recyclerView.setAdapter(new AlphaInAnimationAdapter(MyAdapter());
recyclerView.adapter = AlphaInAnimationAdapter(MyAdapter()).apply {
// Change the durations.
setDuration(1000)
// Change the interpolator.
setInterpolator(vershootInterpolator())
// Disable the first scroll mode.
setFirstOnly(false)
}
AlphaInAnimationAdapter alphaInAnimationAdapter = new AlphaInAnimationAdapter(new MyAdapter());
alphaInAnimationAdapter.setDuration(1000);
alphaInAnimationAdapter.setInterpolator(new OvershootInterpolator());
alphaInAnimationAdapter.setFirstOnly(false);
Multiple Animations
val alphaAdapter = AlphaInAnimationAdapter(MyAdapter())
recyclerView.adapter = ScaleInAnimationAdapter(alphaAdapter)
recyclerView.setAdapter(new ScaleInAnimationAdapter(alphaInAnimationAdapter));
