"content": "RecyclerView Animators\n======================\n
\n \n
\n\n[](https://android-arsenal.com/details/1/1327)\n[](https://www.apache.org/licenses/LICENSE-2.0)\n[](https://search.maven.org/artifact/jp.wasabeef/recyclerview-animators)\n\nRecyclerView Animators is an Android library that allows developers to easily create RecyclerView with animations.\n\nPlease feel free to use this.\n\n# Features\n\n* Animate addition and removal of [`ItemAnimator`](#itemanimator-1)\n* Appearance animations for items in [`RecyclerView.Adapter`](#recyclerviewadapter)\n\n# Demo\n\n### ItemAnimator\n\n\n### Adapters\n\n\n# How do I use it?\n\n## Setup\n\n#### Gradle\n\nOn your module's `build.gradle` file add this implementation statement to the `dependencies` section:\n\n```groovy\ndependencies {\n // Kotlin\n implementation 'jp.wasabeef:recyclerview-animators:4.0.2'\n}\n```\n\nAlso make sure that the `repositories` section includes not only `\"mavenCentral()\"` but also a `maven` section with the `\"google()\"` endpoint. \n\n```\nrepositories {\n google()\n mavenCentral()\n jcenter()\n}\n```\n\n## ItemAnimator\n### Step 1\n\nSet RecyclerView ItemAnimator.\n\n```kotlin\nval recyclerView = findViewById(R.id.list)\nrecyclerView.itemAnimator = SlideInLeftAnimator()\n```\n\n```kotlin\nval recyclerView = findViewById(R.id.list)\nrecyclerView.itemAnimator = SlideInUpAnimator(OvershootInterpolator(1f))\n```\n\n## Step 2\nPlease use the following \n`notifyItemChanged(int)` \n`notifyItemInserted(int)` \n`notifyItemRemoved(int)` \n`notifyItemRangeChanged(int, int)` \n`notifyItemRangeInserted(int, int)` \n`notifyItemRangeRemoved(int, int)` \n\n> If you want your animations to work, do not rely on calling `notifyDataSetChanged()`; \n> as it is the RecyclerView's default behavior, animations are not triggered to start inside this method.\n\n```kotlin\nfun remove(position: Int) {\n dataSet.removeAt(position)\n notifyItemRemoved(position)\n}\n\nfun add(text: String, position: Int) {\n dataSet.add(position, text)\n notifyItemInserted(position)\n}\n```\n\n### Advanced Step 3\n\nYou can change the durations.\n\n```kotlin\nrecyclerView.itemAnimator?.apply {\n addDuration = 1000\n removeDuration = 100\n moveDuration = 1000\n changeDuration = 100\n}\n```\n\n### Advanced Step 4\n\nChange the interpolator.\n\n```kotlin\nrecyclerView.itemAnimator = SlideInLeftAnimator().apply {\n setInterpolator(OvershootInterpolator())\n}\n```\n\n### Advanced Step 5\n\nBy implementing AnimateViewHolder, you can override preset animation.\nSo, custom animation can be set depending on view holder.\n\n```kotlin\nclass MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView), AnimateViewHolder {\n\n override fun preAnimateRemoveImpl(holder: RecyclerView.ViewHolder) {\n // do something\n }\n\n override fun animateRemoveImpl(holder: RecyclerView.ViewHolder, listener: ViewPropertyAnimatorListener) {\n itemView.animate().apply {\n translationY(-itemView.height * 0.3f)\n alpha(0f)\n duration = 300\n setListener(listener)\n }.start()\n }\n\n override fun preAnimateAddImpl(holder: RecyclerView.ViewHolder) {\n itemView.setTranslationY(-itemView.height * 0.3f)\n itemView.setAlpha(0f)\n }\n\n override fun animateAddImpl(holder: RecyclerView.ViewHolder, listener: ViewPropertyAnimatorListener) {\n itemView.animate().apply {\n translationY(0f)\n alpha(1f)\n duration = 300\n setListener(listener)\n }.start()\n }\n}\n```\n\n### Animators\n\n#### Cool\n`LandingAnimator`\n\n##### Scale\n`ScaleInAnimator`, `ScaleInTopAnimator`, `ScaleInBottomAnimator` \n`ScaleInLeftAnimator`, `ScaleInRightAnimator`\n\n\n##### Fade\n`FadeInAnimator`, `FadeInDownAnimator`, `FadeInUpAnimator` \n`FadeInLeftAnimator`, `FadeInRightAnimator`\n\n##### Flip\n`FlipInTopXAnimator`, `FlipInBottomXAnimator` \n`FlipInLeftYAnimator`,

RecyclerView.Adapter\n### Step 1\n\nSet RecyclerView ItemAnimator.\n\n```kotlin\nval recyclerView = findViewById(R.id.list)\nrecyclerView.adapter = AlphaInAnimationAdapter(MyAdapter())\n```\n\n#### Java\n```java\nRecyclerView recyclerView = findViewById(R.id.list);\nrecyclerView.setAdapter(new AlphaInAnimationAdapter(MyAdapter());\n```\n\n### Advanced Step 2\n\n```kotlin\nrecyclerView.adapter = AlphaInAnimationAdapter(MyAdapter()).apply {\n // Change the durations.\n setDuration(1000)\n // Change the interpolator.\n setInterpolator(vershootInterpolator())\n // Disable the first scroll mode.\n setFirstOnly(false)\n}\n```\n\n#### Java\n```java\nAlphaInAnimationAdapter alphaInAnimationAdapter = new AlphaInAnimationAdapter(new MyAdapter());\nalphaInAnimationAdapter.setDuration(1000);\nalphaInAnimationAdapter.setInterpolator(new OvershootInterpolator());\nalphaInAnimationAdapter.setFirstOnly(false);\n```\n\n### Advanced Step 3\n\nMultiple Animations\n\n```kotlin\nval alphaAdapter = AlphaInAnimationAdapter(MyAdapter())\nrecyclerView.adapter = ScaleInAnimationAdapter(alphaAdapter)\n```\n\n#### Java\n```java\nrecyclerView.setAdapter(new ScaleInAnimationAdapter(alphaInAnimationAdapter));\n```\n\n### Adapters\n\n#### Alpha\n`AlphaInAnimationAdapter`\n\n####
