# Tab Animation
[](https://opensource.org/licenses/Apache-2.0)
[](https://search.maven.org/artifact/jp.co.cyberagent.android/tab-animation/)
Easily create `TabLayout.Tab` animations that sync with the scrolling progress of `ViewPager`.
## Features
- Animate Tab when scrolling ViewPager
- Animate Tab after selected/unselected
- Support ViewPager and ViewPager2
- Create animations with DSL
## Demo
|[Tab](sample/src/main/java/jp/co/cyberagent/android/tabanimationsample/TextTabActivity.kt)|[Indicator](sample/src/main/java/jp/co/cyberagent/android/tabanimationsample/IndicatorActivity.kt)|[Bottom Navigation](sample/src/main/java/jp/co/cyberagent/android/tabanimationsample/BottomNavigationActivity.kt)|

## Usage
### Gradle
```gradle
implementation 'jp.co.cyberagent.android:tab-animation:x.y.z'
```
### Step 1
Create animation info for Tab:
```kotlin
val animationInfo = viewIdAnimationInfo {
animateText {
property(View.SCALE_X)
startValue(0.8f)
endValue(1f)
}
animateText {
property(View.SCALE_Y)
startValue(0.8f)
endValue(1f)
}
}
```
### Step 2
Link the TabLayout, ViewPager and animation info:
```kotlin
// TabLayout extension function
tabLayout.setupAnimationTabWithViewPager(
viewPager,
animationInfo,
SimpleTab.TEXT
)
```
## Advanced Usage
### Custom tab view
Provide the layout file id instead of SimpleTab:
```kotlin
tabLayout.setupAnimationTabWithViewPager(
viewPager,
animationInfo,
R.layout.my_custom_tab
) { tab, view, position ->
// bind data here
}
```
### Custom animate target
Specify the target id in viewIdAnimationInfo:
```kotlin
viewIdAnimationInfo {
animate(R.id.my_view) {
...
}
}
```
### Custom property
```kotlin
// Create tint property
animateIcon {
property(
getter = { ImageViewCompat.getImageTintList(this)!! },
setter = { ImageViewCompat.setImageTintList(this, it) }
)
...
}
```
### Custom evaluator
Current support property types:
- Int (ARGB)
- Float
- IntArray
- FloatArray
- PointF
- Rect
- ColorStateList
You must specify the evaluator if the property type you want to animate is not listed:
```kotlin
animate {
evaluator(MyEvaluator)
...
}
```
### Specify KeyFrames
```kotlin
animateText {
property(View.ALPHA)
startValue(0f)
endValue(1f)
keyFrame(0.8f, 0.2f)
}
```
### Lazy value
Animation info will be evaluated after the layout of Tab.
You can calculate the value based on the view:
```kotlin
animateIcon {
property(View.TRANSLATION_X)
startValue { view ->
view.width / 2f
}
endValue { 0f }
}
```
