## Setup
### 1. Add Jitpack to your root build.gradle
```gradle
allprojects {
repositories {
maven { url "https://jitpack.io" }
}
}
```
### 2. Add the dependency
```gradle
dependencies {
implementation 'com.github.lriccardo:TimelineView:1.1.2'
}
```
## Usage
### RecyclerView Decorator
```kotlin
recyclerView.addItemDecoration(
TimelineDecorator(
indicatorSize = 24f,
lineWidth = 15f,
padding = 48f,
position = TimelineDecorator.Position.Left,
indicatorColor = Color.RED,
lineColor = Color.RED
)
)
```
- Customization
You can provide a custom drawable for the indicators using `indicatorDrawable` or `indicatorDrawableRes` (`indicatorDrawable` overrides `indicatorDrawableRes`), if both are `null` a circle will be drawn (using the other customization parameters).
If you pass a drawable reference (`indicatorDrawableRes`), `ContextCompat.getDrawable()` will be used internally.

- Advanced customization
If your `RecyclerView.Adapter` implements `TimelineAdapter` you can customize how each item of your list is drawn.
Implementing one or more of these methods, allows you to use the `position` argument to return a different customization for some of your items.
```kotlin
interface TimelineAdapter {
fun getTimelineViewType(position: Int): TimelineView.ViewType?
fun getIndicatorDrawable(position: Int): Drawable?
@DrawableRes fun getIndicatorDrawableRes(position: Int): Int?
fun getIndicatorStyle(position: Int): TimelineView.IndicatorStyle?
fun getIndicatorColor(position: Int): Int?
fun getLineColor(position: Int): Int?
fun getLineStyle(position: Int): TimelineView.LineStyle?
fun getLinePadding(position: Int): Float?
}
```
