### Gradle
Add below codes to your **root** `build.gradle` file (not your module build.gradle file).
```gradle
allprojects {
repositories {
jcenter()
}
}
```
And add a dependency code to your **module**'s `build.gradle` file.
```gradle
dependencies {
implementation "com.github.skydoves:expandablelayout:1.0.6"
}
```
## Usage
Add following XML namespace inside your XML layout file.
```gradle
xmlns:app="http://schemas.android.com/apk/res-auto"
```
### ExpandableLayout
Here is a basic example of implementing `ExpandableLayout`.
```gradle
```
### Create using builder class
We can create an instance of `ExpandableLayout` using the builder class.
```kotlin
val myExpandableLayout = expandableLayout(context) {
setParentLayoutResource(R.layout.layout_parent)
setSecondLayoutResource(R.layout.layout_second)
setShowSpinner(true)
setSpinnerAnimate(true)
setSpinnerMargin(12f)
setSpinnerRotation(90)
setDuration(200)
setOnExpandListener { toast("is expanded : $it") }
}
```
### Expand and Collapse
We can expand and collapse using the below methods.
```kotlin
expandablelayout.expand() // expand the second layout with indicator animation.
expandablelayout.collapse() // collapse the second layout with indicator animation.
```
### ParentLayout and SecondLayout
We can get the `parentLayout` and `secondLayout` of the `ExpandableLayout`.
And we can access child views of them.
```kotlin
expandablelayout.parentLayout.setOnClickListener {
toast("the parent layout is clicked!")
}
expandablelayout.secondLayout.setOnClickListener {
toast("the second layout is clicked!")
}
// getting child view using findViewById.
expandablelayout.secondLayout.findViewById
