## Including in your project
[![Maven Central](https://img.shields.io/maven-central/v/com.github.skydoves/doublelift.svg?label=Maven%20Central)](https://search.maven.org/search?q=g:%22com.github.skydoves%22%20AND%20a:%22doublelift%22)
[![Jitpack](https://jitpack.io/v/skydoves/DoubleLift.svg)](https://jitpack.io/#skydoves/DoubleLift)
### Gradle 
Add below codes to your **root** `build.gradle` file (not your module build.gradle file).
```gradle
allprojects {
    repositories {
        mavenCentral()
    }
}
```
And add a dependency code to your **module**'s `build.gradle` file.
```gradle
dependencies {
    implementation "com.github.skydoves:doublelift:1.0.4"
}
```

## Usage
Add following XML namespace inside your XML layout file.

```gradle
xmlns:app="http://schemas.android.com/apk/res-auto"
```

### DoubleLiftLayout
Here is a basic example of implementing `DoubleLiftLayout`.

```gradle
<com.skydoves.doublelift.DoubleLiftLayout
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  app:doubleLift_foldedWidth="50dp" // sets the width size when collapsed.
  app:doubleLift_foldedHeight="10dp" // sets the height size when collapsed.
  app:doubleLift_horizontalDuration="400" // sets the duration of horizontal lifting.
  app:doubleLift_verticalDuration="300" // sets the duration of vertical lifting.
  app:doubleLift_cornerRadius="4dp" // sets the corner radius.
  app:doubleLift_autoExpand="false" // expand initially or not.
  app:doubleLift_startOrientation="horizontal"
  app:doubleLift_animation="bounce" // sets the lifting animation when expanding and collapsing
  >

  <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="Feature"
    android:textColor="@color/white_87"
    android:textStyle="bold" />
    
  // something complicated views or layouts
  
</com.skydoves.doublelift.DoubleLiftLayout>
```

### Create using builder class
We can create an instance of `DoubleLiftLayout` using the `DoubleLiftLayout.Builder` class.
#### Java
```java
DoubleLiftLayout doubleLiftLayout = new DoubleLiftLayout.Builder(context)
    .setFoldedWidth(200)
    .setFoldedHeight(100)
    .setCornerRadius(6)
    .setLiftHorizontalDuration(400)
    .setLiftVerticalDuration(200)
    .setOnExpandListener(new OnExpandListener() {
      @Override public void onExpand(boolean isExpanded) {
        toast("expanded: " + isExpanded);
      }
    }).build();
```

#### Kotlin
```kotlin
val myDoubleLiftLayout = DoubleLiftLayout.Builder(context)
  .setFoldedWidth(200)
  .setFoldedHeight(100)
  .setCornerRadius(6)
  .setLiftHorizontalDuration(400)
  .setLiftVerticalDuration(200)
  .setOnExpandListener { toast("expanded: $it") }
  .build()
```
Or we can create using the kotlin-dsl.
```kotlin
val myDoubleLiftLayout = doubleLiftLayout(this) {
  setFoldedWidth(200)
  setFoldedHeight(100)
  setCornerRadius(6)
  setLiftHorizontalDuration(400)
  setLiftVerticalDuration(200)
  setOnExpandListener { toast("expanded: $it") }
}
```

### Expand and Collapse
We can expand and collapse using the below methods.
```kotlin
doubleLiftLayout.expand(); // expand the width and height size sequentially.
doubleLiftLayout.collapse(); // collapse the width and height size sequentially.
```

or we can do something after expanded using lambda in Kotlin.

```kotlin
doubleLiftLayout.expand { toast("expanded!") }
doubleLiftLayout.collapse { toast("collapsed!") }
```

### OnExpandListener
We can listen to the `DoubleLiftLayout` is expanded or collapsed.
#### Java
```java
.setOnExpandListener(new OnExpandListener() {
  @Override public void onExpand(boolean isExpanded) {
    toast("expanded: " + isExpanded);
  }
}
```
#### Kotlin
```kotlin
doubleLiftLayout.onExpandListener = object : OnExpandListener {
  override fun onExpand(isExpanded: Boolean) {
    toast("Expanded : $it")
  }
}

// or we can listen using a lambda expression.
doubleLiftLayout.setOnExpandListener {
  if (it) {
    toast("expanded")
  } else {
    toast("collapse")
  }
}
```

### LiftAnimation
We can customize the expanding and collapsing animation.<br>
```kotlin
LiftAnimation.NORMAL
LiftAnimation.ACCELERATE
LiftAnimation.BOUNCE
```

NORMAL | ACCELERATE | BOUNCE
| :---------------: | :---------------: | :---------------: |
