# DoubleLift
🦋 Expands and collapses a layout horizontally and vertically sequentially.
Inspired by "Viewing Labels" from the Trello.
## Including in your project
[](https://search.maven.org/search?q=g:%22com.github.skydoves%22%20AND%20a:%22doublelift%22)
[](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
// something complicated views or layouts
```
### 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.
```kotlin
LiftAnimation.NORMAL
LiftAnimation.ACCELERATE
LiftAnimation.BOUNCE
```
NORMAL | ACCELERATE | BOUNCE
| :---------------: | :---------------: | :---------------: |
| 
| 
| 
## DoubleLiftLayout Attributes
Attributes | Type | Default | Description
--- | --- | --- | ---
foldedWidth | Dimension | 0 | sets the width size when collapsed.
foldedHeight | Dimension | 0 | ets the height size when collapsed.
horizontalDuration | Long | 500L | sets the duration of horizontal lifting.
verticalDuration | Long | 300L | sets the duration of vertical lifting.
cornerRadius | Dimension | 4dp | sets the corner radius.
autoExpand | Boolean | false | invkoe expand() method initially or not.
startOrientation | LiftStartOrientation | LiftStartOrientation.HORIZONTAL | sets the starting orientation of the lifting.
animation | LiftAnimation | LiftAnimation.NORMAL | sets the lifting animation when expanding and collapsing
