DoubleLift
🦋 Expands and collapses a layout horizontally and vertically sequentially.
Inspired by "Viewing Labels" from the Trello.
Including in your project
Gradle
Add below codes to your root build.gradle file (not your module build.gradle file).
allprojects {
repositories {
mavenCentral()
}
}And add a dependency code to your module's build.gradle file.
dependencies {
implementation "com.github.skydoves:doublelift:1.0.4"
}Usage
Add following XML namespace inside your XML layout file.
xmlns:app="http://schemas.android.com/apk/res-auto"DoubleLiftLayout
Here is a basic example of implementing DoubleLiftLayout.
<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
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
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.
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.
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.
doubleLiftLayout.expand { toast("expanded!") }
doubleLiftLayout.collapse { toast("collapsed!") }OnExpandListener
We can listen to the DoubleLiftLayout is expanded or collapsed.
Java
.setOnExpandListener(new OnExpandListener() {
@Override public void onExpand(boolean isExpanded) {
toast("expanded: " + isExpanded);
}
}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.
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 |
