DoubleLift
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 |
