Orbitary
Download
Gradle
Add the dependency below to your module's build.gradle file:
dependencies {
implementation "com.github.skydoves:orbitary:0.1.0"
}
Note: This is an experimental library that demonstrates various animations with Jetpack Compose. Please make sure that your project uses Jetpack Compose
1.3.0-alpha01, Compose Compiler1.2.0, and Kotlin1.7.0.
Usage
You can implement three kinds of animations with Orbitary: Movement, Transformation, and Shared Element Transition. Basically, you can run animation with Orbitary Composable function, which provides OrbitaryScope that allows you to create animations.
Transformation
The example below shows how to implement resizing animation with the animateTransformation extension of the OrbitaryScope. The rememberContentWithOrbitaryScope allows you to create custom animations such as animateTransformation on the OrbitaryScope. You can apply the animateTransformation animation to specific Composables and customize its AnimationSpec as seen the below:
val transformationSpec = SpringSpec<IntSize>(
dampingRatio = Spring.DampingRatioMediumBouncy,
stiffness = 200f
)
var isTransformed by rememberSaveable { mutableStateOf(false) }
val poster = rememberContentWithOrbitaryScope {
GlideImage(
modifier = if (isTransformed) {
Modifier.size(300.dp, 620.dp)
} else {
Modifier.size(100.dp, 220.dp)
}.animateTransformation(this, transformationSpec),
imageModel = ItemUtils.urls[0],
contentScale = ContentScale.Fit
)
}
Orbitary(
modifier = Modifier
.clickable { isTransformed = !isTransformed }
) {
Column(
Modifier.fillMaxSize(),
horizontalAlignment = Alignment.CenterHorizontally,
verticalArrangement = Arrangement.Center
) {
poster()
}
}
Movement
The example below shows how to implement movement animation with the animateMovement extension of the OrbitaryScope. The rememberContentWithOrbitaryScope allows you to create custom animations such as animateMovement on the OrbitaryScope. You can apply the animateMovement animation to specific Composables and customize its AnimationSpec as seen the below:
val movementSpec = SpringSpec<IntOffset>(
dampingRatio = Spring.DampingRatioMediumBouncy,
stiffness = 200f
)
var isTransformed by rememberSaveable { mutableStateOf(false) }
val poster = rememberContentWithOrbitaryScope {
GlideImage(
modifier = if (isTransformed) {
Modifier.size(360.dp, 620.dp)
} else {
Modifier.size(130.dp, 220.dp)
}.animateMovement(this, movementSpec),
imageModel = ItemUtils.urls[3],
contentScale = ContentScale.Fit
)
}
Orbitary(
modifier = Modifier
.clickable { isTransformed = !isTransformed }
) {
if (isTransformed) {
Column(
Modifier.fillMaxSize(),
horizontalAlignment = Alignment.CenterHorizontally,
verticalArrangement = Arrangement.Center
) {
poster()
}
} else {
Column(
Modifier
.fillMaxSize()
.padding(20.dp),
horizontalAlignment = Alignment.End,
verticalArrangement = Arrangement.Bottom
) {
poster()
}
}
}
Shared Element Transition
The example below shows how to implement shared element transition with the animateSharedElementTransition extension of the OrbitaryScope. The rememberContentWithOrbitaryScope allows you to create custom animations such as animateSharedElementTransition on the OrbitaryScope. You can apply the animateSharedElementTransition animation to specific Composables and customize its AnimationSpec. Also, you can set the different AnimationSpecs for the movement and transformation as seen the below:
var isTransformed by rememberSaveable { mutableStateOf(false) }
val items = rememberContentWithOrbitaryScope {
ItemUtils.urls.forEach { url ->
GlideImage(
modifier = if (isTransformed) {
Modifier.size(140.dp, 180.dp)
} else {
Modifier.size(100.dp, 220.dp)
}
.animateSharedElementTransition(this, movementSpec, transformationSpec)
.padding(8.dp),
imageModel = url,
contentScale = ContentScale.Fit
)
}
}
Orbitary(
modifier = Modifier
.fillMaxSize()
.clickable { isTransformed = !isTransformed },
isTransformed = isTransformed,
onStartContent = {
Column(
Modifier.fillMaxSize(),
horizontalAlignment = Alignment.CenterHorizontally,
verticalArrangement = Arrangement.Center
) {
items()
}
},
onTransformedContent = {
Row(
verticalAlignment = Alignment.CenterVertically
) { items() }
}
)
