Jetpack Compose Animation Series

Welcome to my 10 Days of Jetpack Compose Animations! 🎉 In this series, I explore various animations using Jetpack Compose, showcasing creative ways to enhance UI/UX in Android applications.

Day-by-Day Breakdown

Day 1: Thread Card Animation

Simple Roatating Card composable..

 Card(
        modifier = modifier
            .graphicsLayer {
                rotationY = positionAxisY // Move card according to value of customY.
                cameraDistance = 14f * density
            },
    ) {

        // Here, logic is about coordinate system such as [0..90], [91..270], [270..360].
        if (abs(positionAxisY.toInt()) % 360 <= 90) {
            Box(
                Modifier.fillMaxSize()
            ) {
                frontSide()
            }
        } else if (abs(positionAxisY.toInt()) % 360 in 91..270) {
            Box(
                Modifier
                    .fillMaxSize()
                    .graphicsLayer {
                        rotationY = 180f // Important to avoid mirror effect.
                    },
            )
}

Day 2: Game Pad Animation

SimpleGame Pad composable.

 Position.values().forEach { position ->
                    val offset = position.getOffset(buttonSizePx)
                    MyButton(
                        modifier = Modifier
                            .offset {
                                IntOffset(
                                    x = offset.x.roundToInt(),
                                    y = offset.y.roundToInt()
                                )
                            }
                            .graphicsLayer {
                                alpha = buttonAlpha.value
                                scaleX = buttonAlpha.value
                                scaleY = buttonAlpha.value
                            }
                            .size(buttonSize)
                            .padding(8.dp)
                        ,
                        isSelected = position == currentPosition,
                        position = position
                    )
                }

            }

Day 3: Story Animation

Simple Story composable.

@Composable
fun rememberSharedAnimatableState(
    animatableStates: List<AnimatableState>,
    toTargetAnimationsSpec: AnimationSpec<Float>? = null,
    toInitialAnimationsSpec: AnimationSpec<Float>? = null
): SharedAnimatableState {
    return remember {
        SharedAnimatableState(
            animatableStates = animatableStates,
            toTargetAnimationsSpec = toTargetAnimationsSpec,
            toInitialAnimationsSpec = toInitialAnimationsSpec
        )
    }
}

Day 4: Wave Animation

Water Wave composable.

 val wavesShader by produceState<Shader?>(
            initialValue = null,
            constraintsHeight,
            constraintsWidth,
            color,
            density
        ) {
            value = withContext(Dispatchers.Default) {
                createWavesShader(
                    width = with(density) { constraintsWidth.roundToPx() },
                    height = with(density) { constraintsHeight.roundToPx() },
                    color = color
                )
            }
        }
