How can I animate between 0 and wrap content values using compose
问题
我正在尝试使用Compose制作一个滑动以显示组件，但我希望在滑动后出现的卡片的宽度能够根据内容自动增长，而不使用固定值，但我不明白如何计算包裹内容的大小。
如何将此处使用的宽度值等同于包裹内容的值？
英文:
I'm trying to make a swipe to reveal component using compose, but I want the width of the card that will appear after the swipe to grow to the size of the wrap content without using it, but I don't understand how to calculate the wrap content size.
var width by remember {
mutableStateOf(0.dp)
}
val lowerTransition = updateTransition(transitionState, "lowerCardTransition")
val lowerOffsetTransition by lowerTransition.animateFloat(
label = "lowerCardOffsetTransition",
transitionSpec = { tween(durationMillis = ANIMATION_DURATION) },
targetValueByState = { if (isRevealed) width.value else 0f },
)
How do I equate the width value used here to the wrap content value?
I'm trying to make the resulting delete button appear all without using a constant value

尝试使用AnimatedVisibility。出于演示目的，我使用了OnClick，将其替换为OnSwipe。
@Preview
@Composable
fun AnimateVisibility2() {
var visible by remember {
mutableStateOf(false)
}
Row(
modifier = Modifier.fillMaxSize(), horizontalArrangement = Arrangement.Center
) {
AnimatedVisibility(
visible = visible, enter = expandHorizontally(), exit = shrinkHorizontally()
) {
IconButton(onClick = { /*TODO*/ }) {
Icon(Icons.Default.Phone, contentDescription = null)
}
}
Button(onClick = { visible = !visible }, Modifier.weight(1f)) {
Text("点击我")
}
}
}
英文:
Try using AnimatedVisibility. For demo purpose I used OnClick, replace it with OnSwipe.
@Preview
@Composable
fun AnimateVisibility2() {
var visible by remember {
mutableStateOf(false)
}
Row(
modifier = Modifier.fillMaxSize(), horizontalArrangement = Arrangement.Center
) {
AnimatedVisibility(
visible = visible, enter = expandHorizontally(), exit = shrinkHorizontally()
) {
IconButton(onClick = { /*TODO*/ }) {
Icon(Icons.Default.Phone, contentDescription = null)
}
}
Button(onClick = { visible = !visible }, Modifier.weight(1f)) {
Text("Click Me")
}
}
}
