如何使用 Jetpack Compose 创建翻转卡片效果
介绍
在电子商务和银行应用程序中输入卡信息是很常见的情况。我认为让用户更轻松地处理这种情况并创建更吸引眼球的 UI 将很有用。大多数应用程序/网站都喜欢它。
执行
在开发阶段，您需要做的是打开一个 Android 项目并实施 Compose 库。
如果我们继续编码，我们可以检查以下 Compose 代码。
您可以根据上面的设计在屏幕上创建您的卡片。
@Composable
fun AddCreditCard(backgroundColor: Color) {
var rotated by remember { mutableStateOf(false) }
val cardType =
when (result.value?.organization) {
"MasterCard" -> painterResource(R.drawable.mc)
"VISA" -> painterResource(R.drawable.visa)
else -> painterResource(R.drawable.ic_launcher_background)
}
val rotation by animateFloatAsState(
targetValue = if (rotated) 180f else 0f,
animationSpec = tween(500)
)
val animateFront by animateFloatAsState(
targetValue = if (!rotated) 1f else 0f,
animationSpec = tween(500)
)
val animateBack by animateFloatAsState(
targetValue = if (rotated) 1f else 0f,
animationSpec = tween(500)
)
Card(
modifier = Modifier
.height(220.dp)
.fillMaxWidth()
.padding(10.dp)
.graphicsLayer {
rotationY = rotation
cameraDistance = 8 * density
}
.clickable {
rotated = !rotated
},
shape = RoundedCornerShape(14.dp),
elevation = 4.dp,
backgroundColor = backgroundColor,
contentColor = Color.White
) {
if (!rotated) {
Column(
horizontalAlignment = Alignment.Start,
verticalArrangement = Arrangement.SpaceBetween,
modifier = Modifier.padding(start = 8.dp, end = 8.dp, bottom = 8.dp),
) {
Row(horizontalArrangement = Arrangement.SpaceBetween) {
Icon(
painter = painterResource(R.drawable.ic_contactless),
contentDescription = "test",
modifier = Modifier
.width(50.dp)
.height(50.dp)
.padding(top = 6.dp, bottom = 6.dp, end = 20.dp)
.graphicsLayer {
alpha = animateFront
},
tint = Color.White
)
Spacer(modifier = Modifier.weight(1f))
Image(
painter = cardType,
contentDescription = "test",
modifier = Modifier
.width(50.dp)
.height(50.dp)
.graphicsLayer {
alpha = animateFront
}
)
}
result.value?.number?.let {
Text(
text = it,
modifier = Modifier
.padding(top = 16.dp)
.graphicsLayer {
alpha = animateFront
},
fontFamily = fontName,
fontWeight = FontWeight.Normal,
fontSize = 25.sp
)
}
Row(horizontalArrangement = Arrangement.SpaceBetween) {
Column(horizontalAlignment = Alignment.Start) {
Text(
text = "Card Holder",
color = Color.Gray,
fontSize = 9.sp,
fontWeight = FontWeight.Bold,
modifier = Modifier
.graphicsLayer {
alpha = animateFront
}
)
Text(
text = "Mehmet Yozgatli",
color = Color.White,
fontSize = 15.sp,
fontWeight = FontWeight.Bold,
modifier = Modifier
.graphicsLayer {
alpha = animateFront
}
)
}
Spacer(modifier = Modifier.weight(1f))
Column(horizontalAlignment = Alignment.Start) {
Text(
text = "VALID THRU",
color = Color.Gray,
fontSize = 9.sp,
fontWeight = FontWeight.Bold,
modifier = Modifier
.graphicsLayer {
alpha = animateFront
}
)
result.value?.expire?.let {
Text(
text = it,
color = Color.White,
fontSize = 15.sp,
fontWeight = FontWeight.Bold,
modifier = Modifier
.graphicsLayer {
alpha = animateFront
}
)
}
}
}
}
} else {
Column(
modifier = Modifier.padding(top = 20.dp),
) {
Divider(
modifier = Modifier
.graphicsLayer {
alpha = animateBack
}, color = Color.Black, thickness = 50.dp
)
Text(
text = "123",
color = Color.Black,
modifier = Modifier
.padding(10.dp)
.background(Color.White)
.fillMaxWidth()
.graphicsLayer {
alpha = animateBack
rotationY = rotation
}
.padding(10.dp),
fontSize = 15.sp,
textAlign = TextAlign.End
)
Text(
text = "Developed by Mehmet Yozgatli",
color = Color.White,
modifier = Modifier
.fillMaxWidth()
.graphicsLayer {
alpha = animateBack
rotationY = rotation
}
.padding(5.dp),
fontFamily = fontName,
fontWeight = FontWeight.Thin,
fontSize = 10.sp,
textAlign = TextAlign.Center
)
}
}
}
}创建卡片后，将旋转、animateFront 和 animateBack 值作为参数传递给组件时，就完成了动画部分。
