如何使用 Jetpack Compose 创建翻转卡片效果

使用Jetpack Compose实现翻转卡片效果流程详解

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。

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。
