使用Jetpack Compose在Android中使用Circluar ImageView

循环ImageView在许多应用程序中使用。这些类型的图像通常用于表示用户的个人资料图片以及更多其他图像。我们已经看到了使用Jetpack Compose在Android中实现ImageView的实现。在本文中，我们将介绍使用Jetpack Compose在Android中实现Circle ImageView的方法。

分步实施

步骤1：创建一个新项目

要在Android Studio Canary版本中创建新项目，请参阅如何使用Jetpack Compose在Android Studio Canary版本中创建新项目。

步骤2：将图像添加到可绘制的文件夹

创建新项目后，我们必须在可绘制文件夹中添加一个图像，以便在ImageView中显示该图像。从文件夹位置复制图像，然后进入我们的项目。在我们的项目中，导航到应用程序> res> drawable>右键单击drawable文件夹，然后将图像粘贴到该文件夹中。

步骤3：使用MainActivity.kt文件

添加此图像后，导航至应用程序> Java > MainActivity.kt ，并向其添加以下代码。在代码内部添加了注释，以更详细地了解代码。
