Android 视图裁剪

Is there any way to define the clip region of a ViewGroup in android (Honeycomb)? For example, I have a ListView with an image background that has rounded corners. As I scroll through the list, the children stick out past the corners of the background - I would prefer them to clip within the rounded corners.

左图是它当前正在做的事情，右图是我想要的事情。

我正在看ClipDrawable，但似乎这可能只能用于进度条？

另外，我正在尝试在小部件中执行此操作。所以我不能使用自定义视图并覆盖 onDraw 进行遮罩。

谢谢你！

确保layout有圆角背景。

Kotlin

layout.outlineProvider = ViewOutlineProvider.BACKGROUND
layout.clipToOutline = true

Java

layout.setOutlineProvider(ViewOutlineProvider.BACKGROUND);
layout.setClipToOutline(true);
