我正在尝试截取 DialogFragment 中的卡片 View 。当我通过代码截屏时。顶部圆角未显示，但底部圆角显示正确。我在以下问题中看到了这些问题...
Cardview loses its radius when taken a screenshot programmatically
Using PixelCopy to copy a scaled View within a DialogFragment
根据上述问题，我在 Fragment 类中测试了相同的布局和代码。然后圆角正确显示...

最佳答案
在引用的项目中尝试以下方法替换 ViewImage.kt。主要的变化是传入 View 的窗口而不是 Activity。对话框有自己的窗口，不与 Activity 共享窗口。
ViewImage.kt
