我已经将应用的主题定义为动态颜色(Material You)。但是每当我在支持Material You的物理设备上运行应用,并且从设置中打开它时,它就不会遵循主题。所有元素都是紫色的,即使在更换墙纸时也是如此。此外,在Dark模式下,它也会显示白色背景和相同的紫色。
在演示功能,我有一个填充色调图标按钮和下拉菜单项containg 5菜单项与4-5字符长的文本。
我在Gruda Linux中使用Android Studio Dolphine。两者都已更新。
我的依赖项版本(& V):

  • build.gradle(项目)
uildscript {
    ext {
        compose_version = '1.3.1'
    }
}// Top-level build file where you can add configuration options common to all sub-projects/modules.

我正在使用材料3与材料你在Jetpack组成和使用图标的材料(谷歌fints)

如果你发现任何错字,请更新它或告诉我修复。
PS:这是我第二次在这里发帖,我对Android开发和Kotlin几乎没有经验。我开发了终端应用程序,用Python,C++,C做了ML工作。所以我可能需要更多的信息来解释。我一周前才开始学习Android开发。
你可以问我更多的信息。
很抱歉很长的职位。我想包括一切加快。
和平🏽

它被自动修复。2天后它突然改变为设备动态颜色。我不知道改变了它,但它不再是问题。所以我关闭这个问题。
