我已使用代码将 mtrl_btn_text_color_selector.xml 文件添加到 res/color 文件夹：

【问题讨论】：

你能把你的 XML 代码贴在这里吗？

schemas.android.com/apk/res/android">

【参考方案1】：

您需要更正命名空间。

它应该以 http:// 开头

检查一下：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:alpha="1.00" android:color="?attr/colorPrimary" android:state_checkable="true" android:state_checked="true" android:state_enabled="true" />
    <item android:alpha="0.60" android:color="?attr/colorOnSurface" android:state_checkable="true" android:state_checked="false" android:state_enabled="true" />
    <item android:alpha="1.00" android:color="?attr/colorPrimary" android:state_enabled="true" />
    <item android:alpha="0.38" android:color="?attr/colorOnSurface" />
</selector>

【讨论】：

哦，我的命名空间中确实有 http://，我粘贴代码时一定出了问题

您的代码在我的系统中运行良好。请再检查一次！

另外，你把 XML 放在哪里了？在颜色目录中？

是的，XML 文件在 color 文件夹中。只是不确定我是否有正确的代码，因为我是从 github 获取的
