您得到的错误是，问题在于名为

Theme.AppCompat.Light.NoActionBar

的主题不包含属性

secondaryColor

。所以，基本上你们要做的就是给不存在的属性赋值

---

根据您的需要，您可以从现有属性中进行选择（获取属性的最简单方法是在

item name=“

”中的空引号内按CTR+SPACE），或者只需添加常规颜色并直接在布局或Java代码中使用它。

您需要在AS 3.0中明确定义项目中的“attr”类型

例如

@color/primaryColor

文件：

另外，不要忘记在attrs.xml中定义属性。 例如

---

在我添加了一个car-lib之后，出现了类似的问题

AAPT: error: style attribute 'attr/listChoiceIndicatorSingleAnimated (aka ****debug:attr/listChoiceIndicatorSingleAnimated)' not found.

缺少的属性在中可用

implementation 'androidx.preference:preference:1.1.1'

---

只需检查缺少属性的库在哪个库中可用，并将其添加为dep.

在Res>Values>Colors.xml中是否有具有该名称的颜色？是的，我有。请检查编辑后的问题我已经添加了实现“com.android.support:design:$android\u support\u version”这个库，它正在工作，在我的例子中$android\u support\u version=28.0.0-alpha3您共享的链接没有关于question@GeekGuy他们删除了迁移指南。。如果您查看url，现在就可以重定向到通用构建页面。我更新了同一页面的archive.org版本的链接。它们键入的标签中有什么确切的值？我仍然有错误。@TheRealChx101您确实将“attr”作为item元素的类型。它指定编译器在attrs.xml文件中查找具有指定名称的attr元素

<item type="attr" name="colorPrimary">@color/primaryColor</item>

<declare-styleable name="Theme">
    <attr name="colorPrimary" format="color|reference" />
</declare-styleable>

AAPT: error: style attribute 'attr/listChoiceIndicatorSingleAnimated (aka ****debug:attr/listChoiceIndicatorSingleAnimated)' not found.

implementation 'androidx.preference:preference:1.1.1'
