Android 文本样式错误 - 资源不是 ColorStateList

Question

我有一个非常简单的 TextView :

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:textSize="20sp"
android:textColor="@style/basic_text_color"
android:layout_gravity="center"
android:id="@+id/toolbar_title" />

@style/basic_text_color 是一种我想在应用程序中重复使用很多时间的颜色，所以我在 values 文件夹下制作了一个 app_colors.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!--  Text colors style-->
    <style name="basic_text_color" parent="@android:style/TextAppearance">
         <item name="android:textColor">#ff932e</item>
    </style>

    <!-- some other color styles-->
</resources>

应用程序编译成功，但每次执行时都会挂起，并在 LogCat 中提示以下错误:

所以看起来这里的错误是“资源不是 ColorStateList(颜色或路径):TypedValue{t=0x1/d=0x7f0b0124 a=-1 r=0x7f0b0124}”...

我是否以错误的方式设置了字体颜色样式？还是其他什么地方出了问题？谢谢!

颜色.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="basic_text_color">#ff932e</color> 
</resources>

布局

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/app_name"
    android:textSize="20sp"
    android:textColor="@colors/basic_text_color"
    android:layout_gravity="center"
    android:id="@+id/toolbar_title" />

如果您想更改 textColor，您必须创建一个颜色资源文件，因为在您的问题中您正试图将样式设置为颜色。
