我正在为应用程序使用主题 AppTheme。

<style name="AppTheme" parent="AppTheme.Base" />

<style name="AppTheme.Base" parent="Theme.AppCompat">
    <item name="colorPrimary">@color/theme_color</item>
    <item name="colorPrimaryDark">@color/theme_color_dark</item>
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@android:color/white</item>
</style>

颜色值是

<color name="theme_color">#b61702</color>
<color name="theme_color_dark">#a70001</color>

我找不到原因。有什么帮助吗？

Answer 1

我遇到了同样的问题，在检查我的代码后，我发现我使用 @style/custom 在我的样式 xml 文件中设置了 android:textColor。然后我只是将@color/custom 引用到android:textColor，错误消失了。

Android API 18 发生错误，API 23 运行良好。
