不支持的操作异常：无法转换为颜色：类型=0x1

Question

我正在使用api 21在nexus 7中运行我的应用程序。当应用程序从后台打开时它强制关闭（除外）

java.lang.UnsupportedOperationException: Can't convert to color: type=0x1
        at android.content.res.TypedArray.getColor(TypedArray.java:404)

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>

颜色值为

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

我找不出原因。有什么帮助吗？

Answer 1

我遇到了同样的问题，在我检查代码后，我发现我在我的style xml文件中使用了@style/custom来设置android:textColor。然后我只是将@color/custom引用到android:textColor，错误消失了。

并且在安卓API 18、API 23中出现了错误。
