error: expected color but got (raw string) color/gray

Question

我已经切换到 android studio 3。在我解决了很多问题之后，我得到了这个错误：

color/colorPrimary 但我这样做 error:Error:(87, 5) 错误：预期颜色但得到（原始字符串）color/gray

Answer 1

您忘记在 color/colorPrimary

之前添加 @

改成@color/colorPrimary

示例代码

 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>

    </style>

Answer 2

颜色值应该是 hex 颜色代码，如 #A5D3F4 或带有 @ 符号的颜色参考，如 @color/colorPrimary。在使用这些参考之前，您必须创建像 res/values/color.xml.

这样的资源

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#6200EE</color>
    <color name="colorPrimaryDark">#3700B3</color>
    <color name="colorAccent">#03DAC5</color>
    <color name="LabelColor_text_50">#FFFFFF</color>
    <color name="ValueColor_text_50">#333322</color>
    <color name="LabelColor_bg_50">#A5D3F4</color>
    <color name="ValueColor_bg_50">#E6EEF4</color>
</resources>

并将这些名称用作 <item name="someName">@color/LabelColor_text_50</item>
