为什么我的 styles.xml 文件 (Android Studio) 中出现“Android 资源链接失败”

Question

嗨，我在 Android Studio 工作，并尝试为我的启动画面创建一个背景，该背景使用我的“rideshare_splash”图像作为背景，正如我在这个时间戳上一直在关注的教程中一样（ https://youtu.be/144TuYxEu2M ?t=572 ）但是当我 go 构建时，我收到一条错误消息，提示“Android 资源链接失败”。

我在这里查看了类似标题的线程，但最相关的线程建议使用attr 名称而不是因为它已经过时而不起作用，然后我尝试了使用android:colorPrimary的建议，但这也没有帮助所以我想我会尝试问我自己的问题。

styles.xml代码

<?xml version="1.0" encoding="UTF-8"?>
<resources>

    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

错误消息（从构建控制台复制并粘贴）

What went wrong:
Execution failed for task ':app:processDebugResources'.
 A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
    Android resource linking failed

额外的信息

我的想法是本教程使用@color/coolorPrimary（以及colorPrimaryDark和colorAccent）的方式有问题，或者本教程中的某些内容可能已经过时了，因为它已经有几个月的历史了？

Also a side note: when I opened Android Studio there was no styles.xml only colors, strings and themes.xml files so I had to add my own styles.xml file to follow as the tutorial was doing so maybe that has had an effect ?

Answer 1

I think your colors.xml file does not containg these colors(colorPrimary, colorPrimaryDark and colorAccent) You have to define these colors in your color.xml file.
