為什么我的 styles.xml 文件 (Android Studio) 中出現“Android 資源鏈接失敗”

Question

嗨，我在 Android Studio 工作，並嘗試為我的啟動畫面創建一個背景，該背景使用我的“rideshare_splash”圖像作為背景，正如我在這個時間戳上一直在關注的教程中一樣（ https://youtu.be/144TuYxEu2M ?t=572 ）但是當我 go 構建時，我收到一條錯誤消息，提示“Android 資源鏈接失敗”。

我在這里查看了類似標題的線程，但最相關的線程建議使用attr 名稱而不是因為它已經過時而不起作用，然后我嘗試了使用android:colorPrimary的建議，但這也沒有幫助所以我想我會嘗試問我自己的問題。

styles.xml代碼

<?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>

錯誤消息（從構建控制台復制並粘貼）

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

額外的信息

我的想法是本教程使用@color/coolorPrimary（以及colorPrimaryDark和colorAccent）的方式有問題，或者本教程中的某些內容可能已經過時了，因為它已經有幾個月的歷史了？

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.
