Android Studio 3.2.1中的colors.xml版本

以下是笨拙和不完整的 colors.xml 我尝试使用android studio 3.2.1创建一个android项目。

我得到的错误是 D:\AndroidStudioWorkspace\PlayCardz\app\src\main\res\values\colors.xml:7:19: Error: XML document structures must start and end within the same entity.

为什么会这样?

更新

在手动将colors.xml文件更改为following之后,我开始获取以下错误:

Android resource compilation failed
Output:  D:\AndroidStudioWorkspace\GameCardz\app\src\main\res\mipmap-anydpi-v26\ic_launcher_round.xml:1: error: not well-formed (invalid token).

手动更新的colors.xml文件:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!--   color for the app bar and other primary UI elements -->
    <color name="colorPrimary">#3F51B5</color>

    <!--   a darker variant of the primary color, used for
           the status bar (on Android 5.0+) and contextual app bars -->
    <color name="colorPrimaryDark">#303F9F</color>

    <!--   a secondary color for controls like checkboxes and text fields -->
    <color name="colorAccent">#FF4081</color>
</resources>
