如何修复“错误：内部元素必须是资源引用或为空”？

Question

今天我决定更新Android Studio，因为我安装的3.1版本似乎有点过时了。升级后，由于某种< code >错误，构建项目失败:

全输出：

错误指向构建文件values.xml，检查它，我想可能问题出在我的arrays.xml文件上。

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="dice_types">
        <item>@string/dice4</item>

我谷歌了一下，发现错误是由这样解析的项目引起的：

<item name="item_1" type="id">Item 1</item>

并且可以通过将代码替换为如下内容来解决:

<item name="item_1" type="id"/>

但是我应该用字符串数组做什么呢？。

听起来您实际上无法将硬编码的值放入项目标记中。将它们放在@strings文件和@integers文件中，然后在项目标记中引用它们？
