Question

我当前正在使用Libgdx Java框架创建游戏，并且我试图创建一个库存系统，在其中使用Json文件创建表。

我正在使用的JSON文件称为uiskin.json。

当我创建Inventory类的实例（使用uiskin.json文件）时，它会给出异常

没有注册名称为“ default”的com.badlogic.gdx.scenes.scene2d.ui.List $ ListStyle

Inventory类中的错误发生在第28行，该行使用外观文件，该外观文件使用json文件。

这是JSON文件：

这是使用uiskin.json文件的类清单。

库存类的第28行发生异常。

我已修复它。 IDE并未将其读取为JSON文件。我安装了libgdx插件，它检测到JSON文件。

JSON问题：未使用名称：默认
