如何将一个对象添加到另一个java对象的数组中

我正在开发一个Android应用程序。我的应用程序有一个按钮，当我按下此按钮时，我将解析一个XML文件，将此文件的信息放入某个对象中，并将此对象显示在可扩展列表中。 此外，我的XML文件具有以下结构：

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

我不知道如何将对象片段插入阵列程序，将对象程序插入阵列程序。 我希望你能帮我找到解决这个问题的办法。 多谢各位

• 我个人更喜欢另一种方法，因为它更多的是面向对象的范例，更容易阅读（至少对我来说），更容易应对未来的变化

• 代码如下所示：

• 对象

  程序

  和

  插曲

  被实例化
• 对象

  程序

  和

  插曲

  已填充
• 对象

  节目

  和

  剧集

  将添加到列表中
• 可以使用

  list.get（index）

  从列表中访问对象，并且可以在列表中更改对象，如：

  （（程序）list.get（index））.setDescription（“我的新描述”）

  ，列表将被更新

只是一个问题：在将所有信息插入对象后，我应该执行的最后两条指令是什么？我将插入这个

programsList.add（newprogram（））在我将信息插入到目标程序和这个
programList.add（新插曲（））之后在我将信息插入对象后。是吗？@PaoloRobertetti:你说得很对。首先要做的是将信息插入到剧集中，然后将剧集集合对象插入到节目中，最后将节目对象插入到节目集合中。就这样
