Android、Java、Onclick和；需要Arraylist帮助（我想是吧？）

嘿，伙计们

公正的警告：我对编程非常陌生，更不用说java和android了，所以坦率地说，我甚至不知道如何以正确的方式提出正确的问题。因此，我非常感谢你们中任何一位愿意花时间来研究这一问题并尽可能提供帮助的人！此外，如果你能找到一种方法，把你所有的解决方案都说得哑巴，并像我三岁那样解释它，我也会非常感激。我浏览了developer.android.com，所有的技术术语都让我的困惑变得更糟

所以到目前为止我所做的是

对于一个应用程序，我有以下代码（java和xml），它一旦打开，就会在activity_main.xml文件上显示我的应用程序的三个“类别”（即activities.java文件）。因为这三个都是相同的，所以我在下面发布了MidlandsActivity.java的代码

单击后，它将打开您单击的任何活动类别，并在list_items.xml文件中显示信息的arraylist（如MidlandsActivity.java文件所示）

所以现在。。。我希望能够做到的是：

我希望您能够单击列表中的任何项目（您当前可以单击，但目前它不执行任何操作），然后显示您在新活动中单击的任何列表项目（我想是吧？为了便于交谈，我们将其命名为ListDetails.java，但由于我迷路了，我还没有这样做。或者应该将其编码到MidlandsActivity.java和每个附加的类别活动中吗？）。然后将该活动显示到列表_details.xml文件中，以便全面查看所选类别arraylist中的数据

目前，我确实为此设置了xml文件（list_details.xml），但我不知道下一步需要做什么，也不知道该放在哪里

有什么帮助或建议吗
