Java 在由片段中的游标适配器填充的ListView中的按钮上设置侦听器

虽然我是一名多年的开发人员，但我对Java/Android和整个OOP都是新手。。。是的，我们仍然存在。。。步履蹒跚的遗物，一个更连续的时代。。。！！ 无论如何，我有一个片段，它调用游标适配器来填充ListView

ListView有几个文本视图，每行有两个按钮

到目前为止，我一直在尝试在每个按钮上设置侦听器，但没有成功。。。 我搜索了这个论坛（和其他论坛），并使用了一些由贡献者推荐的代码

从我的研究来看，我最大的问题似乎是我所做的一切都是从一个片段开始的

我的问题是如何将基本ListView id从片段传递到适配器

我的ListView子XML

好了，伙计们……就这样。。。。希望您能提供帮助

您需要将问题浓缩下来，因为目前还不清楚您在问什么，而只是抛出了一堆代码。请尝试创建一个可复制的最小测试用例，并清楚地陈述您的问题。@AlBlue我知道这个论坛是为所有经验层次的开发人员而设的。我没有足够的参考框架来确保我问的是正确的问题，这导致我“只是转储一堆代码”，以便为“可复制的最小测试用例”提供上下文。“如何将基本ListView id从片段传递到适配器”是否没有明确说明问题？我发现这个论坛的贡献者把他们的时间花在那些人身上，比如我自己，而不会贬低提问者。也许，作为一个在这方面有丰富经验的人，你可以给我一些指导？
