好吧，我不确定发生了什么。我经历了许多这样的“答案”，但没有任何结果。我的列表视图上运行了一个自定义适配器。我希望能够单击列表项以“查看更多”，但我什至无法单击进行注册。

这是我的活动：

我错过了什么？

我想做的是从 XML 中显示标题，然后在列表视图中显示 XML 标题的其他 XML 字段 onClick ...

也许您在 ListView 中的自定义视图具有可点击项目并消耗点击事件？

确保您的 ListView 具有焦点，并且没有其他可以窃取点击事件的可点击项目。

好吧，我不能 100% 确定它为什么现在可以工作，但是，我认为这与回顾我的 XML 并确保根据 Eclipse 没有遗漏任何内容甚至有点偏离有关。

感谢所有的评论。

对于未来的人：检查您的 XML。
