无法单击其行由WebView组成的ListView [英] Can't click on ListView whose rows are made of WebViews

问题描述

我有一个扩展 ListView 的活动 我使用的ListView是 ArrayAdapter 的扩展，并且ListView的每一行主要由 WebView

I have an Activity which extends ListView The ListView that I use is an extension of ArrayAdapter and each row of the ListView primarily consists of a WebView

问题是触摸WebView不会调用 OnListItemClick .

The problem is that touching the WebView does not call OnListItemClick.

关于如何能够触摸Web视图并调用OnListItemClick的任何想法? 还是我做错了什么? 谢谢！

Any thoughts on how I can be able to touch the webview and call OnListItemClick? Or is there something else that I'm doing wrong? Thanks!

这是Activity类的框架，以及布局的相关XML文件

Here is a skeleton of the Activity class, along with the relevant XML files for the layout

PS，我尝试在布局中设置android:clickable ="false"，但这不能让我单击ListView的行. 有趣的是，我可以仍然滚动列表，但我无法单击！

PS, I've tried setting android:clickable="false" in my layout, but this doesn't let me click on the rows of my ListView. Interestingly, I can still scroll through the list, but I just can't click!

推荐答案

如果将可聚焦元素添加到ListView，则将导致ListView项不再可用.尝试在WebView上设置android:clickable = false.

If you add a focusable element to a ListView, it causes the ListView items to no longer be selectable. Try setting android:clickable = false on your WebView.
