具有可点击子视图的listview项有时无法将click事件传递到该项目的子视图

问题描述

我有一个列表视图，每个项目都有一个可单击的文本视图，当我单击该文本视图时，将其更改为两个按钮，如果我单击该文本视图的外部，则需要整个项目都可以响应单击事件.

I have a list view , each item has a clickable textview, when I click the textview, then change it into two buttons, if I click the outside of the textview I need the whole item can respond to click event.

我仍然有一个工作线程可以从互联网上获取信息，然后更新列表视图.当工作线程通知列表视图的适配器notifydatasetchange时，同时，我单击列表项中的textview，但是发生了奇怪的事情，我单击了textview，但是整个项目都对单击做出了响应.

I still have a worker thread to get something from internet, then update the listview.When a worker thread notify the list view's adapter notifydatasetchange, and at the same time, I click the textview in a item of the list, but strange things happen, I click the textview but the whole item respond to the click.

我知道这是由listview的回收机制引起的.在正常情况下，当notifydataset更改时，listview将放弃之前发布的事件.但是有时候它不会放弃.但是我想知道是否有一些避免这种情况的解决方法?我希望listview的项目可以放弃在notifydatasetchange之前发布的事件.

I know this is caused by listview' recycle mechanism.At the normal sitituation, when notifydatasetchanged, the listview will give up the event posted before. But some times it doesn't give up. But I want to know is there some workround to avoid this? I hope the listview's item can abandon the event that posted before notifydatasetchange.

推荐答案

    <Button
        …
        android:focusable="false"
    />

</RelativeLayout>
