无法单击带有图像按钮的 ListView 行 [英] Can't click on ListView row with imagebutton

问题描述

我在使用 ListView 时遇到问题.它的项目(行)有一个 ImageButton.ImageButton 设置了 android:onClick，所以这个 onClick 事件有效，但点击行无效.

I have trouble with a ListView. Its items (rows) have an ImageButton. The ImageButton has android:onClick set, so this onClick event is working, but click on row doesn't work.

如果我从行项目中删除 ImageButton，单击行有效(ListView 具有正确的 onClick 侦听器).我该如何解决?当用户点击 ImageButton 时，我需要 onClick 事件，当用户选择行时需要标准的点击事件(不是点击 ImageButton 但单击该行).

If I remove the ImageButton from the row item, click on row works (ListView has correct onClick listener). How can I fix it? I need onClick event when the user clicks on the ImageButton, and the standard click event when the user selects the row (not click the ImageButton but click the row).

我的列表视图:

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/restaurants_list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:divider="@color/list_devider"
        android:dividerHeight="1dp"
        android:cacheColorHint="@color/list_background" /> 

推荐答案

很遗憾，

android:focusable="false"
android:focusableInTouchMode="false"

不适用于 ImageButton.

我终于找到了解决方案这里.在这些项目的布局 xml 中，添加

I finally found the solution here. In your layout xml for those items, add

android:descendantFocusability="blocksDescendants" 

到根视图.

它非常适合具有 ImageButton 的 ListView.根据官方参考，blocksDescendants 意味着 ViewGroup 将阻止其后代接收焦点.

It works perfectly for a ListView that has ImageButtons. According to official reference, blocksDescendants means that the ViewGroup will block its descendants from receiving focus.
