无法单击带有图像按钮的 ListView 行

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.
