是choiceMode与ExpandableListView兼容？ [英] Is choiceMode compatible with ExpandableListView?

问题描述

是否有可能做出多重选择列表安卓choiceMode =multipleChoice或 setChoiceMode（ListView.CHOICE_MODE_MULTIPLE）上的 ExpandableListView ？我能够做到这一点与复选框 ES上一个普通的的ListView ，但它似乎并没有与工作 ExpandableListView 。在后者中，单击列表项（父母一方或子女），因为它在前者不影响复选框。

Is it possible to make a multiple choice list with android:choiceMode="multipleChoice" or setChoiceMode(ListView.CHOICE_MODE_MULTIPLE) on an ExpandableListView? I am able to do this with CheckBoxes on a plain ListView, but it doesn't seem to be working with ExpandableListView. In the latter, clicking the list item (either parent or child) does not affect the checkbox as it does in the former.

我已经注意到，有可能准确地点击该复选框，使之切换，但是这是一个非常小的目标。

I have noticed that it is possible to click exactly on the checkbox to make it toggle, but this is a very small target.

推荐答案

一些研究之后，答案是没有。经过的地位似乎是由位置内部跟踪，让家长（又名群）项的​​方式向下已签可能其检查，如果在列表中的previous父膨胀传送到儿童它上面的列表

After some study, the answer is No. "Checked" status seems to be tracked internally by "position", so that a "parent" (aka "group") item a ways down the list that is checked may transfer its check to a child above it if the previous parent in the list is expanded.

我结束了我自己的数据结构跟踪复选标记。

I ended up tracking checkmarks in my own data structure.
