如何保持ExpandableListView开的呢？ [英] How to keep the ExpandableListView Opened?

问题描述

我的工作我已经完成的工作，现在只有一个，我想要做的事情是我不希望的ListView是下拉上点击扩展列表视图的，而我想告诉它打开了ExpandableListView所有的项目里面没有显示对他们进行任何点击。

I am working on the ExpandableListView I have completed the work, now only one thing that I want to do is I don't want the ListView to be DropDown on click of the Expandable List View rather I want to show it opened with all the Items displayed inside without performing any click on them.

谁能告诉我，我怎么能做到这一点特别。

Can anyone tell me how can i do that particularly.

推荐答案

做到这一点，每一个群体来展开：

Do this for every one of the groups to expand them:

listView1.expandGroup(int groupPosition);

如果你想prevent组崩溃，那么做到这一点：

If you want to prevent group collapse, then do this:

listView1.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener()
{
    public boolean onGroupClick(ExpandableListView arg0, View itemView, int itemPosition, long itemId)
    {
        listView1.expandGroup(itemPosition);
        return true;
    }
});
