当我尝试将可扩展列表插入现有 Activity (不是从 ExpandalbleListActivity 派生)时，我遇到了几个问题。

该列表确实像我的 XML 布局中描述的那样显示，但是当我尝试单击/展开它时它没有反应。

为了测试，我在列表上方插入了一个按钮，它收到了点击。它自己的列表没有说 clickable=false。

可扩展列表的代码:

<ExpandableListView
android:id="@+id/h_Zzwa_activity_listView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:groupIndicator="@color/transparent" android:clickable="true">
</ExpandableListView>

初始化列表的代码:

this.m_adapter = new HZzwaListAdapter(this, m_requests);
    listZzwa =  (ExpandableListView) findViewById(R.id.h_Zzwa_activity_listView);
    listZzwa.setAdapter(this.m_adapter)

适配器(启动并调用组..)

public class HZzwaListAdapter extends BaseExpandableListAdapter
{

private List<HMyMessage> items;
private Context myContext;


public HZzwaListAdapter(Context context)
{
    myContext = context;
}

public HZzwaListAdapter(Context context, List<HMyMessage> items)
{
    myContext = context;
    this.items = items;
}





@Override
public View getChildView(int groupPosition, int childPosition,
        boolean isLastChild, View convertView, ViewGroup parent)
{

    if (convertView == null)
    {
        LayoutInflater inflater = (LayoutInflater) myContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.h_Zzwa_list_subitem,
                null);
    }

    HMyMessage message = items.get(childPosition);
    if (message != null)
    {
        TextView tvPlayerName = (TextView) convertView
                .findViewById(R.id.h_Zzwalistitem_info_signText);
        tvPlayerName.setText(message.info.getSign());
    }
    return convertView;
}


@Override
public int getChildrenCount(int groupPosition)
{
    return 1;
}


@Override
public Object getGroup(int groupPosition)
{
    return null;
}


@Override
public int getGroupCount()
{
    return items.size();
}


@Override
public long getGroupId(int groupPosition)
{
    return groupPosition;
}


@Override
public View getGroupView(int groupPosition, boolean isExpanded,
        View convertView, ViewGroup parent)
{

    if (convertView == null)
    {
        LayoutInflater inflater = (LayoutInflater) myContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater
                .inflate(R.layout.h_machching_list_item, null);
    }

    // Get item and set it into the view
    HMyMessage plan = (HMyMessage) items.get(groupPosition);
    if (plan != null)
    {
        TextView pname = (TextView) convertView
                .findViewById(R.id.h_Zzwalistitem_pname);
        TextView pF = (TextView) convertView
                .findViewById(R.id.h_Zzwalistitem_pText);

        if (pname != null)
        {
            pname.setText(plan.requester.getName());
        }
        if (pF != null)
        {
            pF.setText(plan.p + " unit  ");
        }
    }

    return convertView;

}


@Override
public boolean hasStableIds()
{
    return false;
}


@Override
public boolean isChildSelectable(int groupPosition, int childPosition)
{
    return true;
}

@Override
public Object getChild(int groupPosition, int childPosition)
{
    // TODO Auto-generated method stub
    return null;
}

@Override
public long getChildId(int groupPosition, int childPosition)
{
    // TODO Auto-generated method stub
    return 0;
}

}

即使我为点击或 listItemClick 事件设置了监听器，也没有任何反应。

为什么？同样的事情对一个普通的列表非常有效:/

谢谢

最佳答案

请添加 child 和组布局。对于 listview，存在一个类似的问题，即 listview 未收到 onItemClick 当 listview 的项目具有按钮时。我之前遇到过这个问题，所以我必须为适配器中的每个项目实现 onclick。检查这个 article ListView doesn’t respond to OnItemClickListener 和 Issue 3414 ListView doesn't receive OnItemClick/OnItemLongClick for items with clickable or focusable content

编辑:为Button View 或EditText View 放置android:focusable="false"。

关于android - ExpandableListView 没有反应并收到任何点击，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10208666/
