Question

android studio中 listview怎么分组

Answer 1

添加listview"lvwItems"后Edit Column，添加列头

itemView = itemManager.ItemCollection;
从数据源获取数据集合
foreach(Item itm in itemView)
{
ListViewItem lviI = new ListViewItem(itm.ItemName); "%");
itemView = itemManager.ItemCollection;
{
lviI.SubItems.Add(itm.ItemType.ToString());
lviI.SubItems.Add(itm.ItemInput.ToString());
lviI.SubItems.Add(itm.ItemRate.ToString()+
lviI.SubItems.Add(itm.ItemTime.ToString());
lviI.Tag = itm.ItemID;
lvwItems.Items.Add(lviI);
}
遍历数据集合ItemView并获取数据，生成ListViewItem对象Lvil,添加到lvwItems.Items里
(lviI.SubItems.Add(itm.ItemType.ToString());这句就是添加每一列的值，作为subItem)
