C# listview 控件中，以列表呈现，如何获取选中的某一项的名称

ListView listView1 = new ListView();

listView1Bounds = new Rectangle(new Point(10,10), new Size(300,200));

// Set the view to show details

listView1View = ViewDetails;

// Allow the user to edit item text

listView1LabelEdit = true;

// Allow the user to rearrange columns

listView1AllowColumnReorder = true;

// Display check boxes

listView1CheckBoxes = true;

// Select the item and subitems when selection is made

listView1FullRowSelect = true;

// Display grid lines

listView1GridLines = true;

// Sort the items in the list in ascending order

listView1Sorting = SortOrderAscending;

// Create three items and three sets of subitems for each item

ListViewItem item1 = new ListViewItem("item1",0);

// Place a check mark next to the item

item1Checked = true;

item1SubItemsAdd("1");

item1SubItemsAdd("2");

item1SubItemsAdd("3");

ListViewItem item2 = new ListViewItem("item2",1);

item2SubItemsAdd("4");

item2SubItemsAdd("5");

item2SubItemsAdd("6");

ListViewItem item3 = new ListViewItem("item3",0);

// Place a check mark next to the item

item3Checked = true;

item3SubItemsAdd("7");

item3SubItemsAdd("8");

item3SubItemsAdd("9");

// Create columns for the items and subitems

listView1ColumnsAdd("Item Column", -2, HorizontalAlignmentLeft);

listView1ColumnsAdd("Column 2", -2, HorizontalAlignmentLeft);

listView1ColumnsAdd("Column 3", -2, HorizontalAlignmentLeft);

listView1ColumnsAdd("Column 4", -2, HorizontalAlignmentCenter);

您好：

package comexmythandroid;

public class ListEditorAdapter extends BaseAdapter {

private LayoutInflater mInflater;

private List<Map<String, Object>> mData;// 存储的EditText值

public Map<String, String> editorValue = new HashMap<String, String>();//

public ListEditorAdapter(Context context, List<Map<String, Object>> data) {

mData = data;

mInflater = LayoutInflaterfrom(context);

init();

}

// 初始化

// convertView为null的时候初始化convertView。

if (convertView == null) {

});

public final class ViewHolder {

public TextView title;

public EditText value;// ListView中的输入

public TextView userkey;// 用来定义的标志性主键,可不用关心

}

}

使用ListView的MouseDoubleClick事件，当你选中一行时，会得到ListViewSelectedItem，这个SelectedItem就是ListView数据源集合的一项，这样你就可以想显示什么就显示什么。

比如：ListView的DataContext绑定的数据源是List<Person>,Person类有三个属性（Name，Age，Sex），那么ListViewSelectedItem的值就是Person的一个对象，你想获得Text数据(假设是Name)，只要使用var person = ListViewSelectedItem as Person;personName即可

在ListVIew下面加一个lable 然后剖析ImageList中路径的字符串取得文件名，再将取得的文件名用字符串函数 *** 作，替换或者删除文件名中的数字，将经过剖析和加工后的文件名赋给lable的text属性
