如何：向 Windows 窗体 ListView 控件中添加列
// Set to details view.
listView1.View = View.D
// Add a column with width 20 and left alignment.
listView1.Columns.Add("File type", 20, HorizontalAlignment.Left);使用 Windows 窗体 ListView 控件添加和移除项// Adds a new item with ImageIndex 3
listView1.Items.Add("List item text", 3);// Removes the first item in the list.
listView1.Items.RemoveAt(0);
// Clears all the items.

给主人留下些什么吧！~~
请登录后评论。fragment中添加了button和checkbox这些控件，此时这些子控件会将焦点获取到，所以常常当点击item时变化的是子控件，item本身的点击没有响应。这时候就可以使用descendantFocusability来解决啦，API描述如下：:descendantFocusability该属性是当一个为view获取焦点时，定义viewGroup和其子控件两者之间的关系。属性的值有三种：& & & & beforeDescendants：viewgroup会优先其子类控件而获取到焦点& & & & afterDescendants：viewgroup只有当其子类控件不需要获取焦点时才获取焦点& & & & blocksDescendants：viewgroup会覆盖子类控件而直接获得焦点通常我们用到的是第三种，即在Item布局的根布局加上android:descendantFocusability=”blocksDescendants”的属性。
