ListView中每一项的高度默认是相同的,除非超过其预定高度值,否则需要动点手脚。
VariableSizedListView 继承 ListView
然后重写
protected override void PrepareContainerForItemOverride(DependencyObject element,
object item)
{
var localItem = item as HeadingItem;
var lvi = element as ListViewItem;
lvi.Height = 28;//这样就修改了高度
lvi.Margin = new Thickness(0, 20, 0, 0);//
}
