【问题描述】:
我有一个场景,例如,在 ListView 中,我有两个标签和每个项目中的自定义水平列表。
水平列表 - 滚动视图中的标签堆栈,方向为水平。
我需要的是,我想引用一个位于 ListView 特定项目的水平列表内的标签,并将水平列表中的选定标签设为粗体。有没有办法引用 ListView 项的控件?
下面是填充我的 ListView 的代码
myListView = new ListView
{
// Source of data items.
ItemsSource = itemsource,
HasUnevenRows = true,
RowHeight = -1,
ItemTemplate = new DataTemplate(() =>
{
Label label1 = new Label()
{
TextColor = Color.Black,
HorizontalTextAlignment = TextAlignment.Start,
FontSize = Device.GetNamedSize(NamedSize.Small, new Label())
};
label1.SetBinding<LVItem>(Label.TextProperty, indexer => indexer.Name);
Label label2 = new Label()
{
TextColor = Color.Black,
HorizontalTextAlignment = TextAlignment.Start,
FontSize = Device.GetNamedSize(NamedSize.Small, new Label())
};
label2.SetBinding<LVItem>(Label.TextProperty, indexer => indexer.SelectedNum);
//horizontal list
StackLayout sLayout = new StackLayout()
{
Orientation = StackOrientation.Horizontal,
};
for (int i = 0; i<itemLst.Count; i++)
{
Label label3 = new Label()
{
HorizontalTextAlignment = TextAlignment.Center,
TextColor = Color.Black,
FontSize = Device.GetNamedSize(NamedSize.Medium, new Label())
};
label3.Text = itemLst[i];
gestureRecognizer = new TapGestureRecognizer
{
Command = new Command(TapL_Tapped),
CommandParameter = label3,
};
label3.GestureRecognizers.Add(gestureRecognizer);
sLayout.Children.Add(label3);
}
ScrollView scroll = new ScrollView
{
Orientation = ScrollOrientation.Horizontal,
Content = new StackLayout
{
Children =
{
sLayout
}
}
};
AbsoluteLayout layout = new AbsoluteLayout();
AbsoluteLayout.SetLayoutFlags(label1, AbsoluteLayoutFlags.All);
AbsoluteLayout.SetLayoutBounds(label1, new Rectangle(0.2, 0.2, 0.8, 0.25));
AbsoluteLayout.SetLayoutFlags(scroll, AbsoluteLayoutFlags.All);
AbsoluteLayout.SetLayoutBounds(scroll, new Rectangle(0.3, 0.6, 0.8, 0.2));
AbsoluteLayout.SetLayoutFlags(label2, AbsoluteLayoutFlags.All);
AbsoluteLayout.SetLayoutBounds(label2, new Rectangle(1.1, 0.3, 0.5, 0.2));
layout.Children.Add(label1);
layout.Children.Add(scroll);
layout.Children.Add(label2);
return new ViewCell
{
View = new StackLayout
{
Children =
{
layout,
}
}
};
}
)};
