在 xaml 中绑定到 C# 代码的 Xamarin ListView

Question

如何将 xaml 文件中带有 ItemTemplate 和 Binding 的以下 ListView 转换为等效的 C# 代码：

<ListView VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" 
    ItemsSource="{Binding A}" ItemSelected="OnClick">
    <ListView.ItemTemplate>
        <DataTemplate>
            <TextCell Text="{Binding b}" Detail="{Binding c}"/>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

Answer 1

尝试这样的事情：

ListView lv = new ListView();
lv.HorizontalOptions = LayoutOptions.FillAndExpand;
lv.VerticalOptions = LayoutOptions.FillAndExpand;
lv.SetBinding(ListView.ItemsSourceProperty, new Binding("A"));
lv.ItemSelected += (sender, args) =>
{
    onclick(sender, args);
}; //Remember to remove this event handler on dispoing of the page;
DataTemplate dt = new DataTemplate(typeof(TextCell));
dt.SetBinding(TextCell.TextProperty, new Binding("b"));
dt.SetBinding(TextCell.DetailProperty, new Binding("c"));
lv.ItemTemplate = dt;

对于更复杂的Datatemplates做：

DataTemplate dt = new DataTemplate(() => 
{
   var button = new Button();
   button.SetBinding(Button.TextProperty, new Binding("Name"));
   return new ViewCell { View = button };
});
