在Xaml中添加StackLayout，其中包含了一个ListView。



:::info{title="右侧写js是因为写成xmal没有代码提醒"}
:::

```js
<StackLayout>
    
    <Label Text="设备列表" 
   HorizontalOptions="Center"
   VerticalOptions="Start" 
       FontSize="Large"/>

    <ListView x:Name="listView" ItemSelected="OnItemSelected" IsPullToRefreshEnabled="true"  RefreshCommand="PullToRefresh"  HasUnevenRows="true" VerticalOptions="Start" HorizontalOptions="FillAndExpand" >
        
        
        <ListView.ItemTemplate>
            <DataTemplate>
                <ViewCell >
                    <StackLayout  Padding="5,5,5,5" BackgroundColor="#000000"  HorizontalOptions="FillAndExpand"  Orientation="Horizontal">
                        <StackLayout  Padding="10,10,10,10" BackgroundColor="#AFEEEE"  HorizontalOptions="FillAndExpand"  Orientation="Horizontal">
                            <StackLayout Padding="5,5,0,0" HorizontalOptions="Start" VerticalOptions="Start" Orientation="Vertical">
                                <Label Text="Name :" VerticalTextAlignment="Center" FontSize="Medium" />
                                <Label Text="Exname :" VerticalTextAlignment="Start" FontSize="Medium" />
                                <Label Text="Classname :" VerticalTextAlignment="Center" FontSize="Medium" />
                                <Label Text="State :" VerticalTextAlignment="Start" FontSize="Medium" />
                                <Label Text="DATATime :" VerticalTextAlignment="Start" FontSize="Medium" />

                            </StackLayout>
                            <StackLayout  Padding="0,5,0,0" HorizontalOptions="Start" VerticalOptions="Start" Orientation="Vertical">
                                <Label Text="{Binding Name}" VerticalTextAlignment="Center" FontSize="Medium" />
                                <Label Text="{Binding Exname}" VerticalTextAlignment="Center" FontSize="Medium" />
                                <Label Text="{Binding Classname}" VerticalTextAlignment="Center" FontSize="Medium" />
                                <Label Text="{Binding State}" VerticalTextAlignment="Center" FontSize="Medium" />
                                <Label Text="{Binding DataTime}" VerticalTextAlignment="Center" FontSize="Medium" />

                            </StackLayout>
                        </StackLayout>
                    </StackLayout>
                </ViewCell>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</StackLayout>

```
添加两个类


```C#
class DriveList
{
    public ObservableCollection<Drivedetel> Driveitemlist { get; set; }
}
public class Drivedetel
{
    public string Name { get; set; }
    public string Exname { get; set; }
    public string DataTime { get; set; }
    public string State { get; set; }
    public string Classname { get; set; }
}
```

DriveMaster

| 红 | 蓝 | 绿 | 黑 | 白 |
| --- | --- | --- | --- | --- |
| 1|  2|3|13|14|


会有雪花，临时使用还行。
