首先看到这个
binder.addStatusChangeListener(status -> System.err.println(binder.isValid()));
<ListView ItemSelected="ListView_ItemSelected" VerticalOptions="Start" ItemsSource="{Binding RelayList}" SeparatorVisibility="Default" SeparatorColor="Gray" HasUnevenRows="True" >
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell >
<Grid BackgroundColor="#E6E6E6" VerticalOptions="End">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="7*"/>
<ColumnDefinition Width="3*"/>
</Grid.ColumnDefinitions>
<StackLayout Orientation="Vertical" Grid.Column="0" Padding="10,10,10,0" VerticalOptions="Start">
<StackLayout Orientation="Horizontal">
<Label Text="{Binding RelayName}" TextColor="Black" FontSize="Small" />
<Label Text="{Binding RelayType}" TextColor="Black" FontSize="Small" />
</StackLayout>
</StackLayout>
<Image Grid.Column="1" Source="nextbtn.png" HorizontalOptions="EndAndExpand" />
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</Frame>
</StackLayout>
