    </ContentPage.BindingContext>
<CollectionView ItemsSource="{Binding Animals}">
        <CollectionView.ItemTemplate>
            <DataTemplate>
                <RadioButton Content="{Binding}" Value="{Binding}"></RadioButton>
            </DataTemplate>
        </CollectionView.ItemTemplate>
    </CollectionView>

Here is QuanxiPageViewModel:

public class QuanxiPageViewModel : ObservableObject
 {
     public QuanxiPageViewModel() {
         GetAnmals();
     }
     ObservableCollection<string> animals;
     public ObservableCollection<string> Animals
     {
         get => animals;
         set => SetProperty(ref animals, value);
     }
     private void GetAnmals()
     {
         animals = new ObservableCollection<string>();
         for (int i = 0; i < 30; i++)
         {
             string a = $"animal No {i}";
             animals.Add(a);
         }
