如何在“安卓应用(Xamarin)”项目类型中使用RefreshView

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:YourNamespace"
             x:Class="YourNamespace.YourPage">
    <RefreshView x:Name="refreshView" Command="{Binding RefreshCommand}" IsRefreshing="{Binding IsRefreshing}">
        <ScrollView>
            <!-- 在这里添加你的内容 -->
        </ScrollView>
    </RefreshView>
</ContentPage>

public class YourViewModel : INotifyPropertyChanged
{
    public ICommand RefreshCommand { get; private set; }
    public bool IsRefreshing { get; set; }

    public YourViewModel()
    {
        RefreshCommand = new Command(Refresh);
    }

    private void Refresh()
    {
        // 在这里执行刷新操作
        // 可以调用API获取最新数据，更新数据源等

        // 刷新完成后，将IsRefreshing设置为false
        IsRefreshing = false;
    }
}

public YourPage()
{
    InitializeComponent();
    BindingContext = new YourViewModel();
}
