如何在xamarin中使用DisplayPromptAsync方法显示弹出的两个文本框？

string result = await DisplayPromptAsync("标题", "消息", "确定", "取消", "默认文本", -1, Keyboard.Default, "默认值");

using Xamarin.Forms;

public class MyPage : ContentPage
{
    public MyPage()
    {
        Button button = new Button
        {
            Text = "显示弹出框",
            Command = new Command(async () =>
            {
                string result = await DisplayPromptAsync("标题", "消息", "确定", "取消", "默认文本", -1, Keyboard.Default, "默认值");
                if (!string.IsNullOrEmpty(result))
                {
                    // 处理用户输入的文本值
                }
            })
        };

        Content = new StackLayout
        {
            Children = { button }
        };
    }
}
