我想使用CarouselView創建自動播放幻燈片。這裏是我的代碼: 這是我的XAML頁面:Xamarin CarouselView自動滑塊

,我必將我的[輪播到一個ObservableCollection:
CarouselZoos.ItemsSource = new sliderCarousel().Slides;
namespace DrLink.Controls
{
public class slide
{
public string ImageUrl { get; set; }
public string Name { get; set; }
}
public class sliderCarousel
{
public ObservableCollection<slide> Slides { get; set; }
//public ObservableCollection<Grouping<string, slide>> MonkeysGrouped { get; set; }
//public ObservableCollection<Zoo> Zoos { get; set; }
public sliderCarousel()
{
//Monkeys = MonkeyHelper.Monkeys;
//MonkeysGrouped = MonkeyHelper.MonkeysGrouped;
Slides = new ObservableCollection<slide>
{
new slide
{
ImageUrl = "http://content.screencast.com/users/JamesMontemagno/folders/Jing/media/23c1dd13-333a-459e-9e23-c3784e7cb434/2016-06-02_1049.png",
Name = "Woodland Park Zoo"
},
new slide
{
ImageUrl = "http://content.screencast.com/users/JamesMontemagno/folders/Jing/media/6b60d27e-c1ec-4fe6-bebe-7386d545bb62/2016-06-02_1051.png",
Name = "Cleveland Zoo"
},
new slide
{
ImageUrl = "http://content.screencast.com/users/JamesMontemagno/folders/Jing/media/e8179889-8189-4acb-bac5-812611199a03/2016-06-02_1053.png",
Name = "Phoenix Zoo"
}
};
}
}
}
現在我的問題是:我要自動播放幻燈片,而無需用戶點擊。 2-我想改變動畫類型(從左到右的動畫,從右到左的動畫......),我該怎麼做? 非常感謝
我用Xamarin.Forms.CarouselView沒有XLA輪播畫面。 Xamarin CarouselView不是開源的:https://www.nuget.org/packages/Xamarin.Forms.CarouselView/2.3.0-pre1 –
感謝您的澄清,我不知道這樣的預發佈控制。我必須檢查一下。順便說一句,Xamarin.Forms是開源的,您可以在[GitHub](https://github.com/xamarin/Xamarin.Forms)上找到源代碼。 – hankide
