壁画从文件播放GIF

Question

I'm using this code to show just a simple image from file. But how can i play gif?

var CatalogMain = System.IO.Path.Combine(Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryPictures).ToString(), "NewFolder");

SimpleDraweeView MainImage = FindViewById<SimpleDraweeView>(Resource.Id.MainImageView);
Android.Net.Uri imageUri = Android.Net.Uri.FromFile(new Java.IO.File(CatalogMain, "Main.gif"));// For files on device
MainImage.SetImageURI(imageUri);

I also found this code, but i'm taking several errors. I dont know how i need to convert it for playing with xamarin.

Uri uri;
DraweeController controller = Fresco.NewDraweeControllerBuilder()
                                    .SetUri(imageUri)
                                    .setAutoPlayAnimations(true)
                                    .build();
mSimpleDraweeView.setController(controller);

I'm getting following errors

Error CS0246 The type or namespace name 'DraweeController' could not be found.

Error CS0103 The name 'mSimpleDraweeView' does not exist in the current.

Error CS1061 'ISimpleDraweeControllerBuilder' does not contain a definition.

You can use this:

Uri uri = Uri.Parse("http://img.huofar.com/data/jiankangrenwu/shizi.gif");

PipelineDraweeControllerBuilder pdcb= (PipelineDraweeControllerBuilder) Fresco.NewDraweeControllerBuilder()
                                               .SetAutoPlayAnimations(true);
IDraweeController draweeController = pdcb.SetUri(Uri.Parse("res://" + PackageName + "/" + Resource.Drawable.test)).Build();

SimpleDraweeView img = FindViewById<SimpleDraweeView>(Resource.Id.img);
img.Controller = draweeController;

But, this can only load the picture, the gif can't be played. Because Fresco need com.facebook.fresco:animated-gif:1.9.0 to support gif (look here ).

And NAXAM/fresco-android-binding did't bind com.facebook.fresco:animated-gif:1.9.0 in their nuget. After execute Install-Package Naxam.Fresco.Droid on Package Manager Console, you will add five packages into your project, they are:

• Naxam.Fresco.Droid
• Naxam.FrescoCore.Droid
• Naxam.FrescoDrawee.Droid
• Naxam.FrescoImagePipeline.Droid
• Naxam.FrescoImagePipelineBase.Droid .

But there is no animated-gif .

So, I suggest you to use glide to load gif, here is a simple:

var CatalogMain = System.IO.Path.Combine(Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryPictures).ToString(), "dbsoft");
Glide.With(this).AsGif().Load(new File(CatalogMain, "Main.gif")).Into(MainImage);

I have made a demo which loads the gif with both Fresco and Gilde.
