模糊后如何返回原始 SimpleDraweeView

Question

I've have SimpleDraweeView(Fresco). How can I return back original image after blurring?

Blur code:

val blurController = Fresco.newDraweeControllerBuilder()
   .setImageRequest(
       ImageRequestBuilder.newBuilderWithSource(Uri.parse(imageUrl))
           .setPostprocessor(IterativeBoxBlurPostProcessor(7))
           .build()
   )
   .setOldController(image.controller)
   .build()

image.controller = blurController 

Answer 1

You can simply set uri for SimpleDraweeView like this:

var offBlur=view.findViewById<ImageButton>(R.id.blur_off)
offBlur.setOnClickListener { 
    image.setImageURI(uri)  // this line
}

After set uri again, blur effect will disappear.
