Answer 1

ImageRequest request = ImageRequestBuilder.newBuilderWithSource(<your url>) .setPostprocessor(new IterativeBoxBlurPostProcessor(7)) .build();

然后 DraweeController controller = Fresco.newDraweeControllerBuilder() .setImageRequest(request) .setOldController(<your imageView>.getController()) .build(); imageRest.setController(controller);

Answer 2

这是简单的解决方案：

Postprocessor postprocessor = new BlurPostprocessor(this,50);
        ImageRequest imageRequest = ImageRequestBuilder.newBuilderWithSource(Uri.parse(url))
                .setPostprocessor(postprocessor)
                .build();
        PipelineDraweeController controller = (PipelineDraweeController) Fresco.newDraweeControllerBuilder()
                .setImageRequest(imageRequest)
                .setOldController(background.getController())
                .build();
        background.setController(controller);
