There are different ways to make view blur in android, But i found the easiest and fastest way to make views blur using Fresco library.

Add following dependency inside your build.gradle of your module.

   compile 'jp.wasabeef:fresco-processors:2.1.0'

And inside onCreate() of Activity.

        Fresco.initialize(this);
    setContentView(R.layout.activity_main);

    SimpleDraweeView  simpleDraweeView = (SimpleDraweeView) findViewById(R.id.sdv_image);

    //INSTANTIATE BLUR POST PROCESSOR
    Postprocessor  postprocessor = new BlurPostprocessor(this, BLUR_PRECENTAGE);

    //INSTATNTING IMAGE REQUEST USING POST PROCESSOR AS PARAMETER
    ImageRequest  imageRequest = ImageRequestBuilder.newBuilderWithSource(Uri.parse(IMAGE_URL))
            .setPostprocessor(postprocessor)
            .build();

    //INSTANTATE CONTROLLOR()
    PipelineDraweeController  controller = (PipelineDraweeController) Fresco.newDraweeControllerBuilder()
            .setImageRequest(imageRequest)
            .setOldController(simpleDraweeView.getController())
            .build();

    //LOAD BLURRED IMAGE ON SimpleDraweeView(VIEW)
    simpleDraweeView.setController(controller);
