    'How to do' is not a good question. Show the efforts you tried. – HarshitMadhav Jan 09 '18 at 19:49
  • Do you want to blur an image on touch? – theboringdeveloper Jan 09 '18 at 19:53
  • Please read [Under what circumstances may I add “urgent” or other similar phrases to my question, in order to obtain faster answers?](//meta.stackoverflow.com/q/326569) - the summary is that this is not an ideal way to address volunteers, and is probably counterproductive to obtaining answers. Please refrain from adding this to your questions. – halfer Jan 09 '18 at 20:08

Took me 40 seconds to find the solution in stackoverflow, Please use search :)

Use the blur from here: https://stackoverflow.com/a/10028267/5618671

(Make sure to +1 Yahel, the user that posted the blur solution)

Get your Bitmap (can get it from your existing imageView), Call the fast blur when imageView has been clicked, and set the imageView with the new blurred Bitmap :

example

    imageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //GET BITMAP FROM IMAGEVIEW
            BitmapDrawable drawable = (BitmapDrawable) imageView.getDrawable();
            Bitmap bitmapFromImageView = drawable.getBitmap();
            Bitmap blurredBitmap = fastblur(bitmapFromImageView, BITMAP_SCALE, BLUR_RADIUS)
            imageView.setImageBitmap(blurredBitmap);
        }
    });

P.S Make sure imageview is declared final:

final ImageView imageView;
