How to refresh image view immediately

Question

In my android app, I download an image from the cloud. The download is performed in a thread and in that same thread I also set an image view with the newly downloaded image

new Thread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                while (!socket.isClosed()) {
                    imgArray = receiveImagebytes();
                }
            }
        }).start();

        try {
        Thread.sleep(5000);
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


while (!socket.isClosed()) {
            runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    // TODO Auto-generated method stub

                    imageView.setImageBitmap(BitmapFactory.decodeByteArray(imgArray, 0, imgArray.length));
                    imageView.invalidate();
                }
            });
