Yes, you can set margin programatically using

    ProgressBar view;
    RelativeLayout.LayoutParams params = view.getLayoutParams();
    int marginInPx = convertDpToPx(20);
    params.setMargins(0,0,0,marginInPx);
    view.setLayoutParams(params);

    private int convertDpToPx(float dp){
       DisplayMetrics metrics = getResources().getDisplayMetrics();
       return (int)((int)dp * ((float)metrics.densityDpi / DisplayMetrics.DENSITY_DEFAULT));
    }

Glad I could help :) Happy Coding – Rajan Kali Mar 09 '18 at 06:58 — Rajan Kali, Mar 09 '18 at 06:58

RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(0, 0, 0, 20);
progressBar.setLayoutParams(layoutParams);

Note: The margin I added is in px you may need to convert it into dp programmatically.
