Based on the previous answers I developed the following function, you can copy/paste it

 private void highlightMask(TextView textView, String text, String mask) {
            boolean highlightenabled = true;
            boolean isHighlighted = false;

            if (highlightenabled) {
                if (!TextUtils.isEmpty(text) && !TextUtils.isEmpty(mask)) {
                    String textLC = text.toLowerCase();
                    mask = mask.toLowerCase();

                    if (textLC.contains(mask)) {
                        int ofe = textLC.indexOf(mask, 0);
                        Spannable wordToSpan = new SpannableString(text);
                        for (int ofs = 0; ofs < textLC.length() && ofe != -1; ofs = ofe + 1) {
                            ofe = textLC.indexOf(mask, ofs);
                            if (ofe == -1) {
                                break;
                            } else {
                                // set color here
                                wordToSpan.setSpan(new BackgroundColorSpan(0xFFFFFF00), ofe, ofe + mask.length(),
                                                   Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                                textView.setText(wordToSpan, TextView.BufferType.SPANNABLE);
                                isHighlighted = true;
                            }
                        }

                    }
                }
            }

            if (!isHighlighted) {
                textView.setText(text);
            }
        }
