Android TextWatcher StackOverflow error

Question

I ALREADY know there are many questions asking the same thing, but they don't work for me. Here is the code (I use the code to color a text part in a EditText) -

et_note.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }
            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                if (textCC.contains("sample_text")) {
            String syntaxText = "sample_text";
            int ofe = textCC.indexOf(syntaxText, 0);
            int nextOfe = textCC.indexOf(syntaxText, ofe);
            for (int ofs = 0; ofs < textCC.length() && ofe != -1 && nextOfe != -1; ofs = nextOfe + 1) {
                ofe = textCC.indexOf(syntaxText, ofs);
                nextOfe = textCC.indexOf(syntaxText, ofe + 1);
                if (ofe == -1 || nextOfe == -1) {
                    break;
                } else {
                    Spannable WordtoSpan = new SpannableString(et_note.getText());
                    WordtoSpan.setSpan(new ForegroundColorSpan(0xFF00FF00), ofe, nextOfe + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                    et_note.setText(WordtoSpan, TextView.BufferType.SPANNABLE);
                }
            }
        }
            }
            @Override
            public void afterTextChanged(Editable editable) {
            }
        });

It gives Stack Overflow error.

Answers that work but are not suitable -

1) Add et_note.removeTextChangedListener(this) before the code and add et_note.addTextChangedListener(this) after the code - This one works but NOT properly and the app becomes VERY slow.

Any other ways that will help me? Thanks.

Answer 1

Thanks to CommonsWare, I found the answer. Just posting this answer to help others. This solved my problem -
Instead of this,

Spannable WordtoSpan = new SpannableString(et_note.getText());
                WordtoSpan.setSpan(new ForegroundColorSpan(0xFF00FF00), ofe, nextOfe + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                et_note.setText(WordtoSpan, TextView.BufferType.SPANNABLE);

I used this -

et_note.getText().setSpan(new ForegroundColorSpan(0xFF00FF00), ofe, nextOfe + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
