Answer 1

Most Easy Way

TextView tv = findViewById(R.id.tv);
tv.setText("some text");
setUnderLineText(tv, "some");

Also support TextView childs like EditText, Button, Checkbox

public void setUnderLineText(TextView tv, String textToUnderLine) {
        String tvt = tv.getText().toString();
        int ofe = tvt.indexOf(textToUnderLine, 0);

        UnderlineSpan underlineSpan = new UnderlineSpan();
        SpannableString wordToSpan = new SpannableString(tv.getText());
        for (int ofs = 0; ofs < tvt.length() && ofe != -1; ofs = ofe + 1) {
            ofe = tvt.indexOf(textToUnderLine, ofs);
            if (ofe == -1)
                break;
            else {
                wordToSpan.setSpan(underlineSpan, ofe, ofe + textToUnderLine.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
                tv.setText(wordToSpan, TextView.BufferType.SPANNABLE);
            }
        }
    }
