SpannableString permissionString = new SpannableString(permissionText);

int permissionStartIndex = 0;
int permissionEndIndex = 7;

int color = Color.parseColor("#3074f0");

//글자색 일부 변경 "앱 접근 권한" 까지만 적용됨
permissionString.setSpan(new ForegroundColorSpan(color), permissionStartIndex, permissionEndIndex, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

//Bold Style
permissionString.setSpan(new StyleSpan(Typeface.BOLD), permissionStartIndex, permissionEndIndex, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
