                            CharSequence markText = tvMark.getText();
                            CharSequence charSequence = markText.subSequence(0, markText.length() - ellipsisCount-2);
                            tvMark.setText(charSequence + "...   ");
                            tvMore.setVisibility(View.VISIBLE);
