How to adjust a timestamp sequence to appear only once per day

Hello, I would like to have the date only appear once per day (so in this instance, when multiple messages were sent, the date should only appear once at the top above the first message). Same for the next upcoming days.  Ie, 7th,8th, 9th

Create a listview that contains all days and format the date there. Within this listview, put another listview that contain the messages + timestamp.
