android - Sectioning date header in a ListView that has adapter extended by CursorAdapter -

-

i trying build demo chatting app.i want show messages section headers dates "today","yesterday","may 21 2015" etc.i have managed achieve since new view method gets called whenever scroll list.the headers , messages mixed up.

for simplicity, have kept header in layouts , changing visibility(gone , visible) if date changes.

can me out this? let me know if needs more info posted in question.
