However, in the real world, this is often not the case. You have dissimilar dataset

问题 Im trying to figure out what the way to go would be in order to create date-list-items for in a chat that show from which date the messages belong to. The list would look like this: --- 1 week ago --- msg msg msg msg msg ----- today ----- msg msg msg msg One way i can do it is by creating date time list items and then using some logic to decide on which position a date-time-list-item should go.
