I am creating an app that includes a message sender. In it is the ability for the main user to choose people for a project from a list. Only to them a message is sent simultaneously and they can respond. It should then be possible to change the group for others for a few months. I have searched at several topics, on youtube but can't find it properly. so I started something myself with some found examples. Listview, etc. Can you help me?
Your blocks image is difficult to read, but I cannot see anywhere blocks that are sending a message. Do you mean sending SMS ?
Ah, you are talking about chat messages ? You might want to use the dataChanged event for messages that are sent to all people. You may want a specific tag for this, or a tag for each group.
