I have a class that inherits from DialogFragment called UnseatedPlayers which shows a list of available (unseated) players.
From another class called ActiveTable when an empty seat is clicked on the UnseatedPlayers dialog fragment appears but when I press back, the dialog fragment disappears (as expected) and I click on any of the free seats and 2 dialog fragments appears stacked on each other and if I repeat the process 4 dialog fragments and then 8 and so on.
I think it has something to do with that I create a new dialog fragment each time I click on a seat:
private void FreeSeatPlayer_Click(object sender, EventArgs e)
{
var button = sender as Button;
int seatId = (int)button.Tag;
var trans = this.FragmentManager.BeginTransaction();
var unseatedPlayers = new UnseatedPlayers(seatId);
unseatedPlayers.OnDimissEvent += UnseatedPlayers_OnDimissEvent;
unseatedPlayers.Show(trans, "unseated_players");
}
But I'm not sure as when I press back it should dismiss the dialog fragment in a correct way and according to this post:
Dismiss the fragment and its dialog. If the fragment was added to the back stack, all back stack state up to and including this entry will be popped. Otherwise, a new transaction will be committed to remove the fragment.
Why are the dialog fragments appearing on each other?
