I am currently developing an App using Xamarin.Forms. In my App I use two TimePickers to set a start and an ending time for some intervals. Those intervals are not supposed to overlap, so I have to check if the time a user selected is interfering with another interval. If the user selects "OK" and the time is valid the TimePicker should be dismissed, if not I would like to display a message and keep the TimePicker in place.
I already figured that I will need a custom renderer in the Android / IOs Projekts for this, I just don't really know what to do there.
For now an android solution would be sufficient for me. Could anyone help me?
Thanks in advance,
