I can't seem to get this right. There are some old post on this subject but non of them offer a working solution. This is what I'm trying to get done:
- Timepicker in 24hour format instead of am/pm
- Custom interval, for example 15 minute or 20 minute interval in the picker
- The custom picker must be able to show when Focus() is set in code
works easily in iOS but can't get the Android customrenderer to work 
Anyone any ideas?
