问题 I'm trying to write an app that would use the timepicker in Android, but I really would like to implement the one from iOS. I've had a couple of leads, but haven't struck anything that has worked for me.

I've found this blog that seems to give you some code for it, but I

问题 I have a "flat" dropdown picker today with over 200 items. The issue is that the list is actually a hierarchy of data so I wanted to see if there was any picker that can show a hierarchy of data so people can see where each item fits into the overall list.

问题 I'm new to smartphone programming and have joined a project using React Native and NativeBase. I'd like to include an image/icon in each Item in a Picker, which doesn't seem like an exotic concept, but it doesn't seem to be supported and I can't find anyone discussing doing it on SO or by Googling. I've tried a couple ways of adding things inside the <Picker.Item> and </Picker.Item> but anything put there seems to simply be ignored. Is it possible or is there a different approach to do what I
