何时使用ViewModel或Fragment newInstance函数？

Question

So the question is simple: When is it best to use a ViewModel and getting data from that versus using the newInstance function on a fragment and passing the data through the creation.

I've tried googling it, but there doesn't seem to be much out there. Not anything I can easily seem to find.

Answer 1

ViewModel together with LiveData will store the values throughout the life cycle of the Fragment/Activity. It can also observe the underlying data so when the ViewModel changes your views will be automatically notified and updated. Read more about MVVM.
