MediatorLiveData or switchMap transformation with multiple parameters

Question

I am using Transformations.switchMap in my ViewModel so my LiveData collection, observed in my fragment, reacts on changes of code parameter.

Answer 1

I faced a similar problem. There are 2 ways to solve this:

1. Either use MediatorLiveData
2. Use RxJava as it has various operators to do such kind of complex stuff

If you don't know RxJava, then I'd recommend writing your custom MediatorLiveData class. To learn how write custom MediatorLiveData class check out this example: https://gist.github.com/AkshayChordiya/a79bfcc422fd27d52b15cdafc55eac6b
