[query] Using livedata with stepper #265

Closed root-ansh closed 5 years ago

root-ansh commented 6 years ago

I have 2 questions here :

  1. Does StepperLayout loads all the fragments(i.e the steps) at one go? I mean , i created a sample app having a button on the click of which opens another Activity with StepperLayout's implementation and adapter . It was a simple adaptr with 2 fragments. However , on logging , I found functions of 2nd fragment/step being invocked , when the user is still on first fragment/step .

  2. While using with AAC's livedata and viewmodel , i keep getting empty lists indicating viewmodels/livedata not working properly .It might be some poor implementations on my side,(or OS's side , i heard that viewmodel/livedata don't work nicely with fragments.), but could you confirm it or provide a basic example of ideal usage with livedata ? I am a beginner developer, so just thought of confirming before adding full log scripts or steps to reproduce.

Thankyou .(And by the way, Great library, a ton of thanks!)

Hi, Regarding 1 - StepperLayout uses a ViewPager internally so the nearest Fragments to the left and right are created. If you want to do some operation once the Fragment gets selected you can use one of the callback methods to do that. Regarding 2 - could you elaborate a bit more on:

What kind of LiveData sample are you looking for?
