Hi guys! I have a question regarding MVVM.

Let’s say I have a ViewPager that has 3 pages and has automatic scrolling feature. (this viewpager goes back to page 1 when reaching page 3). The auto scrolling feature is PAUSED everytime the viewpager receives a touch action.

Now, should the logic of setting view pager’s current item to 1 if it reaches 3, and the pausing of auto scroll when view pager receives touch event RESIDE in ViewModel?

In my understanding. Purely UI logic can stay in activity/fragment. Logic that can reside in ViewModel can include enabling/disabling buttons (depending on the input), validating inputs, etc.

Any inputs are greatly appreciated! 🙂

Now it possible in ViewPager2 to enable/disable swiping by using myViewPager2.setUserInputEnabled(false) method.
