问题 I have a ViewPager2 with a fragment inside, in the fragment, I have a custom view with certain touch logic that involves moving the finger. how do I prevent the ViewPager from swiping while the inner view intercepts the touch event? override fun onTouchEvent(event: MotionEvent?): Boolean { if (event?.action == MotionEvent.ACTION_DOWN || event?.action == MotionEvent.ACTION_MOVE) { //Do some stuff here } return true } while swiping this view the view pager still swipes to other pages. 回答1: Set

问题 My TabLayout (containing 5 tabs) doesn't seem to behave with ViewPager2 properly for some reasomn. The app loads fine but when I click Tab D, it goes to Tab E instead. Why does that happen and what can be done to fix this? Activity Fragment class MyFragment : androidx.fragment.app.Fragment() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) } override fun onCreateView( inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View?

问题 I am trying to use the View Pager on React Native and I am using the reference link for help https://reactnativecode.com/create-viewpager-with-tab-title-dot-indicators/?unapproved=42387&moderation-hash=570c68d8ea5535b832994536ba239b28#comment-42387 When I use the code as it is and run, it gives an error - ViewPagerAndroid has been removed from React Native.

问题 I am facing this rather strange problem with viewPager2. I did some reading and found out that viewPager2 has a default offset limit of 0 which is perfect for my application. I'm using it with a tab layout and I have 3 fragments (Home, Profile, Notification).

问题 I am following the MVVM pattern - meaning I have a ViewModel for each Fragment. I added two tabs by using ViewPager2. My adapter looks like this: @Override public Fragment createFragment(int position) { switch (position) { case 0: return new MergedItemsFragment(); case 1: return new ValidatedMergedItemsFragment(); } return new MergedItemsFragment(); } The tabs are working. However, I noticed that the ViewModel of my MergedItemsFragment is behaving weirdly. Before I added tabs I navigated to
