When I put ListView in ScrollView, it scrolls to the bottom when updating ListView.

Asked 2 months ago, Updated 2 months ago, 1 views

Use ViewPager for Activity with ScrollView as Root and
We are trying to create a top cover image + horizontal scrolling page like the one below.

The Fragment on the page is created in ListView and the content is displayed in a list format, but when I call notifyDataSetChange() in ListView, the entire screen is scrolled to the bottom.
Also, when you call the ViewPager setCurrentItem(), it scrolls to the bottom as well.

Please let me know if anyone knows any effective means of this event.

The mystery is that the contents of ScrollView are not in LinerLayout.
I think it will be solved if I put it in LinerLayout...

Also, is it because there is no view to display tab and Fragment?
