ScrollableViewPagerContent

A tiny library which improves UX with ViewPager. This library prioritizes ViewPager's horizontal swipe action over vertical scroll of inner pager contents.

In the standard behavior of Android's ViewPager, paging swipe action of ViewPager has less priority than inner views' vertical scroll. When inner content is in scrolling state, horizontal swipe is completely ignored. However the behavior is considered bad for UX, and that's why I created this library.

Also, I noticed that some major apps implemented the same behavior. (NOTE: These are not using this library.)

• Play Store app
• Official Twitter client
• Mercari

Usage

1. Add the following line(s) to build.gradle

// the core module
implementation 'com.h6ah4i.android.scrollableviewpagercontent:scrollableviewpagercontent:1.0.0'

// if you are using RecyclerView, add this too
implementation 'com.h6ah4i.android.scrollableviewpagercontent:scrollableviewpagercontent-recyclerview:1.0.0'

// if you are using NestedScrollView, add this too
implementation 'com.h6ah4i.android.scrollableviewpagercontent:scrollableviewpagercontent-nestedscrollview:1.0.0'

// if you are using ListView, add this too
implementation 'com.h6ah4i.android.scrollableviewpagercontent:scrollableviewpagercontent-listview:1.0.0'

2-A. If using a RecyclerView for the ViewPager content

RecyclerView rv = ...;
rv.addOnItemTouchListener(new ViewPagerContentRecyclerViewTouchEventInterceptor());

2-B. If using a NestedScrollView for the ViewPager content

- <android.support.v4.widget.NestedScrollView> ...
+ <com.h6ah4i.android.scrollableviewpagercontent.nestedscrollview.ViewPagerContentNestedScrollView> ...

2-C. If using a ListView for the ViewPager content

- <ListView> ...
+ <com.h6ah4i.android.scrollableviewpagercontent.listview.ViewPagerContentListView> ...
