Summary: `ReactSwipeRefreshLayout` extends `SwipeRefreshLayout` which does not play nice with Android's touch handling system. There are two problems: 1. `SwipeRefreshLayout` overrides and swallows `requestDisallowInterceptTouchEvent`, which means that Views underneath the `SwipeRefreshLayout` will not interact correctly with parent Views of `SwipeRefreshLayout`. We've seen this in practice by H-ScrollViews having their touches intercepted by an enclosing ViewPager. This is fixed by passing `requestDisallowInterceptTouchEvent` up to the parents of `SwipeRefreshLayout`. 2. `SwipeRefreshLayout` overrides `onInterceptTouchEvent` and never calls `super.onInterceptTouchEvent`, therefore ignoring the value of `disallowIntercept`. That means that it will intercept some touches when it shouldn't. One such case is again the H-ScrollView, which should receive all horizontal scrolls and stop `SwipeRefreshLayout` from intercepting any touch events after scrolling. Currently, after the H-ScrollView starts scrolling, it is still possible to get the `SwipeRefreshLayout` to detect and emit refresh events. This is fixed by checking and blocking on horizontal scrolls. Reviewed By: foghina Differential Revision: D3929893 fbshipit-source-id: e6f8050fb554e53318a7ca564c49c20cb5137df9 |
