Capture swipe to dismiss listview gestures in ViewPager

阅读更多关于 Capture swipe to dismiss listview gestures in ViewPager

问题 I have a ListView that captures swipe gestures to delete a row. This ListView lives in a Fragment . On phones this is in it's own Activity and works great. On tablets this Fragment is in a ViewPager and the ListView is never able to capture any of the the swipe events since they always go to the ViewPager . How would I go about making sure swipe gestures are captured by the ListView to consume before they are passed to the ViewPager ? P.S. I am using this library for my swipe to dismiss

I tried to look answers but I couldn't find any. So I want to change my ListView items order in app and I don't have any idea how to do that.
