The thing is that being Clickable shouldn't have any impact in this scenario. Although a clickable view always consumes the touch event, in ViewPager's case it should intercept it when it recognizes a drag gesture (see its onInterceptTouchEvent implementation).
You should override onTouch and onInterceptTouchEvent for all your custom views and use logs to see how the events propagate through them (the proper behavior would be the button intercepting onTouch and once your finger moves enough in the X axes it should stop getting that event) My best guess is that the ViewPager cancels the drag because it believes your views have horizontal scrolling - I didnt dig all the way through, but it seems to be basing that mostly on child view sizes... since you said you have custom layout logic, i'm thinking it makes the ViewPager return the wrong result. try debugging ViewPager's canScroll method. they also have this comment in there: " // TODO: Add versioned support here for transformed views. This will not work for transformed views in Honeycomb+ ) " Kind of suspicious :) On Tuesday, October 9, 2012 11:57:28 PM UTC+2, Streets Of Boston wrote: > > The targetSdk is 11. > This is our hierarchy: > > -ViewPager > | > +-NoSaveStateFrameLayout > | > +-ProfileGridView > | > +-ProfileGridViewRow > | > +-FrameLayout > | > +-TextView > > Note that ProfileGridView contains one or more ProfileGridViewRows which > contains one or more clickable TextView (i.e. our buttons). > The ProfileGridView and ProfileGridViewRow are custom LinearyLayouts: The > have their own measure and layout-logic.
