Swipe Views are an efficient way to allow the user to laterally navigate among related data items spread across multiple panes using a simple touch gesture (swipes/flings), making access to data faster and much more enjoyable. Think of the android home screen where you can swipe across multiple sibling screens or the facebook or twitter app with multiple screens (and their respective tabs) where you can just swipe to navigate through them. The entire experience is super interactive and fun. They’re basically equivalent to slideshows/carousels which has sections with/without tabs (or similar controls to navigate) in the web development arena.

Think of a slideshow of images or a step-based process like e-commerce checkouts. Basically whenever you want to swipe through a set of related sections but show only one at a time then you can leverage ViewFlipper or ViewSwitcher class widgets that Android provides us. The detection of gestures can be achieved with major use of the MotionEvent class but we’ll make use of GestureDetector for this article.

Gestures are those subtle motions to trigger interactions between the touch screen and the user. It lasts for the time between the first touch on the screen to the point when the last finger leaves the surface. We’re all familiar with it as it’s the most common way to communicate with apps on our mobiles, tablets, etc. these days. Some examples are scrolling in an app by swiping vertically/horizontally, pinch to zoom, long press to select and so on.
