---

A viewpager with touch and key event handling disabled by default.

Key events handling is disabled by default as with the behaviour of viewpager the fragments can change when DPAD keys are pressed and focus is on the content inside the ViewPager. This is not desirable for a top navigation bar. The fragments should preferably change only when the focused tab changes.
