ViewPager loads different fragment, and some fragment contains edit text. My problem is that, on click of edit text screen is resizing only inside viewPager fragment not complete activity. If I use adjust pan my toolbar is moving out of the view and on using adjustResize view pager contents are only moving. I want my toolbar should be fixed and content in my main activity should resize.

Hoping for quick solution..
