Just for kicks, what happens if you don't create a new fragment every time
you change tabs? Only create it once, something like this tutorial:
http://www.truiton.com/2015/06/android-tabs-example-fragments-viewpager/
Note, I'm not endorsing that tutorial or anything... I don't see anything
immediately wrong with your code (related to the tabs anyway) but I figured
this tutorial should work, and that is the main difference I see between
your code and this tutorial.
