So,I have this activity which has tabs with listviews in them, and the problems I'm facing are:
The first and second tabs are having the same content i.e. the content the second tab should have is in first and second tab.
The third tab has correct content, though this is because it only instantiates just first and second tabs initially. When I set
mViewPager.setOffscreenPageLimit(2);
all the three tabs have same content, which is that of the third tab.
But after i've scrolled to third tab and then scroll back to the first one, the first one refreshes and has correct content.
Also, the next problem is the second tab never refreshes,because its always on the right or left to the tab which is opened. I want the tabs to refresh every time they are opened since i'll be constantly changing the material in the lists.

}
Please help me, I've seen a lot of answers but couldn't solve this. Any help is appreciated.
