android - Getting same list for two tabs in tabs with listview on start of activity -

so,i have activity has tabs listviews in them, , problems i'm facing are:

the first , second tabs having same content i.e. content second tab should have in first , second tab.

the third tab has correct content, though because instantiates first , second tabs initially. when set
mviewpager.setoffscreenpagelimit(2);

all 3 tabs have same content, of third tab.

but after i've scrolled third tab , scroll first one, first 1 refreshes , has correct content.

also, next problem second tab never refreshes,because on right or left tab opened. want tabs refresh every time opened since i'll changing material in lists.

please me, i've seen lot of answers couldn't solve this. appreciated.

the problem calling setlistdata every time pager item intantiated, in turn populates customlistviewvaluesarr data of given position. list adapters directly using array cause it's defined in fragment , depending on last instantiated item, it's contents change.

change customlistviewvaluesarr local variable; create new arraylist<listmodel> object in setlistdata method , return it, use returned object customadapter constructor parameter.
