PagerSlidingTabStrip: How refresh inner fragment Listview in current tab at run time and stop the loading data for next tab

问题

I got stuck into the problem with listview used with inner fragment insideNavigation-drawer-page-sliding-tab-strip viewpager tabs, that given in This git hub example.

i am using the same example and All 4 tabs having a list view with different arraylist set to there adapters.

I am using only one fragment and bases of tabs position I am loading different list data to inner fragment arrayAdapter. Also I have two buttons one is delete and another one is Add.

What I want: If I press the add button then it should add new data to the array list(based on the tab position add the new add to respective arrayList) and refresh the listview data.

In my code its refreshing the current viewing tab but in next tab listview also refreshing and taking the data of previous tab. Please help me on this, any help would be appreciated.

I have single class file for this. If my approach is wrong please let me know correct approach.
