Fragments, viewpagers, Async task

I have a view pager holding 3 fragments each fragment contains an async task that loads different urls for json data that is loaded into a custom listview in each fragment.

may problem is the view pager loads two fragments at a time, this delays the loding process, the progress dialogs from the next fragment are loaded in the current fragment. how can solve my problem.

Dont load the three pages simulatneouly when the fragment is selected load the page.

@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
    if(this.isVisible()){
        if (!isVisibleToUser) {
        // TODO your async task .
        }

    }
    super.setUserVisibleHint(isVisibleToUser);
}
