How can i detect which fragment/tab is being utilised?

Question

My application consists of several tabs which all contain ListViews which are in a Fragment. These ListViews are populated using one class. I use a variable called current tab in order to detect which tab is selected and therefore the ListView can be populated to fit its requirements.

I have realised however, that when a tab is selected. The previous and next one are also loaded in order to increase the UI fluidity. I am currently unable to distinguish which listview is being operated on. As a result I am not able to retrieve its corresponding data.

onTabSelected will not do the job. I am wondering if there is some other function/method that will allow me to do this.

You can try to override setUserVisibleHint:

@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);
    if(isVisibleToUser){
        //called when fragment is visible to the user.
    }
}
