Detect which position on tab layout

I want to know or someone to give me an idea to detect which position I am on a tab layout, i got a tab layout and i cant seem to figure out where i should do what i want, i tried doing it here at an extended FragmentPagerAdapter:

@Override
public CharSequence getPageTitle(int position) {
    // Generate title based on item position

    return tabTitles[position];
}

Basically i check if im at position 1 and do what ever and then do something else but it doesnt work, only calls the code once and neva again ANd here at an extended fragment

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = null;

    switch (p) {
        case 1:
            view = RenderFactory.getClass("Page1", inflater, container).displayContent();
            break;
        case 2:
            view = RenderFactory.getClass("Page2", inflater, container).displayContent();
            break;
        case 3:

            view = RenderFactory.getClass("Page3", inflater, container).displayContent();
            break;

    }
    return view;
}

here i just put the code within each case and the code doesnt get called more then once. Any ideas ??

Try to with addOnTabSelectedListener. This event handler gives you the position of the chosen tab.

Example:

tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {

            }

            @Override
            public void onTabUnselected(TabLayout.Tab tab) {

            }

            @Override
            public void onTabReselected(TabLayout.Tab tab) {

            }
        });

You can get the current item with this code :

tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener(){
    @Override
    public void onTabSelected(TabLayout.Tab tab){
        int current_position = tab.getPosition();
    }
});

or :

int current_position = mViewPager.getCurrentItem();
