    FragmentPageAdapter ft;






    @Override
    public boolean onCreateOptionsMenu(Menu menu){

        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main_menu,menu);
        return true;




    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        viewpager = (ViewPager) findViewById(R.id.pager);
        ft = new FragmentPageAdapter(getSupportFragmentManager());

        actionbar = getActionBar();
        viewpager.setAdapter(ft);
        actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        actionbar.addTab(actionbar.newTab().setIcon(R.drawable.shop).setTabListener(this));
        actionbar.addTab(actionbar.newTab().setIcon(R.drawable.search1).setTabListener(this));
        actionbar.addTab(actionbar.newTab().setIcon(R.drawable.favorite).setTabListener(this));


        viewpager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

            @Override
            public void onPageSelected(int arg0) {
            actionbar.setSelectedNavigationItem(arg0);

            }

            @Override
            public void onPageScrolled(int arg0, float arg1, int arg2) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onPageScrollStateChanged(int arg0) {
                // TODO Auto-generated method stub

            }
        });

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        viewpager.setCurrentItem(tab.getPosition());

    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        // TODO Auto-generated method stub

You can solve all your problems regarding location and maps if you go through this particular tutorial. It discuss about the following issues:

• Three Action Bar Tabs as Fragments.
• Current Location.
• Maps.

EDIT For getting the current location on map, you have to use the Location Services. Implement the location listener and callbacks associated with them. You will get a latitude and a longitude value which will be your location on the map. For the code implementation please have a look at the following tutorial.

Hope this would Help!!
