public class MainActionbarActivity extends TabActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_actionbar);

        // Your Tab Titles
        String tab_title[] = { "", "", "","" };

        // Your Tab Drawables for their states
        int tab_drawables[] = { R.drawable. tab_location_custom,
                R.drawable.tab_network_custom, R.drawable.tab_editprofile_custom,
                R.drawable.tab_home_custom };

        // Your Tab Activities
        Object tab_act[] = { PatientTrackingActivity.class, SocialNetworkActivity.class, EditProfileActivity.class, Homepage.class };

        // / TabHost setup
        final TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);
        tabHost.setup();

        TabSpec tab_spec;

        for (int i = 0; i < tab_act.length; i++) {
            tab_spec = tabHost.newTabSpec(tab_title[i]);
            tab_spec.setIndicator(tab_title[i],
                    getResources().getDrawable(tab_drawables[i]));
            tab_spec.setContent(new Intent(this, (Class<?>) tab_act[i]));
            tabHost.addTab(tab_spec);
        }
        tabHost.setCurrentTab(0);
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {
            MainActionbarActivity.this.finish();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
