public class AndroidTabLayoutActivity extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TabHost tabHost = getTabHost();

        // Tab for Photos
        TabSpec overviewspec = tabHost.newTabSpec("Overview");
        overviewspec.setIndicator("Overview");
        Intent overviewspecIntent = new Intent(this, TulipOverviewActivity.class);
        overviewspec.setContent(overviewspecIntent);

        // Tab for Songs

        // setting Title and Icon for the Tab
        locationmapspec.setIndicator("Location Map");
        Intent locationmapspecIntent = new Intent(this, TulipOverviewActivity.class);
        locationmapspec.setContent(locationmapspecIntent);

        // Tab for Videos
        TabSpec amenitiesspec = tabHost.newTabSpec("Amenities");
        amenitiesspec.setIndicator("Amenities");
        Intent amenitiesspecIntent = new Intent(this, TulipOverviewActivity.class);
        amenitiesspec.setContent(amenitiesspecIntent);

     // Tab for Videos
        TabSpec specificationsspec = tabHost.newTabSpec("Specifications");
        specificationsspec.setIndicator("Specifications");
        Intent specificationsspecIntent = new Intent(this, TulipOverviewActivity.class);
        specificationsspec.setContent(specificationsspecIntent);


     // Tab for Videos
        TabSpec plansspec = tabHost.newTabSpec("Plans");
        plansspec.setIndicator("Plans");

        Intent plansspecIntent = new Intent(this, TulipOverviewActivity.class);
        plansspec.setContent(plansspecIntent);




        // Adding all TabSpec to TabHost
        tabHost.addTab(overviewspec); // Adding photos tab
        tabHost.addTab(locationmapspec); // Adding songs tab
        tabHost.addTab(amenitiesspec); // Adding videos tab
        tabHost.addTab(specificationsspec); // Adding videos tab
        tabHost.addTab(plansspec); // Adding videos tab

        for (int tabIndex = 0 ; tabIndex < tabHost.getTabWidget().getTabCount() ; tabIndex ++) {
            View tab = tabHost.getTabWidget().getChildTabViewAt(tabIndex);
            TextView t = (TextView)tab.findViewById(android.R.id.title);
            t.setTextColor(getResources().getColor(R.color.tab_not_select));
            t.setTextSize(12);

        }


        tabHost.setClickable(true);
        tabHost.setBackgroundColor(Color.WHITE);
       // tabHost.setPadding(10, 10, 10, 10);




        tabHost.getTabWidget().getChildAt(0).setBackgroundColor(R.drawable.tab);
        tabHost.getTabWidget().getChildAt(1).setBackgroundColor(R.drawable.tab);
        tabHost.getTabWidget().getChildAt(2).setBackgroundColor(R.drawable.tab);
        tabHost.getTabWidget().getChildAt(3).setBackgroundColor(R.drawable.tab);
        tabHost.getTabWidget().getChildAt(4).setBackgroundColor(R.drawable.tab);

       // tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#ffcd14"));
    }
