    setContentView(R.layout.activity_action_bar_main);
    try {
        rl = (RelativeLayout) findViewById(R.id.mainLayout);
        fragMentTra = getFragmentManager().beginTransaction();
        ActionBar bar = getActionBar();
        bar.addTab(bar.newTab().setText("Home").setTabListener(this));
        bar.addTab(bar.newTab().setText("Workouts").setTabListener(this));
        bar.addTab(bar.newTab().setText("Details").setTabListener(this));

        bar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM
                | ActionBar.DISPLAY_USE_LOGO & ActionBar.DISPLAY_SHOW_TITLE );
        bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

FragMent1 fram1;
FragmentTransaction fragMentTra = null;
FragMent2 fram2;
FragMent3 fram3;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_action_bar_main, menu);
    return true;
}

@Override

}

@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {

    if (tab.getText().equals("Workouts")) {
        try {
            rl.removeAllViews();
        } catch (Exception e) {
        }
        fram1 = new FragMent1();
        fragMentTra.addToBackStack(null);
        fragMentTra = getFragmentManager().beginTransaction();
        fragMentTra.add(rl.getId(), fram1);
        fragMentTra.commit();
    } else if (tab.getText().equals("Home")) {
        try {
            rl.removeAllViews();
        } catch (Exception e) {
        }
        fram2 = new FragMent2();
        fragMentTra.addToBackStack(null);
        fragMentTra = getFragmentManager().beginTransaction();
        fragMentTra.add(rl.getId(), fram2);
        fragMentTra.commit();
    } else if (tab.getText().equals("Details")) {
        try {
            rl.removeAllViews();
        } catch (Exception e) {

        fram3 = new FragMent3();
        fragMentTra.addToBackStack(null);
        fragMentTra = getFragmentManager().beginTransaction();
        fragMentTra.add(rl.getId(), fram3);
