Android アプリのフラグメントを使用しており、actionbarsherlock を使用しています。エミュレーターでアプリを実行しようとすると、ボタンが表示されず、フラグメント タブのみが表示されます。

主な活動コード:

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionbar = getSupportActionBar();
actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionbar.setTitle("Dancing Fountain");
ActionBar.Tab Frag1Tab = actionbar.newTab().setText("Song List");
ActionBar.Tab Frag2Tab = actionbar.newTab().setText("About");
Fragment Fragment1 = new Fragment_1();
Fragment Fragment2 = new Fragment_2();
Frag1Tab.setTabListener(new MyTabsListener(Fragment1));
Frag2Tab.setTabListener(new MyTabsListener(Fragment2));
actionbar.addTab(Frag1Tab);
actionbar.addTab(Frag2Tab);
