Android TabWidget沒有自定義動作的TabHost

是否可以在沒有TabHost的情況下使用TabWidget？我想爲諸如Tabs navigation之類的舊手機的ActionBar故障回覆。Android TabWidget沒有自定義動作的TabHost

所以我只想顯示用戶選項卡並監聽點擊操作，我在哪裏獲得活動標籤ID。而已。

我知道在一般情況下，TabsNavigatin for actionBar僅用於瀏覽片段。但我很容易避免片段。：

class mTabListener implements ActionBar.TabListener { 

    private Screen screen; 

    public mTabListener(Screen screen) { 
     this.screen = screen; 
    } 

    public void onTabReselected(Tab tab, FragmentTransaction ft) { 
     screen.onTabReselected(tab, ft); 
    } 

    public void onTabSelected(Tab tab, FragmentTransaction ft) { 
     screen.onTabSelected(tab, ft); 
    } 

    public void onTabUnselected(Tab tab, FragmentTransaction ft) { 
     screen.onTabUnselected(tab, ft); 
    } 

} 


public abstract class Screen extends Activity {  
protected void addTab(String title, int what, boolean selected) { 
    if (Global.API < 11) 
     return; 

    ActionBar bar = getActionBar(); 
    Tab tab = bar.newTab() 
     .setTag(new Integer(what)) 
     .setTabListener(new mTabListener(this)) 
     .setText(title); 

    bar.addTab(tab, selected); 
} 

    public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) { 

    } 

    public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) { 
     Integer what = (Integer)tab.getTag(); 
     tabSelected(what); 
    } 

    public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) { 

    } 

    public void tabSelected(int what) { 

    } 
}

但我找不到如何將Tab按鈕添加到TabWidget;
