用tabhost+tabwidget+fragment实现的底部菜单栏，打开某些fragment时隐藏菜单栏

Question

在某些fragment中不想让底部菜单栏显示出来，怎么改？以下是实现的源码
private void initView() {
// TODO Auto-generated method stub
//实例化布局对象

layoutInflater = LayoutInflater.from(this);

    //实例化TabHost对象，得到TabHost  
    mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);  
    mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);   

    //得到fragment的个数  
    int count = fragmentArray.length;     

    for(int i = 0; i < count; i++){    
        //为每一个Tab按钮设置图标、文字和内容  
        TabSpec tabSpec = mTabHost.newTabSpec(mTextviewArray[i]).setIndicator(getTabItemView(i));  
        //将Tab按钮添加进Tab选项卡中  
        mTabHost.addTab(tabSpec, fragmentArray[i], null);  
        //设置Tab按钮的背景  
        mTabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.drawable.selector_tab_background);  
    } 
}


 private View getTabItemView(int index){  
        View view = layoutInflater.inflate(R.layout.tab_item_view, null);  

        ImageView imageView = (ImageView) view.findViewById(R.id.imageview);  
        imageView.setImageResource(mImageViewArray[index]);  

        TextView textView = (TextView) view.findViewById(R.id.textview);          
        textView.setText(mTextviewArray[index]);  

        return view; 
    }
