在android中从ContextMenu获取选项卡索引

我为选项卡添加了一个上下文菜单，我想在用户单击菜单项“close tab”时关闭选项卡。但我无法获取用户longpress所在选项卡的索引。这是我的密码

    @Override
    public void onCreateContextMenu (ContextMenu menu, View v, ContextMenuInfo menuInfo) {
        menu.setHeaderTitle("Options");
        menu.add("Close Tab");
    }
    @Override
    public boolean onContextItemSelected (MenuItem item) {
        if (item.toString().equals("Close Tab")){
             TabHost tabHost = getTabHost();
             int index = code required ?????????
                     int Itemcount = tabHost.getTabWidget().getTabCount();
             if (Itemcount > 1){;
                  tabHost.setCurrentTab(index);
                  tabHost.getTabWidget().removeView(tabHost.getTabWidget().getChildTabViewAt(index));
             }


        }

使用item.getTitle（）…尝试以下操作

  @Override
public boolean onContextItemSelected (MenuItem item) {
    if (item.getTitle().toString().equals("Close Tab")){
         TabHost tabHost = getTabHost();
         int index = code required ?????????
                 int Itemcount = tabHost.getTabWidget().getTabCount();
         if (Itemcount > 1){;
              tabHost.setCurrentTab(index);
              tabHost.getTabWidget().removeView(tabHost.getTabWidget().getChildTabViewAt(index));
         }


    }

谢谢，但我在找“需要代码”部分。获取当前触摸选项卡的索引。
