安卓QuickAction和SQLite DB更新

Question

我已经使用here的代码和教程实现了一个QuickAction菜单。

我有一个用SQLite DB中的记录填充的ListView，当单击一条记录时，将显示QuickAction菜单。我不知道如何使用QuickAction项对所选记录执行操作(例如，当选择QuickAction项时，在数据库中更新所选记录)。

下面是我的QuickAction onclick监听器：

quickAction.setOnActionItemClickListener(new QuickAction.OnActionItemClickListener() 
{           
   @Override

   public void onItemClick(QuickAction source, int pos, int actionId) 
   {

      ActionItem actionItem = quickAction.getActionItem(pos);

      if (actionId == VIEW) 
       {
          [view the record]
       } 
       else if (actionId == UPDATE) 
        {
           [update a value in the db]
         } 
       else 
        {
          [do something else to the record]
        } 
    }
  });

仅将位置传递给OnItemClick。要更新记录，可以使用putExtra方法：

quickAction.setOnActionItemClickListener(new QuickAction.OnActionItemClickListener() 
   {            
    @Override
    public     void onItemClick(int pos) 
    {
       if (pos == 0) 
           { //View item selected                                   
        Toast.makeText(YourCurrentActivity.this, "View item selected",
               Toast.LENGTH_SHORT).show();
        } 
        else if (pos == 1)
        { //Update item selected
                Toast.makeText(YourCurrentActivity.this, "Update item selected", 
                        Toast.LENGTH_SHORT).show();
        }
         else if (pos == 2)
        { //Other item selected
                Toast.makeText(YourCurrentActivity.this, "Other item selected", 
                        Toast.LENGTH_SHORT).show();
    }                               
   }                            
});
