Java JSONParser中的OnItemClickListener方法重写另一个活动中的OnItemLongClickListener

我正在尝试从通过URL接收的Json对象创建收藏夹列表

当我得到Json数组时，我定义了方法

OnItemLongClickListener

和

OnItemClickListener

，它们得到不同的结果：

• OnItemClickListener

  方法必须打开另一个包含产品描述的活动

• OnItemLongClickListener

  方法必须将产品添加到收藏夹列表中

我在

MainActivity

中定义的方法

OnItemClickListener

的问题是我在

FragmentActivity

中定义的覆盖方法

OnItemLongClickListener

和方法

OnItemLongClickListener

根本不起作用，然后我尝试在

FragmentActivity

中定义这两种方法但在那之后，这两种方法根本不起作用

有没有办法确定这个问题
