Question

请问我能帮助我，如何在列表中的每个项目上打开不同的片段？我已经阅读并尝试了很多东西，但不能。我想要的是

案例：0，
案例1：等......

我必须说列表不会改变顺序或大小，总是相同的项目而不是四处走动。

感谢您的回答。

Answer 1

有三种方法可以做到这一点。

1）您可以使用OnTouch为RecycleView实施gesture事件，并在切换案例中使用position。

2）在您的适配器类中，为您的xml文件的父布局创建单击侦听器，并在switch case中使用position。

3）您可以在适配器类中创建一个接口，并在父布局的click事件上注册，并使用该接口实现您的活动。
