Question

当我点击此Recyclerview中的项目然后转到另一个带有此引用的活动时，我想要参考，列表视图中有覆盖功能，但是recylclerview没有相同的功能

card.xml：

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="wrap_content">

Answer 1

看看这个：RecyclerView onClick

RecyclerView点击项目，获取一些数据然后转到另一个活动
