一、目标功能

请根据APP门户界面设计的源码基础，在列表页上点击跳转到另一详情页面

二、实现思路

1. 创建目标界面：首先创建一个Activity作为目标界面。

2. 设置RecyclerView：在目标界面的布局文件中定义一个RecyclerView，

3. 准备数据源：在目标界面中，准备用于显示在RecyclerView中的数据集合。

4. 绑定数据：在Adapter中实现数据与RecyclerView的绑定逻辑。创建一个继承自RecyclerView.Adapter的适配器类，并在其中实现相应的方法

5. 跳转到目标界面：在源界面中点击来跳转到目标界面。

三、代码文件

1、布局文件
