Android开发教程实战案例源码分享-上左联动列表
由上左顶部标签决定列表内容需求，有些维修的app上就有这样的需求
一、思路：
左右各一个RecycleView，右上面固定两个TextView
二、效果图：
三、关键代码：
public class MainActivity extends AppCompatActivity {
private ArrayList<LeftBean> leftBeans = new ArrayList<>();
private RightOutBean rightOutBeanDianshi1 = new RightOutBean();
private RightOutBean rightOutBeanDianshi2 = new RightOutBean();
