VerticalTabLayout

VerticalTabLayout的依赖:

    implementation 'q.rorbin:VerticalTabLayout:1.2.5'

VerticalTabLayout的xml:

<q.rorbin.verticaltablayout.VerticalTabLayout
        android:id="@+id/class_tab"
        android:layout_width="100dp"
        android:layout_height="match_parent"
        android:background="#EDEDED"
        app:indicator_color="@color/colorPrimary"
        app:indicator_width="2dp"
        app:indicator_gravity="left"
        app:tab_height="50dp"
        android:visibility="visible"
        app:tab_mode="scrollable"/>

VerticalTabLayout的适配器:

mClassTab.setTabAdapter(new TabAdapter() {
            @Override
            public int getCount() {//个数
                return list.size();
            }

            @Override
            public ITabView.TabBadge getBadge(int position) {
                return null;
            }

            @Override
            public ITabView.TabIcon getIcon(int position) {
                return null;
            }

            @Override
            public ITabView.TabTitle getTitle(int position) {//设置标题
                ITabView.TabTitle title = new ITabView.TabTitle.Builder()
                        .setContent(list.get(position).getFrist_name())//从集合中获取标题
                        .setTextColor(Color.RED,Color.BLACK)
                        .build();
                return title;

            }

            @Override//设置颜色
            public int getBackground(int position) {
                return 0;
            }
        });

VerticalTabLayout的点击事件：

 mClassTab.addOnTabSelectedListener(new VerticalTabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabView tab, int position) {
                List<ScoreClassBean.ClassFristShopBean.ShopListBeansBean> shopListBeans = list.get(position).getShopListBeans();//根据“position”获取新的集合数据
                beans.clear();//清空集合
                beans.addAll(shopListBeans);//点击后将新的数据放入集合
                scoreClassAdapter = new ScoreClassAdapter(getContext(), beans);//获取RecyclerView的适配器
                mClassRlv.setAdapter(scoreClassAdapter);//绑定RecyclerView的适配器
            }


            @Override
            public void onTabReselected(TabView tab, int position) {

            }
        });
