Android TabLayout布局记载

.xml主页面布局

 <android.support.design.widget.TabLayout
        android:id="@+id/business_head"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        app:tabMode="fixed"/>

    <com.always.library.View.LrRecycleview.recyclerview.LRecyclerView     //自定义的RecyclerView
        android:id="@+id/listview"

 主MainActivity 

private static final String[] titleList = {"逾期订单，"已完成订单};

 @Override
    protected void setData() {
        initList();
        business();
 }
    private void business() {
            final LinearLayoutManager manager = new LinearLayoutManager(mContext);
            listview.setLayoutManager(manager);
            adapter = new RCommonAdapter<BussessResBean.DataBean>(mContext, R.layout.item_activity_overdue_list) {
                @Override
                protected void convert(ViewHolder holder, final BussessResBean.DataBean bean, int position) {
                }
            };
            adapter.setOnItemClickListener(new RMultiItemTypeAdapter.OnItemClickListener<BussessResBean.DataBean>() {
                @Override
                public void onItemClick(RecyclerView.ViewHolder holder, BussessResBean.DataBean data, int position) {
                  //点击具体订单完成的事件
                }
            });
            LRecyclerViewAdapter mLRecyclerViewAdapter = new LRecyclerViewAdapter(adapter);
            listview.setEmptyView(emptyView);
            listview.setAdapter(mLRecyclerViewAdapter);
            listview.setOnRefreshListener(new OnRefreshListener() {
                @Override
                public void onRefresh() {
                    getData();
                }
            });
            listview.setRefreshing(true);
    }
  private void initList() {

        for (int i = 0; i < titleList.length; i++) {    //遍历数组
            View inflate = LayoutInflater.from(mContext).inflate(R.layout.item_tab, null);  //单个模块
            ((TextView) inflate.findViewById(R.id.tv_title)).setText(titleList[i]);   //填入模块名称     
       bushead.addTab(bushead.newTab().setCustomView(inflate));  //把有名称的模块放入TabLayout中

bushead.addOnTabSelectedListener(new TabLayout.BaseOnTabSelectedListener() {
    @Override
    public void onTabSelected(TabLayout.Tab tab) {
        int position = tab.getPosition();
        switch (position) {
            case 0:
                status = "0";
                break;
            case 1:
                status = "1";
                break;


        }
        listview.setRefreshing(true);
    }

    @Override
    public void onTabUnselected(TabLayout.Tab tab) {

    }


    @Override
    public void onTabReselected(TabLayout.Tab tab) {

    }

});

} }

其中getdata（）为获取RecyclerView数据

TabLayout子布局item_tab如下

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:orientation="horizontal"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:padding="8dp">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text=""
        android:id="@+id/tv_title"
        android:layout_gravity="center"
        android:textColor="@color/defcolor0"
        android:textSize="@dimen/textsize_15" />

</LinearLayout>

代码这里只贴出重要部分，

逻辑是先声明布局，然后遍历TabLayout的数组，

当点击第一个item的时候，状态为0，通过getData()；方法根据状态通过接口获取到，订单数据，声明一个adapter

用户展示订单详情，这样就把Tablayout和下方的RecyclerView关联起来了，实现点击一个TabLayout中的item

展示出来的订单数和信息均不相同的功能
