Android recycleview 多布局

在Android开发项目中我们会经常遇到过列表多部局如下:
这里写图片描述
那么这又是如何实现的呢其实很简单
main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <android.support.v7.widget.RecyclerView        android:id="@+id/recycler_view"        android:layout_width="match_parent"        android:layout_height="match_parent" /></LinearLayout>

布局写完了开始写代码

/** * Created by zhm . */public class RecyCleTypeClass extends Activity {    private RecyclerView mRecycleView;    private YueZhiPerSionAdapter adapter;    private List<Map<String, String>> mapList;    private Map<String, String> map;    //数据源    private List<String> ml = new ArrayList<>();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        mRecycleView = (RecyclerView) findViewById(R.id.recycler_view);        mRecycleView.setLayoutManager(new LinearLayoutManager(this));        mapList = new ArrayList<>();//这里模拟服务器返回来的数据类型        ml.add("类型1");        ml.add("类型2");        ml.add("类型2");        ml.add("类型1");        ml.add("类型2");        ml.add("类型1");        for (int i = 0; i < ml.size(); i++) {            map = new HashMap<>();            if (ml.get(i).equals("类型1")) {                map.put("ListType", "0");                map.put("wenzi", "这是类型1横向排列");            } else {                map.put("ListType", "1");                map.put("tupian", "这是类型2纵向排列" +                        "");            }            mapList.add(map);        }        adapter = new YueZhiPerSionAdapter(mapList);        mRecycleView.setAdapter(adapter);    }}

自定义Adapter
