1. 一个实体类RectclerItem

public class RecyclerItem implements MultiItemEntity {    private String title;    private String content;    private int item_type;    public RecyclerItem(int item_type){        this.item_type = item_type;    }    public RecyclerItem(String title, String content){        this.title = title;        this.content = content;    }    public RecyclerItem(String title, String content, int item_type){        this.title = title;        this.content = content;        this.item_type = item_type;    }    public int getItem_type() {        return item_type;    }    public void setItem_type(int item_type) {        this.item_type = item_type;    }    public String getTitle() {        return title;    }    public void setTitle(String title) {        this.title = title;    }    public String getContent() {        return content;    }    public void setContent(String content) {        this.content = content;    }    @Override    public int getItemType() {        return item_type;    }}

2. 三个item视图文件(view_multiltem_def_item、view_list_item和view_home_list_item)

view_multiltem_def_item.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="wrap_content">    <TextView        android:id="@+id/multiltem_def_tv"        style="@style/TextStyle_14sp_666"        android:layout_width="match_parent"        android:layout_height="40dp"        android:paddingLeft="10dp"        android:gravity="center"        android:text="这是默认的布局"/></LinearLayout>

view_list_item.xml（同上）
view_home_list_item.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="wrap_content">    <TextView        style="@style/TextStyle_14sp_666"        android:id="@+id/content_text_tv"        android:layout_width="match_parent"        android:layout_height="50dp"        android:gravity="center"        android:text="这是一条内容" /></LinearLayout>

3. 适配器MultiItemQuickAdapter

public class MultiItemQuickAdapter extends BaseMultiItemQuickAdapter<RecyclerItem,BaseViewHolder> {    /**     * Same as QuickAdapter#QuickAdapter(Context,int) but with     * some initialization data.     *     * @param data A new list is created out of this one to avoid mutable list     */    public MultiItemQuickAdapter(List<RecyclerItem> data) {        super(data);        addItemType(0, R.layout.view_multiltem_def_item);        addItemType(1,R.layout.view_list_item);        addItemType(2,R.layout.view_home_list_item);    }    @Override    protected void convert(BaseViewHolder helper, RecyclerItem item) {        switch (helper.getItemViewType()){            case 0:                helper.setText(R.id.multiltem_def_tv,"悯农－－－唐代诗人李绅");                break;            case 1:                helper.setText(R.id.list_item_title_tv,item.getTitle())                        .setText(R.id.list_item_content_tv,item.getContent());                break;            case 2:                helper.setText(R.id.content_text_tv,item.getTitle() + item.getContent());                break;        }    }}

4. 实现类MultiItemQuickActivity

public class MultiItemQuickActivity extends BaseRecyclerViewActivity {    private MultiItemQuickAdapter multiItemQuickAdapter;    @Override    protected int getLayoutResId() {        return super.getLayoutResId();    }    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        titleNameTv.setText("BaseMultiItemQuickAdapter实现自定义item");        multiItemQuickAdapter = new MultiItemQuickAdapter(getListData(20));        multiItemQuickAdapter.openLoadAnimation(BaseQuickAdapter.SLIDEIN_RIGHT);        recyclerView.setAdapter(multiItemQuickAdapter);    }    @Override    protected void onRefreshComplete() {        multiItemQuickAdapter.addData(0,getListData(3));        recyclerView.scrollToPosition(0);    }}

效果图如下：
