+#代码
+实体类必须实现`SectionMultiEntity`，在设置数据的时候，需要给每一个数据设置`itemType`, 泛型中实体类为主体item真正数据源
+```java
+public class SectionMultipleItem extends SectionMultiEntity<Video> implements MultiItemEntity {
+
+    public static final int TEXT = 1;
+    public static final int IMG_TEXT = 2;
+    private int itemType;        // 附加字段方便处理所需逻辑
+    private boolean isMore;      // 附加字段方便处理所需逻辑
+    private Video video;         // 主体数据实体类型
+
+    // 创建section 数据
+    public SectionMultipleItem(boolean isHeader, String header, boolean isMore) {
+        super(isHeader, header);
+        this.isMore = isMore;
+    }
+
+    // 创建主体item数据
+    public SectionMultipleItem(int itemType, Video video) {
+        super(video);
+        this.video = video;
+        this.itemType = itemType;
+    }
+
+    public boolean isMore() {
+        return isMore;
+    }
+
+    public void setMore(boolean more) {
+        isMore = more;
+    }
+
+    public Video getVideo() {
+        return video;
+    }
+
+    public void setVideo(Video video) {
+        this.video = video;
+    }
+
+    @Override
+    public int getItemType() {
+        return itemType;
+    }
+}
+```
+在构造里面`addItemType`绑定type和layout的关系，adapter构造需要传入head的布局id，在convert方法里面加载item数据，在convertHead方法里面加载head数据
+```java
+public class SectionMultipleItemAdapter extends BaseSectionMultiItemQuickAdapter<SectionMultipleItem, BaseViewHolder> {
+    /**
+     * init SectionMultipleItemAdapter
+     * 1. add your header resource layout
+     * 2. add some kind of items
+     *
+     * @param sectionHeadResId The section head layout id for each item
+     * @param data             A new list is created out of this one to avoid mutable list
+     */
+    public SectionMultipleItemAdapter(int sectionHeadResId, List data) {
+        super(sectionHeadResId, data);
+        addItemType(SectionMultipleItem.TEXT, R.layout.item_text_view);
+        addItemType(SectionMultipleItem.IMG_TEXT, R.layout.item_img_text_view);
+    }
+
+    @Override
+    protected void convertHead(BaseViewHolder helper, final SectionMultipleItem item) {
+        // deal with header viewHolder
+        helper.setText(R.id.header, item.header);
+        helper.setVisible(R.id.more, item.isMore());
+        helper.addOnClickListener(R.id.more);
+    }
+
+    @Override
+    protected void convert(BaseViewHolder helper, SectionMultipleItem item) {
+        // deal with multiple type items viewHolder
+        helper.addOnClickListener(R.id.card_view);
+        switch (helper.getItemViewType()) {
+            case MultipleItem.TEXT:
+                helper.setText(R.id.tv, item.getVideo().getName());
+                break;
+            case MultipleItem.IMG_TEXT:
+                switch (helper.getLayoutPosition() % 2) {
+                    case 0:
+                        helper.setImageResource(R.id.iv, R.mipmap.animation_img1);
+                        break;
+                    case 1:
+                        helper.setImageResource(R.id.iv, R.mipmap.animation_img2);
+                        break;
+                }
+                break;
+        }
+    }
+}
+```
+section multiple类型需要继承特定实体类，满足特定规则`SectionMultiEntity`,
+```
+  public static List<SectionMultipleItem> getSectionMultiData() {
+        List<SectionMultipleItem> list = new ArrayList<>();
+        Video video = new Video(HTTPS_AVATARS1_GITHUBUSERCONTENT_COM_LINK, CYM_CHAD);
+
+        // 以下为列表的一个section item数据
+        // 每个item包含一个section + n 个 video 数据。 video 为主体item所需数据类型
+        // add section data
+        list.add(new SectionMultipleItem(true, "Section 1", true));
+        // add multiple type item data ---start---
+        list.add(new SectionMultipleItem(SectionMultipleItem.TEXT, new Video(HTTPS_AVATARS1_GITHUBUSERCONTENT_COM_LINK, "video_id_0")));
+        list.add(new SectionMultipleItem(SectionMultipleItem.TEXT, new Video(HTTPS_AVATARS1_GITHUBUSERCONTENT_COM_LINK, "video_id_1")));
+        list.add(new SectionMultipleItem(SectionMultipleItem.IMG_TEXT, new Video(HTTPS_AVATARS1_GITHUBUSERCONTENT_COM_LINK, "video_id_2")));
+        // ---end---
+
+        list.add(new SectionMultipleItem(true, "Section 2", false));
+        list.add(new SectionMultipleItem(SectionMultipleItem.IMG_TEXT, video));
+        list.add(new SectionMultipleItem(SectionMultipleItem.IMG_TEXT, video));
+        list.add(new SectionMultipleItem(SectionMultipleItem.TEXT, video));
+        list.add(new SectionMultipleItem(true, "Section 3", false));
+        list.add(new SectionMultipleItem(SectionMultipleItem.IMG_TEXT, video));
+        list.add(new SectionMultipleItem(SectionMultipleItem.TEXT, video));
+        return list;
+    }
+```
+
+数据回调，可根据adapter数据源获取主体item实体类
+```
+      sectionAdapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
+            @Override
+            public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
+                SectionMultipleItem item = (SectionMultipleItem) adapter.getData().get(position);
+                switch (view.getId()) {
+                    case R.id.card_view:
+                        // 获取主体item相应数据给后期使用
+                        if (item.getVideo() != null) {
+                            Toast.makeText(SectionMultipleItemUseActivity.this, item.getVideo().getName(), Toast.LENGTH_LONG).show();
+                        }
+                        break;
+                    default:
+                        Toast.makeText(SectionMultipleItemUseActivity.this, "OnItemChildClickListener " + position, Toast.LENGTH_LONG).show();
+                        break;
+
+                }
+            }
+        });
+```
