一、BaseMultiItemQuickAdapter使用步骤

1、Bean继承implements MultiItemEntity 并实现其方法

public class SmartRefreshBean implements MultiItemEntity {

    /**
     * id : 24
     * name : 时尚
     * alias : null
     * description : 优雅地行走在潮流尖端
     * bgPicture : http://img.kaiyanapp.com/22192a40de238fe853b992ed57f1f098.jpeg
     * bgColor :
     * headerImage : http://img.kaiyanapp.com/c9b19c2f0a2a40f4c45564dd8ea766d3.png
     * defaultAuthorId : 2160
     */

    private int id;
    private String name;
    private Object alias;
    private String description;
    private String bgPicture;
    private String bgColor;
    private String headerImage;
    private int defaultAuthorId;
    private int itemType=0;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Object getAlias() {
        return alias;
    }

    public void setAlias(Object alias) {
        this.alias = alias;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getBgPicture() {
        return bgPicture;
    }

    public void setBgPicture(String bgPicture) {
        this.bgPicture = bgPicture;
    }

    public String getBgColor() {
        return bgColor;
    }

    public void setBgColor(String bgColor) {
        this.bgColor = bgColor;
    }

    public String getHeaderImage() {
        return headerImage;
    }

    public void setHeaderImage(String headerImage) {
        this.headerImage = headerImage;
    }

    public int getDefaultAuthorId() {
        return defaultAuthorId;
    }

    public void setDefaultAuthorId(int defaultAuthorId) {
        this.defaultAuthorId = defaultAuthorId;
    }

    public void setItemType(int itemType) {
        this.itemType = itemType;
    }

    @Override
    public int getItemType() {
        return itemType;
    }
}

2、Adapter继承BaseMultiItemQuickAdapter

public class SmartRefreshMultiAdapter extends BaseMultiItemQuickAdapter<SmartRefreshBean, 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 SmartRefreshMultiAdapter(List<SmartRefreshBean> data) {
        super(data);
        addItemType(1, R.layout.item_smart_refresh);
        addItemType(2, R.layout.item_smart_refresh_2);
    }

    @Override
    protected void convert(BaseViewHolder helper, SmartRefreshBean item) {
        switch (helper.getItemViewType()) {
            case 1:
                helper.setText(R.id.tv_item_smart_refresh, item.getName());
                GlideApp.with(mContext).load(item.getBgPicture()).into((ImageView) helper.getView(R.id.iv_item_smart_refresh));
                break;
            case 2:
                helper.setText(R.id.tv_item_smart_refresh_2, item.getName());
                break;
        }
    }
}

3、presenter提供数据并设置ItemType

 public void getData() {
        model.getSmartRefreshData()
                .subscribeOn(Schedulers.io())
                .unsubscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .compose(RxLifeCycleUtils.<List<SmartRefreshBean>>bindToLifecycle(view))
                .map(new Function<List<SmartRefreshBean>, List<SmartRefreshBean>>() {
                    @Override
                    public List<SmartRefreshBean> apply(List<SmartRefreshBean> smartRefreshBeanList) throws Exception {
                        List<SmartRefreshBean> list = new ArrayList<>();
                        for (int i = 0; i < smartRefreshBeanList.size(); i++) {
                            if (i % 2 == 0) {
                                smartRefreshBeanList.get(i).setItemType(1);
                            } else {
                                smartRefreshBeanList.get(i).setItemType(2);
                            }
                            list.add(smartRefreshBeanList.get(i));
                        }
                        return list;
                    }
                })
                .subscribe(new CustomerSubscribe<List<SmartRefreshBean>>() {
                    @Override
                    public void onNext(List<SmartRefreshBean> smartRefreshBeans) {
                        view.showContent(smartRefreshBeans);
                    }
                });
    }

4、具体调用

public class SmartRefreshActivity extends BaseActivity<SmartRefreshPresenter> implements SmartRefreshContract.ISmartRefreshView {
    @BindView(R.id.srl_smart_refresh)
    SmartRefreshLayout srl_smart_refresh;
    @BindView(R.id.rv_smart_refresh)
    RecyclerView rv_smart_refresh;
//    private SmartRefreshAdapter adapter;
    private SmartRefreshMultiAdapter adapter;
    private List<SmartRefreshBean> smartRefreshBeanList = new ArrayList<>();

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_smart_refresh);
        ButterKnife.bind(this);
        presenter = new SmartRefreshPresenter(this);
        srl_smart_refresh.setOnRefreshListener(new OnRefreshListener() {
            @Override
            public void onRefresh(RefreshLayout refreshLayout) {
                presenter.getData();
            }
        });
        srl_smart_refresh.setEnableLoadMore(false);
//        adapter = new SmartRefreshAdapter(smartRefreshBeanList);
        adapter = new SmartRefreshMultiAdapter(smartRefreshBeanList);
        rv_smart_refresh.setLayoutManager(new LinearLayoutManager(this));
        rv_smart_refresh.setItemAnimator(new DefaultItemAnimator());
        rv_smart_refresh.setHasFixedSize(true);
        rv_smart_refresh.setAdapter(adapter);
        srl_smart_refresh.autoRefresh();
    }

    @Override
    public void showContent(List<SmartRefreshBean> smartRefreshBeans) {
        srl_smart_refresh.finishRefresh();
        srl_smart_refresh.finishLoadMore();
        smartRefreshBeanList.clear();
        smartRefreshBeanList.addAll(smartRefreshBeans);
        adapter.notifyDataSetChanged();
    }
}
