更便捷的多布局, 为 BaseQuickAdapter 设置代理

 public class MultiDelegateAdapter extends BaseQuickAdapter<Entity, BaseViewHolder> {

        public MultiDelegateAdapter() {
            super(null);
            //Step.1
            setMultiTypeDelegate(new MultiTypeDelegate<Entity>() {
                @Override
                protected int getItemType(Entity entity) {
                    //根据你的实体类来判断布局类型
                    return entity.type;
                }
            });
            //Step.2
            getMultiTypeDelegate()
                    .registerItemType(Entity.TEXT, R.layout.item_text_view)
                    .registerItemType(Entity.IMG, R.layout.item_image_view);
        }

        @Override
        protected void convert(BaseViewHolder helper, Entity entity) {
            //Step.3
            switch (helper.getItemViewType()) {
                case Entity.TEXT:
                    // do something
                    break;
                case Entity.IMG:
                    // do something
                    break;
            }
        }
    }

多布局代理很简单，在任何继承与BaseQuickAdapter的 adapter 上都可以实现，分为三步,如下:

Step.1

  • setMultiTypeDelegate(), 并重写getItemType() 方法
    需要说明的是Entity 并不需要实现任何接口 ，只需要能够判断出该实体对应的是哪个布局类型即可

Step.2

  • getMultiTypeDelegate().registerItemType() 设置每种type对应的布局

Step.3

  • 分 type 进行 convert() 操作

OK, 多布局就可以顺利的运行了

Make it easier for multi type situation, set a delegate for BaseQuickAdapter

 public class MultiDelegateAdapter extends BaseQuickAdapter<Entity, BaseViewHolder> {

        public MultiDelegateAdapter() {
            super(null);
            //Step.1
            setMultiTypeDelegate(new MultiTypeDelegate<Entity>() {
                @Override
                protected int getItemType(Entity entity) {
                    //infer the type by entity
                    return entity.type;
                }
            });
            //Step.2
            getMultiTypeDelegate()
                    .registerItemType(Entity.TEXT, R.layout.item_text_view)
                    .registerItemType(Entity.IMG, R.layout.item_image_view);
        }

        @Override
        protected void convert(BaseViewHolder helper, Entity entity) {
            //Step.3
            switch (helper.getItemViewType()) {
                case Entity.TEXT:
                    // do something
                    break;
                case Entity.IMG:
                    // do something
                    break;
            }
        }
    }

First, make you adapter extends BaseQuickAdapter , then achieve the following steps :

Step.1

  • setMultiTypeDelegate(), and override getItemType()
    Notice that there is no need for Entity to implement any interface , only for inferring which layout type is.

Step.2

  • getMultiTypeDelegate().registerItemType(), set layout id for every type.

Step.3

  • do convert() job for every type.

That's all.

return entity.type; 请问这里的entity.type是返回的什么呢？

tysheng commented

你自己写的，区分type

DaiFalin commented

我的实体类使用的Retrifot添加Gson转换器直接存入实体类了，可以说下采用代理的话，实体类里面怎么写呢，小白一枚。我现在安装这样写出来，RecyclerView空白。

z2700589 commented

有四种布局，但是只有两个bean，外面套一个类，应该怎么套呢，小白求大神指导。。。。

tysheng commented

@z2700589 写代码的思维灵活一点，都是很简单的
class AllBean{
int type;
BeanA b1;
BeanB b2;
}

chaoDream commented

recyclerview 嵌套recyclerview 报android.content.res.Resources$NotFoundException: Resource ID #0xfffffe6c
at android.content.res.Resources.getValue(Resources.java:1048) 这种错误，是由于什么引起的，求解决！

FrankKwok commented

@chaoDream 重新开个issue提问

zouzhenglu commented

没感觉这个委托的写法比原来的好啊

mikaelzero commented

@zouzhenglu 解决了和实体类耦合的问题 这样就不需要强制去实现MultiItemEntity接口

zouzhenglu commented

那其实重写他的getItemType就可以了，这样啊还清晰点

AaronYang23 commented

有一个疑问：这种代理情况是在哪里设置list数据集？ 构造方法没有参数传入

luao419 commented

请问想根据行号设置布局可以做得到吗

Lee-Jian commented

在哪里传数据

AaronYang23 commented

构造方法内调用setnewdata 或者 修改构造方法参数不传null，传单参数你的list

SSSSunrise commented

适配器进行 addFooterView(view) view不能有listview、Gridview、Recyclerview吗？我这边添加了不显示数据。

这个多布局可以求一个简单的demo吗？

你好 我使用多布局时没有回调MultiTypeDelegate中的getItemType方法 数据是有的

android.content.res.Resources$NotFoundException: Resource ID #0xfffffe6c 是什么原因啊，老铁？？

@SuperKe 布局类型找不到。检查一下代码

aloe20 commented

在ItemProvider中如何处理子View的点击事件呢

duoluodesonger commented

可以根据position来返回不同的布局类型吗

liz821 commented

那其实重写他的getItemType就可以了，这样啊还清晰点

这个解耦还是有好处的,比如你要抽象的一个方法里有BaseQuickAdapter 他和Mulit不是一个类型,就得写两套

krisez commented

其实跟重写getDefItemType()也可以有一样的效果吧。就继承BaseQuickAdapter.

krisez commented

@RUANHAOANDROID 多布局情况？？
你瞅瞅你是不是getViewType Bean类里面多返回了一个参数
譬如返回的0
但是 你的adapter没有对0进行操作

会出现这种问题，怎么解决？

实体类继承了MultiItemEntity，其中getItemType的返回值你应该返回的是0，正常应该返回itemType

最新版50，setMultiTypeDelegate（）这个方法是不是取消了？

@jackyHuangH
2.9.50 上使用 MultipleItemRvAdapter 代替 BaseQuickAdapter。
后面的版本应该会加回来这个函数。

@RUANHAOANDROID 多布局情况？？
你瞅瞅你是不是getViewType Bean类里面多返回了一个参数
譬如返回的0
但是 你的adapter没有对0进行操作

正如你所说，我得到了解决，谢谢

怎么解决的亲？

请问如何根据item的类型来初始化不同布局，这种只能一个holder对应一个布局，如果是聊天列表我想根据item是发送方还是接收方来实例化不同layout的布局 该如何实现
