adapter.register注册了还是报registered错误 #159

What kind of issue is this?

[ ] 注册代码如下： MultiTypeAdapter multiTypeAdapter; List
mItems; mItems = new Items(); multiTypeAdapter = new MultiTypeAdapter(mItems); multiTypeAdapter.register(MomentsBean.class, new MomentsViewBinder()); 继承： public class MomentsViewBinder extends ItemViewBinder<MomentsBean, MomentsViewBinder.ViewHolder>{}
MomentsBean里面没有泛型。
- 错误 me.drakeet.multitype.BinderNotFoundException: Do you have registered the binder for ArrayList.class in the adapter/pool? at me.drakeet.multitype.MultiTypeAdapter.indexInTypesOf(MultiTypeAdapter.java:250) at me.drakeet.multitype.MultiTypeAdapter.getItemViewType(MultiTypeAdapter.java:192)

Do you have registered the binder for ArrayList.class in the adapter/pool?

你如何 add 数据到 items 里的？

drakeet commented 7 years ago

你是不是 mItems.add(anotherList)？你如果你要往 mItems add 一个 list，你应该使用 mItems.addAll(anotherList).

renkchina commented 7 years ago

对。犯了这个低级错误。应该是用addAll。其他地方都是用addall的。

所以学会看错误信息很重要，实际上错误日志中透露的信息已经很明白了。

现在有这种场景需求，能直接注册list类型吗？
