java - 当调用RecyclerView Adapter的 "notifyDataSetChanged() "时，RecyclerView抛出 "java.lang.Throwable: addInArray "

Question

Activity，Activity中有一个RecyclerView，通过getGroupList()获取数据，这是一个异步方法。

public void getSelectGroupList() {
    getGroupList(getGroupList_listener);
}

private LogicTaskListener<UserGroupModel> getGroupList_listener = new     LogicTaskListener<UserGroupModel>() {
        @Override
        public void onResponse(UserGroupModel result) {
            loadingFinish();
            if (result.code == KoalaHttpStatus.OK) {
                mAdapter.setData(result.data.list);
            }
        }
    };

Adapter，通过setData方法更新数据，当调用setData() notifyDataSetChanged()时，抛出java.lang.Throwable: addInArray

public void setData(List<UserGroupBean> data) {
    this.data.clear();
    this.data.addAll(data);
    notifyDataSetChanged();
}

可抛出的信息:

Answer 1

请使用 RecyclerView 的 Adapter 进行 notifyDataSetChanged()，当 RecyclerView 的数据发生变化需要更新时。

mAdapter.notifyDataSetChanged();
