调用notifyItemChanged时，Android recyclelerview不更新持有者，有效负载没有值

Question

我有问题。当我更新ListView的一个视图时，我会通知一个项目。数据有2项。

但是当我用有效负载调用notifyItem时，有效负载返回数组无。在我以不同的观点称呼成功之前，我不知道为什么。

RecyclerView通过电话更新updateStatusIconCheckLanguage处的一项。我检查正常更新按钮没有值有效负载。可以帮助你？感谢。

这是代码：

public class HistoryAdapter
        extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private List<HistoryModel> mDataLists;
    private ViewHolder mViewHolder;
    private IViewCallback mCallback;

    public HistoryAdapter() {
        mDataLists = new ArrayList<>();
    }

    public void fillData(List<HistoryModel> modelList) {
        if (modelList == null) {
            return;
        }

        //remember  order item.
        mDataLists = new ArrayList<>();
        mDataLists.addAll(modelList);
        notifyDataSetChanged();
        updateStatusIconCheckLanguage(KEY_TYPE_LANGUAGE.KEY_VN);
    }

    public void updateStatusIconCheckLanguage(KEY_TYPE_LANGUAGE keyTypeLanguage) {
        if (keyTypeLanguage != null) {
            if (mDataLists != null) {
                for (int i = 0; i < mDataLists.size(); i++) {
                    notifyItemChanged(i, 34444);
                    CommonUtils.showLogDebug("notifyItemChanged");
                }
            }
        }
    }

    public void cleanupResources() {
        if (mViewHolder != null) {
            mViewHolder.cleanupResources();
            mViewHolder = null;
        }
        mDataLists = null;

        // Refresh your adapter.
        notifyDataSetChanged();
    }
