RealmSearchAdapter不重新显示视图

Question

我有一个gridview项目,我可以增加或减少其值,发生的是当我更改项目的值并向下滚动屏幕并向后滚动我所做的更改已经消失,如果我向下滚动几次,我可以看到我再次做出的改变,我在这里失踪了什么？

public class SearchItemViewAdapter extends RealmSearchAdapter<Itens, SearchItemViewAdapter.ViewHolder> implements RealmChangeListener {

    public SparseBooleanArray mSparseBooleanArray;

    public SearchItemViewAdapter(Activity context, Realm realm, String filterColumnName) {
        super(context, realm, filterColumnName);
        mSparseBooleanArray = new SparseBooleanArray();

    }

    @Override
    public void onChange() {
        notifyDataSetChanged();
    }

    public RealmList<Itens> getCheckedItems() {
        RealmList<Itens> mTempArry = new RealmList<>();

        for (int i = 0; i < realmResults.size(); i++) {
            if (mSparseBooleanArray.get(i)) {
                mTempArry.add(realmResults.get(i));
            }
        }


        return mTempArry;
    }


    public class ViewHolder extends RealmSearchViewHolder {

        public SearchItemView itemView;

        public ViewHolder(FrameLayout container, TextView footerTextView) {

        }

        public ViewHolder(SearchItemView itemView) {

        viewHolder.itemView.check.setChecked(mSparseBooleanArray.get(position));
