Baserecyclerviewadapterhelper: setEmptyView的问题

[xingxingxiaoyu]

我使用setOnItemSwipeListener做滑动删除事，删除最后一条数据时报错
java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder{e2e7c33 position=0 id=-1, oldPos=1, pLpos:1 scrap [attachedScrap] tmpDetached no parent}
onItemSwiped确实是执行了，因为我的数据删除了。
于是我加上了setEmptyView 报了错
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mylift.shop/com.mylift.shop.ui.main.fragmment.mine.activity.browsing_history.BrowsingHistoryActivity}: java.lang.RuntimeException: please bind recyclerView first!
我的mRecyclerView.setAdapter(adapter);在setEmptyView 之前已经调用了。
暂时解决：然后我揣测是setEmptyView 调用早了造成的，于是我在设置上拉加载下拉刷新已经侧滑删除这些监听器之后再调用setEmptyView ，问题暂时是解决了。

出错的时候调用setEmptyView的顺序是？

[xingxingxiaoyu]

   adapter = new BrowsingHistoryAdapter(list);
    mRecyclerView.setAdapter(adapter);
    mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

//================================================================
// 没有数据的时候默认显示该布局
adapter.setEmptyView(R.layout.item_empty);
//================================================================
adapter.setOnItemClickListener。。。
adapter.setOnLoadMoreListener。。。
ItemDragAndSwipeCallback itemDragAndSwipeCallback = new 。。。
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(itemDragAndSwipeCallback);
itemTouchHelper.attachToRecyclerView(mRecyclerView);

    // 开启滑动删除
    adapter.enableSwipeItem();
    adapter.setOnItemSwipeListener。。。
    放在最后没有出错了

你用removeData方法删除的吗？用这个方法不会报错，setEmptyView放的位置应该也不会报错

[xingxingxiaoyu]

开启了滑动删除后，删除最后一条数据时报的错

[xingxingxiaoyu]

试着新写了一个例子，删除没有看到错误，不过setEmptyView报错了

如果需要可以把工程发给你们

[FrankKwok]

你传个demo到github上好了

[xingxingxiaoyu]

[FrankKwok]

@xingxingxiaoyu 无法复现错误

[xingxingxiaoyu]

这就很尴尬了。。。

[FrankKwok]

要不你在试下？

[xingxingxiaoyu]

我项目上的把setEmpty放在后面点调用没有问题，暂时不影响使用~

[BIGMONK]

同样的用法报同样的错误$.$

java.lang.RuntimeException: please bind recyclerView first!

如果是报这个，解决方案，就是你需要在初始化的时候，将 RecyclerView 传递给适配器里面进行绑定。我的处理方式是
mAdapter.setOnLoadMoreListener(new BaseQuickAdapter.RequestLoadMoreListener() {
@Override
public void onLoadMoreRequested() {

        }
    },mRv);

mRv 就是我传进去的 RecyclerView。

[Bertkiing]

You can try :,
bindToRecyclerView(RecyclerView);
mQuickAdapter.setEmptyView(layoutResId);
Hope it can help U ...
