RecyclerView:检测到不一致。无效项位置

我们的QA检测到一个错误:当旋转Android设备(Droid Turbo)时，发生了以下recyclerview相关的崩溃:

java.lang.IndexOutOfBoundsException: 不一致。无效项位置2(偏移量:2).state:3

对我来说，它看起来像一个内部错误在RecyclerView，因为我不能想到这是由我们的代码直接引起的任何方式…

有人遇到过这个问题吗?

解决方案是什么?

一个残酷的解决方法可能是在异常发生时捕获异常并从头重新创建RecyclverView实例，以避免留下损坏的状态。

但是，如果可能的话，我希望更好地理解这个问题(也许从根源上解决它)，而不是掩盖它。

这种细菌不容易繁殖，但一旦发生就会致命。

在我修改适配器实现以使用项数组的副本而不是引用之后，问题就消失了。每次在RecyclerView中显示新项目时，都会调用setItems()方法。

而不是:

private class MyAdapter extends RecyclerView.Adapter<ItemHolder> {
     private List<MyItem> mItems;  

    (....)

    void setItems(List<MyItem> items) {
        mItems = items;
    }
}

我做了:

void setItems(List<MyItem> items) {
    mItems = new ArrayList<>(items);
}

使用notifyDataSetChanged()代替notifyItem…在这种情况下。

我发现设置 mRecycler.setLayoutFrozen(真正的); 在swipeContainer的onRefresh方法中。

帮我解决了问题。

swipeContainer.setOnRefreshListener(new   SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            orderlistRecycler.setLayoutFrozen(true);
            loadData(false);

        }
    });

Sorry For late but perfect solution: when you try to remove a specific item just call notifydatasetchange() and get these item in bindviewholder and remove that item and add again to the last of list and then chek list position if this is last index then remove item. basically the problem is come when you try to remove item from the center. if you remove item from last index then there have no more recycling and also your adpter count are mantine (this is critical point crash come here) and the crash is solved the code snippet below .

 holder.itemLayout.setVisibility( View.GONE );//to hide temprory it show like you have removed item

        Model current = list.get( position );
        list.remove( current );
        list.add( list.size(), current );//add agine to last index
        if(position==list.size()-1){// remove from last index
             list.remove( position );
        }

我也有同样的问题。它发生在我快速滚动和调用API和更新数据时。在尝试了所有防止崩溃的方法后，我找到了解决方案。

mRecyclerView.stopScroll();

它会起作用的。

这个异常在API 19、21上引发(但不是新的)。在Kotlin协程中，我加载了数据(在后台线程)，并在UI线程中添加并显示它们:

adapter.addItem(item)

适配器:

var list: MutableList<Item> = mutableListOf()

init {
    this.setHasStableIds(true)
}

open fun addItem(item: Item) {
    list.add(item)
    notifyItemInserted(list.lastIndex)
}

由于某些原因，Android渲染速度不够快或其他原因，所以，我更新了RecyclerView的post方法中的列表(添加，删除，更新项目的事件):

view.recycler_view.post { adapter.addItem(item) }

此异常类似于“无法在滚动回调中调用此方法”。滚动回调可能在测量和布局传递期间运行，其中您不能更改theRecyclerView数据。任何可能改变RecyclerView结构或适配器内容的方法调用都应该延迟到下一帧。": Recyclerview -不能在滚动回调中调用此方法。
