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。

One way I managed to fix this (in a Kotlin app with architecture components) was by setting if (recyclerView.adapter == null) recyclerView.adapter = MyAdapter(datasource) after I fetched the data from the Repository. Apparently it might have something to do with async issues with the suspend functions in the repository because when I fetch data for the first time when starting the activity, it calls the REST API since there is no data in the db, and everything goes smoothly, but after that, that same query cannot be made again, causing a crash.

林特给了我一个关于不一致性的建议: 我写了(onBindViewHolder()):

pholder.mRlayout.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        doStuff(position);
                    }
                });

它必须被替换为:

pholder.mRlayout.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        doStuff(pholder.getAdapterPosition());
                    }
                });

在你的代码中运行这两个代码，然后运行Lint得到完整的解释!!

Use 

notifyDataSetChanged()

而不是

notifyItemRangeInserted(0, YourArrayList.size())

在这种情况下。

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。

如果你使用setHasStableIds(true)，你必须确保所有数据集项都有不同的id，否则可能会发生错误。

例如:

//This is our mock dataset which has FooItem type items
val dataset = listOf<FooItem>(items)

class FooItem {

    //here your variables

    private var id : Long = 0L

    //you can handle different ids at high accuracy like;
    fun getItemId() : Long {
        if (id == 0L) {
            id = abs(Random.nextLong(2, Long.MAX_VALUE))
        }
        return id
    }

}


//Then go back your adapter and set adapter item id below like
override fun getItemId(position: Int) = dataset[position].getItemId()

通过这种方式，你将不需要关闭recyclerview动画并通知所有数据集。

这是唯一的解决方案，对我来说，即使尝试了许多以上的解决方案。

1)。Intilization

CustomAdapter scrollStockAdapter = 
         new CustomAdapter(mActivity, new ArrayList<StockListModel>());
list.setAdapter(scrollStockAdapter);
scrollStockAdapter.updateList(stockListModels);

2)。在适配器中编写此方法

public void updateList(List<StockListModel> list) {
    stockListModels.clear();
    stockListModels.addAll(list);
    notifyDataSetChanged();
}

stockListModels ->这个列表是你在适配器中使用的。
