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。

如果有多个回收器视图共享同一个适配器，则会弹出此错误，因此为了避免此错误，将为这些回收器视图创建单独的适配器。 这使得回收器视图具有非共享池，从而在不需要时停止适配器来填充它们。

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.

我有一个(可能)相关的问题-进入一个新的实例的活动与RecyclerView，但与一个较小的适配器触发这个崩溃为我。

RecyclerView.dispatchLayout()可以在调用mrecycle . clearoldpositions()之前尝试从废品中提取项目。结果是从公共池中提取位置高于适配器大小的项。

幸运的是，它只这样做，如果PredictiveAnimations启用，所以我的解决方案是子类GridLayoutManager(线性layoutmanager有同样的问题和“修复”)，并覆盖supportpredictiveitemanimations()返回false:

/**
 * No Predictive Animations GridLayoutManager
 */
private static class NpaGridLayoutManager extends GridLayoutManager {
    /**
     * Disable predictive animations. There is a bug in RecyclerView which causes views that
     * are being reloaded to pull invalid ViewHolders from the internal recycler stack if the
     * adapter size has decreased since the ViewHolder was recycled.
     */
    @Override
    public boolean supportsPredictiveItemAnimations() {
        return false;
    }

    public NpaGridLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    public NpaGridLayoutManager(Context context, int spanCount) {
        super(context, spanCount);
    }

    public NpaGridLayoutManager(Context context, int spanCount, int orientation, boolean reverseLayout) {
        super(context, spanCount, orientation, reverseLayout);
    }
}

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。

在我的例子中，我在一个非ui线程中更新项目并调用notifyDataSetChanged。大多数时候它是有效的，但当大量变化迅速发生时，它就会崩溃。当我这样做的时候，基本上

activity.runOnUiThread(new Runnable() {
    @Override
    public void run() {
        changeData();
        notifyDataSetChanged();
    }
});

然后它停止了崩溃。

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。
