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。

扩展LinearLayoutManager并捕获这个错误

public class NoCrashLinearLayoutManager extends LinearLayoutManager {

    public NoCrashLinearLayoutManager(Context context) {
        super(context);
    }

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

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

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
        try {
            super.onLayoutChildren(recycler, state);
        } catch (IndexOutOfBoundsException e){
            e.printStackTrace();
        }
    }
}

我以前也遇到过同样的问题。终于找到解决办法了

我所做的是通知适配器，该项目已删除，然后通知适配器数据集范围改变

 public void setData(List<Data> dataList) {
      if (this.dataList.size() > 0) {
          notifyItemRangeRemoved(0, dataList.size());
          this.dataList.clear();
      }
      this.dataList.addAll(dataList)
      notifyItemRangeChanged(0, dataList.size());

 }

为了解决这个问题，只需在更新循环视图之前调用notifyDataSetChanged()，使用空列表。

例如

//Method for refresh recycle view

    if (!hcpArray.isEmpty())

hcpArray.clear();//更新循环视图列表

adapter.notifyDataSetChanged();

我有同样的问题与RecyclerView 因此，我只是在列表清除后立即通知适配器有关数据集的更改。

mList.clear();
mAdapter.notifyDataSetChanged();

mList.addAll(newData);
mAdapter.notifyDataSetChanged();

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。

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);
    }
}
