它与已知的android bug
类似有一种非常丑陋但又有效的方法
public class WrapContentLinearLayoutManager extends LinearLayoutManager {
//... constructor
@Override
public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
try {
super.onLayoutChildren(recycler, state);
} catch (IndexOutOfBoundsException e) {
Log.e("Error", "IndexOutOfBoundsException in RecyclerView happens");
}
}
}
mRecyclerView.setLayoutManager(new WrapContentGridLayoutManager(getContext(), spanCount));
对我而言,没有任何副作用。

此问题是RecyclerView的已知错误。最好的解决方案是,每次刷新RecyclerView之前清除列表。
要修复此问题,请在更新循环视图之前使用空列表调用notifyDataSetChanged()。
例如
//Method for refresh recycle view
if (!yourList.isEmpty())
yourList.clear(); //The list for update recycle view
adapter.notifyDataSetChanged();
答案 2 :(得分:4)
使用此选项刷新RecyclerView
items.clear(); //here items is an ArrayList populating the RecyclerView
adapter.notifyDataSetChanged();
items.addAll(list);// add new data
adapter.notifyItemRangeInserted(0, items.size);// notify adapter of new data
`

在我的无尽/分页RecyclerView
中快速滚动时遇到了这个问题。我的问题的根源来自于我在列表的开头有一个“标题”项,这个标题项不是数据源的一部分,它只是插入adapter
的开头名单。因此,当快速滚动并向RecyclerView
Adapter
添加新的项目页面并通知adapter
已插入新数据时,我没有考虑额外的标题项,从而使适配器列表的大小错误...并导致此异常......
简而言之,如果您在我们的RecyclerView
适配器中使用页眉/页脚,请确保在更新适配器数据时将其考虑在内。
示例:强>
public void addNewPageToList(List<MyData> list)
{ //
// Make sure you account for any header/footer in your list!
//
// Add one to the currentSize to account for the header item.
//
int currentSize = this.adapterList.size() + 1;
this.adapterList.addAll(list);
notifyItemRangeInserted(currentSize, this.adapterList.size());
}
修改强>
我想你总是可以使用适配器方法getItemCount()
来获取大小,而不是从“数据列表”中获取大小并添加它。您的getItemCount()
方法应该已经考虑了列表中的任何其他页眉/页脚/等。

在我的情况下,我这样做notifyItemInserted(position);
这引起了我这个问题然后我用它并且它完美地工作。notifyItemRangeInserted(startIndex,endIndex);

也许您可以在刷新适配器之前尝试以下操作:
dataList.clear();
patrolListAdapter.notifyDataSetChanged();

将此行与设置recyclerView一起放入。通过将RecyclerView的ItemAnimator设置为null可以解决此问题。
in kotlin
recyclerView.layoutManager = LinearLayoutManager(this)
recyclerView.itemAnimator = null

我有类似的问题。从RecyclerView中删除所有视图帮助了我:
RecyclerView.LayoutManager layoutManager = mRecyclerView.getLayoutManager();
layoutManager.removeAllViews();
答案 8 :(得分:0)
我遇到了同样的问题。 像这样重新创建新列表可以很好地解决问题:
适配器类中的
public void updateItems(List<ComponentEntity> newItems) {
List<ComponentEntity> updatedItems = new ArrayList<>();
updatedItems = newItems;
items = updatedItems;
notifyDataSetChanged();
}
答案 9 :(得分:0)
尝试将private List<Feed> mFeed;
更改为private ArrayList<Feed> mFeed;
然后在您的构造函数中将mFeed = feeds
更改为
public DataAdapter(List<Feed> feeds, RecyclerView recyclerView) {
mFeed.addAll(feeds);
...
然后您可以像这样正常添加:
public void addFeed(Feed feed) {
mFeed.add(feed);
notifyItemInserted(mFeed.size());
}
因此将List
更改为ArrayList
解决了我的问题。我认为是因为List
是一个抽象类,而add
,remove
,clear
等是方法,实际上并未在那里实现。因此,当您定义一个列表(private ArrayList<Feed> mFeed;
)并用另一个列表(mFeed = feeds
;来初始化它时,调用mFeed.add(feed)
不会执行任何操作,并导致recyclerView
引发异常。
答案 10 :(得分:0)
对我来说,问题是在实施增量搜索时数据集发生更改时我没有发布notifyDatasetChanged。
我有一个根据用户在搜索小部件中搜索的内容进行过滤的列表。对于列表中的每个项目,我都在发出远程请求,当我返回结果时,我正在更新该特定单元格。
为了使回收者视图正常工作,我必须同时进行通知
过滤原始数据集,然后发布数据集更改
this.searchResultTable?.post {
this.searchResultTable?.adapter?.notifyDataSetChanged()
}
收到回复后,再次发布通知
this.searchResultTable?.post {
this.searchResultTable?.adapter?.notifyItemChanged(index, updateDataHashMap)
}
您必须发布更新,而不是直接发送通知消息,以防止在布局布局之前更新出现时回收器视图崩溃。
另一个重要的陷阱是,当您在远程响应后发布各个更新时,必须确保用户当前看到的列表是发送请求时存在的列表。
答案 11 :(得分:0)
问题出在这行代码中:
mFeed = feeds;
您正在将mFeed
分配给调用者的实例feeds
,因此只要调用者对其变量进行更改(可能是添加,清除或删除项目),本地mFeed
就会更改
尝试更改为
mFeed.addAll(feeds);
别忘了将mFeed
初始化为符合您需求的列表mFeed = new ArrayList<>();

将此行与设置recyclerView一起放入。问题已由解决 将RecyclerView的ItemAnimator设置为null。
in kotlin
recyclerView.layoutManager = LinearLayoutManager(this)
recyclerView.itemAnimator = null
在Java中
recyclerView.setItemAnimator(null);
