【中文标题】RecyclerView：检测到 IndexOutOfBoundsException 不一致。无效的项目位置【英文标题】：RecyclerView: IndexOutOfBoundsException Inconsistency detected. Invalid item position 【发布时间】：2017-09-30 20:04:58 【问题描述】：致命异常：检测到 java.lang.IndexOutOfBoundsException 不一致。无效的项目位置 5(offset:5).state:24
这种崩溃发生的太多了！！！
我在 Fabric Crashlytics 中得到它。
致命异常：java.lang.IndexOutOfBoundsException：不一致 检测到。无效的项目位置 5(offset:5).state:41 在 android.support.v7.widget.RecyclerView$Recycler.clear（未知来源） 在 android.support.v7.widget.GapWorker.add（未知来源） 在 android.support.v7.widget.GapWorker.add（未知来源） 在 android.support.v7.widget.GapWorker.remove（未知来源） 在 android.support.v7.widget.GapWorker.add（未知来源） 在 android.support.v7.widget.GapWorker.run（未知来源） 在 android.os.Handler.handleCallback(Handler.java:739) 在 android.os.Handler.dispatchMessage(Handler.java:95) 在 android.os.Looper.loop(Looper.java:135) 在 android.app.ActivityThread.main(ActivityThread.java:5930) 在 java.lang.reflect.Method.invoke(Method.java) 在 java.lang.reflect.Method.invoke(Method.java:372) 在 com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1405) 在 com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1200)
DateList是涉及RecyclerView的Fragment：

我尝试了其他一些解决方案，例如 THIS 和 THIS 和 THIS，但它们并没有解决我的问题。我认为我的问题与其他人不同，因为我在每次通话中都会清除我的列表。
我根本找不到问题所在！！！
【问题讨论】：
请问您是如何确定哪个 RecyclerView 是问题的根源？我和你在同一条船上，但我不知道应该归咎于哪个班级。 @JasonRobinson ：我有同样的问题，但我猜这个 RecyclerView 会导致崩溃！因为所有用户在每次使用时都会查看这个Fragment，而其他RecyclerViews在一些不太常见的Activity和Fragment中。 您的问题是重复的。检查以下问题：***.com/questions/26827222/… @dowookim 是的，但前一个是由于 RecyclerView 中的错误导致的，并且接受的解决方案不再有效。这个问题现在真的需要一个不同的答案 由于这个问题已经快3年了，甚至不清楚使用的是哪个版本。代码很乱，并且没有任何适当的堆栈跟踪；不会碰那个。 GitHub 上的minimal 示例应用程序可能有助于重现问题 - 并获得可靠的答案。 【参考方案1】：这可能是一个并发问题。我不知道 JsonObjectRequest 是如何工作的，但它的回调可能是在后台线程中调用的。因此，当您在更新数据时滚动时，回收器视图会尝试创建其信息不再存在的视图。
为了避免这种情况，一种可能的解决方案是将回调例程包装在 Runnable 中，以便由主线程中的 Handler 调用。像这样的：
public void callToServer(final boolean rTime)
String url = builder.toString();
if (rTime)
url = url + "&rTime=1";
else
url = url + "&rTime=0";
final Handler handler = new Handler(getMainLooper());
callToServerRequest = new JsonObjectRequest(Request.Method.GET
, url
, null
, new Response.Listener<JSONObject>()
@Override
public void onResponse(JSONObject response)
handler.post(new Runnable()
@Override
public void run()
try
JSONArray array = new JSONArray(response.getString("Ticks"));
// Clears list to replace new list items
keyList.clear();
adapter.notifyDataSetChanged();
for (int i = 0; i < array.length(); i++)
JSONObject obj = new JSONObject(array.get(i).toString());
DateItem2 item = new DateItem2();
item.setAvailable(obj.getString("available"));
item.setType(obj.getString("type"));
item.setUrl(obj.getString("url"));
item.setTime(obj.getString("time"));
item.setDescription(obj.getString("description"));
keyList.add(item);
if (rTime)
mCircular.setVisibility(View.GONE);
adapter.notifyDataSetChanged();
mRecyclerView.setVisibility(View.VISIBLE);
swipeRefreshLayout.setRefreshing(false);
catch (JSONException e)
e.printStackTrace();
if (!rTime)
callToServer(true);
);
, new Response.ErrorListener()
@Override
public void onErrorResponse(VolleyError volleyError)
handler.post(new Runnable()
@Override
public void run()
if (rTime)
mCircular.setVisibility(View.GONE);
try
if (ConnectionDetector.IS_CONNECTED(getActivity()))
if (volleyError.toString().contains("[]") && !rTime)
callToServer(true);
catch (Exception e)
e.printStackTrace();
swipeRefreshLayout.setRefreshing(false);
);
);
AppController.getInstance().addToRequestQueue(callToServerRequest, "DateList" + "callToServerRequest");
PS：清除列表后无需调用 notifyDataSetChanged。就在你填充它之后。
【讨论】：
感谢您的回答。我会试试看。但需要一段时间才能确定它是否有效。 @Kevin 我仍然无法拒绝或接受此解决方案，因为我从未在自己的设备上遇到过这种崩溃。我只在 Firebase Crashlytics 控制台收到此崩溃报告。所以我不得不发布一个新版本，期待它的反馈。 一个好的测试用例是使用一台旧设备并在后台运行许多应用程序。而且，更重要的是，列表必须充满项目，越多越好。尝试在更新列表时滚动列表。 没用！我仍然收到java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positiona2fd6b8b position=9 id=-1, oldPos=-1, pLpos:-1 no parent【参考方案2】：
为我工作！
这是一个常见的问题，当您尝试在列表中添加数据时。
尝试按照以下步骤操作：
1 - 清除您的列表
2 - 通知您的适配器
3 - 将数据添加到您的列表中
4 - 通知适配器
【讨论】：
【参考方案3】：将您的布局管理器更改为 WrapContentLinearLayoutManager，这将解决问题。
public class WrapContentLinearLayoutManager extends LinearLayoutManager
public WrapContentLinearLayoutManager(Context context)
super(context);
public WrapContentLinearLayoutManager(Context context, int orientation, boolean reverseLayout)
super(context, orientation, reverseLayout);
public WrapContentLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes)
super(context, attrs, defStyleAttr, defStyleRes);
//... constructor
@Override
public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state)
try
super.onLayoutChildren(recycler, state);
catch (IndexOutOfBoundsException e)
LogUtils.debugMsg("probe" + "meet a IOOBE in RecyclerView");
@Override
public boolean supportsPredictiveItemAnimations()
return false;
【讨论】：
你能解释一下你提供的解决方案吗？ 我不知道这个解决方案是如何工作的，但它对我有用 你得到的正是IndexOutOfBoundsException 吗？
是的，我遇到了同样的错误，也尝试了 Diff utils，但最后我用这个布局管理器修复了
这个问题表明这个解决方案有助于减少崩溃的数量，但并没有完全消除它：***.com/q/41300626/1101730【参考方案4】：
我只是通过从LinearLayoutManager 中删除对预测项目动画的支持来解决此问题：
import android.content.Context
import android.util.AttributeSet
import androidx.recyclerview.widget.LinearLayoutManager
class CustomLinearLayoutManager @JvmOverloads constructor(
context: Context?,
attrs: AttributeSet? = null,
defStyleAttr: Int = 0
) : LinearLayoutManager(context, attrs, defStyleAttr, defStyleAttr)
override fun supportsPredictiveItemAnimations() = false
如果您需要水平方向，请使用
init
orientation = HORIZONTAL
【讨论】：
我不确定我要说什么，因为您在 Kotlin 中实现了它，但看起来您的代码与 Kashyap 的代码相似，但我看到您在他/她的帖子下发表了评论该解决方案将在一定程度上减少崩溃，但不会归零。我有一些疑问。你能用Java写吗？接下来的问题是，你的代码和 Kashyap 的代码有什么区别？你的代码能完全解决问题吗？您是否在许多用户使用的应用程序中尝试过此解决方案？ @AlirezaNoorali 不同之处在于不需要在onLayoutChildren 中添加try-catch，因为永远不会抛出异常（至少在我的情况下）。自从我关闭了预测项目动画后，我没有遇到任何崩溃，但根据***.com/q/41300626/1101730，仍然可能有一些崩溃。我将在下周将其推送给成千上万的用户，让我们拭目以待。
这样我们会有一个很好的测试。请在此处与我们分享此实验的结果。
@AlirezaNoorali 看起来这确实修复了崩溃，一个月后我可以说它不再发生了。
