RecyclerView：检测到IndexOutOfBoundsException不一致。无效的物料位置

Question

致命异常：检测到java.lang.IndexOutOfBoundsException不一致。无效的物料位置5（偏移量：5）。状态：24

这种撞车的情况太多了！！！

我在布料上弄到的。

DateList是涉及RecyclerView片段：

public class DateList extends Fragment {

DatesItemAdapter adapter;
List<DateItem2> keyList;
CardView cardView;
double v = 1;
float radius = 1;
ProgressBarCircular mCircular;
SwipeRefreshLayout swipeRefreshLayout;
RecyclerView mRecyclerView;
Animation animSlideUp;
Animation animSlideDown;
Uri.Builder builder;
JsonObjectRequest callToServerRequest;

public DateList() {

}

callToServer（带有假输入）首先清除键列表，然后填充它。几毫秒后，将调用callToServer（具有true输入）来再次清除keyList，并填充新项。这两个事件将在每次刷新中重复。

我根本找不出问题出在哪里！！！

这很可能是一个并发问题。我不知道JsonObjectRequest是如何工作的，但它的回调很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，回收器视图将尝试创建其信息不再存在的视图。

为了避免这种情况，一个可能的解决方案是将回调例程包装在一个Runnable中，由主线程中的处理程序调用。类似这样的事情：

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：清除列表后不需要调用notifyDataSetChanged。就在你填充它之后。
