我正在调用API从服务器获取双方数据并将数据添加到RecyclerView但是每当我快速滚动时我都会收到错误
java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 0(offset:0).state:10
几天前工作正常，所以我觉得这是RecyclerView的问题。只有在向下滚动后向上滚动时才会出现此问题。
我使用RecyclerView的滚动侦听器作为
//Scroll Listener
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
totalItemCount = mLayoutManager.getItemCount();
lastVisibleItem = mLayoutManager.findLastCompletelyVisibleItemPosition();
if (!loading && totalItemCount <= (lastVisibleItem + visibleThreshold) && customersList.size() > 0) {
// End has been reached
// Do something
loading = true;
//calling API
if (!NetworkUtil.getConnectivityStatusString(getActivity()).equals(getString(R.string.not_connected_to_internet))) {
getCustomersList(customersList.get(totalItemCount - 1).getCreatedTs(), "2"
, customerDetailSearchEditText.getText().toString().trim());
} else {
if (swipeRefreshLayout.isRefreshing()) {
swipeRefreshLayout.setRefreshing(false);
}
Toast.makeText(getActivity(), getString(R.string.network_error), Toast.LENGTH_SHORT).show();
}
}
}
});
我将RecyclerView的API和更新适配器称为
try {
if (apiResponse.getSuccess()) {
for (Customers customers : apiResponse.getData().getCustomers()) {
if (apiResponse.getData().getCustomers() != null) {
if (traversalValue.equals("2")) {
customersList.add(customers);
dataChanged = "yes";
} else if (traversalValue.equals("1")) {
if (swipeRefreshLayout != null && swipeRefreshLayout.isRefreshing()) {
// To remove duplicate items
if (!time.equals(customers.getCreatedTs())) {
customersList.add(0, customers);
}
} else {
customersList.add(customers);
}
dataChanged = "yes";
}
}
}
loading = false;
}
if (customersList != null && customersList.size() == 0) {
textViewEmptyView.setVisibility(View.VISIBLE);
swipeRefreshLayout.setVisibility(View.GONE);
} else {
textViewEmptyView.setVisibility(View.GONE);
swipeRefreshLayout.setVisibility(View.VISIBLE);
}
if (sortValue != 0) {
bottomLayout.setVisibility(View.VISIBLE);
if (sortValue == 1 || sortValue == 2) {
//Sorted
sortSpannable = new SpannableString("Sorted by : ");
sortSpannable.setSpan(new RelativeSizeSpan(1.2f), 0, 9, 0); // set size
sortTextView.setText(sortSpannable);
if (sortValue == 1) {
sortedBySpannable = new SpannableString("Amount(Asc)");
} else {
sortedBySpannable = new SpannableString("Amount(Desc)");
}
sortTextView.append(sortedBySpannable);
} else if (sortValue == 3 || sortValue == 4) {
//Sorted
sortSpannable = new SpannableString("Sorted by : ");
sortSpannable.setSpan(new RelativeSizeSpan(1.2f), 0, 9, 0); // set size
sortTextView.setText(sortSpannable);
if (sortValue == 3) {
sortedBySpannable = new SpannableString("Name(A-Z)");
} else {
sortedBySpannable = new SpannableString("Name(Z-A)");
}
sortTextView.append(sortedBySpannable);
}
} else {
bottomLayout.setVisibility(View.GONE);
}
if (swipeRefreshLayout != null && swipeRefreshLayout.isRefreshing()) {
swipeRefreshLayout.setRefreshing(false);
}
if (traversalValue.equals("2")) {
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
customerMainFragmentAdapter.notifyDataSetChanged();
}
});
if (dataChanged != null && dataChanged.equals("yes")) {
// recyclerView.smoothScrollToPosition(customerMainFragmentAdapter.getItemCount() + 1);
}
} else if (traversalValue.equals("1")) {
if (dataChanged != null && dataChanged.equals("yes")) {
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
customerMainFragmentAdapter.notifyDataSetChanged();
recyclerView.smoothScrollToPosition(0);
}
});
}
}
} catch (Exception e) {
e.printStackTrace();
if (swipeRefreshLayout != null && swipeRefreshLayout.isRefreshing()) {
swipeRefreshLayout.setRefreshing(false);
}
}

我已经搜索过它并尝试了许多解决方案。我的源代码的差异是
ArrayList上添加数据，以便刷新。RecyclerView的末尾。因此，我们无法在此处清除ArrayList。希望我已经正确地解释了我的问题，你们会帮助我。感谢。
答案 0 :(得分：1)
我认为当您在适配器中调用recyclerView.smoothScrollToPosition(0)时，会再次调用侦听器的onScrolled方法，因为您过早地将加载设置为false并且您的recycleView尚未更新。
我建议您在平滑滚动到位置后设置loading = false。或者你可以打电话给recyclerLog.scrollTo(0)并跳过整个过程。
