question:Q:.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification android I am using AyncTask to get data from server and set it to listview. For notifying the changes to the listview I am calling mAdapter.notifyDataSetChanged(); in onPostExecute() method I am using Pull to refresh listview library Still I am getting IllegalStateException listView.setOnScrollListener(new OnScrollListener() { @Override public void onScrollStateChanged(AbsListView view, int scrollState) { } @Override public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) { int count = Integer.parseInt(index_temp)+6; System.out.println(Checking + listView.getLastVisiblePosition()); System.out.println(----->Checking loadmore:+ load_more); System.out.println(----->Checking actual:+ count); if (listView.getLastVisiblePosition()+1 == count) { if(load_more==1){ index_temp = String.valueOf(Integer.parseInt(icount) + Integer.parseInt(index_temp)); new GetList_ontouch().execute(index_temp); } } } }); GetList_ontouch private class GetList_ontouch extends AsyncTask<String, Void, Void> { @Override protected void onPreExecute() { super.onPreExecute(); progressBar1.setVisibility(0); } @Override protected Void doInBackground(String... params) { if (NetworkCheck.isNetworkAvailable(getActivity()) == true) { Log.d(index count for array, params[0]); if(Integer.parseInt(params[0])==0){ Log.d(index count for array,Reached); newsList = new ArrayList<HashMap<String, String>>(); } // Creating service handler class instance ServiceHandler sh = new ServiceHandler(); // Making a request to url and getting response String jsonStr = sh.makeServiceCall(All_link.HOME_DATA_URL + /+params[0]+/+ icount, ServiceHandler.GET); Log.d(Response: , > + jsonStr); if (jsonStr!= null) { try { JSONObject jsonObj = new JSONObject(jsonStr); // Getting JSON Array node news = jsonObj.getJSONArray(All_link.TAG_NEWS); String err = jsonObj.getString(All_link.TAG_ERROR); String more = jsonObj.getString(All_link.TAG_MORE); Log.e(------>Error,String.valueOf(err)); Log.e(------>More,String.valueOf(more)); if(more.equals(0)){ load_more = 0; }else{ load_more = 1; } // looping through All Contacts for (int i = 0; i < news.length(); i++) { JSONObject segments_list = news.getJSONObject(i); for (int plates_count = 0; plates_count < segments_list .length(); plates_count++) { String plates = ; if (plates_count == 3) { plates = String.valueOf(banner_image); JSONObject segments_plates = segments_list .getJSONObject(plates); //String flag = banner_image; String id = segments_plates .getString(All_link.TAG_BANNER_ID); String banner_no = segments_plates .getString(All_link.TAG_BANNER_NO); String banner_image; if(segments_plates.getString(All_link.TAG_BANNER_THUMB_URL)==){ banner_image = All_link.TAG_NO_IMAGE; }else{ banner_image = segments_plates.getString(All_link.TAG_BANNER_THUMB_URL); } String banner_status = segments_plates .getString(All_link.TAG_BANNER_STATUS); // tmp hashmap for single news HashMap<String, String> news_hashmap = new HashMap<String, String>(); // adding each child node to HashMap key => // value news_hashmap.put(All_link.TAG_BANNER_ID, id); news_hashmap.put(All_link.TAG_BANNER_NO, banner_no); news_hashmap.put(All_link.TAG_BANNER_THUMB_URL, banner_image); news_hashmap.put(All_link.TAG_BANNER_STATUS, banner_status); /*news_hashmap .put(All_link.TAG_BANNER_FLAG, flag);*/ // adding contact to contact list //newsList.add(news_hashmap); addSeparatorItem(); } else { plates = String.valueOf(plates_count + 1); JSONObject segments_plates = segments_list .getJSONObject(plates); if(segments_plates.getString(All_link.TAG_NEWS_TYPE).equals(2)){ //type_of_news = segments_plates.getString(All_link.TAG_NEWS_TYPE); addSeparatorItem_for_live(); } String id = segments_plates .getString(All_link.TAG_ID); String news_title = segments_plates .getString(All_link.TAG_NEWS_TITLE); String news_desc = segments_plates .getString(All_link.TAG_DESC); String segment = segments_plates .getString(All_link.TAG_SEGMENT); String plate = segments_plates .getString(All_link.TAG_PLATE); String img =; if(segments_plates.getString(All_link.TAG_THUMB_URL).equals()){ img = All_link.TAG_NO_IMAGE; }else{ img = segments_plates.getString(All_link.TAG_THUMB_URL); } HashMap<String, String> news_hashmap = new HashMap<String, String>(); // adding each child node to HashMap key => // value news_hashmap.put(All_link.TAG_ID, id); news_hashmap.put(All_link.TAG_NEWS_TITLE, news_title); news_hashmap.put(All_link.TAG_DESC, news_desc); news_hashmap.put(All_link.TAG_SEGMENT, segment); news_hashmap.put(All_link.TAG_PLATE, plate); news_hashmap.put(All_link.TAG_THUMB_URL, img); //news_hashmap.put(All_link.TAG_BANNER_FLAG, flag); // adding contact to contact list newsList.add(news_hashmap); int val = 0; int val2 = 1; val = (Integer.parseInt(segment)%2)==0?

A: Don't recreate your adapter each time doInBackground is call mAdapter = new MyCustomAdapter(getActivity(), newsList); listView.setAdapter(mAdapter); Create it once and for all somewhere relevant. mAdapter = new MyCustomAdapter(getActivity(), new ArrayList<HashMap<String, String>>()); listView.setAdapter(mAdapter); And then return the List in doInBackground return newsList; And change onPostExecute like this, to integrate results in the adapter. onPostExecute runs in UI thread and has been designed to handle that kind of operation, like updating an adapter. @Override protected void onPostExecute(List<HashMap<String, String>> result) { // Assuming here MyCustomAdapter is an ArrayAdapter mAdapter.clear(); mAdapter.addAll(result); mAdapter.notifyDataSetChanged(); // [...] } The AsyncTask would look like this : private class GetList_refresh extends AsyncTask<String, String, List<HashMap<String, String>>> Instead of recreating the adapter each time, where should you create it once?

question:Your response should contain at least 3 sentences. The response must have 2 sections. Mark the beginning of each section with Section X, such as: Section 1. In your response, the word important should appear at least 3 times. Include a postscript starting with P.S.

question:Create a Python function to generate a list of feature names based on a list of words and a list of numbers. The feature names should follow the convention of concatenating the words in the first list with the numbers in the second list. The order of the words in the feature names should correspond to the order of the words in the first list. For example, given `words = ['a', 'b', 'c']` and `numbers = [1, 2, 3]`, the function should return `['a1', 'b2', 'c3']`.
