Restarting Asynctask in fragment after using replace transaction

Restarting Asynctask in fragment after using replace transaction - android

I am using AsyncTask in my fragment for loading a list of data by Json. After clicking each list items this list fragment is replaced by details fragment containing details information. Then in new fragment (details fragment) user presses back button. Then again list fragment starts.
The problem is that Asynctask reloads again to fetch list items. I don't want this. I want to show previously loaded list. Here is the code:
public class MainList extends Fragment {
public MainList(){}
ArrayList<Country> countryList = new ArrayList<Country>();
Country country;
Button btnLoadMore;
ListView listView;
JSONParser jsonParser = new JSONParser();
public static String received_id;
// Creating JSON Parser object
JSONParser jParser = new JSONParser();
int current_page = 0;
int last_item;
int total_items = 32;
boolean continue_loading = true;
boolean loadingMore = false;
View footerView;
public ImageLoader_Json imageLoader;
int currentPosition = 0;
MyCustomAdapter dataAdapter = null;
private static String url_all_products_LoadMore = "http://www.hitel.ir/FarsiPlanet/Apps.php";
// JSON Node names
private static final String TAG_SUCCESS = "success";
private static final String TAG_PRODUCTS = "products";
private static final String TAG_PID = "pid";
private static final String TAG_NAME = "name";
private static final String TAG_RATE = "rate";
private static final String TAG_RATINGCOUNT = "ratingcount";
private static final String TAG_SHORT_DESCRIPTION = "short_description";
// products JSONArray
JSONArray products = null;
String Category;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

Category = getArguments().getString("category");
footerView= ((LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.loading_footer, null,false);
listView = (ListView) rootView.findViewById(R.id.listView1);
listView.addFooterView(footerView);

displayListView();
return rootView;

Here you need to include #Override before calling onScrollStateChanged and onScroll
listView.setOnScrollListener(new OnScrollListener() {
public void onScrollStateChanged(AbsListView view, int scrollState) {
// TODO Auto-generated method stub
}
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
int lastInScreen = firstVisibleItem + visibleItemCount;
if((lastInScreen == totalItemCount) && !(loadingMore)){
new loadMoreListView().execute();
}
}
});

when you perform the replace() action on the fragment, you are removing the list fragment , thus when tapping back, you are replacing the details fragment with your listfragment which invokes onCreateView() as part of the fragments lifecycle.
I would try to either keep a static booelan set to true when the asynctask's onPostExecute() ends, so the next time the list fragment's onCreateView() will be invoked , you would check the value of the flag and if set to true will not execute the task, but just set the adapter with the old static data.

First create a custom adapter implements filterable:
public class MyFilterableAdapter extends BaseAdapter implements Filterable {
private Context context;
private List<String> items;
private List<String> filteredItems;
private ItemFilter mFilter = new ItemFilter();
public MyFilterableAdapter(Context context, List<String> items) {
//super(context, R.layout.your_row, items);
this.context = context;
this.items = items;
this.filteredItems = items;
}
#Override
public int getCount() {
return filteredItems.size();
}
#Override
public Object getItem(int position) {
return filteredItems.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.row_search_merchant, parent, false);
viewHolder = new ViewHolder();
viewHolder.tvTitle = (TextView) convertView.findViewById(R.id.tv_title);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
String location = filteredItems.get(position);
if (!location.isEmpty() || viewHolder != null) {
viewHolder.tvTitle.setText(location);
}
return convertView;
}
public static class ViewHolder {
TextView tvTitle;
}
private class ItemFilter extends Filter {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
int count = items.size();
final List<String> tempItems = new ArrayList<>(count);
for (int i = 0; i < count; i++) {
if (items.get(i).toLowerCase().contains(filterString)) {
tempItems.add(items.get(i));
}
}
results.values = tempItems;
results.count = tempItems.size();
return results;
}
#SuppressWarnings("unchecked")
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredItems = (ArrayList<String>) results.values;
notifyDataSetChanged();
}
}
public Filter getFilter() {
return mFilter;
}
}
And than create a textwatcher
public class MyTextWatcher implements TextWatcher {
private MyCustomAdapter lAdapter;
public MyTextWatcher(MyCustomAdapter lAdapter) {
this.lAdapter = lAdapter;
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void afterTextChanged(Editable s) {
lAdapter.getFilter().filter(s.toString().toLowerCase());
}
}
And finally add your TextWatcher to your Search Edit Text:
final MyCustomAdapter lAdapter = new MyCustomAdapter(context, items);
EditText etSearch = (EditText) view.findViewById(R.id.et_search);
etSearch.addTextChangedListener(new SearchTextWatcher(lAdapter));
I hope this'll help you.

I want load more 7 pages

In your LoadData AsyncTask, in onPostExecute, you always re-create the adapter with new data received, so it does not append the existing data.
What you need to do is add a method to InfoTeacher adapter to append new items to your existing data, and then call that method from onPostExecute if the adapter already exists (adapter != null).

Listadapter duplicating items in listview after each time asynctask starts

I have a listview in fragment. It loads data from Json. After clicking list items a fragment transaction begins (replace). By pressing back button (in new fragment) again list fragment appears but the problem is that:
1: It loads again Asynctask (that I don't want it).
2. It adds new items on top of the former items in the list. You can say duplication in listview items happens. Each time I click listview item abd then return back to listview fragment it adds the same items to the end of the list. My code is this:
public class Followed extends Fragment {
public Followed(){}
ArrayList<Country> countryList = new ArrayList<Country>();
Country country;
ListView listView;
JSONParser jsonParser = new JSONParser();
public static String received_id;
// Creating JSON Parser object

ListView shows wrong placement of images taken from URL

My listview doesn't show exact placement of images on its individual custom adapters. I am trying to load the images using AsyncTask. Sometimes the images duplicates and I don't have any idea why. Here is my ArrayAdapter code:

ImageView imageView;

LoadImage loadImg;
}
#Override

How to start a new activity form ListView and give it multiple parameters

Below is my code which displays data in listview which is parses from json.
I want to start new activity when the user clicks on any item in the list.
I followed this url http://www.androidhive.info/2012/01/android-json-parsing-tutorial/ and this is the json file http://api.androidhive.info/contacts/
How to start a new activity when a user clicks on any item in listview and pass the remaining json values as parameters?
Now my listview shows only names but i want to pass the remaining items, such as email, gender & mobile to the other activity.

startActivity(i);
}
});
can see this also
http://www.ezzylearning.com/tutorial.aspx?tid=1351248
and
http://www.bogotobogo.com/Android/android6ListViewSpinnerGridViewGallery.php

You start an activty with startActivity(intent);
You set the OnClickListner on your ListView which is not included in your code so Im implying:
OnItemClickListener listener = new OnItemClickListener (){
#Override
onItemClick(AdapterView<?> parent, View view, int position, long id){
String name = ((TextView) view.findViewById(R.id.txtText)).getText();
Intent intent = new Intent(context,WhatEverYouWant.class);
intent.putExtra("name",name);
startActivity(intent);
}
}
ListView listView = getView().findViewById(R.id.listview);
listView.setOnItemClickListener (listener);

I thing you shold put objJson.getString(NAME); after onItemClick...... to take the clicked item string name not other item
