Dynamic listview save state - android

I am working on laundry app. I have a listview (Fragment) like this so user can select the items.
My Problem is when I click the continue and then I come back to this screen again its value become zero. How can I save listview state.
I tried this code in my fragment but no luck. And also try save and restore instance state method but facing same problem.
// Save the ListView state (= includes scroll position) as a Parceble
Parcelable state = listView.onSaveInstanceState();
// e.g. set new items
listView.setAdapter(adapter);
// Restore previous state (including selected item index and scroll position)
listView.onRestoreInstanceState(state);

When used custom adapter always try to implement ViewHolder design pattern for ListView performance and use custom filter function instead Filterable implementation :
Custom filter funcation required two array list one is filterable data list and another one is for orignal data list :
public void filter(String constraint) {
filterData.clear();
if (constraint.length() == 0) {
filterData.addAll(orignalData);
}else{
for (HashMap<String,String> row: orignalData) {
if(row.get(Cardiology_updates.UpdateTitle).toUpperCase().startsWith(constraint.toString().toUpperCase())){
filterData.add(row);
}
}
}
notifyDataSetChanged();
}
Example :
et.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable arg0) {
adapter.filter(arg0.toString());
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1,int arg2, int arg3) {
}
#Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,int arg3) {
}
});
public class UpdatesAdapterList extends BaseAdapter {
private Context context;
private ArrayList<HashMap<String,String>> filterData;
private ArrayList<HashMap<String,String>> orignalData;
public ImageLoader imageLoader;
public UpdatesAdapterList(Context context,ArrayList<HashMap<String, String>> orignalData) {
this.context = context;
this.orignalData = orignalData;
filterData = new ArrayList<HashMap<String,String>>();
filterData.addAll(this.orignalData);
imageLoader = new ImageLoader(this.context);
}
#Override
public int getCount() {
return filterData.size();
}
#Override
public Object getItem(int position) {
return filterData.get(position);
}
#Override

return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {

Hello i have made a dynamic listview..Now i want to add filter in listview.if i enter text in edittext then item which mathces the search should display..have called addTextChangedListener to my edittext..and called a method filter in my adapter..but m not getting any idea what should i write in my filter method as it is a dynamic listview...

You need to implement Filterable interface in your UpdatesAdapterList class.
For detailed explanation visit How to implement getfilter() with custom adapter that extends baseadapter?.
public class UpdatesAdapterList extends BaseAdapter implements Filterable {
...
#Override
public Filter getFilter(){
// Your Search logic goes here..
Filter filter = new Filter() {
FilterResults results;
ArrayList<HashMap<String, String>> filteredList;
#Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
// Has the filtered values
data = (ArrayList<HashMap<String, String>>) results.values;
notifyDataSetChanged();
}
#Override
protected FilterResults performFiltering(CharSequence constraint) {
// Holds the results of a filtering operation in values
results = new FilterResults();
filteredList= new ArrayList<HashMap<String, String>>();
//This is the search string user typed in EditText.
String searchString = constraint.toString();
/*
* Code to update the filteredList based on Search String.
*
* I'm just writing pseudo code for search, based on
* Cardiology_updates.UpdateTitle
*/
int mCount=data.size();
for (int i = 0; i < mCount; i++) {
HashMap<String, String> obj= data.get(i);
String updateTitle=obj.get(Cardiology_updates.UpdateTitle);
if(updateTitle.contains(searchString)){
filteredList.add(obj);
}
}
synchronized (this) {
// set the Filtered result to return
results.count = filteredList.size();
results.values = filteredList;
}
}
return results;
}
};
return filter;
}
}

I've got a functioning Universal Image Loader that I'm trying to switch to grabbing the image URLs from JSON rather than the Constants Class that it normally uses. I've created a JSON Parsing Class that outputs an ArrayList called galleryArrList. But I can't figure out how to implement my JSON Parsing class and also how to modify the Adapter class in the UILGrid class to accept the galleryArrList String. Here are the Classes:
UILGrid Class:
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import com.nostra13.universalimageloader.core.DisplayImageOptions;
import com.mysite.wcbc.UKVPConstants.Extra;
public class UILGrid extends AbsListViewBaseActivity {
String[] imageUrls;
DisplayImageOptions options;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.uil_grid);
Bundle bundle = getIntent().getExtras();
imageUrls = bundle.getStringArray(Extra.IMAGES);
options = new DisplayImageOptions.Builder()
.showImageOnLoading(R.drawable.ic_stub)
.showImageForEmptyUri(R.drawable.ic_empty)
.showImageOnFail(R.drawable.ic_error).cacheInMemory(true)
.cacheOnDisc(true).bitmapConfig(Bitmap.Config.RGB_565).build();
listView = (GridView) findViewById(R.id.uil_gridview);
((GridView) listView).setAdapter(new ImageAdapter());
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
startImagePagerActivity(position);
}
});
}
private void startImagePagerActivity(int position) {
Intent intent = new Intent(this, CVP2.class); // ---- Change here
intent.putExtra(Extra.IMAGES, imageUrls);
intent.putExtra(Extra.IMAGE_POSITION, position);
startActivity(intent);
}
public class ImageAdapter extends BaseAdapter {
#Override
public int getCount() {
return imageUrls.length;
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final ImageView imageView;
if (convertView == null) {
imageView = (ImageView) getLayoutInflater().inflate(
R.layout.uil_grid_item, parent, false);
} else {
imageView = (ImageView) convertView;
}
imageLoader.displayImage(imageUrls[position], imageView, options);
return imageView;
}
}
}
my UILJSONParse Class:
import java.util.ArrayList;
import java.util.HashMap;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.os.AsyncTask;
public class UILJSONParse extends AsyncTask<String, String, JSONObject> {

// Hashmap for ListView

private static final String TAG_GALLERYURL = "galleryurl";
private static final String TAG_ID = "id";
private static final String TAG_GALLERYDESCR = "gallerydescr";
// gallery JSONArray

#Override

// Creating JSON Parser instance
JGrid4Adapter jParser = new JGrid4Adapter();
// getting JSON string from URL
JSONObject jsonOb = jParser.getJSONFromUrl(url);
return jsonOb;
}
#Override
protected void onPostExecute(JSONObject jsonOb) {
try {
JSArrGallery = jsonOb.getJSONArray(TAG_GALLERY);
// looping through All gallery images
for (int i = 0; i < JSArrGallery.length(); i++) {
JSONObject galleryJO = JSArrGallery.getJSONObject(i);
String idStr = galleryJO.getString(TAG_ID);
String urlStr = galleryJO.getString(TAG_GALLERYURL);
String descrStr = galleryJO.getString(TAG_GALLERYDESCR);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_ID, idStr);
map.put(TAG_GALLERYURL, urlStr);
map.put(TAG_GALLERYDESCR, descrStr);
// adding HashMap map to ArrayList galleryArrList, defined
// above
galleryArrList.add(map);
}// -- END for loop
} catch (JSONException e) {
e.printStackTrace();
}// --- END Try
}// --- END onPostExecute
}// --- END UILJSONParse Class

I've figured this out since asking the question. I have a Button Interface Activity where an AsyncTask is called that grabs the JSON data when a button is clicked. The AysncTask then bundles the data and sends it to my Gallery Grid Class. The AsyncTask is calling the above JSON Parsing Class. So here's the code:
// --- artwork button
cartoon_BTN.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
jsonFileStr = "artwork_json";
new ArtworkJSON().execute();
}
});
// --- end artwork button
private class ArtworkJSON extends AsyncTask<Void, Void, Void> {
JSONObject jsonobject;
String TAG_ID = "id";
String TAG_DESCR = "artworkdescr";
String TAG_MEDIUM = "artworkmedium";
String TAG_PRICE = "artworkprice";
String TAG_URL = "artworkurl";

I am able to display all data date wise location wise and ....together But i want to Filter data -date wise location means if we check in location wise then it should Print location Only if filter date wise it should display date ..in list please help i have tired much But unable to do this....i have create check Box for select option date wise filter , location wise filter so please check my code if u want i can send complete code .

If you are using EditText to search then you have to write your own filter method..here is an example Custom ListView Search .
you have to change filter method something like this.
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
worldpopulationlist.clear();
if (charText.length() == 0) {
worldpopulationlist.addAll(arraylist);
} else {
for (WorldPopulation wp : arraylist) {
if(isDate)
{
if (wp.getDate().toLowerCase(Locale.getDefault()).contains(charText))
{
worldpopulationlist.add(wp);
}
}else{
if(wp.getLocation().toLowerCase(Locale.getDefault()).contains(charText))
{
worldpopulationlist.add(wp);
}
}
}
}
notifyDataSetChanged();
}

The short version of my question: If I have a listview where each item has a button and that button causes a textview on that listitem to be updated, how do I make changes I make to the list row from a onClickListener in getView permanent?
Detailed description of problem: I have a listview and that listview has a "bump" button (equivalent to a "like" button on Facebook) and when a user presses this like button 3 things happen:
A async request is made to my api which records the "bump" by adding a record to one of my db tables. If the request is successful the api issues a response with 2 fields ( is_bumped(boolean) & bump_count(int) )
If the api request was successful then we grab bumpCount from the response and use it to update the bumpTv to reflect the new total number of times that list item has been "bumped".... example: "3 Bumps"
If the API request was successful and isBumped=true then we update the image resource to a version of my bump icon that looks selected/pressed.
All of this works just fine at first glance, but if you "bump" a list item and then scroll all the way to the bottom of the list and then back to the top, the list item you just bumped will no longer appear to be bumped unless you refresh the entire activity. I know this has to have something to do with the data that I bind to the adapter not being updated, but how do I go about updating without refreshing the entire update?

EDIT: After taking the advice in the comments i was sure my list would begin functioning the way I had intended it to , but it only opened up a whole new can of hell....now for some reason if a user clicks the "bump" button anywhere in the first 6 items it works just fine, but beyond that something weird starts happening. when a user hits the bump button on one of the list items below the first 6 items it sends the wrong position and its a position somewhere between 0 and 6 ?!?!?

In the question's comments, it was established that even though the UI was being updated (based on user interaction), the underlying data used by adapter's getView() weren't.
Solution: Update the data source and call notifyDataSetChanged() on the adapter. Let getView() handle UI updates.
Read through the comments for more information.
