android JSON upload images collection dose not work

I'm trying to upload some of images after selecting it from my UploadActivity.
public static int count;
private Bitmap[] thumbnails;
private boolean[] thumbnailsselection;

setContentView(R.layout.activity_upload);
msgLoading = (TextView) findViewById(R.id.msgLoading);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override

GridView imagegrid = (GridView) findViewById(R.id.PhoneImageGrid);
imageAdapter = new ImageAdapter();
imagegrid.setAdapter(imageAdapter);
imagecursor.close();
msgLoading.setVisibility(View.GONE);
}
},100);
final Button uploadBtn = (Button) findViewById(R.id.uploadDONE);
uploadBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
final int len = thumbnailsselection.length;
int cnt = 0;
String selectImages = "";
for (int i = 0; i < len; i++) {

IPath.add(selectImages);
}
}

} else {

public class ImageAdapter extends BaseAdapter {
private LayoutInflater mInflater;
public ImageAdapter() {

}
public int getCount() {
return count;
}
public Object getItem(int position) {

}
public long getItemId(int position) {

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

if (convertView == null) {

holder.imageview = (ImageView) convertView

holder.checkbox.setOnClickListener(new View.OnClickListener() {

int id = cb.getId();
if (thumbnailsselection[id]) {

} else {

}
}
});
holder.imageview.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
int id = v.getId();
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("file://" + arrPath[id]),

}
#Override
public void onBackPressed() {
// TODO Auto-generated method stub
Intent i = new Intent(UploadActivity.this, ImagesForAds.class);
UploadActivity.this.finish();
startActivity(i);
super.onBackPressed();
}
and it's worked fine, I can back data to my main activity as below :
b = getIntent().getExtras();
if (b != null) {
ImgData = b.getStringArrayList("IMAGE");
for (int i = 0; i < ImgData.size(); i++) {
map.add(ImgData.get(i).toString());
}
}
now it's ok... I need to upload those Images that I selected, here is my asyncTask:
public class ImageUploadTask extends AsyncTask<String, Void, String> {
String sResponse = null;
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
dialog = ProgressDialog.show(ImagesForAds.this, "Uploading",
"Please wait...", true);
dialog.show();
}
#Override
protected String doInBackground(String... params) {
try {
String url = "myLink";
int i = Integer.parseInt(params[0]);
Bitmap bitmap = decodeFile(map.get(i));
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(url);
entity = new MultipartEntity();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);
byte[] data = bos.toByteArray();
//entity.addPart("user_id", new StringBody("199"));
//entity.addPart("club_id", new StringBody("10"));
entity.addPart("images", new ByteArrayBody(data,
"image/jpeg", params[1]));
Log.i(TAG, "array map: " + map.get(i));
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost,
localContext);
sResponse = EntityUtils.getContentCharSet(response.getEntity());
System.out.println("sResponse : " + sResponse);
} catch (Exception e) {
if (dialog.isShowing())
dialog.dismiss();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
return sResponse;
}
#Override
protected void onPostExecute(String sResponse) {
try {
if (dialog.isShowing())
dialog.dismiss();
if (sResponse != null) {
Toast.makeText(getApplicationContext(),
sResponse + " Photo uploaded successfully",
Toast.LENGTH_SHORT).show();
count++;
if (count < map.size()) {
new ImageUploadTask().execute(count + "", "hm" + count
+ ".jpg");
}
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
}
}
and here how I invoke it :
int count = 0;
new ImageUploadTask().execute(count + "", "pk" + count + ".jpg");
The issue with AsyncTask.. it's upload only 1 image, how I can upload all images I have selected ?

This is your flaw :
if (count < map.size()) {
new ImageUploadTask().execute(count + "", "hm" + count
+ ".jpg");
}
not a good idea to create a new ImageUploadTask inside ImageUploadTask.
move your for loop inside doInBackground() and for updating user use publishProgress() and catch that event inside onProgressUpdate.

Thanks in Advance.

For sorting you need to Collection.sort method of Java and also you need to implement comparable interface for define your comparison.
CartItemoriginal implements Comparable {
public int compareTo(Object obj) { } }
Updated
public class CartItemoriginal implements Comparable<CartItemoriginal > {
private Float val;
private String id;
public CartItemoriginal (Float val, String id){
this.val = val;
this.id = id;
}
#Override
public int compareTo(ToSort f) {
if (val.floatValue() > f.val.floatValue()) {
return 1;
}
else if (val.floatValue() < f.val.floatValue()) {
return -1;
}
else {
return 0;
}
}
#Override
public String toString(){
return this.id;
}
}
and use
Collections.sort(sortList);

Get the value of clicked Item of a custom listview?

}

How can I proceed in these two scenarios?
EventParsingClass EPSP= ??? and
EPSP.getid= ??

fetch[0]="XXX"
fetch[1]="YYY"
fetch[2]="ZZZ"
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), fetch[position] + "Clicked",
Toast.LENGTH_LONG).show();
}
just declare fetch[position] to get the value of clicked item. hope this will give you some solution.

Use int position to find out values from your data list (array list or what ever you used).
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), EPSP.getid(position) + "Clicked",Toast.LENGTH_LONG).show();
}

EventItem item = (EventItem) parent.getItemAtPosition(position);
Now you have a hold of EventItem. So you can start using the get methods of your EventItem class in order to get whatever you want from it.

I got the solution:
EventParsingClass new_method(int value) {
int item_count = 0;
for (int i = 0; i < arrayOfEventDescription.size(); i++) {
ArrayList<EventParsingClass> Arraylist_for_loop = arrayOfEventDescription
.get(i);
item_count++;
for (int j = 0; j < Arraylist_for_loop.size(); j++) {
if (value == item_count) {
return Arraylist_for_loop.get(j);
}
item_count++;
}
}
return null;
}
And call it from here:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
EventParsingClass newObject = new_method(arg2);
if (newObject == null) {
} else {
Log.d("Generated Value Id : ", "" + newObject.getId());
Toast.makeText(getApplicationContext(),
"Item Clicked" + arg2 + "-----" + newObject.getTitle(),
Toast.LENGTH_LONG).show();
}
}

Custom List item change background in Android

Hi I am using custom listview and my list item contains checkbox. When updating the listview with the existing values the background is changed, so it is working fine.But when i clicks the check button, at that time the background will not changing after loading some where again then the background is changed . My question is at the time of check the item the background need to change immediately.
This is my adapter class.

I just want to change the background of the checked item immediatly without updating the list again.

I think you need to tell the BaseAdapter to refresh the data when your OnCheckedChanged Listener is called.
GuestListAdapter.this.notifyDataSetChanged()

Activity State not saved

I want to save my Activity state while I swipe between activities but I cannot. Some things are saved and the others dont. I think it has to do somehow with the gestureListener I'm impementing but I'm not sure.
When I swipe to a different activity and then back to this one - the AsyncTask is still running and the Handler is still updating the GUI, however, the views I have displaying in this activity and the buttons are all in their initial configuration.
what am I doing wrong?

You should not keep your Async task running in the background when your activity is send to the background. Your activity can be quit at any time so that you wouldn't have a reference to your activity anymore.
Regarding the preservation of state you could have a look at Activity.onRetainNonConfigurationInstance()
