Adapter not showing data obtained from Parse.com through AsyncTask

I am trying to obtain some data from Parse.com through an AsyncTaskRunner. ANd then I intend to show them in a ListView. My custom adapter code is attached below :
public class ParseObjectAdapter extends BaseAdapter {
Context mContext;
LayoutInflater mInflater;
List<ParseObject> parseArray;
DBShoppingHelper mydb2;
public ParseObjectAdapter(Context context, LayoutInflater inflater) {

parseArray = new ArrayList<>();
}
#Override

try {

}
catch (Exception e){
return 0;
}
}
#Override
public ParseObject getItem(int position) { return parseArray.get(position); }
#Override
public long getItemId(int position) {
return position;
}
public String getObjectId(int position){
return getItem(position).getObjectId();
}
public void sortByExpiry()
{
Comparator<ParseObject> comparator = new Comparator<ParseObject>() {
#Override
public int compare(ParseObject lhs, ParseObject rhs) {
return ((Integer) lhs.getInt("expiresIn")).compareTo(rhs.getInt("expiresIn"));
}
};
Collections.sort(parseArray, comparator);
notifyDataSetChanged();
}
#Override

This is the method from which I am calling it..
public class WelcomeParse extends Activity {

mydb2 = new DBShoppingHelper(this);
AsyncTaskAllItems runner = new AsyncTaskAllItems();
runner.execute();
// itemAdder.notifyDataSetChanged();
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}
public class AsyncTaskAllItems extends AsyncTask<String, String, String> {
private String resp;
private Integer numItems = 0;
#Override
protected String doInBackground(String... params) {
try {
ParseQuery itemsAll = new ParseQuery("Items");
itemsAll.whereEqualTo("owner", ParseUser.getCurrentUser().getUsername());
// itemsByCategory.whereEqualTo("category", catg);
itemsAll.findInBackground(new FindCallback<ParseObject>() {
#Override
public void done(List<ParseObject> Items, ParseException e) {
if (e == null) {
Log.d("score", "Retrieved " + Items.size() + " scores");
Log.d("owner", ParseUser.getCurrentUser().getUsername());
// HERE SIZE is 0 then 'No Data Found!'
numItems = Items.size();
if (numItems > 0) {
currentList = Items;
}
} else {
Log.d("score", "Error: " + e.getMessage());
}
}
});
resp = "Done";
}
// catch (InterruptedException e) {
// e.printStackTrace();
// resp = e.getMessage();
// }
catch (Exception e) {
e.printStackTrace();
resp = e.getMessage();
}
return resp;
}
#Override
protected void onPostExecute(String result) {
currentListView = (ListView) findViewById(R.id.all_list);
itemAdder.updateData(currentList);
if (numItems > 0) {
itemAdder.sortByExpiry();
}
currentListView.setAdapter(itemAdder);
// onWindowFocusChanged(true);
}
#Override
protected void onPreExecute() {
}
#Override
protected void onProgressUpdate(String... text) {
}
}
}
I do not get any error and the log correctly shows the number of items that should be retrieved. But the view does not get updated with the relevant data.
COuld anyone please show me where I am wrong? Anything else you need, just let me know. Much appreciated.

Try after replacing
#Override
protected void onPostExecute(String result) {
currentListView = (ListView) findViewById(R.id.all_list);
itemAdder.updateData(currentList);
if (numItems > 0) {
itemAdder.sortByExpiry();
}
currentListView.setAdapter(itemAdder);
// onWindowFocusChanged(true);
}
With
#Override
protected void onPostExecute(String result) {
currentListView = (ListView) findViewById(R.id.all_list);
currentListView.setAdapter(itemAdder);
itemAdder.updateData(currentList);
if (numItems > 0) {
itemAdder.sortByExpiry();
}
}

how to select multiple items in a listview populated from ArrayList in Android

I am trying to write a program to select multiple items in the listview i populate. but I am having difficulty of selecting multiple items. Please let me know how to do it. Bellow is how i have populate the Arraylist and i have a custom row with checkbox. i need to get the selected items (name, number) on the button click event. Thank you in advance. I have tried to understand the other posts, but since i was unable to relate them to my code, i am not sure of how to do.
public class Contactselect extends Activity {

Try this way,hope this will help you to solve your problem.

Endless Adapter does not show any values in the listview

I am trying to use Endless listview adapter in application code but some how i am just not able to see any values in the listview.

I have updated my code. I guess my problem now is with the custom adapter as it gives me multiple values after it reaches the end of the listview. Initially i do get 10 values but after the update it gets same 10 values again but the count reaches to 121.

Replace your init() as below,
private void init() {
new FetchEventValues().execute();
}
and replace onPostExecute() with below,
#Override
protected void onPostExecute(ArrayList<EventsBean> result) {
super.onPostExecute(result);
if (this.progressdialog.isShowing()) {
this.progressdialog.dismiss();
}
// adapter = new SAmpleAdapter(EndlessAdapterExample.this,0,
// arrayEventsBeans);
// listview.setAdapter(adapter);
LIST_SIZE = arrayEventsBeans.size();
for (int i = 0; i <= BATCH_SIZE; i++) {
countriesSub.add(arrayEventsBeans.get(i));
}
setLastOffset(BATCH_SIZE);
displayList(countriesSub);
}

listview does not updates

I am expirience wierd situation because my list view updates only once.
The idia is following, i want to download posts from web, which are located on page 3 and page 5 and show both of them on listview. However, List view shows posts only from page 3. MEanwhile, log shows that all poast are downloded and stored in addList.
So the problem - objects from second itteration are not shown in listview. Help me please to fix this issue.

I think the problem is you aren't calling the super class of notifyDataSetChanged(), maybe try

rows.add(new MyAddActivateRow((LayoutInflater) activity

super.notifyDataSetChanged();

My question is : when I input words in the EditText, nothing happened. But when I press backspace did the AutoCompleteTextView show the suggestion list ... the problem is in the editAuto.setAdapter(adapter);
What is wrong?

make the following changes in your code
1) Instead of
private AutoCompleteTextView editAuto = null; JUST WRITE private AutoCompleteTextView editAuto;
2) Add this line to onCrate()
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, <your array name here>);
and remove this line from onTextChangedTask()
ArrayList<String> userNameArrayList = new ArrayList<String>();
3) Add this line to onCrate()
editAuto.setAdapter(adapter);

I know this is way late but for those who face similar problems here is the solution to show the autoCompleteTextView's drop down whenever you want i.e on button click or onTextChanged. After you set the ArrayAdapter for the autoCompleteTextView just put the following line.
autoCompleteTextView.showDropDown();
