Adapter not showing data obtained from Parse.com through AsyncTask

Adapter not showing data obtained from Parse.com through AsyncTask - android

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) {

}
catch (Exception e){
return 0;
}
}
#Override
public ParseObject getItem(int position) { return parseArray.get(position); }
#Override

return position;
}
public String getObjectId(int position){

{
Comparator<ParseObject> comparator = new Comparator<ParseObject>() {

}
};
Collections.sort(parseArray, comparator);
notifyDataSetChanged();
}

This is the method from which I am calling it..
public class WelcomeParse extends Activity {
ListView currentListView;
List<ParseObject> currentList;
ParseObjectAdapter itemAdder;
String catg;
DBShoppingHelper mydb2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
overridePendingTransition(R.anim.left_in, R.anim.right_out);
setTheme(android.R.style.Theme_Holo_Light_DarkActionBar);
setContentView(R.layout.activity_main);
itemAdder = new ParseObjectAdapter(this, getLayoutInflater());
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();
}
}

Clarification:
How do to Filter while click the Filter Button On DashBoard Fragment. Please Suggest the way. I here by attached My Filter design also.
Dashboard Fragment--> Filter Button-> Filter screen-> the Filtered results should view on DashBoard Fragment.
Once click the apply Button Based on the input from Filter screen it filters the list view the result comes from back end team. I have to display that result on Dashboard Fragment.
Kindly please clarify this Filter concept.

onbackpress listview becomes null

backaro.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {
Intent intent = new Intent(WishFamilyMember.this, WishFriendsFamily.class);

Your backaro.setOnClickListener in WishFamilyMember should looks like :
backaro.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(WishFamilyMember.this, WishFriendsFamily.class);
intent.putExtra("friendname",friendname );
intent.putExtra("friendimage",friendimage );
intent.putExtra("frienid",frienid );
intent.putExtra("userloginid",userloginid );
startActivity(intent);
}
});
or you can call onBackPressed(); rather than sending Intent like this :
backaro.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});
I hope i will work fine.

Android Listview Scroll position

I have a ListView and a list view adapter. The adapter populates the ListView from a List. The list view has a onScrollListener. The problem I have is when on scroll new data are loaded to the view but the scroll bar jumps to the top of the view.
What I want is to keep the scroll position where it was!
Any help?
Thanks

You are doing wrong in your GetItems and LoadMoreDataTask AsyncTask. you are setting new adapter each time when you scroll down so when new data are loaded to the view the scroll bar jumps to the top of the view.
You need to call
adapter = new ListViewAdapter(AppList.this, applicationList,listview);
listview.setAdapter(adapter);
only first time then you have to only call
adapter.notifyDataSetChanged()
to update your ListView no need to set adapter each time when making new request and also you have to set OnScrollListener to ListView only one time currently new OnScrollListener is set each time when making new request.

You need to setAdapter first time when adapter is null or you are fetching data first time after it just call notifyDataSetChanged()

Save state of listview before updating and then restore:
// save index and top position
int index = mListView.getFirstVisiblePosition();
View v = mListView.getChildAt(0);
int top = (v == null) ? 0 : v.getTop();
// notify dataset changed or re-assign adapter here
// restore the position of listview
mListView.setSelectionFromTop(index, top);

The most Optimal Solution will be
// 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);

Fetching education and work details from linked in

I have to fetch LinkedIn details from the loginned user . I am able to get basic basic details through the below code.
d.setVerifierListener(new OnVerifyListener() {
#Override
public void onVerify(String verifier) {
try {
Log.i("LinkedinSample", "verifier: " + verifier);
accessToken = LinkedinDialog.oAuthService
.getOAuthAccessToken(LinkedinDialog.liToken,
verifier);
LinkedinDialog.factory.createLinkedInApiClient(accessToken);
client = factory.createLinkedInApiClient(accessToken);
Person p = client.getProfileForCurrentUser();
name.setText("Welcome " + p.getFirstName() + " "
+ p.getLastName());
} catch (Exception e) {
Log.i("LinkedinSample", "error to get verifier");
e.printStackTrace();
}
}
Now I want to take education and work details.
Educations items = p.getEducations();
System.out.println("items =="+items);
I got values for p.getfirstname(),p.getlastname() but for p.getEducations() , I got null.
I didn't find any solution anywhere. Please help me
Thanks in advance.
