Pagination doesn't work properly on list Scroll view

Following code is used for getting the new data from json on scroll of list view . But after getting the new json it does not add the new one from json instead it takes the same data that are in the first json .
Please Help me with this issue .

Crate a new class named as EndlessScrollListener
import android.widget.AbsListView;
public abstract class EndlessScrollListener implements AbsListView.OnScrollListener {
// The minimum number of items to have below your current scroll position
// before loading more.
private int visibleThreshold = 5;
// The current offset index of data you have loaded
private int currentPage = 0;
// The total number of items in the dataset after the last load
private int previousTotalItemCount = 0;
// True if we are still waiting for the last set of data to load.
private boolean loading = true;
// Sets the starting page index
private int startingPageIndex = 0;
public EndlessScrollListener() {
}
public EndlessScrollListener(int visibleThreshold) {
this.visibleThreshold = visibleThreshold;
}
public EndlessScrollListener(int visibleThreshold, int startPage) {
this.visibleThreshold = visibleThreshold;
this.startingPageIndex = startPage;
this.currentPage = startPage;
}
#Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount)
{
// If the total item count is zero and the previous isn't, assume the
// list is invalidated and should be reset back to initial state
if (totalItemCount < previousTotalItemCount) {
this.currentPage = this.startingPageIndex;
this.previousTotalItemCount = totalItemCount;
if (totalItemCount == 0) { this.loading = true; }
}
// If it's still loading, we check to see if the dataset count has
// changed, if so we conclude it has finished loading and update the current page
// number and total item count.
if (loading && (totalItemCount > previousTotalItemCount)) {
loading = false;
previousTotalItemCount = totalItemCount;
currentPage++;
}
// If it isn't currently loading, we check to see if we have breached
// the visibleThreshold and need to reload more data.
// If we do need to reload some more data, we execute onLoadMore to fetch the data.
if (!loading && (firstVisibleItem + visibleItemCount + visibleThreshold) >= totalItemCount ) {
loading = onLoadMore(currentPage + 1, totalItemCount);
}
}
// Defines the process for actually loading more data based on page
// Returns true if more data is being loaded; returns false if there is no more data to load.
public abstract boolean onLoadMore(int page, int totalItemsCount);
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
// Don't take any action on changed
}
}
Then change your code as below.
The pagecount which you are passing in you asynctask is actually the size of a list. So you can update this variable this after laoding data from the network.
public class ProductView extends AppCompatActivity {

What do you want? You want to scroll List after update List it reached at Top not at same List State? Is it Right?
Please Check this
private void scrollMyListViewToBottom() {
myListView.post(new Runnable() {
#Override
public void run() {
// Select the last row so it will scroll into view...
myListView.setSelection(myListAdapter.getCount() - 1);
}
});
}
check this Please.

Transaction ID set correctly, but displayed only a submit later

My code gives correct response and sets transaction ID correctly. But on screen, the ID is missing the first time I submit, and when I go back and submit again, then the ID on screen is the ID of the first transaction.
On the first submit, this is rendered:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID:
On the second submit, this is rendered:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID: NUFEC37WD537K5K2P9WX
I want to see the second screen the first time I submit.
Response to the first submit:
D/TID IS: ====>NUFEC37WD537K5K2P9WX D/UID IS:
====>27W3NDW71XRUR83S7RN3 D/Response-------: ------>{"tid":"NUFEC37WD537K5K2P9WX","uid":"27W3NDW71XRUR83S7RN3","status":"ok"}
Response to the second submit:
D/TID IS: ====>18R6YXM82345655ZL3E2 D/UID IS:
====>27W3NDW71XRUR83S7RN3 D/Response-------: ------>{"tid":"18R6YXM82345655ZL3E2","uid":"27W3NDW71XRUR83S7RN3","status":"ok"}

Because you have used Volley library which is already asynchronous, you don't have to use AsyncTask anymore.
Your code can be updated as the following (not inside AsyncTask, direct inside onCreate for example), pay attention to // update TextViews here...:
...
String url = "http://www.example.com/index.php";
RequestQueue requestQueue = Volley.newRequestQueue(this);
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject json_Response = new JSONObject(response);
String _TID = json_Response.getString("tid");
String _uid = json_Response.getString("uid");
String _status = json_Response.getString("status");
String tid_m =mytid.setTId_name(_TID);
Log.d("TID IS","====>"+tid_m);
Log.d("UID IS","====>"+_uid);
// update TextViews here...
txtTransId.setText(_TID);
txtStatus.setText(_status);
...
} catch (JSONException e) {
e.printStackTrace();
}
Log.d("Response-------", "------>" + response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Responce error==","===>"+error);
error.printStackTrace();
}
}
requestQueue.add(postRequest);
...
P/S: since the reponse data is a JSONObject, so I suggest you use JsonObjectRequest instead of StringRequest. You can read more at Google's documentation.
Hope it helps!

Your line of code should be executed after complete execution of network operation and control comes in onPostExecute(); of your AsyncTask.
confirm_tId.setText(_tid);

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. My code is running perfectly fine when using normal listview adapter. I an trying to use CWAC- endless adpater. I can get how to run it with my asynctask as it gives me blank screen after loding.

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);
}

autocomplete freeze when making searchs too fast

I have the next code to make search of artist and songs on the spotify servers. I have an autocomplete text but my problem is if I search for something, like "David Guetta" and I try to delete with backspace ( <-- ) everytime that I delete one character it makes a search, and if I do it so fast the app crashes (heavy usage?). I don't know really if it is for that question.
What can I do to fix this? With a wait time to search it can be fixed but I don't know how to do it.
Can you help me with this? Thank you.

If I am right, this the code that I need. The problem is how to stop it. ¬¬
//Declare the timer
Timer t = new Timer();
//Set the schedule function and rate
t.scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
//Called each time when 1000 milliseconds (1 second) (the period parameter)
}
},
//Set how long before to start calling the TimerTask (in milliseconds)
0,
//Set the amount of time between each execution (in milliseconds)
1000);

I think you are already giving a good solution.
Try wrapping the http request within a TimerTask and create a timer mechanism to cancel out the TimerTask.
Example (not tested):
public class SearchMusic extends Activity {
AutoCompleteTextView autoCompleteSongs;
String searchTerms;
String[] arrayArtist = new String[64];
String[] arrayTrack = new String[64];
ArrayAdapter<String> adapter;
List<String> songs;
List<String> lArtist;
List<String> lTrack;
//Declare and initialize the timer
Timer t = new Timer();
boolean bothsearchs = false; // Controlamos que haya busqueda por artista y
// pista si uno no existe.
int nArtist = 0; // iterator
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

The best thing you can do is using a handler, this is a simple example with a button. But the button represents the backspace on your code.
The idea is to schedule the search action within 500 miliseconds but when someone hits the search button again, we reschedule the search action until the user stops hitting the search button.
Good luck!
public class MyActivity extends Activity implements OnClickListener
{
protected static final int MSG_SEARCH = 0;
protected Button buttonSearch;
protected Handler handler = new Handler()
{
public void handleMessage(android.os.Message msg)
{
switch (msg.what)
{
case MSG_SEARCH:
MyActivity.this.search();
break;
}
}
};
#Override
public void onClick(View inView)
{
if (inView == this.buttonSearch)
{
this.handler.removeMessages(MSG_SEARCH);
final Message message = Message.obtain(this.handler, MSG_SEARCH);
this.handler.sendMessageDelayed(message, 500);
}
}
protected void search()
{
// your seach code
}
}

I had the same problem when i was using GooglePlaceApi to get list of addresses. I used synchronized in the performFiltering(), publishResults() and also the method that does the rest call. It worked for me. Maybe you can give a try.
synchronized (input)
{
// Do something inside
}
