ListView shows repeated data everytime the fragment is created

ListView shows repeated data everytime the fragment is created - android

Here is the code of my fragment where i am accesing a web service in asynctask to fetch data and display in list also i am lazy loading the images..When the fragment is created for the first time the output is correct it displays 7 items in the list which it should , the problem is when the fragment is recreated after being destroyed the data is repeated i.e if it started for the second time the list shows 14 items (7 from earlier and 7 are again fetched) and this happens everytime it recreates , the no. of items in list is 7 more than the previous.. Although in On destroy i cleared the data of the adapter and the adapter.getCount() shows 0 but still this problem exists.

You need to clear ArrayList Data just before your next call of Async Method.
In your case it would be carDetailLis.clear() new DownloadCarDetail().execute(url); or just check the flow and clear it.

I suggest to you to modify
ServiceCarListFragment.this.carDetailList.addAll(carDetailList);
in
ServiceCarListFragment.this.carDetailList = new ArrayList...
carDetailList.addAll
And you should verify if the length of carDetailList is the same after several calls to the server.

please give me some idea what to do and how to do

i guess, you should replace
msgList = MsgJSONParser.parseData(response);
MsgAdapter adapter = new MsgAdapter(ListMessage.this, msgList);
with
msgList = MsgJSONParser.parseData(response);
ArrayList<Msg_data> userList=new ArrayList();
for (int i=0;i<msgList.size();i++){
if (!userList.contains(msgList.get(i)))
userList.add(msgList.get(i));
else {
int index=userList.indexOf(msgList.get(i));
if (userList.get(index).compareTo(msgList.get(i))>0)
userList.add(msgList.get(i));
}
}
MsgAdapter adapter = new MsgAdapter(ListMessage.this, userList);`
and implement Comparable and override equals method in your Msg_data class
public class Msg_data implements Comparable {
public int id;
public String user_id;
public String user_name;
public String message;
public String is_read;
public String image_link;
public String created_at;
public String from;
public String to;
public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
public String getTo() {
return to;
}
public void setTo(String to) {
this.to = to;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUser_id() {
return user_id;
}
public void setUser_id(String user_id) {
this.user_id = user_id;
}
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getIs_read() {
return is_read;
}
public void setIs_read(String is_read) {
this.is_read = is_read;
}
public String getImage_link() {
return image_link;
}
public void setImage_link(String image_link) {
this.image_link = image_link;
}
public String getCreated_at() {
return created_at;
}
public void setCreated_at(String created_at) {
this.created_at = created_at;
}
public Msg_data() {
}
public Msg_data(int id) {
this.id = id;
}
#Override
public boolean equals(Object obj) {
try
{
return (this.getUser_id().equals(( (Msg_data)obj).getUser_id()));
}
catch(NullPointerException e){
return false;
}
}
#Override
public int compareTo(#NonNull Object o) {
SimpleDateFormat simpleDateFormat=new SimpleDateFormat("your pattern here");
try {
Date date=simpleDateFormat.parse(created_at);
Date dateOtherObject=simpleDateFormat.parse(((Msg_data)o).getCreated_at());
return date.compareTo(dateOtherObject);
}
catch (ParseException e){
return -1;
}
}
something like this:) Dont forget replace simple date format in compare method

Don't know where I did Mistake,Please Help me to findout that,Thanks in Advance.

You class members should never be declared static as you have done here -
public class OrderApprovalDetails
{
public static String date,orderid,shopname,ownername,mobile,location,itemscount,amount;
change this to
public class OrderApprovalDetails
{
public String date,orderid,shopname,ownername,mobile,location,itemscount,amount;

mTracks size is 0 I Do not know why retrieve returns null

1- MainActivity:
public class MainActivity extends AppCompatActivity {
private List<String> mListItems = Arrays.asList("Hamaki","Amr Diab");
private ArtistsAdapter mAdapter;

You should sort the list before call adapter to list the data.
Collections.sort(bdata, new Comparator<BusData>() {
public int compare(BusData o1, BusData o2) {
return o2.getFare().compareTo(o1.getFare());
}
});
for(BusData busData:bdata)
{
Log.e("Fare : ",busData.getFare());
}
After sorting completed call Adapter to list the data:
adapter = new BusDataAdapter(this, bdata);
fromto.setAdapter(adapter);
adapter.setJourneyBus(date_bus);
filter_list.addAll(bdata);
adapter = new BusDataAdapter(this, filter_list);
fromto.setAdapter(adapter);

You can use Collections.sort method for this..
Do like this...
Collections.sort(filterlist, new Comparator<bData>() {
#Override
public int compare(bData lhs, bData rhs) {
return (lhs.getFair() > rhs.getFair()) ? -1 : (lhs.getFair() > rhs.getFair()) ? 1 : 0;
}
});

You need to use comparator api in android.
Comparator<BusData> comparator=new Comparator<BusData>() {
#Override
public int compare(final BusData lhs, final BusData rhs) {
return lhs.getFare().equals(rhs.getFare());
}
};
Collections.sort(busDataList,comparator);
then your list will be sorted.

You need to give already sorted collection of buses to your adapter. Adapter shouldn't be responsible for sorting and ListView as well.
Try this:
Collections.sort(bdata, new Comparator<BusData>() {
#Override
public int compare(BusData lhs, BusData rhs) {
return lhs.getFare() > rhs.getFare();
}
});

You can use the Comparator and sort the list
class FareComparator implements Comparator{
public int Compare(Object o1,Object o2){
BusData s1=(BusData)o1;
BusData s2=(BusData)o2;
if(s1.fare==s2.fare)
return 0;
else if(s1.fare>s2.fare)
return -1;
else
return 1;
}
}
and use
Collections.sort(bdata,new FareComparator());
before the
adapter = new BusDataAdapter(this, bdata);

Update ListView Record Duplicated Android

I put a limit of 15 records to be displayed in my listview. The 15 records successfully displayed but when i clicked on load more button, it add the previous 15 records and the new records too. Here is my async task where more records is being added. I use articlesAdapter.notifyDataSetChanged(); set too but the issue remains. i believe it has something to do with articlesFiltered.size()/15)+1.

UPDATE
and the HttpFunction getMoreArticles()
public static ArrayList<Article> getMoreArticles(int page){
String url=LAST_ARTICLE_URL;
if(url.endsWith(".php"))
url+="?page="+page;
else
url+="&page="+page;
String response=getResponse(url);
if(!ERROR.equals(response)){
return JsonParsingFunctions.parseArticles(response);
}
return null;
}

What is happening is concatenation in the method call. articlesFiltered.size()/15 is giving 1, then the +1 is not ADDING 1, it is concatenating 1, i.e 1+1 = 11 NOT 2. You could create a method
public int addOne(int i){
return i+1;
}
and use
ArrayList<Article>moreArticles=HTTPFunctions.getMoreArticles(addOne((articlesFiltered.size()/15)));
That should work providing the rest of the code is good

what variable is your adapter?
you notify your adapter but i don't see that you add datas to your articlesAdapter

Develop Reference

The Android operating system is a mobile operating system that was developed by Google (GOOGL?) to be primarily used for touchscreen devices, cell phones, and tablets.

ListView shows repeated data everytime the fragment is created - android

You need to clear ArrayList Data just before your next call of Async Method. In your case it would be carDetailLis.clear() new DownloadCarDetail().execute(url); or just check the flow and clear it.

I suggest to you to modify ServiceCarListFragment.this.carDetailList.addAll(carDetailList); in ServiceCarListFragment.this.carDetailList = new ArrayList... carDetailList.addAll And you should verify if the length of carDetailList is the same after several calls to the server.
