Cant access viewHolder in a customArrayadapter in another function?

I am creating an application with a list that list cards based on the value from the server.
I created a StudentCardArrayAdapter to achieve this and everything works fine. All the data has been populated in card list. also I able to get the values on button click in each card separately.
What I need is on clicking the button it will call a method requestion server for data asynchronously and get a value from the server and according to that value, i need to change the button text in that particular card.
My StudentCardArrayAdapter code:
public class StudentCardArrayAdapter extends ArrayAdapter<StudentCard> {
private static final String TAG = "CardArrayAdapter";
private List<StudentCard> cardList = new ArrayList<StudentCard>();
private Context mContext;
String selected = "0";
PreferenceHelper prefs;
CardViewHolder viewHolder;
View row;
ProgressDialog pd;
static class CardViewHolder {
TextView studentname;
TextView stop;
Button selectbutton;
CircleImageView imageId;
}
public StudentCardArrayAdapter(Context context, int textViewResourceId) {
super(context, textViewResourceId);
this.mContext = context;
prefs = new PreferenceHelper(this.mContext);
pd = new ProgressDialog(this.mContext);
}
#Override
public void add(StudentCard object) {
cardList.add(object);
super.add(object);
}
#Override
public int getCount() {
return this.cardList.size();
}
#Override
public StudentCard getItem(int index) {
return this.cardList.get(index);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
row = convertView;
if (row == null) {
LayoutInflater inflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.student_card, parent, false);
viewHolder = new CardViewHolder();
viewHolder.studentname = (TextView) row.findViewById(R.id.studentname);
viewHolder.stop = (TextView) row.findViewById(R.id.stop);
viewHolder.selectbutton = (Button) row.findViewById(R.id.selectbutton);
viewHolder.imageId = (CircleImageView) row.findViewById(R.id.imageId);
row.setTag(viewHolder);
} else {
viewHolder = (CardViewHolder)row.getTag();
}
StudentCard card = getItem(position);
viewHolder.studentname.setText(card.getStudName());
viewHolder.studentname.setTextColor(Color.parseColor("#000000"));
viewHolder.stop.setText(card.getStudStop());
viewHolder.stop.setTextColor(Color.parseColor("#000000"));
if(card.getSelected().equals("1")){
viewHolder.selectbutton.setText(mContext.getResources().getString(R.string.selected));
viewHolder.selectbutton.setEnabled(false);
}
else{
viewHolder.selectbutton.setText(mContext.getResources().getString(R.string.select));
viewHolder.selectbutton.setEnabled(true);
}
final String studid = card.getStudId();
final String busname = prefs.getString("busname", "0");
final String schoolid = prefs.getString("schoolid", "");
viewHolder.selectbutton.setOnClickListener(new View.OnClickListener()
{
String updatedvalue = "0";
#Override
public void onClick(View v)
{
Log.e("studid",studid);
Log.e("busname",busname);
Log.e("schoolid",schoolid);
selectstudent(v, studid, busname, schoolid,mContext);
//Toast.makeText(v.getContext(), amountinfo, Toast.LENGTH_SHORT).show();
/*SnackbarManager.show(Snackbar.with(this) // context
.text(amountinfo));*/
}
});
Picasso.with(mContext).load(card.getImageUrl()).fit().error(R.mipmap.ic_launcher).into(viewHolder.imageId);
return row;
}
public void selectstudent(final View v, String studid, String busname, String schoolid, final Context mContext) {
String returnedselected = "0";
Log.e("BASE_URL_STUDENT_UPDATE", Constants.BASE_URL_STUDENT_UPDATE + "?studid=" + studid+"&busname="+busname+"&schoolid="+schoolid);
RestClientHelper.getInstance().get(Constants.BASE_URL_STUDENT_UPDATE + "?studid=" + studid+"&busname="+busname+"&schoolid="+schoolid, new RestClientHelper.RestClientListener() {
#Override
public void onSuccess(String response) {
Log.e("RESULT", response);
try {
JSONObject result = new JSONObject(response);
JSONArray posts = result.optJSONArray("status");
for (int i = 0; i < posts.length(); i++) {
JSONObject post = posts.optJSONObject(i);
String status = post.optString("status");
if (status.equals("true")) {
selected = post.optString("selected");
} else {
selected = post.optString("selected");
String error = post.optString("error");
SnackbarManager.show(Snackbar.with(getContext()) // context
.text(error));
}
}
} catch (JSONException e) {
e.printStackTrace();
} catch (Exception e) {
} finally {
if(selected.equals("1")){
viewHolder.selectbutton.setText(mContext.getResources().getString(R.string.selected));
viewHolder.selectbutton.setEnabled(false);
}
}
}
#Override
public void onError(String error) {
Log.e("error", error);
selected = "0";
}
});
}
}
I used the below code but nothing works.. No error also.. and not change in button text.I get value of selected as 1 from server.
if(selected.equals("1")){
viewHolder.selectbutton.setText(mContext.getResources().getString(R.string.selected));
viewHolder.selectbutton.setEnabled(false);
}
I am new to android.. and is stuck here. Please help me out.
FINALLY IT WORKED
As changes mention by Krish, I updated the code suggested by him.
And added this changes in onClick it worked
if(card.getSelected().equals("1")){
viewHolder.selectbutton.setText(mContext.getResources().getString(R.string.selected));
viewHolder.selectbutton.setEnabled(false);
}

Change the code like this,
public void selectstudent(StudentCard card, String studid, String busname, String schoolid, final Context mContext) {
String returnedselected = "0";
Log.e("BASE_URL_STUDENT_UPDATE", Constants.BASE_URL_STUDENT_UPDATE + "?studid=" + studid+"&busname="+busname+"&schoolid="+schoolid);
RestClientHelper.getInstance().get(Constants.BASE_URL_STUDENT_UPDATE + "?studid=" + studid+"&busname="+busname+"&schoolid="+schoolid, new RestClientHelper.RestClientListener() {
#Override
public void onSuccess(String response) {
Log.e("RESULT", response);
try {
JSONObject result = new JSONObject(response);
JSONArray posts = result.optJSONArray("status");
for (int i = 0; i < posts.length(); i++) {
JSONObject post = posts.optJSONObject(i);
String status = post.optString("status");
if (status.equals("true")) {
selected = post.optString("selected");
} else {
selected = post.optString("selected");
String error = post.optString("error");
SnackbarManager.show(Snackbar.with(getContext()) // context
.text(error));
}
}
} catch (JSONException e) {
e.printStackTrace();
} catch (Exception e) {
} finally {
if(selected.equals("1")){
card.setSelected("1");
notifyDataSetChanged();
}
}
}
#Override
public void onError(String error) {
Log.e("error", error);
selected = "0";
}
});
}
and change this line like this ,
final StudentCard card = getItem(position);
and call method inside onclick.
selectstudent(card, studid, busname, schoolid,mContext);

Remove an item from view inside an adapter

I am trying to remove an item from view when its flag become 4. I tried mObjects.remove(position) and then notifyDataSetChanged(). but it didn't worked.we tried all the following
if (getItem(position).getFlag().trim().equalsIgnoreCase("4")) {
remove(position);
adapter.notifyDataSetChanged();
matcheslistview.setAdapter(adapter);
also this one
// mObjects.remove(position)
// notifyDataSetChanged();
and this one
// mObjects.remove(position);
//remove(position);
//mainObjects.remove(position);
//notifyDataSetChanged();
and this one
// Object toRemove = adapter.getItem(position);
// mObjects.remove(toRemove);
// mObjects.clear();

Don't remove the object in getview, if you have to filter it, filter it before sending out to adapter. May be possible that while creating the child view the 1st cell has tag "4" now the view didn't create(since return was not called) but you are trying to remove its position, so it will definitely give you IndexOutOfBoundsException.
My best solution would be, set the adapter with
new ArrayList<LikeMatcheddataForListview>()
whenever you start the screen. Once your AsyncTask completes filter out the child with tags "4"(better filter it out in the asynctask only, less task in ui thread) then refresh the adapter, like
public void refresh(ArrayList<LikeMatcheddataForListview>() arrObjects){
objects = arrObjects;
notifyDataSetChanged();
}
Check it out, it should do the trick

Please try following
Your code
if (getItem(position).getFlag().trim().equalsIgnoreCase("4")) {
mObjects.remove(position);
adapter.notifyDataSetChanged();
matcheslistview.setAdapter(adapter);
}
TO
do not set adapter again to list view
if (getItem(position).getFlag().trim().equalsIgnoreCase("4")) {
mObjects.remove(position);
notifyDataSetChanged();
}

This may not be correct approach to remove the item form listview.
Whenever your adapter data is getting changed then just check if that flag matches your string i.e. "4" in each item and remove the respective item from the list and just call notifyItemRemoved with position insted of notifyDataSetChanged

android custom List Adapter repeat old item

this is my custom adapter i use it for first time its work without repeat
public class MessageAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<MessageList> MessageList;
private final Context context;
public MessageAdapter(Activity activity, List<MessageList> MessageList, Context c) {
this.activity = activity;
this.MessageList = MessageList;
this.context = c;
}
#Override
public int getCount() {
return MessageList.size();
}
#Override
public Object getItem(int location) {
return MessageList.get(location);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder mHolder;
final MessageList m = MessageList.get(position);
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
if (m.getDir().equals("left")) {
convertView = inflater.inflate(R.layout.left_message, null);
} else if (m.getDir().equals("right")) {
convertView = inflater.inflate(R.layout.right_message, null);
}
mHolder = new ViewHolder();
mHolder.message = (LinearLayout) convertView.findViewById(R.id.messages);
convertView.setTag(mHolder);
for(String message : m.getMessageList()){
TextView text = new MyTextView(activity);
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
p.setMargins(0, 0, 0, 2);
text.setLayoutParams(p);
text.setText(message);
text.setPadding(8,8,8,8);
text.setTextSize(14f);
}
}
else {
mHolder = (ViewHolder) convertView.getTag();
}
Log.d("ffffffffffffffffff",""+m.getMessageList().size());
return convertView;
}
private class ViewHolder {
private LinearLayout message;
}
}
this is the result
but when i receive new data and i want to add it after do
adapter.notifyDataSetChanged();
its repeat the first data and add it to listView see result
we can see its repeat the data it must add new data i add it to arrayList not repeat old item on it i am sure about my ArrayList its right
at the end just lets see ho9w i add new data
first when its work without problem
private List<MessageList> Message_List = new ArrayList<MessageList>();
adapter = new MessageAdapter(this, Message_List, getApplicationContext());
message_list.setAdapter(adapter);
now i will add data for the first time
try {
JSONArray jsonarray = new JSONArray(data);
for (int i = 0; i < jsonarray.length(); i++) {
try {
JSONObject jsonobject = jsonarray.getJSONObject(i);
MessageList messageList = new MessageList();
String fname = jsonobject.getString("Fname");
int user_id = jsonobject.getInt("user_id");
String message = jsonobject.getString("message");
String date = jsonobject.getString("date");
String direction = jsonobject.getString("direction");
JSONArray MessageArry = jsonobject.getJSONArray("message");
ArrayList<String> ListMessage = new ArrayList<String>();
for (int j = 0; j < MessageArry.length(); j++) {
ListMessage.add((String) MessageArry.get(j));
}
messageList.setUser_id(user_id);
messageList.setMessage(message);
messageList.setDate(date);
messageList.setFname(fname);
messageList.setDir(direction);
messageList.setMessageList(ListMessage);
Message_List.add(messageList);
} catch (JSONException e) {
// JSON error
e.printStackTrace();
Toast.makeText(getApplicationContext(), "Json error: " + e.getMessage(), Toast.LENGTH_LONG).show();
}
}
adapter.notifyDataSetChanged();
} catch (JSONException e) {
// JSON error
e.printStackTrace();
Toast.makeText(getApplicationContext(), "Json error: " + e.getMessage(), Toast.LENGTH_LONG).show();
}
data used its
String data = "[ { \"direction\": \"left\",\"user_id\": \"50\",\"Fname\": \"Mohamed Mohamed\", \"status\": \"online\" , \"m_status\": \"sent\", \"date\": \"9:20\", \"message\": [\"hello\",\"hahhahah ok ok say hello\",\"-_-\",\"where are \",\"u ?\"] }, { \"direction\": \"right\",\"user_id\": \"50\",\"Fname\": \"Mustafa Naser\", \"status\": \"online\" , \"m_status\": \"sent\", \"date\": \"10:20\", \"message\": [\"hello\",\"what u want :/\",\"xD\"] }]";
when i get new data and i want to append it i add data like this
try {
JSONObject jsonobject1 = new JSONObject(json);
MessageList messageList = new MessageList();
String fname = jsonobject1.getString("name");
int user_id = jsonobject1.getInt("id");
String message = jsonobject1.getString("message");
String date = jsonobject1.getString("date");
String direction = jsonobject1.getString("direction");
ArrayList<String> ListMessage = new ArrayList<String>();
for (int j = 0; j < 1; j++) {
ListMessage.add(message);
}
messageList.setUser_id(user_id);
messageList.setMessage(message);
messageList.setDate(date);
messageList.setFname(fname);
messageList.setDir(direction);
messageList.setMessageList(ListMessage);
Message_List.add(messageList);
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(), "Json error: " + e.getMessage(), Toast.LENGTH_LONG).show();
}
adapter.notifyDataSetChanged();
data used its
{"message":"qqqqqqqq","id":50,"date":"2016-06-24 04:44:06","name":"medo medo","direction":"left","mode":0}

Each time you create a view, you put all messages inside, regardless of whether you have already shown them.
The problem is with the following loop:
for(String message : m.getMessageList()) {
// add a text view for each message
}
You need to find a way to check if the message has already been shown and add it to the layout only if it's not there.

I suggest you to do as follow:
In your adapterclass add this method:
public void updateList(List<MessageList> ){
this.MessageList = l;
notifyDataSetChanged();
}
And, after you fetch the new List, call the adapter.updateList(newList) method! It will update itself with the notifyDataSetChanged(); inside of the method.

in your getView() method
if(stats[position].Equals("open"))
{
immm.setImageResource(R.drawable.open);
}
else if(stats[position].Equals("wip"))
{
immm.setImageResource(R.drawable.wip);
}
else
{
immm.setImageResource(R.drawable.closed);
}
