Android update adapter doesn't work correctly

Android update adapter doesn't work correctly - android

In this code I have a custom adapter, and after I add new data into ArrayList my adapter.notifyDataSetChanged(); doesn't work.
public class ReceiveListFragment extends ListFragment implements AbsListView.OnScrollListener {
public ArrayList<ReceivedItemStructure> items;
private int prevVisibleItem;

.getString(getActivity(),
Configuration.SharedPrefsTypes.USERNAME);
config_password = Configuration.getInstance()
.getString(getActivity(),
Configuration.SharedPrefsTypes.PASSWORD);
items = new ArrayList<ReceivedItemStructure>();
getRequestFromServer(0, 10);
adapter = new ReceivedAdapter(G.context, items);
setListAdapter(adapter);
Timer smsThread = new Timer();
GetSMSThread getSMSThread = new GetSMSThread();
smsThread.scheduleAtFixedRate(getSMSThread, 1, 10000); //(timertask,delay,period)
return super.onCreateView(inflater, container, savedInstanceState);
}
private String getRequestFromServer(long lastID, int count) {
String received = "";
try {
received = new JsonService(config_username, config_password, lastID, count, G.F_RECEIVE_SMS).request();
JSONArray data_array = new JSONArray(received);
String mUserID = config_username;
for (int i = 0; i < data_array.length(); i++) {
JSONObject json_obj = data_array.getJSONObject(i);
String mLastID = json_obj.getString("id_recived_sms");
String mSmsBody = json_obj.getString("sms_body");
String mSmsNumber = json_obj.getString("sms_number");

ReceivedItemStructure item = new ReceivedItemStructure(
mLastID,

mSmsBody,
mSmsNumber,
mSenderName,
mContactName,
mDate
);
items.add(item);
//Log.e(" ", "" + mLastID);
}
/** Creating array adapter to set data in listview */
} catch (Exception e) {
e.printStackTrace();
}
return received;
}
public long getLastID() {
return Long.parseLong(items.get(items.size() - 1).getmLastID());
}
private void addDataToList(String LastID, String SmsBody, String SmsNumber, String SenderName, String ContactName, String Date) {
String mLastID = LastID;

items.add(item);
adapter.update(items);
adapter.notifyDataSetChanged();
}
public class GetSMSThread extends TimerTask {
private Long lastID;
private SQLiteDatabase dbHelper;
private List<ReceiveListFragment> rows;
#Override
public void run() {
lastID = getLastID();
if (Configuration.getInstance().checkInternetConnection(G.context)) {
try {
Thread threadTask = new Thread() {

} catch (Exception e) {
e.printStackTrace();
} // END TRY
}

}
}
My custom Adapter code is this:
public class ReceivedAdapter extends ArrayAdapter<ReceivedItemStructure> {
private ArrayList<ReceivedItemStructure> list;
public ReceivedAdapter(Context c, ArrayList<ReceivedItemStructure> items) {
super(c,0,items);
list = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ReceiveItemView itemView = (ReceiveItemView)convertView;
if (null == itemView)
itemView = ReceiveItemView.inflate(parent);
itemView.setItem(getItem(position));
return itemView;
}
public void update(ArrayList<ReceivedItemStructure> items) {
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
addAll(items);
} else {
for (ReceivedItemStructure item : items) {
add(item);
}
}
}
}
setListAdapter(adapter); works correctly and I don't have any problem, but after I add new data into items notifyDataSetChanged it doesn't work.
My manifest content:
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="21"/>

it is the super class that is handling the dataset, since you are not overriding getCount and getItem,
public void update(ArrayList<ReceivedItemStructure> items) {
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
addAll(items);
} else {
for (ReceivedItemStructure item : items) {
add(item)
}
}
}
addAll was introduced with Honeycomb, so you probably want to check the current supported sdk where you are app is running

You are modifying your original items collection. But you should to modify adapter's data. Use ArrayAdapter.add method to add new items.

search in listview only refreshes the whole list and does not get the result into list

I am getting the data from server using JSON and when i try to search in the listview it just refreshes the whole list and does not narrate it, but when i debug i can see the result on getfilter is right right and it drugsFiltered = (ArrayList<drugs_json_data>) results.values; does have the filtered data inside it. just the listview.setadaptor is being done inside onPostExecute of the asynctask.
here is my adapter code:
public class drugs_adaptor_listView extends ArrayAdapter<drugs_json_data> implements Filterable {

How to access the ArrayList present in Adapter in Activity

I have a listview in which in each row I have a checkbox along with details o persons. Now on clicking checkboxes, I want to store the id of those persons in arrayList which I am able to store but the arrayList id in adapter. I want to access the arrayList in activity because I want to take a button in activity on clicking which I want to send ids of all the selected persons to another activity. How do I do that.

Create one method in adapter like
public class SendWorkAdapter extends BaseAdapter {
public List<SendWorkRow> getAllWorkRows() {
return send_work_array_list;
}
}
and access this method using adapter instance in activity.
Another way is you can write a method in Adapter where you will find all selected ids in a List and return. So whenever you will require list of selected ids, call this method from Activity and do your task. like
public class SendWorkAdapter extends BaseAdapter {
public List<SendWorkRow> getAllSelectedWorkRows() {
// write your logic to find selected rows
return result;
}
}

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);
