I'm not allowed to flag at this moment, but this might be a duplicate of how can i use the number from textfield of each row in listview and make a call on this number?
Anyway, my answer given there might solve your problem:
Here is what I do:
private class MyAdapter extends BaseAdapter {
private ListView listView;
...
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
this.listView = (ListView) viewGroup;
and then in each View.OnClickListener I can get the position of the clicked item by
#Override
public void onClick(View view) {
...
MyAdapter.this.listView.getPositionForView((View) view.getParent()));

ListView not displaying data in fragment

I am using listview to populate data coming from the server. This listview will show that data in a fragmentTab. Now the data is parsing fine and logcat is also showing the data. But the data is not being populated by listview. I tried to see the error through debugging but there is no problem. Even the Holder in adapter catches the data but it's not displayed. I don't know what the problem is. I tried the following questions but didn't got the answer.

Note: I already tried declaring listview and assigning adapter in onActivityCreated() method of fragment but no effect.
Any Help will be appreciated.

Hello see the modifiy version of your adapter. Let me know if you have any problem with it.
public class HistoryAdapter extends BaseAdapter
{
private Context activity;
TextView tv_date;
TextView tv_loginTime;
TextView tv_logoutTime;
private ArrayList<Pojo> arraylist = null;
public static LayoutInflater inflater;
private Context context;
public HistoryAdapter(Context a) {
activity = a;
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.arraylist = new ArrayList<Pojo>();
}
#Override
public int getCount() {
return list.size();
}
#Override
public Object getItem(int position) {
return list.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public void addHistoryData(ArrayList<Pojo> newDataset){
if(arraylist != null){
arraylist.addAll(newDataset);
}
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder mViewHolder = null;
if(convertView == null)
{
mViewHolder = new ViewHolder();
convertView = inflater.inflate(R.layout.history_item, parent, false);
mViewHolder.tv_date = (TextView) convertView.findViewById(R.id.historyDate);
mViewHolder.tv_loginTime = (TextView)convertView.findViewById(R.id.historyLoginTime);
mViewHolder.tv_logoutTime = (TextView)convertView.findViewById(R.id.historyLogoutTime);
convertView.setTag(mViewHolder);
}else{
mViewHolder = (ViewHolder) convertView.getTag();
}
final Pojo pojo = list.get(position);
mViewHolder.tv_date.setText(pojo.getDate());
mViewHolder.tv_loginTime.setText(pojo.getLoginTime());
mViewHolder.tv_logoutTime.setText(pojo.getLogoutTime());
return v;
}
public class ViewHolder{
TextView tv_date
TextView tv_loginTime;
TextView tv_logoutTime;
}
}
In next the activity NetCheck class when web service response come change like below :
history.add(pojo);
myAdapter.addHistoryData(history);
myAdapter.notifiyDatasetChanged();

There may be problem you are getting repeated value in array, please check your array first.

Custom adapter never empty

What I want is check if adapter is empty and append data to listview if it is empty else fill the listview with data and notifyDataSetChanged. I'm implementing OnScrollListener to load more data from server. But adapter never is empty and always notifyDataSetChanged is called.
My List Activity
public class ListResultActivity extends Activity implements OnScrollListener{
private ArrayList<BusinessListData> businesses;
private ListView businessList;
private LayoutInflater layoutInflator;
private BusinessListIconTask imgFetcher;
BusinessListDataAdapter adapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.businesslist);
this.businessList = (ListView) findViewById(R.id.lvBusinesslist);
this.adapter= new BusinessListDataAdapter(this,
this.imgFetcher, this.layoutInflator, this.businesses);
getData();
businessList.setOnScrollListener(this);
}
#Override
public Object onRetainNonConfigurationInstance() {
Object[] myStuff = new Object[2];
myStuff[0] = this.businesses;
myStuff[1] = this.imgFetcher;
return myStuff;
}
/**
* Bundle to hold refs to row items views.
*
*/
public static class MyViewHolder {
public TextView businessName, businessAddress, phoneNo;
public Button btnProfile;
public ImageView icon;
public BusinessListData business;
}
public void setBusinesses(ArrayList<BusinessListData> businesses) {
this.imgFetcher = new BusinessListIconTask(this);
this.layoutInflator = LayoutInflater.from(this);
this.businesses = businesses;
if(adapter !=null){
this.adapter.notifyDataSetChanged();
}else{
this.adapter= new BusinessListDataAdapter(this,
this.imgFetcher, this.layoutInflator, this.businesses);
businessList.setAdapter(adapter);
}
}
private void getData() {
// TODO Auto-generated method stub
Intent myIntent = getIntent();
// gets the arguments from previously created intent
String metroTxt = myIntent.getStringExtra("key");
String metroLoc = myIntent.getStringExtra("loc");
String metroId = myIntent.getStringExtra("qt");
BusinessListApiTask spTask = new BusinessListApiTask(
ListResultActivity.this);
try {
spTask.execute(metroTxt, metroLoc, metroId);
} catch (Exception e) {
spTask.cancel(true);
}
}
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
// TODO Auto-generated method stub
}
#Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
// TODO Auto-generated method stub
if (businessList.getLastVisiblePosition() == totalItemCount - 1) {
getData();
adapter.notifyDataSetChanged();
Log.d("test count", "abc"+totalItemCount);
}
}
}
Class to fetch data from server and set to adapter
public class BusinessListApiTask extends AsyncTask<String, Integer, String> {
private ProgressDialog progDialog;
private Context context;
private ListResultActivity activity;
private static final String debugTag = "sodhpuch";
HashMap<String, String> queryValues;
/**
* Construct a task
*
* #param activity
*/
public BusinessListApiTask(ListResultActivity activity) {
// TODO Auto-generated constructor stub
super();
this.activity = activity;
this.context = this.activity.getApplicationContext();
}
#Override
protected void onPreExecute() {
super.onPreExecute();
progDialog = ProgressDialog.show(this.activity, "Search", this.context
.getResources().getString(R.string.looking_for_business), true,
false);
}
#Override
protected String doInBackground(String... params) {
try {
// Log.d(debugTag, "Background:" +
// Thread.currentThread().getName());
String result = BusinessListHelper.downloadFromServer(params);
// try {
//
// updateSQLite(result);
//
// } catch (Exception e) {
// return result;
// }
Log.d("result", result);
return result;
} catch (Exception e) {
return new String();
}
}
#Override
protected void onPostExecute(String result) {
ArrayList<BusinessListData> businessData = new ArrayList<BusinessListData>();
progDialog.dismiss();
try {
JSONObject respObj = new JSONObject(result);
int success = respObj.getInt("success");
Log.d("Success", "abc"+success);
if (success == 1) {
JSONArray tracks = respObj.getJSONArray("idioms");
for (int i = 0; i < tracks.length(); i++) {
JSONObject track = tracks.getJSONObject(i);
String businessName = track.getString("name");
String businessAddress = track.getString("address");
String phone = track.getString("phone");
String id = track.getString("id");
String deals_in = track.getString("deals_in");
businessData.add(new BusinessListData(businessName,
businessAddress, id, phone, deals_in));
}
} else {
Log.d("Success", "first"+success);
// Log.d(debugTag, "Background:" + result);
// DBController controller = new DBController(context);
// businessData = controller.getBusinessList();
return ;
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// }
this.activity.setBusinesses(businessData);
}
My Adapter
public class BusinessListDataAdapter extends BaseAdapter implements
OnClickListener {
private static final String debugTag = "BusinessListDataAdapter";
private ListResultActivity activity;
private BusinessListIconTask imgFetcher;
private LayoutInflater layoutInflater;
private ArrayList<BusinessListData> businesses;
BusinessListData business;
public BusinessListDataAdapter(ListResultActivity a,
BusinessListIconTask i, LayoutInflater l,
ArrayList<BusinessListData> data) {
this.activity = a;
this.imgFetcher = i;
this.layoutInflater = l;
this.businesses = data;
}
#Override
public int getCount() {
return this.businesses.size();
}
public void clear()
{
businesses.clear();
notifyDataSetChanged();
}
#Override
public boolean areAllItemsEnabled() {
return true;
}
#Override
public Object getItem(int arg0) {
return null;
}
#Override
public long getItemId(int pos) {
return pos;
}
#Override
public View getView(int pos, View convertView, ViewGroup parent) {
MyViewHolder holder;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.trackrow, parent,
false);
holder = new MyViewHolder();
holder.businessName = (TextView) convertView
.findViewById(R.id.tvBusinessName);
holder.businessAddress = (TextView) convertView
.findViewById(R.id.tvAddress);
holder.phoneNo = (TextView) convertView.findViewById(R.id.tvPhone);
holder.icon = (ImageView) convertView.findViewById(R.id.album_icon);
holder.btnProfile = (Button) convertView
.findViewById(R.id.btnProfile);
holder.btnProfile.setTag(holder);
convertView.setTag(holder);
} else {
holder = (MyViewHolder) convertView.getTag();
}
convertView.setOnClickListener(this);
business= businesses.get(pos);
holder.business = business;
holder.businessName.setText(business.getName());
holder.businessAddress.setText(business.getAddress());
holder.phoneNo.setText(business.getPhone());
holder.btnProfile.setOnClickListener(this);
// if(track.getImageUrl() != null) {
// holder.icon.setTag(track.getImageUrl());
// Drawable dr = imgFetcher.loadImage(this, holder.icon);
// if(dr != null) {
// holder.icon.setImageDrawable(dr);
// }
// } else {
holder.icon.setImageResource(R.drawable.filler_icon);
// }
return convertView;
}
#Override
public void onClick(View v) {
String deals_in = business.getDeals().toString();
Log.d("name", deals_in);
MyViewHolder holder = (MyViewHolder) v.getTag();
if (v instanceof Button) {
Intent profile = new Intent(activity,
ProfileActivity.class);
profile.putExtra("deals_in", deals_in);
profile.putExtra("phone", holder.business.getPhone());
profile.putExtra("address", holder.business.getAddress());
profile.putExtra("name", holder.business.getName());
this.activity.startActivity(profile);
} else if (v instanceof View) {
Log.d("test","call testing");
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" +holder.business.getPhone()));
this.activity.startActivity(intent);
}
Log.d(debugTag, "OnClick pressed.");
}
}

Try this way,hope this will help you to solve your problem.
public void setBusinesses(ArrayList<BusinessListData> businesses) {
imgFetcher = new BusinessListIconTask(this);
layoutInflator = LayoutInflater.from(this);
if(this.businesses == null || adapter==null){
this.businesses = new ArrayList<BusinessListData>();
adapter= new BusinessListDataAdapter(this,imgFetcher,layoutInflator,this.businesses);
businessList.setAdapter(adapter);
}
this.businesses.addAll(businesses);
adapter.notifyDataSetChanged();
}

You have the adapter object in your setBusinesses Method. You just need to check the size of the adapter too as follows which is solve your problem.
if(adapter !=null && adapter.getCount()>0)
{
this.adapter.notifyDataSetChanged();
}
else
{
this.adapter= new BusinessListDataAdapter(this,
this.imgFetcher, this.layoutInflator, this.businesses);
businessList.setAdapter(adapter);
}
this will check the size of your BusinessListData object in the adapter and this will not initialize the adapter again and again.
Hope this Solves your problem.
Thank You!

Change use of OnScrollListener. Use Asynctask class and onPreExecute() set adapter as null. Load data in doInBackground() method and call custom adapter in onPostExecute(). I hope it 'll work fine.
