you have to tell your ListView that something changed in it's former List by calling notifyDataSetChanged() method of your adapter
Also you should not create a new instance of ArrayList, but only clear the old instance. Don't forget to check for null before clearing.

try calling the adapter again with a null like.
setListAdapter()

dynamic listview adding “Load more items” at the end of scroll

I have a listview fetching data from sql database by Json.
I want to turn it into dynamic listview that at the end of scroll, a "load more items" appears in the footer of the list while loading more items and adding them to the adapter (for example 10 items each time). I have problem in implementing this feature. Please help me with it.Thankx.

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.

CustomList adapter = new CustomList(Setting.this, list);
listView1.setAdapter(adapter);
Using this i am trying to print data in listview item but I am getting blank value in each item while Number Json is 49 and i am getting that 49 but getDesignation and getEmploye I am getting blank value please check and tell me where I am doing mistake I have tried much unable to get Print that value please check suggest me

Where are you inistailizind the Id,Designation and EmployeeName, it will be null itself. so doInBackground wont add any datamodel. remove the check
class GetUserdetail extends AsyncTask<Void, Void, Void> {
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
try {
String json = HttpHitter.ExecuteData(Url);
_jarray = new JSONArray(json);
System.out.println("_jarray" + _jarray);
for (int i = 0; i <= _jarray.length(); i++) {
DataModel datamodel = new DataModel();
JSONObject _obj = _jarray.getJSONObject(i);
datamodel.setId(_obj.getString("Id"));
datamodel.setDesignation(_obj.getString("Designation"));
datamodel.setEmployeeName(_obj.getString("EmployeeName"));
list.add(datamodel);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
CustomList adapter = new CustomList(Setting.this, list);
listView1.setAdapter(adapter);
}
}

Initialise the model inside the for loop and try once.

To identify changes in your list item you should call
adapter.notifyDataSetChanged();
call it before setting adapter to list view.

Listview with filter

i am trying to filter the listview using edit text at the top but it providing null pointer exception in the adapter2.filter(text) of add text changed listener . please provide me some suggestion`
Here is my edit text`
friendsList.setAdapter(new FriendListAdapter(this));
search.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
String text = search.getText().toString().toLowerCase(Locale.getDefault());
System.out.println("test=="+text);
adapter2.filter(text);
}
#Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
//adapter.getFilter().filter(arg0.toString());
}

i am passing the facebook friend list to the listview.please provide some suggestion
Thanks in advance

For filter the listview using edit text at the top .
I used this code.
Make one list called searchResults than in onTextChanged method of edittext simply do this-
String searchString = `your edittext object`.getText().toString();
int textLength = searchString.length();
searchResults.clear();
for (int i = 0; i < `your main list of items`.size(); i++) {
String name = `your main list of items`.get(i).get("`your key`").toString();
System.out.println(" name " + name);
if (textLength <= title.length()) {
// compare the String in EditText with Names in the
// ArrayList
if (searchString.equalsIgnoreCase(name.substring(0, textLength))) {
searchResults.add(`your main list of items`.get(i));
System.out.println("the array list is "+ `your main list of items`.get(i));
mAdapter = new Adapter(this, searchResults);
`your ListView object`.setAdapter(mAdapter);
}
}
}
if (searchResults.isEmpty()) {
Toast toast = Toast.makeText(getApplicationContext(),"No Items Matched",Toast.LENGTH_SHORT);
toast.show();
mAdapter = new Adapter(this, searchResults);
`your ListView object`.setAdapter(mAdapter);
}
mAdapter.notifyDataSetChanged();
and on setOnItemClickListener just check searchResults.isEmpty() if true than use your your main list of items and if false than use searchResults list.
May be it will help you.try this.

change your filter with following code:
#Override
public Filter getFilter() {
//Log.d("in filter", "yes");
return new Filter() {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
final FilterResults oReturn = new FilterResults();
and set your list in this function and after set your list :
oReturn.values = YourList;
and finall
return oReturn;
and in Your search.addTextChangedListener(new TextWatcher()) just in onTextChanged add following line:
adapter2.getFilter().filter(s.toString());

Try this,
adapter2=new FriendListAdapter(this);
friendsList.setAdapter(adapter2);
