You can't remove anything from an array - they're always fixed length. Once you've created an array of length 3, that array will always have length 3. And if you want to delete from the listview the array which you are used should be dynamic(Adding & Deleting). So make the pIdz; pNamz;pPrizs;userData into some Modal Object, and prepare the list of Modal Objects and pass it to adapter and make the life easier
You'd be better off with a List, e.g. an ArrayList:
hldr.delete.setTag(position);
hldr.delete.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
int position = (int)v.getTag();
list.remove(position);
notifyDataSetChanged();
}
});

First.
You should make a object that stores all your different strings instead of using multiple arrays for each value.
Ej:
class MyClass
{
String id;
String name
String price;
public MyClass(String id, String name, String price)
{
this.id = id;
this.name = name;
this.price = price;
}
}
That way you wouldnt have to delete the position of each of the arrays.
And finally to answer your question, just delete the value of position you want to delete for each of the arrays.
Since they are Array and not ArrayList you will need to recreate it with the correct new dimension (Note it will be much easier with ArrayList).
Then just call notifyDataSetChanged() on your Adapter class.
Hope this helps.

How to get the value of clicked list item

I just want to get the value of clicked list item,
i.e if list contains apple,ball,cat, then clicked on apple then it gives value as apple, ,In the below code I am using inner class base adapter to display the data.
public class RecordsActivity extends Activity implements
OnItemClickListener
{
ListView listProduct;
ListAdapter adapter;

ArrayList<String >receipt=new ArrayList<String>();
ArrayList<String >balance=new ArrayList<String>();
ArrayList<String> week = new ArrayList<String>();
ArrayList<String> amount = new ArrayList<String>();
String get_name,get_date,Name;
String GetAmnt;

A few assumptions here, your actual fields do not need to be ArrayList's since each query returns a single row item from the db, i create a master object with Strings to represent the data...
So here is how i would do it, you need to re structure your data
First i would change your data to a :
public class ParentObject {
public String BILLDATE ;
public String BILLNO ;
public String PARTYNAME ;
public String BILLAMOUNT ;
public String RECEIPT ;
public String BALANCE ;
public String WEEK ;
public String AMOUNT ;
}
UPDATE
then i would change my Activity to:
public class RecordsActivity extends Activity implements OnItemClickListener{
ListView listProduct;
ListAdapter adapter;
TextView UserName,Date;
// your new parent object ArrayList, much cleaner
List<ParentObject> parentObjects;
String get_name,get_date,Name;
String GetAmnt;
Dialog dialog;
AlertDialog alertDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_records);
UserName=(TextView) findViewById(R.id.txt_disuser);
Intent usr=getIntent();
get_name=usr.getStringExtra("user");
UserName.setText(get_name);
Date=(TextView) findViewById(R.id.txt_disdate);
Intent dt=getIntent();
get_date=dt.getStringExtra("date");
Date.setText(get_date);
Intent id =getIntent();
Name=id.getStringExtra("name");
listProduct=(ListView) findViewById(R.id.ListViewFilledRecrd);
listProduct.setAdapter(adapter);
listProduct.setOnItemClickListener(this);
}
protected void onResume(){
getAllProduct();
super.onResume();
}
public void getAllProduct(){
SQLiteDatabase db = this.getDB();
Cursor c;
//c=db.rawQuery("SELECT * FROM RECORDS", null);
c=db.rawQuery("SELECT * FROM RECORDS WHERE PARTY_NAME = '" + Name + "' ", null);
String BILL_DATE,BILL_NO,PARTY_NAME,BILL_AMOUNT,RECEIPT,BALANCE,WEEK,AMOUNT;
if(c.moveToFirst()){
// initialize the parent arrayList
parentObjects = new ArrayList<ParentObject>();
do{
// initialize a single object
ParentObject parentObject = new ParentObject();
// fill in its data
parentObject.BILL_DATE = c.getString(1);
parentObject.BILL_NO=c.getString(2);
parentObject.PARTY_NAME=c.getString(3);
parentObject.BILL_AMOUNT=c.getString(4);
parentObject.RECEIPT=c.getString(5);
parentObject.BALANCE=c.getString(6);
parentObject.WEEK=c.getString(7);
parentObject.AMOUNT=c.getString(8);
// add it to your list
parentObjects.add(parentObject);
} while (c.moveToNext());
}
// pass the List<ParentObject> into your adapter
DisplyRecords dsptProd= new DisplyRecords(RecordsActivity.this, (ArrayList<ParentObject>)parentObjects);
listProduct.setAdapter(dsptProd);
listProduct.setOnItemClickListener(this);
c.close();
db.close();
}
private SQLiteDatabase getDB(){
String DB_NAME = "odsr.db";
return openOrCreateDatabase(DB_NAME, SQLiteDatabase.OPEN_READWRITE,
null);
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
// access to all your data through the parentObject
ParentObject data = (ParentObject) listProduct.getItemAtPosition(position);
// access all fields for this parent
Toast.makeText(RecordsActivity.this, "data: "+ data.BILL_DATE, + " ," + data.BILL_NO, " , etc", Toast.LENGTH_LONG).show();
}
}
and then update your Adapter to handle the List
class DisplyRecords extends BaseAdapter {
Context c;
List<ParentObject> parentObjects;
public DisplyRecords(Context context, ArrayList<ParentObject> parentObjects){
this.c=context;
this.parentObjects = parentObjects;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return parentObjects.size();
}
#Override
public Object getItem(int position) {
return parentObjects.get(position); // always return this parent
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(final int pos, View row, ViewGroup parent){
// You should implement the ViewHolder pattern, this is not doing that...
View child=row;
LayoutInflater layoutinflater;
if(child==null){
layoutinflater=(LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
child = layoutinflater.inflate(R.layout.list_product,null);
}
TextView txt_billdate=(TextView) child.findViewById(R.id.txt_bill_date);
TextView txt_billno=(TextView) child.findViewById(R.id.txt_bill_no);
TextView txt_partyname=(TextView) child.findViewById(R.id.txt_party_name);
TextView txt_billamt=(TextView) child.findViewById(R.id.txt_bill_amount);
TextView txt_receipt=(TextView) child.findViewById(R.id.txt_receipt);
TextView txt_balance=(TextView) child.findViewById(R.id.txt_balance);
TextView txt_wk=(TextView) child.findViewById(R.id.txt_week);
TextView txt_amount=(TextView) child.findViewById(R.id.txt_amount);
ParentObject parentObject = parentObjects.get(pos);
txt_billdate.setText(parentObject.BILLDATE);
txt_billno.setText(parentObject.BILLNO.);
txt_partyname.setText(parentObject.PARTYNAME);
txt_billamt.setText(parentObject.BILLAMOUNT);
txt_receipt.setText(parentObject.RECEIPT);
txt_balance.setText(parentObject.BALANCE);
txt_wk.setText(parentObject.WEEK);
txt_amount.setText(parentObject.AMOUNT);

My problem is i cant use this code segment in my adapter Class

Replace

with
if(theUrl==null || theUrl.equals("")){
and check if it works or not

Custom BaseAdapter wont add new Data - Android

I have a custom baseadapter that creates comment boxes. Everything works great on it until I want to add data. When I try to add the data it deletes the previous data and adds the new data. How do I make it so it keeps all the data? Is my Add method incorrect? Here is my baseadapter,
class CreateCommentLists extends BaseAdapter{

Setting the adapter:
final CreateCommentLists mycmlist = new CreateCommentLists(comments, usernames, numbers, DashboardActivity.this);
lstComments = (ListView)findViewById(android.R.id.list);
lstComments.setAdapter(mycmlist);
This is what how I call the add method,
mycmlist.add(comments,usernames,numbers);
mycmlist.notifyDataSetChanged();

In your add method you're setting the arrays to new values listComments = comments; That's replacing your old data with the new data.
You could use System.arrayCopy() to resize your listArrays to the new size and append the new items. A much less tedious approach, however, would be to store your arrays as List<String>, allowing you to add more items without worrying about resizing lists.
The result would look something like this...
public class CommentsAdapter extends BaseAdapter
{
private LayoutInflater inflater;
private List<String> comments;
private List<String> numbers;
private List<String> usernames;
public CommentsAdapter(Context context)
{
inflater = LayoutInflater.from(context);
comments = new ArrayList<String>();
numbers = new ArrayList<String>();
usernames = new ArrayList<String>();
}
public void add(String[] comments, String[] numbers, String[] usernames)
{
this.comments.addAll(Arrays.asList(comments));
this.numbers.addAll(Arrays.asList(numbers));
this.usernames.addAll(Arrays.asList(usernames));
notifyDataSetChanged();
}
#Override
public int getCount()
{
if (comments == null)
return 0;
return comments.size();
}
#Override
public String getItem(int position)
{
return comments.get(position);
}
#Override
public long getItemId(int position)
{
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
if (convertView == null)
{
convertView = inflater.inflate(R.layout.list_item, parent, false);
convertView.setTag(new ViewHolder(convertView));
}
ViewHolder holder = (ViewHolder) convertView.getTag();
holder.commentView.setText(comments.get(position));
//Other view bind logic here...
return convertView;
}
private static class ViewHolder
{
public TextView commentView;
public TextView numbersView;
public TextView usernamesView;
public Button usernameButton;
public Button numberButton;
public ViewHolder(View v)
{
commentView = (TextView) v.findViewById(R.id.listComment);
numbersView = (TextView) v.findViewById(R.id.listNumber);
usernamesView = (TextView) v.findViewById(R.id.listPostedBy);
usernameButton = (Button) v.findViewById(R.id.listUsernameButton);
numberButton = (Button) v.findViewById(R.id.listNumberButton);
}
}
}
I also highly recommend reading this page on the Android Developer's site: http://developer.android.com/training/improving-layouts/smooth-scrolling.html
Your current adapter implementation is very inefficient, and that page should help you iron out some kinks.

You probably need to add the String[] array to the existing one, instead of replacing it.
Add this function which joins two arrays (Sadly there is no already-implemented method for Java):
String[] concat(String[] A, String[] B) {
String[] C= new String[A.length + B.length];
System.arraycopy(A, 0, C, 0, A.length);
System.arraycopy(B, 0, C, A.length, B.length);
return C;
}

And then change the add method to this:
public void add(String[] comments, String[] usernames,
String[] numbers) {
listComments = concat(listComments, comments);
listUsernames = concat(listUsernames, usernames);
listNumbers = concat(listNumbers, numbers);
}
And you had a typo in your code. In the add method, the listUsernames and listNumbers should be swapped I think.. I fixed it for you.

how to iterate through each checkboxes in each row of a listview in android?

I have an application with three textviews and one checkbox in each row of a listview.what I want that on a click of a button I will be able to get the state of each checkbox and the row corresponding to (isChecked) checkboxes get deleted.one more thing my checkboxes are hardcoded in an xml file.I have searched a lot but couldn't find anything specific.thanks in advance.HERE IS MY CODE...
public class recentcalllistultimate extends ListActivity implements OnClickListener {

Try this:
Inside your getView(...) method...
final CheckBox lChk = ((CheckBox) pConvertView.findViewById(R.id.myChkBoxID));
private List<lisInfo> m_lisInfo = new ArrayList<lisInfo>();
lChk.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// Populate the listInfo with check box status
m_lisInfo.get(lPosition).setChkBoxStatus((isChecked));
}
});
public class lisInfo{
private boolean chkBoxStatus;
public boolean isChkBoxStatus() {
return chkBoxStatus;
}
public void setChkBoxStatus(boolean chkBoxStatus) {
this.chkBoxStatus = chkBoxStatus;
}
}
Now iterate the listInfo wherever required to get the check boxes statuses in the list view

maintain an array of boolean inside adapter . set listener on ckeckbox in getview which will swipe values of array on check/uncheck .
now make this array accesible in activity where on button
click()
{
for(int i=0;i<array.size;i++)
{
if(array[i])
adapter.deelet(item i);
//modify syntax
}
}
