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.

To get all data from the list,
You need to create global adapter as
MyAdapter mAdapter;
onClick event of button by following code to get all data
for(Inforowdata row : mAdapter){
//All rows adata here....
}
or
for(int pos=0;mAdapter.getItemCount()-1;pos++)
mAdapter.getItem(pos)//All rows adata here....

Adapter selecting issue

I have a ListView which extends BaseAdapter. I have a array list. The ListView inflates and populates correctly. I am using the flipper view to change the layout to another but the problem is when i clicked on the first item it rotate but the item at third or sixth row will also rotate
list view how can i fix it i only want the image is change of selected item
ArrayList<product_data> al=new ArrayList<product_data>();

when i click on the first item it rotate and another view is coming
but when i scrolled the fourth item in below image will also rotate
i am using the on click listner on the relative views as in the code

Use ViewHolder for fill adapter. that may solve your issue
Example Code
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater mInflater = LayoutInflater.from(context);
final ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(
R.layout.news_by_categories_content, null);
holder = new ViewHolder();
holder.strNewsTitle = (TextView) convertView
.findViewById(R.id.txtNewsByCategories);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
NewsListByCategoriesItem obj = new NewsListByCategoriesItem(); // My Model class getting value from this
obj = newsArray.get(position);
holder.strNewsTitle.setText(obj.getStrNewsTitle());
return convertView;
}
class ViewHolder {
TextView strNewsTitle;
}
}

How to store information across Activities while using Tabs in Android

I have made an app in which i am using Two Tabs,
First Tab, to show list of Products [Menu Tab]
Second Tab, to show products added by you [Cart Tab]
Here i am allowing user to add products to cart, update quantity for product and show total amount of all the Items.
In my code i am facing very small problem but i am not getting any way for last two days to resolve this.
Problem:
Whenever i do click on Cart Tab to view products, those i have selected to buy and then again move back to Menu Tab to select few more products to buy and then again do click on Cart Tab to view all products i have selected, Here i am able to view Selected Product but not able to view updated quantity and not getting any change in Total Amount [Getting total of all previous added items only, not for those i have added second time...]
Please tell me where i am missing, to get updated quantity and to get change in total price, what code i need to add and where i need to add in my ViewCartActivity class
ViewCartActivity.Java:
public class ViewCartActivity extends Activity {
TextView mTxtViewGrandTotal;
String mGrandTotal ;
#Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.viewcartactivity);
ListView mLstView1 = (ListView) findViewById(R.id.listView1);
mTxtViewGrandTotal = (TextView) findViewById(R.id.mTxtViewGrandTotalValue);
ViewCartAdapter mViewCartAdpt = new ViewCartAdapter(ViewCartActivity.this);
mLstView1.setAdapter(mViewCartAdpt);
if (Constants.mItem_Detail.size() > 0)
{
Double mGTotal = Double.parseDouble(Constants.mItem_Detail.get(0).get(SingleProductActivity.KEY_TOTAL));
for (int i = 1; i < Constants.mItem_Detail.size(); i++) {
mGTotal = mGTotal + Double.parseDouble(Constants.mItem_Detail.get(i).get(SingleProductActivity.KEY_TOTAL));
}
mGrandTotal = String.valueOf(mGTotal);
mTxtViewGrandTotal.setText(mGrandTotal);
ImageButton mImgViewCart = (ImageButton) findViewById(R.id.back_btn);
mImgViewCart.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent mViewCartIntent = new Intent(ViewCartActivity.this, com.version.bajrang.january.menu.ArrowsActivity.class);
startActivity(mViewCartIntent);
}
});
}
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
System.out.println("onResume list current size "+Constants.mItem_Detail.size());
super.onResume();
}
}
In Logcat, i am getting:
onResume list current size 3 [Number of Records]
TabActivity.Java:
private void setTabs()
{
addTab("Order", R.drawable.tab_order, CategoryActivity.class);
addTab("Cart", R.drawable.tab_cart, ViewCartActivity.class);
}
#Override
public void onBackPressed() {
// Code to update product Quantity
super.onBackPressed();
Constants.mItem_Detail.clear();
}
ViewCartAdapter.Java:
public class ViewCartAdapter extends BaseAdapter {
Activity activity;
LayoutInflater inflater;
public ViewCartAdapter(Activity a) {
// TODO Auto-generated constructor stub
activity = a;
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
// TODO Auto-generated method stub
return Constants.mItem_Detail.size();
}
public Object getItem(int position) {
//return position;
return Constants.mItem_Detail.get(position);
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.viewcartlist, null);
TextView title = (TextView) vi.findViewById(R.id.title);
TextView qty = (TextView) vi.findViewById(R.id.qty);
TextView cost = (TextView) vi.findViewById(R.id.cost);
HashMap<String, String> item = new HashMap<String, String>();
item = Constants.mItem_Detail.get(position);
// Setting all values in listview
title.setText(item.get(SingleProductActivity.TAG_NAME));
qty.setText(item.get(SingleProductActivity.KEY_QTY));
cost.setText(item.get(SingleProductActivity.TAG_DURATION));
return vi;
}
}

Rakesh you have written everything needed in your program, just need to move from onCreate() to onResume() Method in ViewCartActivity
Like this:
public class ViewCartActivity extends Activity
{
TextView mTxtViewGrandTotal;
String mGrandTotal ;
#Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.viewcartactivity);
ListView mLstView1 = (ListView) findViewById(R.id.listView1);
mTxtViewGrandTotal = (TextView) findViewById(R.id.mTxtViewGrandTotalValue);
ViewCartAdapter mViewCartAdpt = new ViewCartAdapter(ViewCartActivity.this);
mLstView1.setAdapter(mViewCartAdpt);
ImageButton mImgViewCart = (ImageButton) findViewById(R.id.back_btn);
mImgViewCart.setOnClickListener(new OnClickListener()
{
public void onClick(View v) {
// TODO Auto-generated method stub
Intent mViewCartIntent = new Intent(ViewCartActivity.this, com.version.bajrang.january.menu.ArrowsActivity.class);
startActivity(mViewCartIntent);
}
});
}
#Override
protected void onResume()
{
super.onResume();
System.out.println("onResume list current size " + Constants.mItem_Detail.size());
if (Constants.mItem_Detail.size() == 0)
{
return;
}
Double mGTotal = Double.parseDouble(Constants.mItem_Detail.get(0).get(SingleProductActivity.KEY_TOTAL));
for (int i = 1; i < Constants.mItem_Detail.size(); i++)
{
mGTotal = mGTotal + Double.parseDouble(Constants.mItem_Detail.get(i).get(SingleProductActivity.KEY_TOTAL));
}
mGrandTotal = String.valueOf(mGTotal);
mTxtViewGrandTotal.setText(mGrandTotal);
}
}
