Once a view is inflated dynamically as a list with a button attached to each row. How do I pass a row id to each of these buttons?

I have a list, this list is basically TableRows in scrollview which I have inflated with layout inflater, i.e. it depends at runtime, how many rows are being added. Now I have a button also attached in each row. This button is either a delete button or an edit button. Before programming I was thinking that I will just get the row id and call my delete function for that row id. But now when I program I see that I do not find a way to get the row id, because the button is just the same button always and how will button come to know with what row exactly it is linked to. I am basically doing database programming where I have taken lots of user input and displayed it in a table row inside a scroll view. But I don't know how do I get those rows. As of now I am not using any array list or array adapter. Do I need to use them either to solve my this problem ? Please help.
I am entering the my code here 

   if(dbExists)
    {
        myName = (TextView)findViewById(R.id.myName);
        db.open();
        Cursor c = db.getAllTitles();
        long NoOfRows = c.getCount(); //here I am gettin 30 as entered in database
        while(NoOfRows >= 1)
        {
             c.moveToFirst();

            //.........Inflate here name and number........
             LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
             View inflated = inflater.inflate(R.layout.name, myTableLayout);

             TextView userName = (TextView)findViewById(R.id.myName);
             userName.setText(c.getString(1));//here I am settng the user entered name

             Button delButton = (Button)rowView.findViewById(R.id.Delete_Name);
             delButton.setTag(RowId--);
             delButton.setOnClickListener(this);

             c.moveToNext();
             NoOfRows--;
        }
         db.close();
    }
   @Override
public void onClick(View v) {
    Long rowId = (Long)v.getTag(); 
    if (rowId != null) 
    {
       Toast.makeText(this, "rows get Tag() " + rowId, Toast.LENGTH_LONG).show();
        //db.deleteTitle(rowId); 
    } 

}

You can use setTag/getTag on a View so set and get special information for that view.

Using this you would call button.setTag(rowId) and then retrieve it later using getTag in your onClick method.

Here is a detailed answer with a code example.
