Many Editext in array

Question

I have 20 edittext,layout and autocompletetextview I want to access them and everything using arrays I am getting an error right on attaching their ids. Where am I going wrong here

  LinearLayout[] laygroup ;
  EditText[] etquantity,etprice ; 
  AutoCompleteTextView[] etproduct ; 
  int[] laygroupid = new   int[]{R.id.laygroup0,R.id.laygroup1,R.id.laygroup2,R.id.laygroup3} ;
  int[] etquantityid = new int[]{R.id.autoquantity0,R.id.autoquantity1,R.id.autoquantity2,R.id.autoquantity3};
  int[] etpriceid = new int[]{R.id.autoprice0,R.id.autoprice1,R.id.autoprice2,R.id.autoprice3} ;
  int[] productid = new int[] {R.id.autoproduct0,R.id.autoproduct1,R.id.autoproduct2,R.id.autoproduct3};

then in the oncreate

  for(int i=0; i<=3; i++) 
    { 
    etprice[i] = (EditText)getActivity().findViewById(etpriceid[i]);
    etquantity[i] = (EditText)getActivity().findViewById(etquantityid[i]);
    laygroup[i] = (LinearLayout)getActivity().findViewById(laygroupid[i]) ;
    etproduct[i] = (AutoCompleteTextView)getActivity().findViewById(productid[i]); 
    }  

Answer 1

Try this..

You have to initialize the size arrays.

  LinearLayout[] laygroup = new LinearLayout[3];
  EditText[] etquantity = new EditText[3];
  EditText[] etprice = new EditText[3]; 
  AutoCompleteTextView[] = new etproduct EditText[3];
