android - unable to set properties of editText -

i defining edittext array in class outside methods.

i want use first member of edittext[] in oncreate method. have define again in oncreate method set properties of edittext.

edittext items[]=new edittext[30]; edittext rates[]=new edittext[30]; edittext quants[]=new edittext[30];  int no,id; @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);       setcontentview(r.layout.activity_main);      items[0].sethint("enter item");     items[0].setid(0); 

you've declared new array, haven't added objects it. need this:

items[0] = new edittext(this); items[0].sethint("enter item"); items[0].setid(0); 

this assigning value @ items index 0 new edittext object, otherwise value @ items[0] null.
