java - Passing parameters through AsyncTask - android -

i'm trying pass integer through asynctask use in doinbackground on click of button.

here passing parameters

public void go(view view) {      edittext input = (edittext)findviewbyid(r.id.txtinput);      int downloads = integer.parseint(input.tostring());      processtask mytask = new processtask();      //5000 - number of ms simulate download      mytask.execute(5000, downloads);  } 

and here try use same values pass

    private class processtask extends asynctask<integer, integer, void>{  @override protected void doinbackground(integer... params) {     // todo auto-generated method stub      integer myd = params[1];       for(int = 0; i<myd; i++){         try{             thread.sleep(params[0]);             publishprogress(i+1);         }catch (interruptedexception e){             e.printstacktrace();         }     }     return null; }

any , appreciated. i'm kind of new android.

you're missing gettext() call in method chaining.

it needs input.gettext().tostring().

the clue logcat output:

invalid int: "android.widget.edittext{...

that not input.

for number parsing, i'd recommend catching exception. way input might have forgotten filter not crash program.
