button - How to pass data from function to external object (android) -


im using impimentation of zyxel barcode scanner , want pass string 'upc' edittext object out of function, how can this?

 protected void onactivityresult(int requestcode, int resultcode, intent data)  {     switch(requestcode)      {         case intentintegrator.request_code:         {             if (resultcode != result_canceled)                  {                             intentresult scanresult = intentintegrator.parseactivityresult(requestcode, resultcode, data);                             if (scanresult != null)                             {                             string upc = scanresult.getcontents();                              }                 }                 break;                 }             }         }

second question:

i want call function after clicking button this:

button3.setonclicklistener(new onclicklistener()     {          @override         public void onclick(view v)         {               intentintegrator.initiatescan(this);          }     });

but error:

"the method initiatescan(activity) in type intentintegrator not applicable arguments (new view.onclicklistener(){})"

so ive tried solve problem calling function when clicking button funtction call original function

it's this:

 button3.setonclicklistener(new onclicklistener()     {          @override         public void onclick(view v)         {              turntheshiton();          }     });   public void turntheshiton() {     intentintegrator.initiatescan(this); }

but it's not real elegant way solve out, there other way?

thanks!!

 string upc = scanresult.getcontents();  updateeditfield(upc );// or use <activity-name>.this.updateeditfield(upc );     private void updateeditfield(string str){  editfield ef = (editfield)findviewbyid(r.id.<ef_id>);          if(null!=ef){            ef.settext(str):       } }

second question:

in intentintegrator.initiatescan(this);    use <activity-name>.this activity.this
