i getting above error in following code in button , edittext. don't know why coming. if guys can understand , tell me went wrong here, great.

import android.app.activity; import android.content.intent; import android.net.uri; import android.os.bundle; import android.view.view; import android.widget.button; import android.widget.edittext;  public class activity2 extends activity {      public void oncreate(bundle savedinstancestate)     {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity2);          button btn = (button) findviewbyid(r.id.btn_ok);         btn.setonclicklistener(new view.onclicklistener() {              @override             public void onclick(view v) {                 intent data = new intent();                  edittext txt_username = (edittext) findviewbyid(r.id.txt_username);                 data.setdata(uri.parse(txt_username.gettext().tostring()));                 setresult(result_ok, data);                 finish();             }         });      }  }

i have tried see in link the method setonclicklistener(new view.onclicklistener(){}) undefined type imagebutton1 not usable me.

you have typo:

is edittext txt_username = (edittext) findviewbyid(r.id.txt_username);

not edittext txt_username = (edittext) findviewbyid(r.id.txt_username);

the last letter, d, lowercase

i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
