i'm new android development. here's problem ran into. i'm using android studio. looked on many sites, said import related class. having done that, problem remains. appreciated.

can please me this, have been searching while solution.

here's code:

package com.example.veeresh.myapplication; //import statements import android.support.v7.app.actionbaractivity; import android.os.bundle; import android.view.menu; import android.view.menuitem; import android.widget.button; import android.view.view; import android.widget.textview;  public class mainactivity extends actionbaractivity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          button button1 = (button)findviewbyid(r.id.button1);          button1.setonclicklistener(                 //error: cannot find symbol class onclicklistener                 new button.onclicklistener()                 {                     public void onclick(view v)                     {                         textview text1 = (textview)findviewbyid(r.id.text1);                         text1.settext("veeresh here");                     }                 }                 );     } } 

error:

error:(24, 27) error: cannot find symbol class onclicklistener
error:execution failed task ':app:compiledebugjava'.
compilation failed; see compiler error output details.

it should new view.onclicklistener() instead of new button.onclicklistener()

onclicklistener capital o.
