java - OnClick listener implementation not workin -

i'm using onclick() method implementing onclicklistener class. using below code not work! there no errors doesn't work. when click on button nil happens. can tell me wrong?

package com.behnam.phonech.main; import android.app.activity; import android.os.bundle; import android.util.log; import android.view.view; import android.view.view.onclicklistener; import android.widget.button; import android.widget.edittext; import android.widget.textview; public class mainactivity extends activity implements onclicklistener { edittext mainet; textview maintv; button mainbtn; button mainbtn2; string vaje; javab javab; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.main); mainet = (edittext) findviewbyid(r.id.edittext1); maintv = (textview) findviewbyid(r.id.textview1); mainbtn = (button) findviewbyid(r.id.button1); mainbtn2 = (button) findviewbyid(r.id.button2); vaje = new string(); javab = new javab(); } @override public void onclick(view aaaaa) { switch (aaaaa.getid()) { case r.id. log.i("mylog", "start button1"); vaje = mainet.gettext().tostring(); maintv.settext(javab.startj(vaje)); break; case r.id.button2: int c = 3; break; } } }

you never set listener on buttons

mainbtn.setonclicklistener(this);

you need add together of buttons want utilize onclick().

see answer different ways of handling onclick()

java android onclicklistener
