activity class

package com.example.apps; import android.app.activity; import android.os.bundle; import android.view.view; import android.widget.button; import android.widget.edittext; public class deed extends activity { rest r=new rest(); @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); button save=(button)findviewbyid(r.id.save); save.setonclicklistener(onsave); } private view.onclicklistener onsave=new view.onclicklistener() { public void onclick(view v) { edittext name=(edittext)findviewbyid(r.id.name); edittext address=(edittext)findviewbyid(r.id.addr); r.setname(name.gettext().tostring()); r.setaddress(address.gettext().tostring()); } }; }

to create easy, let's alter onclick() like

save.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { // stuff here } });

where save button. on, edit question updated code easier read. having problem reading code in comment looks if alter should work you. here give-and-take different ways utilize onclick()

i going delete info may help others. however, pointed out @dymmeh setcontentview() isn't called there no layout button from. needs called appropriate layout, r.layout.your_layout before can reference views, buttons, edittext, etc...
