package com.d.da; import android.app.activity; import android.os.bundle; import android.widget.button; public class pageone extends activity { button button1; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.abus); } }
you didn't add onclicklistener button on second activity
edit:
package com.d.da; import android.app.activity; import android.os.bundle; import android.widget.button; public class pageone extends activity { button button2; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.abus); addlisteneronbutton(); } public void addlisteneronbutton() { final context context = this; button2 = (button) findviewbyid(r.id.abus2); button2.setonclicklistener(new onclicklistener() { @override public void onclick(view arg0) { intent intent = new intent(context, mainactivity2.class); startactivity(intent); } }); } }
