public class headeractivity extends activity { button b1,b2; /** called when activity first created. */ @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.headerfile); b1 = (button)findviewbyid(r.id.button1) ; b2 = (button)findviewbyid(r.id.button2) ; } //oncreate on public void first1(view v) { intent =new intent(this,firstactivity.class); startactivity(i); finish(); } public void second(view v) { intent i1 =new intent(this, secondactivity.class); startactivity(i1); finish(); } } but got error every time …
log-cat :
error/androidruntime(328): java.lang.illegalstateexception: not find method first1 (view) in activity class com.contactdetails.contactdetailsactivity onclick handler on view class android.widget.button id 'button1'
in contactdetailsactivity.java class should add below method
public void first1(view v) { // onlick code }
