can me give sample code? thank's
this 1 template. hope help.
public class myactivity extends activity implements view.onclicklistener { button button1, button2, button3; @override public void oncreate(bundle bundle) { super.oncreate(); ... button1 = (button) findviewbyid(r.id.button1); button2 = (button) findviewbyid(r.id.button2); button3 = (button) findviewbyid(r.id.button3); button1.setonclicklistener(this); button2.setonclicklistener(this); button3.setonclicklistener(this); } @override public void onclick(view v) { switch(v.getid()) { case r.id.button1: // stuff; can called method here also. break; case r.id.button2: // stuff; break; ... } } you can set in layout xml using android:onclick attribute.
android:onclick="onclick" then in activity class add onclick method.
public void onclick(view v) { //write code here if(v.getid==r.id.button1 || v.getid==r.id.button2 || v.getid==r.id.button3 ||v.getid==r.id.button4){ // stuff } }
