this simple method don't know code mean this

     button1 = (button)findviewbyid(r.id.b1);      button2 = (button)findviewbyid(r.id.b2);      button3 = (button)findviewbyid(r.id.b3);      button4 = (button)findviewbyid(r.id.b4);      //button1-button4.setonclicklistener(new view.onclicklistener() {            public void onclick(view button1-4){             {              //do same method button1-4             }           }         });       button5 = (button)findviewbyid(r.id.b5);      button6 = (button)findviewbyid(r.id.b6);      button7 = (button)findviewbyid(r.id.b7);      button8 = (button)findviewbyid(r.id.b8);      //button5-button8.setonclicklistener(new view.onclicklistener() {            public void onclick(view button5-8){             {              //do same method button5-8             }           }         });       button9  = (button)findviewbyid(r.id.b9);      button10 = (button)findviewbyid(r.id.b10);      button11 = (button)findviewbyid(r.id.b11);      button12 = (button)findviewbyid(r.id.b12);      //button5-button8.setonclicklistener(new view.onclicklistener() {            public void onclick(view button9-12){             {              //do same method button9-12             }           }         });

so have 12 button on project put in 3 group(layout), each group have 4 button inside mean 4 button in each group same thing.

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  } }
