android - Listener for RadioButton for change Fragments -

i need switch fragments @ application tabs (radiobutton). event listener should use? onclick or oncheckedchanged? if possible example

for single radiobutton can use onclicklistener follows:

         onclicklistener listener = new onclicklistener() {                @override                public void onclick(view v) {                       radiobutton rb = (radiobutton) v;                       toast.maketext(your_activity.this, rb.gettext(),                        toast.length_short).show();                }          };           radiobutton rb1 = (radiobutton) findviewbyid(r.id.radiobutton1);          rb1.setonclicklistener(listener); 

in case of radiogroup need use oncheckedchangelistener follows :

    radiogroup radiogroup = (radiogroup) findviewbyid(r.id.yourradiogroup);      radiogroup.setoncheckedchangelistener(new oncheckedchangelistener()      {         public void oncheckedchanged(radiogroup group, int checkedid) {             // checkedid radiobutton selected              switch(checkedid) {                   case r.id.radiobutton1:                        // switch fragment 1                                        break;                   case r.id.radiobutton2:                       // fragment 2                       break;                   case r.id.radiobutton3:                       // fragment 3                       break;             }            }     });  

the oncheckedchanged callback receives id of newly checked button in checkedid parameter.
