Swap positions of Radios - Android java -

i got 1 radiogroup 4 radios.

    radiogroup rg = (radiogroup) findviewbyid(r.id.radiogroup);      radiobutton r0 = (radiobutton) findviewbyid(r.id.radio0);     radiobutton r1 = (radiobutton) findviewbyid(r.id.radio1);     radiobutton r2 = (radiobutton) findviewbyid(r.id.radio2);     radiobutton r3 = (radiobutton) findviewbyid(r.id.radio3); 

i set text of them.

    r0.settext("1");     r1.settext("2");     r2.settext("3");     r3.settext("4"); 

so got radios 1, 2, 3, 4. how can randomly swap positions of radios. want 3,2,1,4 or 2,3,1,4....etc... important don't want change text of radios, said want positions swapped.

i don't think can achieve using same layout xml file.

use 4 different layouts, , inflate randomly.

all ids work if keep same in each xml file.

@override public void oncreate(final bundle bundle) {   super.oncreate(bundle);   setcontentview(randomlayout());    radiogroup rg = (radiogroup) findviewbyid(r.id.radiogroup);   // ... }  public static int randomlayout() {   final int n[] = { r.layout.layout1, r.layout.layout2, r.layout.layout3, r.layout.layout4 }   random random = new random();   return n[random.nextint(n.length)]; }
