final RadioButton[] rb = new RadioButton[5];
final RadioGroup rg = new RadioGroup(this); //create the RadioGroup
rg.setOrientation(RadioGroup.VERTICAL);//or RadioGroup.VERTICAL
for(int i=0; i<5; i++){
rb[i] = new RadioButton(this);
rg.addView(rb[i]); //the RadioButtons are added to the radioGroup instead of the layout
rb[i].setText("Radio " + i);
}
ll.addView(rg);//you add the whole RadioGroup to the layout
btnWrite.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
