<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
Code:
public class MainActivity extends Activity {
private checkBox1,checkBox2;
private Button btn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btn = (Button) findViewById(R.id.button1);
checkBox1 = (CheckBox) findViewById(R.id.checkBox1);
checkBox2 = (CheckBox) findViewById(R.id.checkBox2);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
StringBuffer result = new StringBuffer();
result.append("checkBox1 : ").append(checkBox1.isChecked());
result.append("checkBox2 : ").append(checkBox2.isChecked());
Toast.makeText(MainActivity.this, result.toString(),
Toast.LENGTH_LONG).show();
}
});
}
}
I hope this will help you.

Radiobutton in wikipedia says
A RadioButton or option button is a type of graphical user interface element that allows the user to choose only one of a predefined set of options.
You would have to just use checkboxes instead of radio button for allowing multiple options to be selected,else you are doing something which is inherently wrong in a UI be it mobile/web.
If still want to use RadioButtons, don't put them all in a RadioGroup. Either put them in several groups or manage them yourself completely.

You can try the layout as follows :
None of the Radio buttons will be selected at launch, but you can select them individually.
You just had to put them outside RadioGroup.
But You won't be able to de-select those Radio buttons, if selected mistakenly.
Checkboxes are a Proper way to go for such a thing.
