You can do the following:

//Get your string   
String dt=q.showquestionpapeda(i);
// First split on basis of '/'
String [] firstSplit = dt.split("/");
// Get the second element consisting of "Answer1,Answer2,Answer3" string and split based on ","
String [] secondSplit = firstSplit[1].split(",");

//get the radio group and set the text of first second and third radio button
RadioGroup rbtnGrp = (RadioGroup)findViewById(R.id.radioGroup1);
for (int i = 0; i < rbtnGrp.getChildCount(); i++) {
    // setting the text on the three children with three strings in the array
    ((RadioButton) rbtnGrp.getChildAt(i)).setText(secondSplit[i]); 
}

You can also set the text outside loop for each of them individually. Hope this helps.

you have to do something like the following :

// this get the number of radioButtons inside the radioGroup
int count = radioGroup.getChildCount();
// this is what you are doing to split your quesitons 
 String[] quest=dt.split("/");

//here we loop through all the child radioButtons 
    for (int i=0;i<count;i++) {
//get the radio button at the index i
        View o = radioGroup.getChildAt(i);
//if the view is a RadioButton 
        if (o instanceof RadioButton) {
            o.setText(quest[i]);
        }
    }

and please give me somefeed back

Hope that helps .
