Try this solution for retrieving the text:

<pre><code>radiogroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

 void onCheckedChanged(RadioGroup rg, int checkedId) {
 for (int i = 0; i &lt; rg.getChildCount(); i++) {
 RadioButton btn = (RadioButton) rg.getChildAt(i);

 // do something with text

I have created two radio buttons in a radio group dynamically and one of them is checked.
I need when i cheked another button then its value should be saved in string.
But i have implemented <code>checkedchangelistener</code> for this.But its not working first time.
Here is my code.

<pre><code>rg = ((RadioGroup)getActivity().findViewById(alist_id.get(i)));
rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener(){
 public void onCheckedChanged(RadioGroup rd, int checkedId) {
 for(int i=0; i&lt;rd.getChildCount(); i++) {
 radio_button = (RadioButton) rd.getChildAt(i);
 int id = radio_button.getId();
 if(radio_button.getId() == checkedId) {
 text = radio_button.getText().toString();
 flag=true;
 System.out.println("trueeeeeeeee"+text);
 return;
 }
 }
 }
});
if (flag==true) {
 updated_list.add(text);
 System.out.println("sssssssssssssssssss");
}else {
 updated_list.add(data_from_list_view.get(i));
 System.out.println("falseeeeeee");
}
</code></pre>
