Question

How can i retrieve the text of a dynamically created radio button
selected by the user? Here’s my code:

RadioGroup radiogroup = (RadioGroup) findViewById(R.id.rdbGp1); 
        // layout params to use when adding each radio button 
        LinearLayout.LayoutParams layoutParams = new 
RadioGroup.LayoutParams( 
                RadioGroup.LayoutParams.WRAP_CONTENT, 
                RadioGroup.LayoutParams.WRAP_CONTENT); 
 for (int i = 0; i < 4; i++){ 
            final RadioButton newRadioButton = new RadioButton(this); 
            c3 = db.getAns(3); 
        for (int j=0;j<i;j++) 
            c3.moveToNext(); 
           label = c3.getString(0); 
        newRadioButton.setText(label); 
        newRadioButton.setId(6); 
        radiogroup.addView(newRadioButton, layoutParams);

Surprised there isn’t an easier way. If you are going to do something special though based on which button you should probably checked the ID instead of the Label.

radiogroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
         void onCheckedChanged(RadioGroup rg, int checkedId) {
              for(int i=0; i<rg.getChildCount(); i++) {
                   RadioButton btn = (RadioButton) rg.getChildAt(i);
                   if(btn.getId() == checkedId) {
                        String text = btn.getText();
                        // do something with text
                        return;
                   }
              }
         }
    });
