RadioButton.setText() is not displaying the text

Question

I am creating RadioButtons and adding them to RadioGroup dynamically. But the text for the RadioButtons are not showing on the screen when I run the application.

This is my code for RadioButtons

else if ((items.get(i).toString()).equals("rad")) {
                RadioGroup bg = new RadioGroup(getApplicationContext());
                int child=0;
                for (int h = textlen; h < text.size(); textlen++) {

                    if (text.get(textlen).contains("(")) {

                        s = text.get(textlen).replace("(", "");

                        if (s.contains(")"))
                            s = s.replace(")", "");

                    } else if (text.get(textlen).contains(")")) {
                        s = text.get(textlen).replace(")", "");
                    } else
                        s = text.get(textlen);

                    RadioButton radioButton = new RadioButton(
                            getApplicationContext());
                    bg.addView(radioButton);
                    // / radioButton.setName("rbt");
                    if (s.contains("{on}")) {
                    //  radioButton.setSelected(true);
                        radioButton.setChecked(true);
                        s = s.replace("{on}", "");
                    } else {
                        radioButton.setChecked(false);
                        s = s.replace("{of}", "");
                    }
                    //((RadioButton)bg.getChildAt(child)).setText(s);
                    //child++;

                    radioButton.setText(s);

                    String c = text.get(textlen).substring(
                            text.get(textlen).length() - 1);
                    if (c.equals(")")) {
                        textlen++;
                        break;
                    }



                }

                layout.addView(bg);
            }

When I debug the code I can see that the text is added to RadioGropus children

But on running the application the text is not visible. Can any one please detect the issue. Thanks Alot

Simply add

setLayoutParams(params);

for both RadioButton as well as RadioGroup.

Where

android.widget.LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
            LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
