Can a radiogroup show a heading/title?

Question

I've installed a radiogroup with three radio buttons on my app, but I want text to apear above it like it does with checkboxes and such. Can I reference the strings.xml file like this?

   <RadioGroup
        android:id="@+id/set_radiogroup"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/between_games_timer"
        android:orientation="vertical"
        android:text="@string/sets_radio_group" >

        <RadioButton
            android:id="@+id/one_set"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">
            </RadioButton>
        <RadioButton
            android:id="@+id/two_sets"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">
            </RadioButton>
        <RadioButton
            android:id="@+id/three_sets"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">
            </RadioButton>            
    </RadioGroup>

Because when I run the app the three radio buttons appear without any text. Or is there an easier way?

Old question, but maybe my answer will help somebody.

One of the ways to add a header for all buttons, is to simply use TextView inside RadioGroup.

And of course, you can set text for each radio button. You should use android:text property to set text for each of buttons. I used usual strings in examples below, but you should better extract your strings into Strings.xml

Here is an example:

 <RadioGroup
    android:id="@+id/set_radiogroup"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    >

    <TextView
        android:id="@+id/header"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Choose one of three types:"
        />

    <RadioButton
        android:id="@+id/onse_set"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Type one"
        />
    <RadioButton
        android:id="@+id/two_sets"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Type two"
        />
    <RadioButton
        android:id="@+id/three_sets"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Type three"
        />
</RadioGroup>
