Create a new resource folder named xml in the app folder Make use of ListPreference

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

    <ListPreference
        android:key="@string/pref_key"
        android:title="@string/pref_title"
        android:defaultValue="@string/pref_default"
        android:entryValues="@array/pref_values"
        android:entries="@array/pref_options"
        />

</PreferenceScreen>

Create a resource file name arrays.xml in values resource folder

<resources>
    <string-array name="pref_values" >
        <item>popular</item>
        <item>top rated</item>
    </string-array>
    <string-array name="pref_options" >
        <item>popular</item>
        <item>top rated</item>
    </string-array>
</resources>

The pref_values acts as the keys for the options. While the pref_options will be the visible options. The default should be either of top rated or popular

Hope this helps

u can add a radiobutton to preferencescreen.
pref.xml is the preference xml.

<PreferenceScreen
        android:key="prefkey"
        android:title="SETTINGS"
        android:summary="HELLO"
        />

Create a xml(radio.xml) with only radiobutton in it and place it in layout folder.

now in code:

onCreate(){  
PreferenceScreen root=getPreferenceScreen();  
addPreferencesFromResource(R.xml.prefs);   
PreferenceScreen pref= PreferenceScreen) root.findPreference("prefkey");   
pref.setWidgetLayoutResource(R.layout.radio);  

}

Radio buttons must be in groups that's why you should a listpreference first. If you want to add only one radio button then use checkbox instead ;)
