I'm developing an Android 3.1 Tablet application and asking this here because I haven't found any working answer (or example) in my code.
I have the following piece of code:

I'm trying to center radio buttons inside radiogroup but I don't know how to do it.
I have tried this code:
<RadioGroup
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="center|left"/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|right" />
</RadioGroup>
But it doesn't work.
How can I do it?

Based on research from the Neilson Norman Group as well as the various human interface guidelines for Apple and Microsoft, radio buttons should have the circle to the left of the label, and the list should be stacked vertically.
Use the android:orientation="horizontal" -attribute of the RadioGroup.
Use the GroupName property to specify a grouping of radio buttons to create a mutually exclusive set of controls. You can use the GroupName property when only one selection is possible from a list of available options. When this property is set, only one RadioButton in the specified group can be selected at a time.
It might help to try this: Align your radio group to center
<RadioGroup
android:id="@+id/rGroupResSzOnline"
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_weight=".07"
android:gravity="center"
android:orientation="horizontal" >
<RadioButton
android:id="@+id/rResSzOnlineYes"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="Yes" />
<RadioButton
android:id="@+id/rResSzOnlineNo"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="No" />
</RadioGroup>
