You can use the <RadioGroup> to group the Radio buttons like this;

<RadioGroup 
    android:id="@+id/radioGroup"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <RadioButton
        android:id="@+id/Red"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/red"
        android:textColor="@android:color/holo_red_dark" 
        android:onClick="onRadioButtonClicked" />

    <RadioButton
        android:id="@+id/Green"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/green"
        android:textColor="@android:color/holo_green_dark"
        android:onClick="onRadioButtonClicked"/>

    <RadioButton
        android:id="@+id/Blue"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/blue"
        android:textColor="@android:color/holo_blue_dark"
        android:onClick="onRadioButtonClicked"/>

</RadioGroup>
