I have 4 RadioButtons (part of same RadioGroup) and I want to align them like this :

Code I am using is :

```
    <RadioGroup
        android:id="@+id/add_reminder_type"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="horizontal" >

        <LinearLayout
            android:layout_width="@dimen/zero"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center_horizontal"
            android:orientation="vertical" >

            <RadioButton
                android:id="@+id/add_reminder_daily"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/add_reminder_daily" />

            <RadioButton
                android:id="@+id/add_reminder_weekly"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/add_reminder_weekly" />
        </LinearLayout>

        <LinearLayout
            android:layout_width="@dimen/zero"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center_horizontal"
            android:orientation="vertical" >

            <RadioButton
                android:id="@+id/add_reminder_monthly"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/add_reminder_monthly" />

            <RadioButton
                android:id="@+id/add_reminder_yearly"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/add_reminder_yearly" />
        </LinearLayout>
    </RadioGroup>

```

But by using this code, **RadioGroup loses its property and all the RadioButtons can be checked at same time**.

**Any idea how RadioGroup can retain its property** using this type of alignment ?
