I have added 2 RadioButtons under RadioGroup and enabled first one, when i selecting second one its not deselecting first one. can you suggest me what was the wrong in this

Here is my xml:

<RadioGroup 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:orientation="horizontal">
        <RadioButton 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:checked="true"
            android:text="NO"/>
        <RadioButton 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="YES"/>

            android:checked="true"
            android:text="NO"/>
