adding corners to my tabs background in android coding-CodePudding

I was implementing a drawable file to add a background to my tabs but i want it to have corners . I've used a shape and corners tags all embedded into a selector tag but it has no effects to my background corners . May I please get your help ? here's the code i've implemented :

    <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/bleue_sky" android:state_selected="true">
        <shape android:shape="rectangle">
            <corners
                android:bottomLeftRadius="15dp"
                android:bottomRightRadius="15dp"
                android:topLeftRadius="15dp"
                android:topRightRadius="15dp"
                />

        </shape>
    </item>
    <item android:drawable="@color/blackTransparent"/>

</selector>
