Try this

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item><shape>
            <stroke android:width="1dp" android:color="#000000" />

            <solid android:color="@android:color/transparent" />

            <corners 
                android:bottomLeftRadius="4dp" 
                android:bottomRightRadius="4dp" 
                android:topLeftRadius="4dp" 
                android:topRightRadius="4dp" />
        </shape></item>

</selector>
