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

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

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

                android:bottomLeftRadius="4dp" 
                android:bottomRightRadius="4dp"
