                android:singleLine="true"
                android:inputType="textEmailAddress"

   <LinearLayout android:layout_width="fill_parent"
                 android:layout_height="wrap_content" android:orientation="horizontal"
                 android:paddingLeft="10dp">
      <TextView android:text="Initial" android:textColor="#686868"

      android:layout_height="match_parent">

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

   <padding android:left="1dp"
            android:top="1dp"
            android:right="1dp"
            android:bottom="1dp"
         />

   <corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp"
            android:topLeftRadius="7dp" android:topRightRadius="7dp"/>

</LinearLayout>
