Done.

+        android:textColor="?android:attr/textColorPrimary"
+        android:textSize="14sp" />
+    <TextView

[Theresa, 2017/04/03 15:05:20]

nit: blank line above this one and the other <TextView below

[megjablon, 2017/04/03 20:33:44]

Done.

+        android:id="@+id/site_data_used"
+        android:layout_height="wrap_content"
+        android:layout_width="wrap_content"
+        android:gravity="end"
+        android:paddingBottom="10dp"
+        android:paddingTop="10dp"
+        android:paddingStart="10dp"

[Theresa, 2017/04/03 15:05:20]

nit: Can this be paddingStart 10dp w/ no paddingEnd on the previous TextView for
consistency with the TextView below.

[megjablon, 2017/04/03 20:33:44]

Done.
