Code to create dotted lines with EditText that expand/compress based on entered/deleted text,in Android

Here ima using two views.This code will cover,how to expand firstview based on second view size..
In second view we enter data,based on the entered text second view will expand..and every time first view also changed based on second view height..

i implemented this in my AddJobScreen class of SnailMail(Latterly)  Project
