package com.jcw.andriod.fileListView;/*
 * Created by Jackson Woodruff on 18/07/2014 
 */*w  w  w.j a  v  a2s  . c om*/
 * This is a view with a few utility methods
 * that basically contains a FileListView.
 * It is designed for the selection of an
 * existing file (I designed it for opening
 * files)
 *
 * For file selection that enables the selection
 * of uncreated files, use the FileSaveView
