Android App Redesign

I need a GUI-Code redesign of a my app. 'Nuovo Codice della Strada', published by Kineo. So, I need a Tab-based app, with the following views: 1 - Article List View - A simple list with the article header taken from the DB. The first row must contain a search field. The hw 'option button' must show a menu with the 'preferred', when clicked the list must show only the preferred articles. 1.1 - Single Article View Must show the content of the single article. The hw 'option button' bust show three options, 'set as preferred', 'send via mail', 'add note'. The hw 'back button' must show the 'Article List View' 2 - Segnali List View like the 1, but the list must show also a small icon 2.1 - like 1.1 but with an image other than the text 3 - Credits View - A simple scrolling text 4 - Punti View - a simple list, not clickable. Each screen must show an admob banner, under your choose to implement the code in each view or only on the main one. As said, all the code is yet written, a need some changes about the hw buttons, to remove the options from top bar. And a better organization. For example the view 1 and 1.1 must be reusable (In the app paid version I have two of these view set). According to this view, in my iPhone app, I have a main class, that manage the TAB, where different tab are added, simply with the specification of tabName, TabIcon, databaseFileName.
