Android Prototype App

I need an urgent help for a test Android App. We have almost done a prototype for an app and we need to put a simple logic inside the app. All the graphics/interface is done.. the only thing we need to implement is: We need the following: * When user clicks on the button "Save" it should save the entry on the database. * After the save it should return to a listview, where all the entries can be seen and when user click on an entry, it should show the selected item and below that there will be two buttons "delete" & "edit". If the user click "delete" there will be a dialogbox asking confirmation... if the user click the edit button should bring back to the edit mode where the user can edit/update the fields (only two fields.. heading & content) after save it should bring back to the list view. We have all the source codes for the project. We need to fix this as soon as possible, so pls. act quickly.
