Codez une application Android

Hello, I need to add 2 new simple functions to application (it's a joke/quote app) : Function 1 : when the user goes to the quotes/jokes page, he can scroll down to navigate and see all the quotes/jokes, each page can show maximum 50 quotes/jokes, the user can switch to other pages thanks an arrow at the top, allowing him to choose the desired page to show. see this image to understand : [login to view URL] (look at the arrow at the top) when clicked it shows this : [login to view URL] What i want is to change to the arrow to a page switcher : a drop menu that change the page. something like this : [login to view URL] In a few words, it's a simple task i just want to stylish it :) Function 2 : 1. My app has currently an admob banner at the top : see this image : [login to view URL] .. i just want to take it to the bottom of the screen : that's better 2. i want to add admob interstitial ads (full screen ads), they should be shown each time the user has seen X number of quotes/jokes These are 2 simple tasks, i want them to get done as soon as possible, the lower you bid the more chances you have to get hired. Happy bidding.
