Add a button in my chat app

I have two source codes (of the same chat app). In one of the source codes there is a code for button placed at bottom right corner in chats screen. When you click the button a slam book question appears in the chat. I want the code for this button to copy paste in another source code. Also when one clicks the button the questions appear in an orderly form. I want random questions to be appeared everytime when one clicks the button. Daily limit of questions appearing in chat should be 12 per day per person for all the chats combined (the limit is 20 now in the code). Change the splash screen and update it on the play store.
