    private int i;

    private int hasOpen = 0; // 0 : Close(Basic), 1 : Open

Answer 1

Use this library to add Floating Action button with sub menus. fab-speed-dial

Now simple use setOnTouchListener on single main floating button , you wont have to worry about all the sub menus.

Hope this helps :)
