Can I use 2 or more Layout in 1 Activity? : ***Hello!***
 I have ca. **30 Buttons** in an Activity (layout.xml (here are the buttons), mainActivity.java (here are the code).
 **So, my question is:** Can I use 30 different layout, for that 1 activity, or I have to make 30 different activity? I'd like to put all layout 2 gifs, and therefor I don't know how can I do this. Which option is the best, and if the first, how can I import to the layout or activity the gifs? 
Thanks for the answers! (Sorry for my bad English)
