android - Difference between content_main.xml and activity_main.xml?

Question

I am new to Android App development. I have Android Studio 1.4. In my layout folder I have two XML files (content_main.xml and activity_main.xml). I have been following Bucky's tutorial and he just has the activity_main.xml. Which one should I use?

Answer 1

Unlike previous version, the new API 23 comes with the coordinatorLayout and stuff and just to make them simple to use android has distinguished activity's layout into two different layout i.e. content_main.xml & activity_main.xml.

I'll explain what they are for:

1. activity_main.xml

this xml file is used to display coordinatorLayout, tabLayout, floatingActionButton, viewPager etc..

2. content_main.xml

This xml file is use to display your stuff i.e. what you want to display to users.

So, if you are just asking in which xml you have to put your stuff, content_main.xml is the one....
