Answer 1

If you have given the id to the include element and you have only single view in the included layout (not in any ViewGroup), in my case AdView, then use the id of include element instead of included view.

activity_main.xml

In activity

AdView nullAdView=findViewById(R.id.adView); //this will give null
AdView adView = findViewById(R.id.adsLayout);  //this will be AdView

If you do not give id to include element then it is ok to use view id. Also if your view is inside any ViewGroup like FrameLayout then it is ok to use view id.
