Having 2 Possible XML layouts for the same java Class
I am having loads of problems with Banner Ads, namely hiding them if the consumer makes any type of purchase in my App.
These problems can be found here:
setVisibility(View.GONE) causes a Crash
So basically I have a new question.
I have a class MainActivity.java with the associated XML. It is possible to have two options of the XML layout (one with the ad, one without), and through a bit of java code assign one of these two XML layouts to the MainActivity class at runtime?
If so, how can it be done?
Yes, I did thanks. That was one of the answers. Unfortunately it did not work.

There are lots of possible solutions. Here's the simplest one:
Step #1: Create the two layouts — here, I'll call them R.layout.with_ads and R.layout.without_ads
R.layout.with_ads
R.layout.without_ads
Step #2: When you call setContentView() in onCreate() of your activity, pass in either R.layout.with_ads or R.layout.without_ads, based on whatever criteria you wish to use to decide which to use
setContentView()
onCreate()
R.layout.with_ads
R.layout.without_ads
Can you do this if the view was already set in the activity? Or would you have to call
onCreate()?– kfrajer

onCreate()
@kfrajer: You can't call
onCreate(). You can always call setContentView() again, though there are less disruptive solutions.– CommonsWare

onCreate()
setContentView()
@CommonWare I believe the OP is asking to change the view dynamically.

@kfrajer: I do not see that in "It is possible to have two options of the xml layout (one with the ad, one without), and through a bit of java code assign one of these two xml layouts to the MainActivity class at runtime?"

@CommonWare This is the opening of the OP:
having loads of problems with Banner Ads, namely hiding them if the consumer makes any type of purchase in my App. the consumer made a purchase... change the layout, so I understand. Hence, my question. I let the OP answer or clarify if needed.– kfrajer

Yes, you can use conditionals such as if statements or a switch, for instance:
if (your requirement) -> setContentView(layout A)
else -> setContentView(layout B)
Thank for the answer

Did you try view.INVISIBLE (I believe... plz check docs). the problem with GONE is that it removes the View while INVISIBLE hides it. -Kf
