[Newbie] [Android studio] I put too many image buttons. Is there any other way?

I'm a total beginner.

My level is that I've been following a simple example from the Android studio to the Cotlin for a semester in liberal arts (I don't know the structure of which sentence is why, but I just follow the example sentence...) Understanding the code?Without it, I'm trying to make this and that by organizing what I learned and searching little by little and copying and pasting code if I need anything else.

Recently, in Android Studios, the language is Cotlin, making a simple game There are about 30 spaces on the board where the game horse can move, and each one is made of a button We're rolling the dice to make certain commands of the button go ahead when a horse arrives at a certain compartment. (I made the dice roll simply by showing the image of rolling the dice when I press the button and giving the result.)

I don't know how to use an external link, so I put all the images in the drawer and use them (about 15-20 images) When it gets a bit complicated, the connection between the activities is confusing I was a bit lazy to do it I try to make it work in one activity as much as possible.

For example, turning on the help window doesn't create a separate activity Add containerlayout so that visibility is usually GONE and becomes VISIBLE when you press the button to turn on the help?

But I don't know if it's a lot of work, but it gets really slow and the app keeps turning off...

The reason why I thought of it was

I think... I don't know if it's right.

Please advise if it can be solved by dividing the activity or reducing the button a little bit, or which part should I study and do it in a different way.
