How to make 'if button clicked, do this' in Android Studio?

Question

I am new to Android Studio. I am working on a ArCore sample project. I want to add a button, when clicked the plane finding mode will be vertical otherwise horizontal. Before voting negative, I have gone through these posts: How can I write “if button clicked” in an If statement in android studio?

Checking if a button has been clicked

The following is the snippet of my code:

if(y > 0){
            Config config = new Config(session);
            
            
            //config.setPlaneFindingMode(Config.PlaneFindingMode.VERTICAL); If button clicked, this
            config.setPlaneFindingMode(Config.PlaneFindingMode.HORIZONTAL); //otherwise this
            session.configure(config);
            Globals.notRecording = true;


        }

Answer 1

button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
              // Perform action on click   

            }
          });

Just use this code in OnClickListener . when you tap button call this

config.setPlaneFindingMode(Config.PlaneFindingMode.VERTICAL);
