btn = findViewById(R.id.btn);
rb = findViewById(R.id.rb); // make 5 of them
int x=0;

        rb.setOnClickListener(new View.OnClickListener() { // make 5 of them
            @Override
            public void onClick(View v) {
                boolean checked = ((RadioButton) v).isChecked();
                // Check which radiobutton was pressed
                if (checked){
                    x++;
                    }
                }

            }
        });


    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
         System.out.println(x);
        }
      });
