전역 변수에

var fragmentTransaction = fragmentManager.beginTransaction()

선언을 하고

commit()을 한 후에 다시 transaction을 생성해줘야 한다고 한다.

example

 fragmentTransaction.add(R.id.frame_container, fragmentCustomers).commit()
        fragmentTransaction = fragmentManager.beginTransaction()
        fragmentTransaction.add(R.id.frame_container, fragmentHome).commit()
        fragmentTransaction = fragmentManager.beginTransaction()
        fragmentTransaction.add(R.id.frame_container, fragmentMemo).commit()

아니면 전역변수 생성없이

 supportFragmentManager.beginTransaction().add(R.id.frame_container, fragmentCustomers).commit()
        supportFragmentManager.beginTransaction().add(R.id.frame_container, fragmentMemo).commit()
        supportFragmentManager.beginTransaction().add(R.id.frame_container, fragmentHome).commit()
