Activity에서 Fragment로 값 넘기기

Activity

getSupportFragmentManager().beginTransaction().add(R.id.container, fragment1).commit();
//번들객체 생성, text값 저장
Bundle bundle = new Bundle(); 
bundle.putString("type",type);
//fragment1로 번들 전달
fragment1.setArguments(bundle);

Fragment

@Override
public  void  onCreate ( Bundle  savedInstanceState ) {
     	super . onCreate (savedInstanceState);
        //RequestActivity에서 전달한 번들 저장
        try {
            Bundle bundle = getArguments();
            if(bundle != null) {
                type = bundle.getString("type");
            }
        } catch(Exception e) {
            Log.d("오류",String.valueOf(e));
        }
    }
