안드로이드 액티비티 전환하기 문의

Question

안녕하세요.

목적:
나라 정보를 클릭하면 액티비티로 전환되어
각 나라의 수도를 알려주려고 합니다.

하지만 버튼이 공통으로 되어있어서 
다른 나라 버튼을 클릭해도 
같은 정보(같은 액티비티)만 나옵니다

지금 코드에서
나라마다 액티비티를 

다르게 줄 수 있는 방법이 있을까요?

아니면, 나라마다 버튼을 

각각 만드는 코드로 수정해야 할까요?

조언좀 해주시기 바랍니다.
감사합니다.

아래는 제 코드입니다.

Answer 1

Intent.putExtra 혹은

bundle에 대해서 검색해 보시면 됩니다.

검색어 : intent bundle

구글까지 안 가시고

네이버에 검색해도 정보를 찾으실수 있습니다.

Answer 2

mlistview.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View v, int position,
                    long id) {
                
                Intent i;
                
                switch (position) {
                case 0 :
                    i = new Intent(getApplicationContext(), Activity1.class);
                    startActivity(i);
                    break;
                case 1 :
                
                    i = new Intent(getApplicationContext(), Activity2.class);
                    startActivity(i);
                    break;
                    
                default:
                    
                    i = new Intent(getApplicationContext(), Activity3.class);
                    startActivity(i);
                    break;
                }
            }
        
        });

 

이런식으로 하면 될것같네요
