안드로이드 인텐트 값넘기기

Question

<MainActivity.java>

public class MainActivity extends AppCompatActivity {
    ArrayList<Song> al = new ArrayList<Song>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        al.add(new Song("소녀",R.drawable.img01,"오혁(Hyukk Oh)"));
        al.add(new Song("Prologue",R.drawable.img02,"허각"));
        al.add(new Song("못먹는 감 (Sour Grapes)",R.drawable.img03,"산이(San E)"));
        al.add(new Song("걱정말아요 그대",R.drawable.img04,"이적"));
        al.add(new Song("그날을 내 등 뒤로",R.drawable.img05,"허각"));
        al.add(new Song("청춘 (feat. 김창완)",R.drawable.img06,"김필(Kim Feel"));
        al.add(new Song("Hot Pink",R.drawable.img07,"EXID(이엑스아이디)"));
        al.add(new Song("널 생각해",R.drawable.img08,"윤하(Younha/ユンナ)"));
        al.add(new Song("사랑은 가슴이 시킨다 Part.3",R.drawable.img09,"버즈(Buzz)"));
        al.add(new Song("또 다시 사랑",R.drawable.img10,"임창정"));


        MyAdapter adapter = new MyAdapter(
                getApplicationContext(),
                R.layout.activity_row,
                al);

        ListView lv = (ListView)findViewById(R.id.listView1);
        lv.setAdapter(adapter);

        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {

                Intent intent = new Intent(
                        getApplicationContext(),
                        (Class<?>) songdetail.Class);


                intent.putExtra("title", al.get(position).title);
                intent.putExtra("artist", al.get(position).artist);
                intent.putExtra("img", al.get(position).img);

                startActivity(intent);
            }
        });
    }
}

class MyAdapter extends BaseAdapter {
    Context context;
    int layout;
    ArrayList<Song> al;
    LayoutInflater inf;
    public MyAdapter(Context context, int layout, ArrayList<Song> al) {
        this.context = context;
        this.layout = layout;
        this.al = al;
        inf = (LayoutInflater)context.getSystemService
                (Context.LAYOUT_INFLATER_SERVICE);
    }
    @Override
    public int getCount() {
        return al.size();
    }
    @Override
    public Object getItem(int position) {
        return al.get(position);
    }
    @Override
    public long getItemId(int position) {
        return position;
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView==null) {
            convertView = inf.inflate(layout, null);
        }
        ImageView iv = (ImageView)convertView.findViewById(R.id.imageView1);
        TextView tvName = (TextView)convertView.findViewById(R.id.textView1);
        TextView tvInfo = (TextView)convertView.findViewById(R.id.textView2);

        Song m = al.get(position);
        iv.setImageResource(m.img);
        tvName.setText(m.title);
        tvInfo.setText(m.artist);

        return convertView;
    }
}

class Song {
    String title = "";
    int img;
    String artist = "";
    public Song(String title, int img, String artist) {
        super();
        this.title = title;
        this.img = img;
        this.artist = artist;
    }
    public Song() {}
}

<songdetail.java>


public class songdetail extends Activity {

    public static Object Class;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_songdetail);

        TextView tvTitle = (TextView)findViewById(R.id.textView1);
        TextView tvArtist = (TextView)findViewById(R.id.textView2);
        ImageView iv = (ImageView)findViewById(R.id.imageView1);

        Intent intent = getIntent();
        tvTitle.setText(intent.getStringExtra("title"));
        tvArtist.setText(intent.getStringExtra("artist"));
        iv.setImageResource(intent.getIntExtra("img", 0));

    }

    public class Class {
    }
}

인텐트값넘기기인데 앱은 실행되지만 곡 목록을 선택하면 프로그램이 종류되네요 ㅠ

Comments

intent.getIntExtra("img", 0) 값이 없는 리소스를 반환하지 않았거나, AndroidManifset.xml에 songdetail activity를 동록 하지 않는 이상,
딱히 문제를 찾기 어렵네요..  로그캣을 올려주세요.

Intent에 getApplicationContext()말고 MainActivity.this로 넘겨보는건 어떤가요?
