    Method m=new Method;

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)

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

     cc.setImage(R.drawable.album8);
    }
}

My activity Class 2 is

public class activity2 extends AppCompatActivity{


    Method aa=new Method;

      @TargetApi(Build.VERSION_CODES.LOLLIPOP)

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

        ImageView ss= (ImageView) findViewById(R.id.songimage);

User yout "Method" class like this :

public class Method {

    private static Method instance;
    private int image;

    public static synchronized Method getInstance(){
        if(instance == null){
            instance = new Method();
        }

        return instance;
    }

    public int getImage() {
        return image;
    }

    public void setImage(int image) {
        this.image = image;
    }
}

After on your Activitys :

Method.getInstance().getImage();
Method.getInstance().setImage();

Problem with your code : The model instance lost when you open the other activity.

Ps :

That would be a better way, if you pass your image via intent. Link : Using intents to pass data between activities in android

At this point the question is rather vague, could be a few different things.

Could you provide the contents of R.layout.song_list? And at what point are you starting activity2?
