import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import com.example.beans.SongInfo;

public class LazyAdapter extends BaseAdapter {

    private Activity activity;
    private ArrayList data1;
    private static LayoutInflater inflater=null;
    //public ImageLoader imageLoader; 

    public LazyAdapter(Activity a, ArrayList d) {
        activity = a;
        data1=d;
        inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
      //  imageLoader=new ImageLoader(activity.getApplicationContext());
    }

    public int getCount() {
        return data1.size();
    }

    public Object getItem(int position) {
        return position;
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        View vi=convertView;
        if(convertView==null)
            vi = inflater.inflate(R.layout.list_row, null);

        TextView title = (TextView)vi.findViewById(R.id.title); // title
        TextView artist = (TextView)vi.findViewById(R.id.artist); // artist name
        TextView duration = (TextView)vi.findViewById(R.id.duration); // duration
        ImageView thumb_image=(ImageView)vi.findViewById(R.id.list_image); // thumb image

        SongInfo song=data1.get(position);

        // Setting all values in listview
        title.setText(song.getTitle());
        artist.setText(song.getArtist());
        duration.setText(song.getDuration());
        if(song.getArtist().equalsIgnoreCase("Adele")){
            thumb_image.setImageResource(R.drawable.rihanna);

        }else if(song.getArtist().equalsIgnoreCase("Rihanna")){
            thumb_image.setImageResource(R.drawable.rihanna);
        }else if(song.getArtist().equalsIgnoreCase("Eminem")){

        }else if(song.getArtist().equalsIgnoreCase("Michael Jackson")){
            thumb_image.setImageResource(R.drawable.rihanna);
        }


//        imageLoader.DisplayImage(song.get(CustomizedListView.KEY_THUMB_URL), thumb_image);
        return vi;
    }
