Android ผมอยากทราบวิธีทำหัวข้อของ Listview โดยแบ่งข้อมูลไม่เหมือนกัน

 public class ImageAdapter extends BaseAdapter 
    {	private Holder holder;
        private Context context;
        private ArrayList<HashMap<String, String>> MyArr = new ArrayList<HashMap<String, String>>();

        public ImageAdapter(Context c, ArrayList<HashMap<String, String>> list) 
        {
            context = c;
            MyArr = list;
        }
        
        public int getCount() {
            return MyArr.size();
        }
 
        public Object getItem(int position) {
            return position;
        }
 
        public long getItemId(int position) {
            return position;
        }
		public View getView(int position, View convertView, ViewGroup parent) {
			LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
			
			if (convertView == null) {
				convertView = inflater.inflate(R.layout.activity_column, null); 
			}
			holder = new Holder();
			holder.imageView = (ImageView) convertView.findViewById(R.id.ColImgPath);
			holder.imageView.getLayoutParams().height = 100;
			holder.imageView.getLayoutParams().width = 100;
			holder.imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        	holder.txtPicName = (TextView) convertView.findViewById(R.id.ColImgDesc);
        	holder.day = (TextView) convertView.findViewById(R.id.date);
        	holder.place = (TextView) convertView.findViewById(R.id.place);
        	holder.txtPicName.setTextColor(Color.BLACK);
        	holder.txtPicName.setTypeface(null, Typeface.BOLD);
        	holder.day.setTextColor(Color.RED);
        	holder.place.setTextColor(Color.BLUE);
			holder.txtPicName.setPadding(0, 0, 0, 0);
			holder.txtPicName.setText(MyArr.get(position).get("EXHIBITION_NAME"));
			
			holder.day.setText(MyArr.get(position).get("EXHIBITION_TIME")+" - "+MyArr.get(position).get("EXHIBITION_TIMECLOSE"));
			holder.place.setText(MyArr.get(position).get("DIRECTORY_NAME"));
			return convertView;
		}
		
		private class Holder{
			//public TextView today;
			public TextView txtPicName;
			public TextView day;
			public TextView place;
			public ImageView imageView;
			
		}

if (MyArr.get(position).get("Status") == "Today Exhibition"){
			holder.today.setVisibility(View.VISIBLE);
			holder.today.setText(MyArr.get(position).get("Status"));
			}else if(MyArr.get(position).get("Status") == "Upcoming Exhibition"){
			holder.today.setVisibility(View.VISIBLE);
			holder.today.setText(MyArr.get(position).get("Status"));	
    		}else{
    		holder.today.setVisibility(View.GONE);
    		}
