  String[] descs;
  HashMap<String, String> map = new HashMap<String, String>();

  public Appetizerlist(Context context, JSONArray imageArrayJson) {
      Context=context;
    //inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    //  imageLoader=new ImageLoader(activity);
    inflater=LayoutInflater.from(context);
    this.mImages = new ImageView[imageArrayJson.length()];
    this.bmps = new Bitmap[imageArrayJson.length()];
    this.itemnames = new String[imageArrayJson.length()];
    this.prices=new String[imageArrayJson.length()];
    this.descs=new String[imageArrayJson.length()];
    try {

      for (int i = 0; i < imageArrayJson.length(); i++) {
        JSONObject image = imageArrayJson.getJSONObject(i);
        qrimage = image.getString("itemimage");
        itemname = image.getString("itemname");
        price=image.getString("price");

        itemnames[i] = itemname;
        prices[i]=price;
       descs[i]=desc;


        byte[] qrimageBytes = Base64.decode(qrimage.getBytes());

        bmp = BitmapFactory.decodeByteArray(qrimageBytes, 0,
                                            qrimageBytes.length);
        int width = 100;
        int height = 100;
        resizedbitmap = Bitmap.createScaledBitmap(bmp, width, height,
                                                  true);
        bmps[i] = bmp;

        mImages[i] = new ImageView(context);
        mImages[i].setImageBitmap(resizedbitmap);

        mImages[i].setScaleType(ImageView.ScaleType.FIT_START);


        // tv[i].setText(itemname);
      }
      System.out.println(map);

    } catch (Exception e) {

              view = inflater.inflate(R.layout.appetiserlistview, null);
            viewHolder = new ViewHolder();
            viewHolder.image=(ImageView)view.findViewById(R.id.appetiserimage);
            viewHolder.text = (TextView) view.findViewById(R.id.appetisertext);
            viewHolder.desc=(TextView)view.findViewById(R.id.appetiserdesc);
            viewHolder.price=(TextView)view.findViewById(R.id.appetiserdesc);
            viewHolder.checkbox = (CheckBox) view.findViewById(R.id.bcheck);

    protected TextView text,price,desc;
    protected ImageView image;
    protected CheckBox checkbox;

Answer 1

you can use OnItemClickListener() to pass this image String qrimage = image.getString("itemimage"); to your new Activity using intent.putExtra("qrimage",qrimage); and Decode this string in your New Activity as you have done this in your ListView.

If there is an array of images use ArrayList to store every image and pass the arrayList to intent using intent.putStringArrayListExtra("arrImages", bmps); and get it in another Activity using

Intent i = getIntent();  
arrImages = i.getStringArrayListExtra("arrImages");

Hope it Helps.
