强转字符串类型+截取字符串

               //将double类型,强转成String类型

                double price = list.get(i).getPrice();

                String b=String.valueOf(price);
                holder.te2.setText(b);

                String images = list.get(i).getImages();
                String a = images;
                String[] aa = a.split("\|");  //以每个|作为分割点,得到的是数组aa
                for (int j = 0 ; j<aa.length;j++){
                    Toast.makeText(MainActivity.this,aa[j],Toast.LENGTH_SHORT).show();
                }

                ImageLoader instance1 = ImageLoader.getInstance();

               //aa[0]:指的是获得第一个字符串,  aa[1]:指的是获得第二个字符串

               instance1.displayImage(aa[0],holder.img1);
