this model_ProductMaster.listProductImages.size()is images list:
这个model_ProductMaster.listProductImages.size()是图像列表：
private void setProductImageInView() {
LayoutInflater layoutInflater = (LayoutInflater) viewFullImage
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
linear_below_img_view.removeAllViews();
// Set the image height,widt,scaling and margin of the imageview
for (int i = 0; i < model_ProductMaster.listProductImages.size(); i++) {
convertView = layoutInflater.inflate(

final ImageView img = (ImageView) convertView
.findViewById(R.id.xml_full_img_below_middleimg);
img.setMinimumWidth((int) viewFullImage.getResources()

img.setMaxHeight((int) viewFullImage.getResources().getDimension(

img.setScaleType(ScaleType.CENTER_INSIDE);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(

layoutParams.setMargins(10, 0, 0, 0);
layoutParams.gravity = Gravity.CENTER;
convertView.setLayoutParams(layoutParams);
img.setScaleType(ScaleType.FIT_XY);
imageLoader.displayImage(
model_ProductMaster.listProductImages.get(i).ImageUrl, img,
options, animateFirstListener);
linear_below_img_view.addView(convertView);
convertView.setId(i);
convertView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
