        @Override
        public View instantiateItem(ViewGroup container, int position) {
                //Context context = container.getContext();
            TouchImageView img = new TouchImageView(container.getContext());
            img.setImageResource(images[position]);
            img.setOnClickListener(new OnClickListener() {

                                @Override
                                public void onClick(View v) {

                               int imagid=images[position];
 System.out.println("Image name " + images[position]);
 bm = BitmapFactory.decodeStream(v.getResources().getDrawable(imagid));// here i need to pass my resId, i can't able to pass

                                }
                        });

            //img.setScaleType(TouchImageView.ScaleType.CENTER_CROP);
            container.addView(img, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
            return img;
        }

        @Override
        public void destroyItem(ViewGroup container, int position, Object object) {
            container.removeView((View) object);
        }

        @Override
        public boolean isViewFromObject(View view, Object object) {
            return view == object;
        }

    }


}

Create another `String[]` with the image names and use that in `onClick` to get the name. — Apoorv, Jun 14 '14 at 06:26

First `img.setTag(position);` Then in `onClick` `int pos=v.getTag();` (maybe you have to cast). Then `fileName=fileNames[pos];` where fileNames is the array Apoorv proposed. — greenapps, Jun 14 '14 at 06:34
Even more simple as you already store the resource id: `int resid=v.getImageResource(). (Think you have to cast. Don't know if function exists). — greenapps, Jun 14 '14 at 06:39
i didn't get image name, getting only the image position as int — Make it Simple, Jun 14 '14 at 06:47

create a String[] which contains file name and set it's itme to img as tag and in onClick get the tag. do something like this

 private static String[] imagesName = {"fiel1","file2",.....};
  .
  .   
 img.setImageResource(images[position]);
 img.setTag(imagesName[position]);      
 img.setOnClickListener(new OnClickListener() {

                           @Override
                            public void onClick(View v) {
                            String filename = v.getTag().toString(); 
 }   
 }

Edit

If you don't want to create String[] then set the images[position] as Tag of img and in onClick get it from tag like getResources().getResourceName((Integer)v.getTag());

This helps me.

Without using `String[]` we can't do it – Make it Simple Jun 14 '14 at 07:22
no man. you should have to assign image name to view, because `images` is Integer array so you can't get name of image. – maddy d Jun 14 '14 at 07:26
can we try like this `container.getResources().getResourceName(position)` but im getting error unable to find resID – Make it Simple Jun 14 '14 at 07:33
you can if you know the `ResourcesID` otherwise no. – maddy d Jun 14 '14 at 07:42

yes its prints like this `packagename:drawable/imagename` if you get like this how you will pass to `BitMap` – Make it Simple Jun 14 '14 at 08:00
need to get image name and pass into `BitMap` – Make it Simple Jun 14 '14 at 08:36
Your very short simple answer does not make clear what you have in mind or problems with. Try to explain better. – greenapps Jun 14 '14 at 08:48
@greenapps i need to get image from from Onclick and pass that image name into bitmap – Make it Simple Jun 14 '14 at 08:55
You are only repeating yourself. We asked for further info. – greenapps Jun 14 '14 at 08:58
@greenapps see my edit in `Onclick` there i need to pass my resId in `BitMap` – Make it Simple Jun 14 '14 at 09:08
Well you already pass a res id. So what is the problem exactly? – greenapps Jun 14 '14 at 09:12
@greenapps yes i got it dude this line is correct i used like this `bm = BitmapFactory.decodeStream(v.getResources(),imagid);` – Make it Simple Jun 14 '14 at 09:16
@maddy comment answer is correct it helps me. i have edited the answer – Make it Simple Jun 14 '14 at 09:20
