    for(int i=0;i<images.length;i++){
    final ImageView imageView = (ImageView) getImageView(images[i]);
    imageView.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        Intent i=new Intent(getActivity(),book.class);
        int id=imageView.getId();
        i.putExtra("id",id);
        startActivity(i);
    }
   });
   }
 ////
    return view;
}
private void addImagesToThegallery() {

    for (Integer image : images) {
        imageGallery.addView(getImageView(image));
        imageGallery2.addView(getImageView(image));
    }
}


private View getImageView(Integer image) {
    ImageView imageView = new  
  ImageView(getActivity().getApplicationContext());
    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(260, 400);
    lp.setMargins(0, 0, 10, 0);

    imageView.setLayoutParams(lp);
    imageView.setImageResource(image);
    imageView.setScaleType(ImageView.ScaleType.FIT_XY);
    return imageView;

You can also set the OnClickListener on your getImageView Method

EDIT: add a TAG on your imageView with the ImageResource, then recover the TAG on the image OnClick Method, Like This:

private View getImageView(Integer image, Integer index) {
    ImageView imageView = new
            ImageView(this.getApplicationContext());
    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(260, 400);
    lp.setMargins(0, 0, 10, 0);

    imageView.setLayoutParams(lp);
    imageView.setImageResource(image);
    //Create a TAG on your Strings Resources
    //"IMAGE_TAG" with any value
    imageView.setTag(R.string.IMAGE_TAG, image);
    imageView.setScaleType(ImageView.ScaleType.FIT_XY);
    imageView.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            int image = (int)v.getTag(R.string.IMAGE_TAG);
            switch (image)
            {
                case R.drawable.mba:
                {
                    //action for your image
                } break;
                //and so on..

            }
        }
    });

    return imageView;
}

You'll want to call setOnClickListener on the ImageView for each image.

You could do this in your getImageView method and have different behaviour depending on which image index you've passed to the method, or you could call the following from your for loop. 

ImageView imageView = (ImageView) getImageView(i); 
imageView.setOnClickListener(new View.OnClickListener() {
     public void onClick(View v) {
         // Perform action on click
     }
 });

Try adding this inner class inside your Activity/Fragment

class ImageClickListener implements View.OnClickListener {

public void onClick(View v) {
    switch(v.getId()) {
        case images[0]:
            // handle click for first image
        break;
            //And so on and so forth
    }


}

Then simply set the click listener inside the loop for each ImageView

for (Integer image : images) {
    ImageView image1 = getImageView(image);
    ImageView image2 = getImageView(image);
    image1.setOnClickListener(new ImageClickListener());
    image2.setOnClickListener(new ImageClickListener());
    imageGallery.addView(image1);
    imageGallery2.addView(image2);
}

You can either set the onClick listener for each view inside the for loop or simply use the view.getId method inside the listener you already created and act accordingly.
