    In addflipperimages(ViewFlipper flipper) method you are adding bunch of images to ViewFlipper for that you are creating imageview, set tag to imageview, set imageview clickable true then write onclick method to imageview. go through the fallowing code it may works for you
    here ids[] is an array of image ids

    private void addFlipperImages(ViewFlipper flipper) {
    
            int imageCount = ids.length;
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.FILL_PARENT,
                RelativeLayout.LayoutParams.FILL_PARENT);
    
        for (int count = 0; count <imageCount; count++) {
            ImageView imageView = new ImageView(this);
            Bitmap imbm = BitmapFactory.decodeResource(this.getResources(),ids[count]);          
            imageView.setImageBitmap(imbm);
    
            imageView.setLayoutParams(params);
            imageView.setTag(count);
            imageView.setClickable(true);
    
            imageView.setOnClickListener(new OnClickListener() {
    
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    int id=(Integer) v.getTag();
                    Toast.makeText(ImageSliderVertical.this, id+"", Toast.LENGTH_LONG).show();
    
                }
            });
            flipper.addView(imageView);
            flipper.setTag(count);
    
                      }
    
    }

    I used this flipper.indexOfChild(flipper.getCurrentView())

    Make use of indexOfChild().

    Check this Post

    How can I programmatically display a ViewFlipper's second child?

    May this works for you.

    Use this to get the current Child position:

    flipper.getDisplayedChild();
    

    And this to set child number to view:

    flipper.setDisplayedChild(8);
