            {
                public void onClick(View v)
                {
                    final Animation out= AnimationUtils.loadAnimation(this, android.R.anim.slide_out_left);
                    final Animation in= AnimationUtils.loadAnimation(this, android.R.anim.slide_in_right);
                    imageSwitcher.setFactory(this);
                    imageSwitcher.setInAnimation(in);
                    imageSwitcher.setOutAnimation(out);
                    imageSwitcher.setImageResource(imageIDs[0]);

                }

            });
        }
public View makeView()
    {
        ImageView imageView = new ImageView(this);
        imageView.setBackgroundColor(0xFF000000);
                imageView.setScaleType(ImageView.ScaleType.CENTER);
        imageView.setLayoutParams(new ImageSwitcher.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
        return imageView;
    }       

}

loadAnimation of previous button i got The method loadAnimation(Context, int) in the type AnimationUtils is not applicable for the arguments (new View.OnClickListener(){}, int) — sunny, Jun 20 '11 at 12:29
Also in "slide_out_left" and "slide_in_right" red underline is coming saying "slide_in_right/slide_out_left cannot be resolved or is not a field" — sunny, Jun 20 '11 at 12:33

Your problem is that when you refer to this in your OnClickListener your are referring to that particular listener and not to your current Activity. You should change it to

 final Animation out= AnimationUtils.loadAnimation(image_slider.this, android.R.anim.slide_out_right); 
 final Animation in= AnimationUtils.loadAnimation(image_slider.this, android.R.anim.slide_in_left);
 ...
 imageSwitcher.setFactory(image_slider.this);

And use android.R.anim.slide_in_left and android.R.anim.slide_out_right not slide_out_left and "slide_in_right" because these don't exist.

BTW, good Java practice is to start your class name with a capital letter, e.g. ImageSlider
