It is simple as passing a 0 as the resource

show_image.SetImageResource(0);

Agree with Pranav, but i think you can also access inbuild resources of Android itself.

Try:

imgView.setImageResource(android.R.color.transparent);

       show_image.setImageBitmap(null);

You need to check the length of the url . If it is 0 then you have to set null to imageviwe.

Please try this.

if(imageneel.get(i).length() == 0)
{            
    show_image.setImageBitmap(null);
}
