                R.drawable.c3,
                R.drawable.c4,
                R.drawable.c5,
                R.drawable.c6,
                R.drawable.c7,
                R.drawable.c8
        };
     @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            // Note that Gallery view is deprecated in Android 4.1---
            Gallery gallery = (Gallery) findViewById(R.id.gallery1);
            //Adapter list
            gallery.setAdapter(new ImageAdapter(this));
            gallery.setOnItemClickListener(new OnItemClickListener() {
            //onclick event              
  public void onItemClick(AdapterView<?> parent, View v, int position,long id)
                {//displaying image clicked i am trying to invisible this pic when click
                    Toast.makeText(getBaseContext(),"pic" + (position + 1) + " selected",//dispplpaying msg
                            Toast.LENGTH_SHORT).show();
                    //imageIDs[position].setVisible(false);
                    // display the images selected
                    ImageView imageView = (ImageView) findViewById(R.id.image1);
                    imageView.setImageResource(imageIDs[position]);
                    //setting image on screen from using xml 
                }
            });
        }
        public class ImageAdapter extends BaseAdapter {
            private Context context;
            private int itemBackground;
            public ImageAdapter(Context c)
            {
                context = c;
                // sets a grey background; wraps around the images
                TypedArray a =obtainStyledAttributes(R.styleable.MyGallery);
                itemBackground = a.getResourceId(R.styleable.MyGallery_android_galleryItemBackground, 0);
                a.recycle();
            }
            // returns the number of images
            public int getCount() {
                return imageIDs.length;
            }
            // returns the ID of an item
            public Object getItem(int position) {
                return position;
            }
            // returns the ID of an item
            public long getItemId(int position) {
                return position;
            }
            // returns an ImageView view
            public View getView(int position, View convertView, ViewGroup parent) {
                ImageView imageView = new ImageView(context);
                //imageIDs[position].setVisible(false);
                //i am trying it here but its not working
                imageView.setImageResource(imageIDs[position]);
                imageView.setLayoutParams(new Gallery.LayoutParams(100, 100));
                imageView.setBackgroundResource(itemBackground);
                return imageView;
            }
        }
    }

I'm assuming you're trying to use this code:

//imageIDs[position].setVisible(false);

If so then what you're doing is calling setVisible on an Integer, which does not have that method. What you need to do is get a reference to the ImageView in which the image is being displayed and then call setVisibility(View.INVISIBLE) or setVisibility(View.GONE) on it.

Also it seems like you're trying to set the image to invisible but then you go and put the same resource back into the ImageView so I'm not sure what you're trying to do there.
