Answer 1

It seems that you can set the layout's width as the image's real size. or compute a scale factor by some logic. such as you can decrease the image's width when the image is far away the gallery center.

public View getView(int position, View convertView, ViewGroup parent) { ImageView i = new ImageView(this.myContext);

        i.setImageResource(this.myImageIds[position]);
        /* Image should be scaled as width/height are set. */
        i.setScaleType(ImageView.ScaleType.FIT_XY);
        /* Set the Width/Height of the ImageView. */
        int selectedPosition = ((Gallery) parent).getSelectedItemPosition();

        float scale = getScale(position - selected);

            int width = Math.round(IMAGE_WIDTH * scale);

            int height = Math.round(IMAGE_HEIGHT * scale);

            i.setLayoutParams(new Gallery.LayoutParams(width, height));

        return i;
    }

In your layout xml file be sure to set android:layout_width="fill_parent", like this

<Gallery 
            android:id="@+id/gallery"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="2dip"
                        android:layout_gravity="center_horizontal|bottom"
                        android:padding="1dip"
                        android:background="#AA000000"
            />
