I had the same problem and I had no reference at all to "wrap_content" in the layouts attirbute. Although this is an old thread I couldn't figured it out how to solve the issue. Thus, I mitigated it by adding a List in the Adapter that holds the positions already drawn, as shown in the code below. I think that it is not the right away of doing that, but it worked for me.

public class ImageAdapter extends BaseAdapter {
    private Context mContext;
    private List usedPositions  = new ArrayList();

    public ImageAdapter(Context c, List imageUrls) {
        mContext = c;
        ...
    }

    ...

    // create a new ImageView for each item referenced by the Adapter
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView;
        if (convertView == null) { 
            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(8, 8, 8, 8);
        } else {
            imageView = (ImageView) convertView;
        }

        if (!usedPositions.contains(position)) {
            // Your code to fill the imageView object content
            usedPositions.add(position); // holds the used position
        }

        return imageView;
    }
}
