android - 如何将包含 url 的数组传递给图像源到 GridView 的图像适配器？

Question

如何将包含 url 的数组作为图像源传递给 GridView 的图像适配器？我有一个工作图像适配器。但问题是适配器的 getView 方法只返回一个 ImageView 。有人能告诉我如何将包含 url 的数组传递给 gridview 的图像适配器吗？ getview 方法在这里

    public View getView(final int position, View convertView, ViewGroup parent) {
    ImageView imageView = null;

        if (convertView == null) {  // if it's not recycled, initialise some attributes
            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;
        }

    //  Bitmap bmp  = loadBitmap(url[i]);
        Bitmap bmp  = loadBitmap("http://www.fgj.com/aero/planes/boeing/boeingf15.jpg");
        System.out.println("in adapter :" + url[i]);
        imageView.setImageBitmap(bmp);

    //imageView.setImageResource(mThumbIds[position]);
    //Bitmap bmp  = loadBitmap("http://www.fgj.com/aero/planes/boeing/boeingf15.jpg");
    return imageView;
}

ArrayList<String> list;//list of image paths
public View getView(int position, View convertView, ViewGroup parent) 
{
    ImageView imageView;
    if (convertView == null) {
        imageView = new ImageView(context);
        imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setPadding(5, 5, 5, 5);
    } else {
        imageView = (ImageView) convertView;
    }
    Bitmap myBitmap = BitmapFactory.decodeFile("/sdcard/foldername/"+list.get(position));
    imageView.setImageBitmap(myBitmap);
    imageView.setBackgroundColor(-1);
    return imageView;
}
