传递ImageView数组到bitmap

如题，如何传递？

ImageView数组：

private Integer[] Imgid = {
            R.drawable.pic1,
            R.drawable.pic2,
            R.drawable.pic3,
            R.drawable.pic4,
    };

    Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(),**R.drawable.pic1[]???**);

ImageView ImageView = (ImageView)findViewById(Imgid[index]);

这样不行吗

        Integer[] Imgid = {
                R.drawable.share,
                R.drawable.share,
                R.drawable.share,
                R.drawable.share,
        };

        Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(),Imgid[0],null);//根据下标取
