Glide 图片尺寸问题

//获取图片显示在ImageView后的宽高
Glide.with(this)
    .load(imgUrl)
    .asBitmap()//强制Glide返回一个Bitmap对象
    .listener(new RequestListener<String, Bitmap>() {
        @Override
        public boolean onException(Exception e, String model, Target<Bitmap> target, boolean isFirstResource) {
            Log.d(TAG, "onException " + e.toString());
            return false;
        }

        @Override
        public boolean onResourceReady(Bitmap bitmap, String model, Target<Bitmap> target, boolean isFromMemoryCache, boolean isFirstResource) {
            int width = bitmap.getWidth();
            int height = bitmap.getHeight();
            Log.d(TAG, "width2 " + width); //400px
            Log.d(TAG, "height2 " + height); //400px
            return false;
        }
    }).into(mIv_img);

//获取图片真正的宽高
Glide.with(this)
    .load(imgUrl)
    .asBitmap()//强制Glide返回一个Bitmap对象
    .into(new SimpleTarget<Bitmap>() {
        @Override
        public void onResourceReady(Bitmap bitmap, GlideAnimation<? super Bitmap> glideAnimation) {
            int width = bitmap.getWidth();
            int height = bitmap.getHeight();
            Log.d(TAG, "width " + width); //200px
            Log.d(TAG, "height " + height); //200px
        }
    });
