Glide 加载图片 到动态ImageView

Glide.with(mContext)
    .asBitmap()
    .load(imageUrl)
    .apply(options)
    //.into(mImageView);
    .into(mTarget);

下面在获取到下载图片尺寸信息后，在给imageview 设置图片资源，

private SimpleTarget mTarget = new SimpleTarget<Bitmap>() {
    @Override
    public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {
        int imageWidth = resource.getWidth();
        int imageHeight = resource.getHeight();
        int layoutWidth = mImageLayoutWidth;
        int layoutHeight = mRecyclerView.getLayoutParams().height;
        float imageRatio = (float) imageWidth / imageHeight;
        float layoutRatio = (float) layoutWidth / layoutHeight;
        int imageViewHeight = 0;
        int imageViewWidth = 0;
        if (imageRatio > layoutRatio) {
            imageViewWidth = layoutWidth;
            imageViewHeight = (int) ((float) layoutWidth / imageRatio);
        } else {
            imageViewHeight = mRecyclerView.getLayoutParams().height;
            imageViewWidth = (int) (imageRatio * imageViewHeight);
        }
        LogUtil.i(TAG + " mTarget.onResourceReady() imageWidth:" + imageWidth + " imageHeight:"
            + imageHeight + " imageViewWidth:" + imageViewWidth + " imageViewHeight:" + imageViewHeight
            + " layoutWidth:" + layoutWidth + " layoutHeight:" + layoutHeight);
        ViewGroup.LayoutParams para = mImageView.getLayoutParams();
        para.height = imageViewHeight;
        para.width = imageViewWidth;

        mImageView.setImageBitmap(resource);
    }
};
