如何在Android上使用Glide获得原始图像尺寸? [英] How to get original image size by using Glide on Android?

问题描述

我正在从动态来源加载图像并将其加载到我的应用程序中.但是有时图像太小，在我的应用中看起来很糟糕.我要做的是获取图像大小，如果小于5x5，则根本不显示ImageView.

I am loading images from dynamic sources and loading them in my app. However sometimes the images are so small and looks bad in my app. What I want to do is get image size and if it is smaller than 5x5, don't show the ImageView at all.

如何实现?

当我使用sizeReadyCallback时，它返回ImageView的大小而不是图像.当我使用请求侦听器时，它返回0,0.

When I use sizeReadyCallback, it returns the size of ImageView instead of image. When I use request listener it returns 0,0.

Glide.with(getContext()).load(imageUrl).listener(new RequestListener<String, GlideDrawable>() {
        @Override
        public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
            return false;
        }

        @Override
        public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
            //This returns 0,0
            Log.e("TAG","_width: " + resource.getBounds().width() + " _height:" +resource.getBounds().height());
            return false;
        }
    }).into(ivImage).getSize(new SizeReadyCallback() {
        @Override
        public void onSizeReady(int width, int height) {
            //This returns size of imageview.
            Log.e("TAG","width: " + width + " height: " + height);
        }
    });

对于Glide v4:

For Glide v4:

Glide.with(getContext().getApplicationContext())
     .asBitmap()
     .load(path)
     .into(new SimpleTarget<Bitmap>() {
         @Override
         public void onResourceReady(Bitmap bitmap,
                                     Transition<? super Bitmap> transition) {
             int w = bitmap.getWidth();
             int h = bitmap.getHeight()
             mImageView.setImageBitmap(bitmap);
         }
     });

重点是在将位图设置为 ImageView 之前.

The point is getting the bitmap before set into an ImageView.
