Question

我正在从动态来源加载图片并将其加载到我的应用中。但是有时候我的应用程序中的图像太小而且看起来很糟糕。我想要做的是获取图像大小，如果小于5x5，则根本不显示ImageView。

如何实现这一目标？

当我使用sizeReadyCallback时，它返回ImageView的大小而不是image。当我使用请求监听器时，它返回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);
        }
    });

@TWiStErRob在评论中提供了更好的解决方案： better solution

对于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);
         }
     });

重点是在设置为ImageView之前获取位图。

这个问题很旧，但是我偶然发现了类似的情况，我需要检查原始图像的大小。经过一番挖掘之后，我在Github上找到了this线程，它具有解决方案。

我将复制pandasys编写的最新版本（glide v4）solution。

这段代码是Kotlin，但是Java专家应该不会遇到麻烦。进行加载的代码如下所示：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<form name=f1 method=post>
    	  <div class="parentDiv">
    		  <input type="checkbox" class='chkbox' name=others>Others
              <input type=text name=other_text class='txtbox' disabled='disabled'>
    	  </div>

          <div class="parentDiv">
        		  <input type="checkbox" class='chkbox' name=others>Others
                  <input type=text name=other_text class='txtbox' disabled='disabled'>
          </div>
          
          <div class="parentDiv">
        		  <input type="checkbox" class='chkbox' name=others>Others
                  <input type=text name=other_text class='txtbox' disabled='disabled'>
          </div>
</form>

可重用的选项是：

Glide.with(activity)
 .`as`(Size2::class.java)
 .apply(sizeOptions)
 .load(uri)
 .into(object : SimpleTarget<Size2>() {
   override fun onResourceReady(size: Size2, glideAnimation: Transition<in Size2>) {
     imageToSizeMap.put(image, size)
     holder.albumArtDescription.text = size.toString()
   }

   override fun onLoadFailed(errorDrawable: Drawable?) {
     imageToSizeMap.put(image, Size2(-1, -1))
     holder.albumArtDescription.setText(R.string.Unknown)
   }
 })

我的尺码班大约是：

private val sizeOptions by lazy {
RequestOptions()
    .skipMemoryCache(true)
    .diskCacheStrategy(DiskCacheStrategy.DATA)}

这是我的AppGlideModule的相关部分

data class Size2(val width: Int, val height: Int) : Parcelable {
  companion object {
    @JvmField val CREATOR = createParcel { Size2(it) }
  }

  private constructor(parcelIn: Parcel) : this(parcelIn.readInt(), parcelIn.readInt())

  override fun writeToParcel(dest: Parcel, flags: Int) {
    dest.writeInt(width)
    dest.writeInt(height)
  }

  override fun describeContents() = 0

  override fun toString(): String = "$width x $height"

}

所以回到最初的问题，class BitmapSizeDecoder : ResourceDecoder<File, BitmapFactory.Options> { @Throws(IOException::class) override fun handles(file: File, options: Options): Boolean { return true } override fun decode(file: File, width: Int, height: Int, options: Options): Resource<BitmapFactory.Options>? { val bmOptions: BitmapFactory.Options = BitmapFactory.Options() bmOptions.inJustDecodeBounds = true BitmapFactory.decodeFile(file.absolutePath, bmOptions) return SimpleResource(bmOptions) } }: override fun registerComponents(context: Context, glide: Glide, registry: Registry) { registry.prepend(File::class.java, BitmapFactory.Options::class.java, BitmapSizeDecoder()) registry.register(BitmapFactory.Options::class.java, Size2::class.java, OptionsSizeResourceTranscoder()) class OptionsSizeResourceTranscoder : ResourceTranscoder<BitmapFactory.Options, Size2> { override fun transcode(resource: Resource<BitmapFactory.Options>, options: Options): Resource<Size2> { val bmOptions = resource.get() val size = Size2(bmOptions.outWidth, bmOptions.outHeight) return SimpleResource(size) } }回调您可以检查宽度和高度并决定是否显示图像

     Glide.with(this)
            .asFile()
            .load("your path url image")
            .into(new SimpleTarget<File>() {
                @Override
                public void onResourceReady(@NonNull File resource, @Nullable 
                    Transition<? super File> transition) {
                    fab_raw.setLabelText(""+resource.length());
                }
            });

Answer 4

这个hacky（实际上不是）变体按预期工作。由于此序列中未指定 targetView（.into() 的参数）并且调用了 .preload()，因此图像不会调整到 ImageView 尺寸或额外的 {{1} }}。您将获得原始尺寸的原始图像，然后将其设置为 scaleType 的来源。

ImageView

试试这个：我不确定这个，但你会这样做：

connection string:

Layout code:
    <ImageView
                android:adjustViewBounds="true"
                android:id="@+id/imageView"
                android:scaleType="fitCenter"
                android:src="@android:drawable/ic_menu_camera"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:visibility="visible" />


     Glide.with(context).load(imgpth).placeholder(R.drawable.bg_loading)
                                .error(R.drawable.bg_loading).into(imageProdctBanner).getSize(new SizeReadyCallback() {
                            @Override
                            public void onSizeReady(int width, int height) {
                                Log.e("width","wdthheight "+width+"  :  "+height);
                                //before you load image LOG height and width that u actually got?
                               // mEditDeskLayout.setImageSize(width,height);
                            }
                        });
working perfect its getting image original size.
Happy coding...

在onResource中尝试获取高度和宽度。

 @Override
        public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
            //This returns 0,0
          int width = glideDrawable.getIntrinsicWidth();
    int height = glideDrawable.getIntrinsicHeight();
            return false;
        }

如何在Android上使用Glide获取原始图像大小？
