2.5 监听图片资源加载结果

2.5.1 Drawable

   Glide.with(this).load(url).transform(CircleCrop())
            .listener(object : RequestListener<Drawable> {
                override fun onLoadFailed(
                    e: GlideException?,
                    model: Any?,
                    target: Target<Drawable>,
                    isFirstResource: Boolean
                ): Boolean {
                    Log.d("MainActivity", "onLoadFailed")
                    return false
                }

                override fun onResourceReady(
                    resource: Drawable,
                    model: Any,
                    target: Target<Drawable>?,
                    dataSource: DataSource,
                    isFirstResource: Boolean
                ): Boolean {
                    Log.d("MainActivity", "onResourceReady")
                    return false
                }
            }).into(imgCover)

2.5.2 Bitmap

Glide.with(this).asBitmap().load(url).transform(CircleCrop())
            .listener(object : RequestListener<Bitmap> {
                override fun onLoadFailed(
                    e: GlideException?,
                    model: Any?,
                    target: Target<Bitmap>,
                    isFirstResource: Boolean
                ): Boolean {
                    Log.d("MainActivity", "onLoadFailed")
                    return false
                }

                override fun onResourceReady(
                    resource: Bitmap,
                    model: Any,
                    target: Target<Bitmap>?,
                    dataSource: DataSource,
                    isFirstResource: Boolean
                ): Boolean {
                    Log.d("MainActivity", "onResourceReady")
                    return false
                }
            }).into(imgCover)
