TextView加载Html文本显示图片问题

最优实现方案，异步加载图片本人使用ImageLoader，各位也可以使用其他工具加载获得Bitmap类型图片
图片超出view显示宽度时缩放到view显示宽度，否则显示图片在手机中的实际大小

代码——使用kotlin编写

skuDetailsIntroTv.movementMethod = LinkMovementMethod.getInstance()  //设置连接可点击跳转
skuDetailsIntroTv.text = Html.fromHtml(sku.getViewProdIntro(), Html.ImageGetter { source ->
    val drawable = LevelListDrawable()
    ImageLoader.getInstance().loadImage(source, object : ImageLoadingListener {
        override fun onLoadingComplete(imageUri: String?, view: View?, result: Bitmap?) {
            if (result != null) {
                val bitmapDrawable = BitmapDrawable(resources, result)
                //添加一层bitmap
                drawable.addLevel(1, 1, bitmapDrawable)

                //根据手机像素密度重新计算
                val scale = resources.displayMetrics.density
                val bitmapWidth = Math.round(result.width * scale)
                val bitmapHeight = Math.round(result.height * scale)

                //防止图片超出view显示区域宽度
                val viewContentWidth = skuDetailsIntroTv.width - skuDetailsIntroTv.paddingLeft -
                        skuDetailsIntroTv.paddingRight
                val width = if (viewContentWidth < bitmapWidth) viewContentWidth else bitmapWidth
                //等比例缩放
                val height = bitmapHeight * width / bitmapWidth
                drawable.setBounds(0, 0, width, height)
                drawable.level = 1

                //异步加载的drawable需要重新加载，invalidate()无效果，暂时的解决方案
                val text = skuDetailsIntroTv.text
                skuDetailsIntroTv.text = text
                skuDetailsIntroTv.refreshDrawableState()
            }
        }

        override fun onLoadingStarted(imageUri: String?, view: View?) {
        }

        override fun onLoadingCancelled(imageUri: String?, view: View?) {
        }

        override fun onLoadingFailed(imageUri: String?, view: View?, failReason: FailReason?) {
        }
    })
    drawable
}, null)
