Android Kotlin - Glide onLoadFailed 在出错时尝试另一个图片网址

Question 1

我一直在寻找解决方案，但我找到的都是关于如何使用占位符的100000个问题，这并不是我需要的。

我需要Glide尝试从另一个URL加载图片，如果第一个URL失败的话。

这是我所尝试的。

        fun tryAlternative(){
            val alternativeUrl = func.getMediaUrl(mediaServer) + mediaParameters
            Glide
                .with(context)
                .load(alternativeUrl)
                .listener(object : RequestListener<Drawable> {
                    override fun onLoadFailed(
                        e: GlideException?,
                        model: Any?,
                        target: Target<Drawable>?,
                        isFirstResource: Boolean
                    ): Boolean {
                        return false
                    override fun onResourceReady(
                        resource: Drawable?,
                        model: Any?,
                        target: Target<Drawable>?,
                        dataSource: DataSource?,
                        isFirstResource: Boolean
                    ): Boolean {
                        holder.picLoadIcon.visibility = View.GONE
                        holder.image.requestLayout()
                        holder.picContainer.layoutParams.height = ViewGroup.LayoutParams.WRAP_CONTENT
                        holder.picContainer.requestLayout()
                        return false
                .apply(glideOptions)
                .fitCenter()
                // .transform(CutOffLogo())
                .into(holder.image)
        Glide
            .with(context)
            .load(fileUrl)
            .listener(object : RequestListener<Drawable> {
                override fun onLoadFailed(
                    e: GlideException?,
                    model: Any?,
                    target: Target<Drawable>?,
                    isFirstResource: Boolean
                ): Boolean {
                    Handler(Looper.getMainLooper()).postDelayed({
                        tryAlternative()
                    }, 500)
                    return false
                override fun onResourceReady(
                    resource: Drawable?,
                    model: Any?,
                    target: Target<Drawable>?,
                    dataSource: DataSource?,
                    isFirstResource: Boolean
                ): Boolean {
                    holder.picLoadIcon.visibility = View.GONE
                    holder.image.requestLayout()
                    holder.picContainer.layoutParams.height = ViewGroup.LayoutParams.WRAP_CONTENT
                    holder.picContainer.requestLayout()
                    return false
            .apply(glideOptions)
            .fitCenter()
            // .transform(CutOffLogo())
            .into(holder.image)
它在我的测试设备上工作，这些设备是安卓8和11。
但有些用户得到了崩溃，包括api8和11。
This is the error:

How to do this correctly?

Question 2


          
           
            你可以在没有处理程序的情况下做到这一点。
