Android Kotlin-Glide onLoadFailed尝试另一个错误的图像url

Question

我已经搜索了一个解决方案，但我只找到了100000个关于如何使用占位符的问题，这不是我所需要的。

如果第一个url失败，我需要Glide尝试从另一个url加载图像。

这就是我尝试过的：

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)

它适用于我的测试设备，即android 8和11。

但一些用户正在崩溃，包括api 8和11。

这就是错误：

如何正确执行此操作？

Answer 1

您可以在没有Handler的情况下完成此操作。

只使用这个tryAlternative()而不是

Handler(Looper.getMainLooper()).postDelayed({
tryAlternative()
}, 500)
