滑翔監聽器不工作

Question

我使用滑翔加載圖像和我添加了一個監聽器知道什麼時候資源是準備好或者是否有任何類型的錯誤：

Glide.with(mContext) 
    .load(url) 
    .placeholder(R.drawable.glide_placeholder) 
    // use dontAnimate and not crossFade to avoid a bug with custom views 
    .dontAnimate() 
    .diskCacheStrategy(DiskCacheStrategy.ALL) 
    .listener(new RequestListener<String, GlideDrawable>() { 
     @Override 
     public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) { 
      // do something 
      return true; 
     } 

     @Override 
     public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) { 
      // do something 
      return true; 
     } 
    }) 
    .into(mCustomImageView); 

應用始終運行中onResourceReady或onException但如果我刪除偵聽器，並讓異步下載沒有回調，它正確地運行：

Glide.with(mContext) 
    .load(url) 
    .placeholder(R.drawable.glide_placeholder) 
    // use dontAnimate and not crossFade to avoid a bug with custom views 
    .dontAnimate() 
    .diskCacheStrategy(DiskCacheStrategy.ALL) 
    .into(mCustomImageView); 

我也試圖與GlideDrawableImageViewTarget代替監聽器接收回調，但應用程序運行內部onLoadStarted但從來沒有運行insid e onLoadCleared，onLoadFailed和onResourceReady。

Answer 1

這似乎是一個ImageView的可見性，如果它是不可見或消失的錯誤。我在這裏打開一個問題：https://github.com/bumptech/glide/issues/618

Answer 2

跑到同樣的問題。有onResourceReady返回false爲我做了詭計。

Answer 3

下面是做這件事：

 Glide.with(context).load(...) 
       .listener(object : RequestListener<Drawable> { 
        override fun onLoadFailed(e: GlideException?, model: Any?, target: Target<Drawable>?, isFirstResource: Boolean): Boolean { 
         //TODO handle error images while loading photo 
         return true 
        } 

        override fun onResourceReady(resource: Drawable?, model: Any?, target: Target<Drawable>?, dataSource: DataSource?, isFirstResource: Boolean): Boolean { 
         //TODO use "resource" as the photo for your ImageView 
         return true 
        } 

       }).submit()
