我正在使用此代码从网络加载图像。
我同时发出多个请求，因此出现错误 FileNotFound 但文件实际上存在于服务器上。
因此我想问一下，如果 Glide 失败，我该如何重试 Glide 请求？
public static void LoadNetworkImage(final Context context, final ImageView imageView, final String imageUrl) {
Glide.with(context).
load(imageUrl).
listener(new RequestListener<Drawable>() {
@Override
public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
//if loading fails then again make request
LoadNetworkImage(context,imageView,imageUrl);
return true;
}
@Override
public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
return false;
}
}).
into(imageView);
}
我研究过这个讨论How to retry image loading ,if Glide fails?但这没有帮助。

最佳答案
这是图书馆 Weak Handler
1.将这个库添加到build.gradle文件中。
2.代码如下。
代码
public static void LoadNetworkImage(final Context context, final ImageView imageView, final String imageUrl) {
final WeakHandler mHandler = new WeakHandler();
final Runnable runnable = new Runnable() {
@Override
public void run() {
LoadNetworkImage(context, imageView,imageUrl);
}
};
Glide.with(context).
load(imageUrl).
transition(DrawableTransitionOptions.withCrossFade()).
listener(new RequestListener<Drawable>() {
@Override
public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
mHandler.postDelayed(runnable,1);
return true;
}
@Override
public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
return false;
}
}).
into(imageView);
}
注意 如果您的图像加载失败，则此代码将在 1 MiiliSecond 失败后发送请求。仅因为您说过该资源存在，这对您的情况最有效。
警告 但如果资源不存在，那么这不是最佳解决方案。因为递归会无限进行下去。
