通用图像加载器-图像无法解码-> .imageDecoder问题

Question

我得到了错误E/ImageLoader﹕ Image can't be decoded。我在这里找到了一个解决方案https://github.com/nostra13/Android-Universal-Image-Loader/issues/539。有人说要复制一个类NutraBaseImageDecoder并将.imageDecoder(new NutraBaseImageDecoder(true))添加到选项中，但当我尝试添加此选项时，它无法识别.imageDecoder。我做错了什么？

这是我尝试过的：

 options = new DisplayImageOptions.Builder()
                    .showImageOnLoading(R.drawable.ic_empty)
                    .showImageForEmptyUri(R.drawable.ic_empty)
                    .showImageOnFail(R.drawable.ic_error)
                    .cacheInMemory(true)
                    .cacheOnDisk(true)
                    .imageDecoder(new NutraBaseImageDecoder(true))
                    .considerExifParams(true)
                    .displayer(new RoundedBitmapDisplayer(20)).build();

问题出在.imageDecoder(new NutraBaseImageDecoder(true))上。url中没有空格。当我在图像加载器中传递它时，我在Uri.decode(url)中也有它。

你不必把.imageDecoder(new NutraBaseImageDecoder(true))和DisplayImageOptions.Builder()放在一起，而是把ImageLoaderConfiguration放在下面这样：

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
            .discCacheFileNameGenerator(new Md5FileNameGenerator())
            .tasksProcessingOrder(QueueProcessingType.FIFO)
            .memoryCache(new WeakMemoryCache())
            .imageDecoder(new NutraBaseImageDecoder(true))
            .writeDebugLogs()
            .build();

ImageLoader.getInstance().init(config);
