解决方案,复制
HttpUrlConnectionNetworkFetcher类中的代码,新建一个类叫做CustomImageDownloaderFetcher,将fetchSync()方法中的
callback.onResponse(is, -1);改为callback.onResponse(is, connection.getContentLength());
再在初始化Fresco时,传入自定义类ImagePipelineConfig.
newBuilder
(context).setNetworkFetcher(
new
CustomImageDownloaderFetcher())
