android volley ImageLoader+ImageCache+LruCache内存缓存的
Volley是Google在Google I/O 上发布的一个网络框架,主要功能:web接口请求,码v码分网络异步下载,码v码分财务分析源码公式支持缓存。码v码分volley只是码v码分cout底层实现源码定义了缓存以及Request的接口,具体实现可以自己定义,码v码分java芋道源码例如lru磁盘缓存,码v码分内存缓存,码v码分下载的ImageRequest.
Volley的源代码里包含了一些实现,都在com.Android.volley.toolbox包里,码v码分包括磁盘缓存、码v码分json请求,码v码分请求。还定义了一个继承自ImageView的码v码分NetworkImageView,可以异步载入网络。
