ImageLoader使用

最近琢磨的网上的这些开源框架，imageLoader确实很好用，基本用法不记录了，参考网上的一些代码写了个ImageLoaderManager

 public class ImageLoaderManager {
     public static DisplayImageOptions.Builder IMAGE_OPTION_DEFAULT = new DisplayImageOptions.Builder()
             .cacheInMemory(true).cacheOnDisk(true).displayer(new SimpleBitmapDisplayer())
             .resetViewBeforeLoading(true).considerExifParams(true).bitmapConfig(Bitmap.Config.RGB_565);

     public static DisplayImageOptions IMAGE_OPTION_DEFAULT_PIC = IMAGE_OPTION_DEFAULT
             .showImageForEmptyUri(R.drawable.ic_launcher)
             .showImageOnFail(R.drawable.ic_launcher)
             .showImageOnLoading(R.drawable.ic_launcher)
             .build();

     public static void init(Context context){
         ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context).
                 memoryCacheExtraOptions(480, 800).   //max width, max height
                 threadPoolSize(3).                    //线程池内加载的数量
                 threadPriority(Thread.NORM_PRIORITY).denyCacheImageMultipleSizesInMemory().
                 memoryCache(new LruMemoryCache(2 * 1024 * 1024)).   //you can pass your own memory cache implementation
                 memoryCacheSize(2 * 1024 * 1024).
                 diskCacheSize(50 * 1024 * 1024)
                 .diskCacheFileNameGenerator(new Md5FileNameGenerator())//将保存的时候的URI名称用MD5 加密
                 .tasksProcessingOrder(QueueProcessingType.LIFO)
                 .diskCacheFileCount(100) //缓存的文件数量
                 .diskCache(new UnlimitedDiskCache(StorageUtils.getCacheDirectory(context)))//自定义缓存路径
                 .defaultDisplayImageOptions(IMAGE_OPTION_DEFAULT.build())
                 .imageDownloader(new BaseImageDownloader(context, 5 * 1000, 30 * 1000)) // connectTimeout (5 s), readTimeout (30 s)超时时间
                 .build();//开始构建
         ImageLoader.getInstance().init(config);//全局初始化此配置
     }
 }

我们需要在全局初始化这个ImageLoader，所以在application类中我们需要init

 public class MyApplication extends Application{

     private static MyApplication instance;

     public static MyApplication getInstance(){
         return instance;
     }

     @Override
     public void onCreate() {
         super.onCreate();

         instance = this;
         initImageLoader();
     }

     private static void initImageLoader(){
         ImageLoaderManager.init(instance.getApplicationContext());
     }

调用时只需要一行代码

    public void setImage(String url){
        ImageLoader.getInstance().displayImage(url, image, ImageLoaderManager.IMAGE_OPTION_DEFAULT_PIC);
    }

image为imageview
