第一步：编写文件缓存的相关方法，关于Software缓存类在网上可以搜索到相关的资料（文件缓存工具类）
public class AsyncImageLoader {

}
// 第一种方法
// public Bitmap loadBitmap(final ImageView imageView, final String
// imageURL, final ImageCallBack imageCallBack)
// {
// //在内存缓存中，则返回Bitmap对象
// if(imageCache.containsKey(imageURL))
// {
// SoftReference<Bitmap> reference = imageCache.get(imageURL);
// Bitmap bitmap = reference.get();
// if(bitmap != null)
// {
// return bitmap;
// }
// }
// else
// {
// /**
// * 加上一个对本地缓存的查找
// */
// //截取上传的文件名称
// String bitmapName = imageURL.substring(imageURL.lastIndexOf("/") + 1);
// //文件的存放地址
// File cacheDir = new File("/mnt/sdcard/test/");
// // if(!cacheDir.exists()){
// // cacheDir.mkdirs();
// // }
// //文件数组
// File[] cacheFiles =cacheDir.listFiles();
// if(cacheFiles!=null){
