Android 图片三级缓存

为什么80%的码农都做不了架构师？>>>   

public class MemoryCache {

    private LruCache<String, Bitmap> lruCache;

    public MemoryCache() {

        lruCache = new LruCache<String, Bitmap>((int)(Runtime.getRuntime().maxMemory()/8)) {

            protected int sizeOf(String key, Bitmap bitmap) {

                return bitmap.getByteCount();

            }

        }

    }

    public void put(String key, Bitmap bitmap) {

        lruCache.put(key, bitmap);

    }

    public Bitmap get(String key) {

        lruCache.get(key);

    }

}
