我通过创建和使用以下函数在后台缓存图像来解决该问题 在ImageLoader.java中

I solved it by caching the image in background by creating and using the following function in ImageLoader.java

public void cacheImage(String url){
    Bitmap bmp = getBitmap(url);
    memoryCache.put(url, bmp);
}

我创建了一个ImageLoader实例，对其进行了静态引用，然后调用

I created one instance of ImageLoader, made a static reference to it and then called

AsyncClass.imageLoader.cacheImage(url);

AsyncClass.imageLoader.cacheImage(url);

AsyncClass是我对ImageLoader进行静态引用并将其称为"imageLoader"的类.

Where AsyncClass is the class where I made the static reference to the ImageLoader and called it "imageLoader".
