我可以在展示之前用Picasso下载图像吗？我想先缓存图像.

示例场景:用户单击按钮,查看进度条,图像加载完成后,用户可以在屏幕上看到图像.

            RequestCreator picassoRequest;
            for (String imgUrl : imagesUrls) {
                picassoRequest = picasso.load(imgUrl);
                picassoRequest.get();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
};

thread.start();

这是我的毕加索单身课程

public class PicassoOwnCache {
    static Picasso singleton = null;
    static Cache cache = null;

    public static Picasso with(int cacheSize, Context context) {
        if (singleton == null) {
            int maxSize = calculateMemoryCacheSize(context);
            cache = new LruCache(cacheSize <= …
