我已经尝试过无效的缓存。清洁构建和重建项目也已完成。 但我仍然得到未解决的参考：用 我使用毕加索图书馆，我的其他活动工作正常。毕加索图书馆已在gradle中实施。 语言版本为1.2 Android Studio

问题出现在这里：Picasso.with
if (!image!!.equals("default")) {
Picasso.with(applicationContext)
.load(image)
.placeholder(R.drawable.profile_img)
.into(settingsProfileID)
}
我该如何解决这个问题？
答案 0 :(得分：1)
今晚我遇到了同样的问题，查看了毕加索网站后，我发现.with不再使用。 .get（）工作正常。尝试这样的事情。
Picasso.get()
.load(url)
.placeholder(R.drawable.user_placeholder)
.error(R.drawable.user_placeholder_error)
.into(imageView);
我的代码看起来像这样
val thumbnailImage = holder.view.imageView_Video_Thumbnail
Picasso.get().load(movieTitle.imageUrl).into(thumbnailImage)
希望能帮助某人。
