毕加索始终支持占位符和错误图像:

Picasso supports placeholder and error images anyways:

Picasso.get()
    .load(url)
    .placeholder(R.drawable.user_placeholder)
    .error(R.drawable.user_placeholder_error)
    .into(imageView);

因此，如果您要归档的只是显示一些错误图像，则在加载不起作用时，这就是您所需要的.

So, if all you want to archieve, is to show some error image, when loading does not work, that is all you need.
