没有找到适合 into(Uri) 的方法

Question

我想允许用户上传两张图片，封面和徽标。然后将它们保存在 firestore 中。我收到一个错误 Picasso.get().load(uri).into(Logo);线说

没有找到适合 into(Uri) 的方法 方法 RequestCreator.into(Target) 不适用 （参数不匹配；Uri 无法转换为 Target） 方法 RequestCreator.into(ImageView) 不适用 （参数不匹配；Uri 无法转换为 ImageView）

在你的代码中 Logo 是 Uri 你需要这个：

Picasso.get().load(uri).into(imageView);

imageView 是布局中的 ImageView 对象
