java - Picasso 中的错误 get() 无法应用于 (android.content.Context)

Question

我正在构建一个应用程序，当我尝试发布 apk 时，我从 Picasso 中的 mContext 收到此错误，我在 gradle 中添加了实现 com.squareup.picasso:picasso:2.5.2 但仍然存在问题，我将 With() 替换为 get() ，同样的问题:

get( )in Picasso cannot be applied to(android.content.Context)

Answer 1

只需使用:

Picasso.get()
  .load(new File(thumbPath))
  .into(imageView);
