推荐答案

您的问题似乎有点不清楚要么您要求使用URL或任何内容阅读图像其他。如果是这样，您可以读取图像并将其设置为 ImageView ，就像这样

Your question seems a bit unclear Either you are asking for reading the image with URL or anything else. If so you can Read Image and set It to your ImageView like this way

InputStream in = (InputStream) new URL(imageUrl).getContent(); //Reads whatever content found with the given URL Asynchronously And returns.
                Bitmap bitmap = BitmapFactory.decodeStream(in); //Decodes the stream returned from getContent and converts It into a Bitmap Format
                yourImageView.setBitmap(bitmap); //Sets the Bitmap to ImageView
                in.close(); //Closes the InputStream

其中 imageUrl 是一个完整的URL，指向您的图像，如 something.com/image1.jpg

Where imageUrl is a complete URL which points to your Image like something.com/image1.jpg
