There is no image path, as there is no requirement that this Uripoint to a file, let alone point to a file that you have direct filesystem access to.
没有图像路径，因为不需要它Uri指向文件，更不用说指向您可以直接访问文件系统的文件了。
Use an image-loading library (e.g., Glide, Picasso) and provide it the Urithat you get from WhatsApp. Those libraries know how to use ContentResolverand openInputStream()to read in the bytes associated with that content, convert those bytes into a Bitmapusing BitmapFactory.decodeStream(), and put the Bitmapinto your ImageView.
使用图像加载库（例如 Glide、Picasso）并提供Uri您从 WhatsApp 获得的图像。这些库知道如何使用ContentResolver，并openInputStream()在与该内容相关联的读取字节，这些字节转换为Bitmap使用BitmapFactory.decodeStream()，并把Bitmap到你ImageView。
