Android : Downloading and Displaying images simultaneously?

Question

I'm having a situation in my current project where I want to Download a wallpaper image from network. I want to download the image in chunks and at the same time display whatever image that has been downloaded in a ImageView. How to implement this? The type of Image that I would be downloading would be "PNG".

Answer 1

我认为一种解决方案是每次您要显示图像的新部分时，使用例如以下代码从字节数组创建图像：

BufferedImage image = ImageIO.read(in);

Answer 2

使用ImageView与imageView.setImageBitmap一起使用urlConnection下载文件，并将其inputStream插入BitmapFactory.decodeStram
