我有在java中从屏幕捕获图像的代码，我将最终捕获的图像作为 BufferedImage 对象并可以将其转换为 ImageIcon
问题是当将该文件发送到 android 时无法将其读取为可绘制的位图。有人对此有答案吗？
要发送的代码 (Java)
BufferedImage image = robot.createScreenCapture(rectangle);
ImageIcon imageIcon = new ImageIcon(image);
//Send captured screen to the server
try {
System.out.println("before sending image");
oos.writeObject(imageIcon);
oos.reset(); //Clear ObjectOutputStream cache
System.out.println("New screenshot sent");
} catch (IOException ex) {
ex.printStackTrace();
}
安卓接收器部分
Thread t= new Thread(new Runnable() {
@Override
public void run() {
while (true) {
try {
client= sc.accept();
is = client.getInputStream();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
BitmapDrawable imageIcon = null;
try {
ois = new ObjectInputStream(is);
imageIcon = (BitmapDrawable) ois.readObject();
//Drawable d = Drawable.createFromStream(is, null);
IV.setImageDrawable(imageIcon);
} catch (OptionalDataException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("New image recieved");
}
}
我得到的例外是它不能将 imageIcon 或 BufferedImage 转换为 Bitmap drawable。
