如何通过套接字发送多个图像 [英] java How to send a multiple images over socket

问题描述

通过套接字将多个图像从java服务器发送到android客户端，麻烦你只看到最后一张图片。

我从java服务器向android发送多个图像的大问题通过套接字和所有图像发送都很好，但接收它们的问题，我只看到最后一个。



服务器java端：

send multiple images over socket from java server to android client,trouble that you'll see just last image.
My big problem that i send multiple images from java server to android clent over socket and all the images sending fine, but the problem with receive them, i see just the last one .

Server java side :

//during the connecting
private void whileConnecting() throws IOException, AWTException, InterruptedException {  
    int i=0;
    while(i<5){
    System.out.println("i = " + i);
    capture = robot.createScreenCapture(screenRectangle);
    baos = new ByteArrayOutputStream();
    ImageIO.write(capture, "png", baos);
    baos.flush();
    System.out.println("Size of baos = " + baos.size());
    byte[] buffer = baos.toByteArray();
    baos.close();
    baos = null;
    output.writeObject(buffer);
    output.flush();
    i++;
    Thread.sleep(1000);
    }
}

客户端android端：

Client android Side :

try {
       connection = new Socket(getIntent().getStringExtra("ip"), 8080);
       input = new ObjectInputStream(connection.getInputStream());
       int i = 0;
       while (i < 5) {
           i++;
           buffer = (byte[]) input.readObject();
           Toast.makeText(getApplicationContext(), "buffer length = " + buffer.length, Toast.LENGTH_LONG).show();
               //screenCapture.setImageBitmap(BitmapFactory.decodeByteArray(buffer, 0, buffer.length));
           }
         } catch (ClassNotFoundException e) {
           e.printStackTrace();
         } catch (IOException e) {
           e.printStackTrace();
         }finally {
         try {
             connection.close();
         } catch (IOException e) {
             Toast.makeText(getApplicationContext(), "Error with closing connection", Toast.LENGTH_LONG).show();
         }
     }  

所有图片都是成功发送的，我看到了他们在吐司的信息大小和真相，但我看到的问题只是最后一张图片！为什么，我认为我应该使用syncTask或类似的东西，但我不知道如何:(

有人可以帮忙请求吗？

all the images are sent successfuly , i saw the size of them on toast message and that truth, but the problem that i saw just the last image ! why, i think that should i use syncTask or something like that but i dont know how :(
can someone help pleas ?
