android udp 只能显示第一张图片的问题

我写的不全，现在只能分开发送一张图片，你可以参考下

我还没找到
那你第一张图片怎么恢复的呢？？我找了很多都不是UDP的。。加个QQ探讨一下吧
第一张图片的那些UDP包在接收端是怎么循环接收的呢？byte[] recvBuffer = null;
    int MSG_LEN = 8192;
    DatagramPacket recvPacket;

    public void run() {
     try {
DatagramSocket msg_socket =new DatagramSocket(34321);
recvBuffer = new byte[MSG_LEN];
recvPacket = new DatagramPacket(recvBuffer, recvBuffer.length);
//System.out.println("sdf");
System.out.println("wrong?");
msg_socket.receive(recvPacket);
//view.setText(new String(recvPacket.getData()));

//view.setText(new String(recvPacket.getData()));
//view.setText("w:"+text.getText().toString());
       Message msgMessage=Message.obtain();

        msgMessage.obj = recvPacket.getData();

        msgMessage.what = IS_FINISH;
        handler.sendMessage(msgMessage);

} catch (SocketException e) {
//Toast.makeText(MainActivity.this, e.toString(), Toast.LENGTH_LONG).show();
e.printStackTrace();
} catch (IOException e) {
//Toast.makeText(MainActivity.this, e.toString(), Toast.LENGTH_LONG).show();
e.printStackTrace();
}
我的代码是这样，现在只能接一个包吧应该。所以想问一下怎么用循环接收这张图片的这些UDP包

调试易
