修改代码以通过套接字发送多个文件

问题描述

我是android开发的初学者，我对如何修改我的代码以通过套接字发送 多个文件 有疑问，使用我当前的代码我只能发送一次一个文件，我有一个ArrayList，它是从其他活动中获得的，其中包含要发送的文件的完整路径，但是当我向数组中添加多个文件时，它不会发送任何内容。整整一个月困扰着我 任何帮助或建议将不胜感激

这是我的发件人代码

@Override
public void run() {

Intent intent = getIntent();
Bundle bundle = intent.getExtras();  //Receiving Intent from other Activity
ArrayList send = (ArrayList) bundle.getParcelableArrayList("send"); //Full path of file in ArrayList
ArrayList name = (ArrayList) bundle.getParcelableArrayList("name"); //Name of the file if Available 
String con = send.toString();
String convert = con.replaceAll("\\[","").replaceAll("\\]","");
file = new File(convert);

byte[] bytes = new byte[(int) file.length()];
BufferedInputStream bis;
try {
   bis = new BufferedInputStream(new FileInputStream(file));
   DataInputStream dis = new DataInputStream(bis);
   OutputStream os = socket.getoutputStream();
   DataOutputStream dos = new DataOutputStream(os);
   if (name == null){
      dos.writeUTF(file.getName());
   }else {
      String conname = name.toString();
      String convertname = conname.replaceAll("\\[","");
      dos.writeUTF(convertname + ".apk");
  }

  int read;
  while ((read = dis.read(bytes)) != -1){
        dos.write(bytes,read);
  }

  socket.close();
}

这是接收者的

@Override
public void run() {

Socket socket = null;
int bytesRead;
InputStream in;
int bufferSize = 0;

try {
    socket = new Socket(dstAddress,dstPort);
    bufferSize = socket.getReceiveBufferSize();
    in = socket.getInputStream();
    DataInputStream clientData = new DataInputStream(in);
    String fileName = clientData.readUTF();
    File file = new File(Environment.getExternalStorageDirectory()  + fileName);  //Name and place of file to be save
    OutputStream output = new FileOutputStream(file);
    byte[] buffer = new byte[bufferSize];
    int read;
    while ((read = clientData.read(buffer)) != -1) {
          output.write(buffer,read);
    }

    socket.close();

}
