Question

我写了c＃client-server应用程序，服务器使用socket.send（byte []）发送数据并使用socket.receive（byte []）接收现在我想从android发送和接收并且完全是新的android。

我感谢任何帮助。

Answer 1

//client side        
        Socket sendChannel=new Socket("localhost", 12345);
        OutputStream writer=sendChannel.getOutputStream();
        writer.write(new byte[]{1});
        writer.flush();

        InputStream reader=sendChannel.getInputStream();
        byte array[]=new byte[1];
        int i=reader.read(array);

//server side
        ServerSocket s=new ServerSocket(12345);
        Socket receiveChannel = s.accept();

        OutputStream writerServer=receiveChannel.getOutputStream();
        writer.write(new byte[]{1});
        writer.flush();

        InputStream readerServer=receiveChannel.getInputStream();
        byte array2[]=new byte[1];
        int i2=reader.read(array);

您可以使用TCP套接字和输入流在Android应用程序中的主应用程序线程的单独线程中读取数据，如下所示：

// Start a thread
new Thread(new Runnable() {
 @Override
 public void run() {
 // Open a socket to the server
 Socket socket = new Socket("192.168.1.1", 80);
 // Get the stream from which to read data from
 // the server
 InputStream is = socket.getInputStream();
 // Buffer the input stream
 BufferedInputStream bis = new BufferedInputStream(is);
 // Create a buffer in which to store the data
 byte[] buffer = new byte[1024];
 // Read in 8 bytes into the first 8 bytes in buffer
 int countBytesRead = bis.read(buffer, 0, 8);
 // Do something with the data

 // Get the output stream from the socket to write data back to the server
 OutputStream os = socket.getOutputStream();
 BufferedOutputStream bos = new BufferedOutputStream(os);
 // Write the same 8 bytes at the beginning of the buffer back to the server
 bos.write(buffer, 0, 8);
 // Flush the data in the socket to the server
 bos.flush();
 // Close the socket
 socket.close();
}
});

如果要读取多字节值（如short或ints（DataInputStream）），可以将输入流包装在各种其他类型的流中。这些将负责从网络endianess转换为客户端的本机endianess。

您可以从套接字获取输出流，以将数据写回服务器。

希望这有帮助。
