发送和接收TCP套接字android客户端

Question

我写了c＃客户端服务器应用程序，服务器使用socket.send（byte []）发送数据并使用socket.receive（byte []）接收现在我想要发送和接收的数据android和全新的android。

我欣赏任何形式的帮助。

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); 

Answer 2

您可以使用一个TCP套接字和输入流中从主应用程序线程独立的线程在Android应用这样的读取数据：

// 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(); 
} 
}); 

可以在包装输入流各种其他类型的流，如果您想读取多字节值（如短语或整数（DataInputStream））。这些将从网络永恒性转变为客户端的本地永久性。

您可以从套接字获取输出流以将数据写回服务器。

希望这会有所帮助。
