發送和接收TCP套接字android客戶端

Question

我寫了c＃客戶端服務器應用程序，服務器使用socket.send（byte []）發送數據並使用socket.receive（byte []）接收現在我想要發送和接收的數據android和全新的android。

我欣賞任何形式的幫助。

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

您可以使用一個TCP套接字和輸入流中從主應用程序線程獨立的線程在Android應用這樣的讀取數據：

// 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(); 
} 
}); 

可以在包裝輸入流各種其他類型的流，如果您想讀取多字節值（如短語或整數（DataInputStream））。這些將從網絡永恆性轉變爲客戶端的本地永久性。

您可以從套接字獲取輸出流以將數據寫回服務器。

希望這會有所幫助。
