Android與PC的socket通信

  我們今天就來說說android怎麼樣才能和PC通信，這個我們就要用到socket了，那麼我們現在就來用一個小例子來看看。在代碼中我都用了註釋，希望大家來看看我發的帖子。

java代碼：

1. import java.io.BufferedReader;
   
2. import java.io.BufferedWriter;
   
3. import java.io.IOException;
   
4. import java.io.InputStreamReader;
   
5. import java.io.OutputStreamWriter;
   
6. import java.net.ServerSocket;
   
7. import java.net.Socket;
   
8. 
   
9. public class YaoChatServer extends Thread {
   
10. 
    
11. private YaoChatServer() throws IOException {
    
12. CreateSocket();
    
13. //創建Socket服務器
    
14. }
    
15. 
    
16. public void run() {
    
17. Socket client;
    
18. String txt;
    
19. try {
    
20. while (true)
    
21. //線程無限循環，實時監聽socket端口
    
22. {
    
23. client=ResponseSocket();
    
24. //響應客戶端鏈接請求。。
    
25. 
    
26. while(true)
    
27. {
    
28. txt=ReceiveMsg(client);
    
29. System.out.println(txt);
    
30. //鏈接獲得客戶端發來訊息，並將其顯示在Server端的螢幕上
    
31. 
    
32. SendMsg(client,txt);
    
33. //向客戶端返回訊息
    
34. 
    
35. if(true)break;
    
36. //中斷，繼續等待鏈接請求
    
37. }
    
38. 
    
39. CloseSocket(client);
    
40. //關閉此次鏈接
    
41. }
    
42. }
    
43. catch (IOException e) {
    
44. System.out.println(e);
    
45. }
    
46. 
    
47. }
    
48. 
    
49. private ServerSocket server = null;
    
50. private static final int PORT = 5000;
    
51. private BufferedWriter writer;
    
52. private BufferedReader reader;
    
53. 
    
54. private void CreateSocket() throws IOException
    
55. {
    
56. server = new ServerSocket(PORT, 100);
    
57. System.out.println("Server starting..");
    
58. }
    
59. 
    
60. private Socket ResponseSocket() throws IOException
    
61. {
    
62. Socket client = server.accept();
    
63. System.out.println("client connected..");
    
64. 
    
65. return client;
    
66. }
    
67. 
    
68. private void CloseSocket(Socket socket) throws IOException
    
69. {
    
70. reader.close();
    
71. writer.close();
    
72. socket.close();
    
73. System.out.println("client closed..");
    
74. }
    
75. 
    
76. private void SendMsg(Socket socket,String Msg) throws IOException
    
77. {
    
78. writer = new BufferedWriter(
    
79. new OutputStreamWriter(socket.getOutputStream()));
    
80. writer.write(Msg+"\n");
    
81. writer.flush();
    
82. 
    
83. }
    
84. 
    
85. private String ReceiveMsg(Socket socket) throws IOException
    
86. {
    
87. reader = new BufferedReader(
    
88. new InputStreamReader(socket.getInputStream()));
    
89. System.out.println("server get input from client socket..");
    
90. String txt="Sever send:"+reader.readLine();
    
91. 
    
92. return txt;
    
93. }
    
94. 
    
95. public static void main(final String args[]) throws IOException {
    
96. YaoChatServer yaochatserver = new YaoChatServer();
    
97. if (yaochatserver != null) {
    
98. yaochatserver.start();
    
99. }
    
100. }
     
101. 
     
102. }
