我需要使用tcp socket連接才能從bluebox獲取數據,如果輸入註釋,比如「getcolor」,bluebox會給我發送像「red,blue」這樣的信息。 在這種情況下,藍盒作爲服務器,我不需要編程它,但我有問題顯示EditText上的信息。安卓tcp socket問題
public class sender {
public static void main(String[] args)throws IOException{
Socket socket = new Socket("192.168.1.176",14111);
OutputStream out = socket.getOutputStream();
BufferedReader msg = new BufferedReader(new InputStreamReader(System.in));
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter ou = new PrintWriter(new BufferedWriter(new OutputStreamWriter(out)),true);
String buffer = new String("");
String ms = "";
while(true)
{
while(in.ready())
buffer+= in.readLine()+ "\n";
String[] line = buffer.split("\n");
while(msg.ready())
ms = msg.readLine();
if(ms.equals("exit"))
{
break;
}
if(!ms.equals(""))
{
ou.println(ms);
ou.flush();
ms = "";
}
if(!buffer.equals(""))
{
System.out.print(buffer);
buffer = "";
}
}
in.close();
out.close();
socket.close();
}
}
這個java代碼工作,但它在下面的Android的代碼失敗:
public class BlueBoxApp extends Activity {
/** Called when the activity is first created. */
Context appInstance = this;
private EditText info;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
info = (EditText)findViewById(R.id.EditText01);
try{
InetAddress serverAddr = InetAddress.getByName("192.168.1.176");//TCP服務器IP地址
Log.d("TCP", "server,receiving...");
Socket socket = new Socket(serverAddr,14111);
try {
OutputStream out = socket.getOutputStream();
BufferedReader msg = new BufferedReader(new InputStreamReader(System.in));
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter ou = new PrintWriter(new BufferedWriter(new OutputStreamWriter(out)),true);
String buffer = new String("");
String ms = "getsensorno";
Log.d("TCP", "sending:'"+ms+"'");
while(true)
{
while(in.ready())
buffer+= in.readLine()+ "\n";
while(msg.ready())
ms = msg.readLine();
if(ms.equals("exit"))
{
break;
}
if(!ms.equals(""))
{
ou.println(ms);
ou.flush();
ms = "";
}
if(!buffer.equals(""))
{
info.setText(buffer);
buffer = "";
}
}
} catch (Exception e) {
Log.e("TCP", "error",e);
}finally{
socket.close();
}
}catch(Exception e){
Log.e("TCP", "error",e);
}
}
}
是什麼問題以及如何設置一個線程呢?謝謝!
什麼是例外?可能是它無法連接到模擬器的互聯網? – 2011-05-20 20:14:55
