I would like to print text by default in a textview before I wait for
a socket connection. When a connection is established I would like to
receive messages from the client and print them to the screen.
Hence I would like to first have one message printed and change this
dynamiclly as time goes. The problem is that nothing is written to the
screen until Oncreate() has ended.
Please help me!
Code:
-------------
package com.example.ComEx;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class ComEx extends Activity {
/** Called when the activity is first created. */
private TextView t;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Socket kkSocket=null;
PrintWriter out;
BufferedReader in;
t = (TextView) findViewById(R.id.textTest);
printIt("Test the client layout");
try {
kkSocket = new Socket("10.0.2.2", 5000);
} catch (UnknownHostException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
out = new PrintWriter(kkSocket.getOutputStream(), true);
in = new BufferedReader(new InputStreamReader(
kkSocket.getInputStream()));
out.println("Hej Oskar");
String fromServer;
while ((fromServer = in.readLine()) != null) {
printIt("Server "+fromServer);
if (fromServer.equals("Bye."))
break;
}
}catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private void printIt(String s){
t.setText(new StringBuffer(s));
}
}
