在(1)中,实现了Windows服务端与Android客户端的连接,本节将实现在Windows服务端与Android客户端之间传递数据。
Android客户端的发送线程SendThread.java代码:
package com.hzhi.mouse_mb; import java.io.DataOutputStream;
import java.net.Socket; import android.os.Bundle;
import android.os.Message;
import android.util.Log; public class SendThread extends Thread { public static Socket socket_client;
public static String str_mk; // DOS
DataOutputStream dos = null; // 消息变量
private Message msg;
private Bundle bdl; public SendThread(Socket skt){ socket_client = skt; } public void set_str(String str){ str_mk = str; } public void run(){ try
{
dos = new DataOutputStream(socket_client.getOutputStream());
}
catch (Exception e)
{
send_message(MainActivity.msg_error,e.toString());
} while(true){ try
{
if(str_mk == null)
{
continue;
}
else
{
dos.writeUTF(str_mk);
Log.i("str_mk=", str_mk);
str_mk = null;
}
}
catch (Exception e)
{
send_message(MainActivity.msg_error,e.toString());
} } } // 发送消息(用于更新UI)
public void send_message(int x, String s){ msg = new Message();
bdl = new Bundle();
bdl.putString("1",s);
msg.what = x;
msg.setData(bdl);
MainActivity.main_handler.sendMessage(msg); } }
dos = new DataOutputStream(socket_client.getOutputStream())获得了一个DataOutputStream,socket_client.getOutputStream()获得了将数据写入socket_client的OutputStream,并将该OutputStream作为dos的OutputStream;在while(true)循环中,dos.writeUTF(str_mk),将字符串str_mk写入socket_client,发送给服务端的Socket。
Windows服务端的接收线程tReceive.java代码:
import java.io.DataInputStream;
import java.net.Socket; public class tReceive extends Thread{ public static Socket sct;
String str_mk; public tReceive(Socket s) {
super("");
this.sct = s;
} public void run() { DataInputStream dis = null; try
{
dis = new DataInputStream(sct.getInputStream());
}
catch (Exception e)
{
fMain.l_status.setText("错误:" + e);
} while(true)
{ try
{
str_mk = dis.readUTF();
System.out.println("str_mk=" + str_mk);
fMain.rbt_act(str_mk);
}
catch (Exception e)
{
fMain.l_status.setText("错误:" + e);
} } } }
dis = new DataInputStream(sct.getInputStream()) 获得了一个DataInputStream;sct.getInputStream()) 获得了sct的InputStream,并将该InputStream作为DataInputStream的InputStream;在while(true)循环中,dis.readUTF()读出sct中的数据,并赋值给字符串变量str_mk。
