我正在尝试使用TrayIcon在Windows 8.1中显示基本的系统托盘消息。然而,当我运行程序时,什么也没有显示出来。以下是代码:
package alert1;
import java.net.*;
import java.io.*;
import java.util.*;
import java.awt.*;
import javax.imageio.*;
public class Main {
public static void main(String[] args) throws IOException {
URL gfl = new URL("http://gflclan.com/GFL/serverlist.php");
BufferedReader in = new BufferedReader(new InputStreamReader(gfl.openStream()));
Image img = ImageIO.read(new File("gflicon.jpg"));
TrayIcon tray = new TrayIcon(img);
System.out.println("Enter name of map: ");
Scanner scan = new Scanner(System.in); //retrieves name of map from IO
String str = scan.nextLine();
scan.close();
//pL = previousLine
String pL1 = null; //line which contains the server name
String pL2 = null;
String pL3 = null;
String pL4 = null; //line which contains the server IP
String pL5 = null;
String currentLine;
while ((currentLine = in.readLine()) != null)
if(currentLine.contains(str)){
String pL1fixed = pL1.replaceAll("\\<.*?\\> ?", "").trim(); //removes HTML/CSS formatting
String pL4fixed = pL4.replaceAll("\\<.*?\\> ?", "").trim();
System.out.println("Server Name: " + pL1fixed);
System.out.println("Server IP: " + pL4fixed);
tray.displayMessage("Server Found", "[Server Info Here]", TrayIcon.MessageType.WARNING);
} else {
pL1 = pL2; //updates stream's line history
pL2 = pL3;
pL3 = pL4;
pL4 = pL5;
pL5 = currentLine;
}
in.close();
}
}
我有点不明白,就我所知道的,我已经拥有了TrayIcon对象并对其进行了displayMessage调用,但我不知道为什么它没有显示出来。这是我第一次编写Java项目,也是我第一次使用图片处理,如果我的代码很业余,请谅解。
