我在eclipse中的windowbuilder創建的run（）方法中有計時器。如何停止該線程內的線程/定時器？
我不知道如何從另一種方法停止該計時器。例如，通過添加
if(MenuWindow.gameStarted == false) gameTimer.stop();
即是這裏，但是當我將其更改爲false時，它不會改變。它變爲false並返回true（我認爲）。
我改變變量從類MenuWindow
package krystofee.niggatycoon;
public class MenuWindow {
private static JFrame frame;
static boolean gameStarted;
static GameWindow game;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
MenuWindow window = new MenuWindow();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public MenuWindow() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
JButton btnNewButton = new JButton("Start");
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
GameWindow game = new GameWindow();
game.StartGame();
gameStarted = true;
frame.setVisible(false);
}
});
btnNewButton.setBounds(144, 154, 146, 43);
frame.getContentPane().add(btnNewButton);
}
public static void open() {
frame.setVisible(true);
game = null;
gameStarted = false;
}
}
而且有GameWindow
public class GameWindow<E> {
private JFrame frame;
static JProgressBar progressBar1;
static JButton upGardenerButton;
private Timer gameTimer;
public static Player player;
public static Worker worker;
private static JLabel labelMoney;
private JTable table;
private JLabel lblMultiplier;
boolean timerStop;
/**
* Create the application.
*/
public GameWindow() {
worker = new Worker(50, 75, 5000);
player = new Player();
initialize();
}
protected void endGame() {
frame.dispose();
timerStop = true;
}
public void StartGame() {
EventQueue.invokeLater(new Runnable() {
int gardenerTime = 0;
public void run() {
try {
GameWindow<Object> window = new GameWindow<Object>();
window.frame.setVisible(true);
ActionListener taskPerformer = new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
gardenerTime += 10;
progressBar1.setValue(gardenerTime);
if(gardenerTime >= worker.time) {
player.money.add(worker.getProfit());
gardenerTime = 0;
}
labelMoney.setText(player.money.getMoney()+"$");
if(gardenerTime % 100 == 0) System.out.println("Timer bezi. " + MenuWindow.gameStarted);
if(MenuWindow.gameStarted == false) gameTimer.stop();
}
};

gameTimer.start();
} catch (Exception e) {

看待問題GameWindow頂部，我改變gameStarted的價值封閉框架GameWindow後，它改變它爲false，所以它應該停止計時器...但是...不是。
你是對的！但它沒有解決這個問題。 +1 thx – Krystofee
