小弟寫ㄌ一個程式,...但連續撥放與停止撥放寫不出來,.. 以下是我ㄉ程式碼...麻煩邦小弟看一下如何解決好嗎?? import java.awt.event.*; import java.awt.*; import java.applet.*; import javax.swing.*; public class image extends Frame implements ActionListener{ private Image Pic[] = new Image[3]; int Count,Count2,Count3; //產生Button物件 Button one = new Button("上一張"); Button two = new Button("下一張"); Button three = new Button("連續撥放"); Button four = new Button("停止撥放"); Button five = new Button("關閉程式"); TextField Num= new TextField(""); public image() { setBackground(Color.black); //設定背景顏色為黑色 //以下設定視窗的大小 setBounds(100,100,850,625); setLayout(null); //以下讀載入圖檔 for(int Count = 0; Count < 3; Count ){ Count2 = Count 1; Pic[Count] = Toolkit.getDefaultToolkit().getImage(Count2 ".jpg"); } //以下設定按鈕範圍(x,y,長,寬) one.setBounds(10, 100, 55, 25); two.setBounds(10, 130, 55, 25); three.setBounds(10, 160, 55, 25); four.setBounds(10, 190, 55, 25); five.setBounds(10, 220, 55, 25); Num.setBounds(10, 70, 55, 25); //委託事件 one.addActionListener(this); two.addActionListener(this); three.addActionListener(this); four.addActionListener(this); five.addActionListener(this); add(one); //加入按鈕one add(two); //加入按鈕two add(three); //加入按鈕three add(four); //加入按鈕four add(five); //加入按鈕five add(Num); //加入按鈕Num setVisible(true); //顯示視窗 Count2 = 1; //預設顯示次數 Num.setText("第" Count2 "張圖"); } //按鈕按下後的動作 public void actionPerformed(ActionEvent evn){ Object result = (Object)evn.getSource(); if (result == one){ if (Count == 0){ } else { Count--; } } if (result == two){ if (Count == 2){ } else { Count ; } } if (result == three){ } if (result == four){ Count3 = 3; } if (result == five){ System.exit(0); } Count2 = Count 1; Num.setText("第" Count2 "張圖"); repaint(); } //畫上圖示 public void paint(Graphics g){ g.drawImage(Pic[Count], 70, 20, this); } public static void main(String argv[]) { new image(); } }
