此实例为本人原创的电话呼叫程序,用户输入号码进行拨号,由于本人一直是搞低级UI开发的,所以并没有用高级控件做输出体。
框架代码1 - Constant import javax.microedition.lcdui.Graphics; /** * @author 空白节奏 * */ public class Constant { public static final int SCR_WIDTH = 240; public static final int SCR_HEIGHT = 320; public static final int SCR_CENTERW = 120; public static final int SCR_CENTERH = 160; public static final byte FPS = 20; public static final String rms_name = "RMS_name"; //走程状态 public static int MIDLetState = 0; public static final int MIDLetState_LOGO = 1; public static final int MIDLetState_MENU = 2; public static final int KEY_UP = -1; public static final int KEY_DOWN = -2; public static final int KEY_LEFT = -3; public static final int KEY_RIGHT = -4; public static final int KEY_FIRE = -5; public static final int KEY_LSOFT = -6; public static final int KEY_RSOFT = -7; public static final int KEY_CLEAR = -8; public static final int KEY_SEND = -10; public static final int KEY_END = -11; public static final int KEY_ASTERISK = 42;// * public static final int KEY_POUND = 35;// # public static final int KEY_NUM0 = 48; public static final int KEY_NUM1 = 49; public static final int KEY_NUM2 = 50; public static final int KEY_NUM3 = 51; public static final int KEY_NUM4 = 52; public static final int KEY_NUM5 = 53; public static final int KEY_NUM6 = 54; public static final int KEY_NUM7 = 55; public static final int KEY_NUM8 = 56; public static final int KEY_NUM9 = 57; public static final int GLT = Graphics.LEFT | Graphics.TOP; public static final int GRT = Graphics.RIGHT | Graphics.TOP; public static final int GLB = Graphics.LEFT | Graphics.BOTTOM; public static final int GRB = Graphics.RIGHT | Graphics.BOTTOM; public static final int GTH = Graphics.TOP | Graphics.HCENTER; public static final int GBH = Graphics.BOTTOM | Graphics.HCENTER; public static final int GLV = Graphics.LEFT | Graphics.VCENTER; public static final int GRV = Graphics.RIGHT | Graphics.VCENTER; public static final int GHV = Graphics.HCENTER | Graphics.VCENTER; }
框架代码2 - GameMIDlet import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Displayable; import javax.microedition.midlet.MIDlet; /** * @author 空白节奏 * */ public class GameMIDlet extends MIDlet { static GameMIDlet gameMIDlet = null; Displayable current = null; GameMaster gm = null; public GameMIDlet() { gameMIDlet = this; } protected void startApp() { current = Display.getDisplay(this).getCurrent(); if(current == null) { gm = new GameMaster(this); Display.getDisplay(this).setCurrent(gm); } else { Display.getDisplay(this).setCurrent(current); } } protected void pauseApp() { } protected void destroyApp(boolean arg0) { } public static void quitApp() { gameMIDlet.destroyApp(true); gameMIDlet.notifyDestroyed(); gameMIDlet = null; } }
框架代码3 - GameMaster import javax.microedition.lcdui.Canvas; import javax.microedition.lcdui.Graphics; import javax.microedition.lcdui.Image; /** * @author 空白节奏 * */ public class GameMaster extends Canvas implements Runnable { private boolean isStart = false; private Image img_buffer = null; private Graphics gg; private boolean isFullScreen = true; call c = null; GameMIDlet gml = null; public GameMaster(GameMIDlet gml) { this.gml = gml; init(); setFullScreenMode(isFullScreen); isStart = true; new Thread(this).start(); } public void paint(Graphics g) { gg.setColor(0); gg.setClip(0, 0, Constant.SCR_WIDTH, Constant.SCR_HEIGHT); gg.fillRect(0, 0, Constant.SCR_WIDTH, Constant.SCR_HEIGHT); c.paint(gg); g.drawImage(img_buffer, 0, 0, Constant.GLT); } public void update() { c.updata(); } public void keyPressed(int keyCode) { } public void keyReleased(int keyCode) { } public void pointerPressed(int x, int y) { c.pointerPressed(x, y, gml); } public void init() { c = new call(); img_buffer = Image.createImage(Constant.SCR_WIDTH, Constant.SCR_HEIGHT); gg = img_buffer.getGraphics(); } long startTime = 0; long timeTaken = 0; public void run() { while (isStart) { startTime = System.currentTimeMillis(); update(); repaint(); timeTaken = System.currentTimeMillis() - startTime; if(timeTaken < 1000 / Constant.FPS) { try { Thread.sleep(1000 / Constant.FPS - timeTaken); } catch(Exception e) { e.printStackTrace(); } } } } }
逻辑代码 - call import java.util.Vector; import javax.microedition.io.ConnectionNotFoundException; import javax.microedition.lcdui.Graphics; /** * @author 空白节奏 * */ public class call { callButten[] cb = null; Vector v = new Vector(0, 1); String stError = ""; public call() { init(); } public void init() { cb = new callButten[13]; for(int i = 0; i < 3; i++) { for(int j = 0; j < 3; j++) { cb[(i*3)+j] = new callButten(1+(i*3)+j+"", 20+(j*40), 30+(i*50), 30, 30, -1, 0); } } cb[9] = new callButten("0", 150, 130, 30, 30, -1, 0); cb[10] = new callButten("拨打", 150, 30, 60, 30, -1, 0); cb[11] = new callButten("清除", 150, 80, 60, 30, -1, 0); cb[12] = new callButten("退出", 20, 220, 180, 30, -1, 0); } public void paint(Graphics g) { for(int i = 0; i < cb.length; i++) { cb[i].paint(g); } g.setColor(-1); g.fillRect(20, 180, 180, 30); if(v.size() > 0) { g.setColor(0); for(int i = 0; i < v.size(); i++) { g.drawString(v.elementAt(i).toString(), 22+(i*8), 182, 20); } } g.setColor(255,0,0); g.drawString(stError, 10, 20, 20); } public void updata() { } public void pointerPressed(int x, int y, GameMIDlet gm) { for(int i = 0; i < cb.length; i++) { if(x > cb[i].x && x < (cb[i].x + cb[i].width) && y > cb[i].y && y < (cb[i].y + cb[i].hight)) { if(i < 10) { v.addElement(cb[i].num); } else if(i == 10) { callplat(gm); } else if(i == 11) { if(v.size() > 0) v.removeElementAt(v.size()-1); } else if(i == 12) { gm.quitApp(); } } } } public void callplat(GameMIDlet gm) { String stURL = ""; for(int i=0; i<v.size(); i++) { stURL += v.elementAt(i).toString(); } try { if(!stURL.equals("")) { gm.platformRequest("tel:"+stURL); } } catch (ConnectionNotFoundException e) { stError = e.getMessage(); } } } class callButten { String num; int x, y, width, hight; int bgColor, strColor; callButten(){} callButten(String num, int x, int y, int width, int hight, int bgColor, int strColor) { this.num = num; this.x = x; this.y = y; this.width = width; this.hight = hight; this.bgColor = bgColor; this.strColor = strColor; } void paint(Graphics g) { g.setColor(bgColor); g.fillRect(x, y, width, hight); g.setColor(strColor); g.drawString(num, x+(width>>1)-5, y+(hight>>1)-5, 20); } }
实现了J2ME的打电话功能,需要MIDP2.0支持,需注意的是,有些机器不支持platformRequest方法,比如我的E680G就不支持,并且API对此方法的描述也是雷人,- - 大概意思是“此方法应该能够拨打指定电话号码”,应该二字很雷人。

googya 写道 啪啪啪一段代码!有点说明是否更好?!
实在不知道该说明点啥好,因为这段代码太容易看懂了,需要注意点地方我写上了啊~ 以后我会多多说明的~ 感谢提醒 |
