工艺技术_moto手机开发的一些问题汇总

moto手机开发的一些问题汇总1,怎么样程序知道是运行在模拟器上还是在手机上 看IMEI号。一般手机按*#06#就可得到imei码，每个手机是唯一的。 public void paint(Graphics g) g.drawString(Phone Parameter:,0, 0, 16|4); g.drawString(IMEI:,0, 30,16|4); g.drawString(System.getProperty(phone.imei),0, 60,16|4); g.drawString(Network Parameter:,0, 90, 16|4); g.drawString(MCC:+System.getProperty(phone.mcc),0, 120,16|4); g.drawString(MNC:+System.getProperty(phone.mnc),0, 150, 16|4); g.drawString(LAI:+System.getProperty(phone.lai),0, 180, 16|4); g.drawString(CID:+System.getProperty(phone.cid),0, 210, 16|4); 2 看别人的game源代码时，找不到resource(图片)的原因， 如果你还没有添加一个叫做J2ME_RESOURCE_DIR的新的环境变量的话,建立他,具体步骤如下: win98下：编辑c:autoexec.bat文件，加入set J2ME_RESOURCE_DIR=你的工程目录，重起系统。 win2k下：我的电脑-属性-高级-环境变量-系统-添加-名称：J2ME_RESOURCE_DIR 内容：你的工程目录 配好后，每当你在jcreator中打开时，就自动转向你的J2ME_RESOURCE_DIR所指定的目录 3 四级灰度的颜色值怎么表示？ private final static int WHITE_COLOR = 0x00FFFFFF; private final static int LIGHT_GRAY = 0x; private final static int DARK_GRAY = 0x; private final static int BLACK_COLOR = 0x; 4 关于开发工具 MotoJ2SDK是为摩托罗拉388手机定制的命令行开发工具包，当然也可与IDE开发工具集成从而方便用户的开发。其中可以集成的开发环境包括：CodeWarrior, JCreator等。 另外SUN公司还提供了Java的开发工具，J2ME Wireless Tookit是为无线手持设备（MDIP）定制的简易开发工具包。如果用户需要更强的IDE开发环境，那么请选用Forte for Java CE。目前SUN公司提供的开发工具中暂时还没有388的模拟器。 Java 2 SDK 1.3是必备的，它提供开发、测试和运行Java程序的平台 本人推荐jcreator. 5 Jcreater+MotoJ2SDK的配置与使用心得 假设安装路径如下： JCreator D:Program FilesXinox SoftwareJCreator LE motoj2sdk D:Motoj2sdk JDK D:jdk1.3.1 注意：要先击活模拟环境，运行D:MotoJ2SDKgenericscriptsrunConstructor.bat 选择手机型号，选择语言，选择normal， 再创建。 启动Jcreater之后我的配置如下： 第一步 选择 Configure-Options-JDK Profiles 注意：一定新建 profile and select “D:jdk1.3.1” 将名字改为“J2ME 388” Add classes path “D:Motoj2sdklib” Add documentation path “D:Motoj2sdkdocs” 分别将后加的两行移到最上方. 第二步 选择 Configure-Options-JDK Tools 选择Complier 选中 and edit it. 将 parameters 变为 -O -bootclasspath D:/motoj2sdk/lib $JavaFiles 第三步 选择 Configure-Options-Tools 点击“New”选择 DOS command 名字为“Preverifier” 将 arguments 换为 d:Motoj2sdkbinpreverifier.exe -classpath d:Motoj2sdklib -d . . 将 initial directory 变为 “$PrjDir” 第四步 按上面的方法在New一个 DOS command 名字：“Run Emulator” 将 arguments 换成 “java -Djava.library.path=d:/MotoJ2SDK/lib -classpath d:/MotoJ2SDK/bin/Emulator.jar;d:/MotoJ2SDK/ConfigTool.jar com.mot.tools.j2me.emulator.Emulator -classpath$PrjDir;d:/MotoJ2SDK/lib -deviceFile d:/MotoJ2SDK/bin/resources/ps javax.microedition.midlet.AppManager $CurClass -JSA 1 1” 将 initial directory 换成 “d:Motoj2sdkbin” 第五步 New DOS command “Create Jar” Change arguments to “$JavaHomebinjar.exe cvfM $PrjName.jar META-INFMANIFEST.MF *.CLASS *.png” Change initial directory to “$PrjDir” NOTE: You must add META-INFMANIFEST.MF in the project NOTE: You must change the directory “com/mot/project/*.CLASS” when you create your project. NOTE: If you have resource files, you should also add these files into jar file, 1 folder is not necessary. ok!编辑工具配置完毕！ 新建一个工程选择Empty Project 再取一个名字 比如：test 则jcreater自动在你的工作目录中生成目录test 再new一个file选择java File 写好你的原代码，保存 如：test.java 在Project中 选add file 然后选中你刚才的test.java 注意：不要有package ; 编译tools中的Preverifier进行预先审核tools中的Run Emulator进行模拟 test.java 的例子：功能是捕捉键盘输入的ascII吗。 import javax.microedition.lcdui.*; import javax.microedition.midlet.*; public class test extends MIDlet implements CommandListener /* * The screen for this MIDlet */ private KeyEventsDemoCanvas myCanvas; /* * Reference to current Display */ private Display myDisplay; /* * Command to make sure soft key is not a key event */ private Command okCommand = new Command(OK, Command.OK, 1); test() myDisplay = Display.getDisplay(this);

try g.drawString(Action: + getGameAction(lastKey), 0, 2 * g.getFont().getHeight(), Graphics.TOP | Graphics.LEFT); g.drawString(Key Name: + getKeyName(lastKey), 0, 3 * g.getFont().getHeight(), Graphics.TOP | Graphics.LEFT); catch (Exception e) / ignore since alphabet keys will throw this exception /* * Handle key press */ public void keyPressed(int keyCode) lastKey = keyCode; repaint(); /* * Demonstrate keyRepeated events */ public void keyRepeated(int keyCode) System.out.println(Key repeated + keyCode); 6怎么在主类中响应按钮消息，这个对于切换显示很有帮助。 /文件名 LWTDemoMIDlet.java import com.motorola.lwt.*; import javax.microedition.lcdui.*; import javax.microedition.midlet.*; public class LWTDemoMIDlet extends MIDlet implements CommandListener class ButtonScreen extends ComponentScreen public ButtonScreen() / Add a button to the screen Button b1 = new Button(b);

add(b1); / Add another button to the screen Button b2 = new Button(点我就行了) public void componentActuated() Show(); ; / Extend the right edge to the right edge of the screen b2.setRightEdge(Component.WIDTH, 220); b2.setBottomEdge(Component.HEIGHT, b2.getPreferredHeight() * 2); add(b2); Command next = new Command(Next, Command.OK, 1); Command prev = new Command(Previous, Command.BACK, 1); addCommand(next); addCommand(prev); ; ButtonScreen screens = new ButtonScreen(); public LWTDemoMIDlet() screens.setCommandListener(this); protected void startApp() throws MIDletStateChangeException Display.getDisplay(this).setCurrent(screens);
