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;
/**

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 final int KEY_RSOFT = -7;
public static final int KEY_CLEAR = -8;
public static final int KEY_SEND = -10;

}
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 |
