T628降价了,买了一个玩玩,这个“鸡鸡”支持JAVA扩展,所以第一时间去http://developer.sonyericsson.com/site/global/home/p_home.jsp下载了最新的SDK(FILE SIZE:42M),下载的时候要注意,SDK说明中应该指出支持T628,eclipse和eclipseme是早就下好的,下面就该安装了:
1、安装j2se 1.4.2,并配置path和classpath
2、安装semc_j2me_sdk_2_1_5.exe,装完后我没有做任何配置(包括环境变量配置)
3、解压缩eclipse,然后把eclipseme解压缩到eclipse的plugins目录中
4、然后就配置eclipseme(如图1)
5、创建一个jeme工程,File/New/Project.../J2ME/J2ME Midlet Suite
6、在工程中添加Midlet,File/New/Other../J2ME/J2ME Midlet
7、编写代码
8、在Navigator的工程上点右键,执行右键菜单里的J2ME/Create Package
9、用模拟器(图2)或通过蓝牙传到手机上执行
(图1)
(图2)
代码如下:

代码结束
提示:T628仅支持CLDC 1.0 和MIDP 1.0 ,在新建设工程时,平台选择Sony Ericsson J2ME SDK(WTK 1.0.4) Platform ,如果选择Sony Ericsson J2ME SDK(WTK 2.1) Platform 则,在模拟器上可以运行,但传到T628上会提示无效的应用程序。
