把调试结果粘出来我看下

不是错的,我师傅叫我在原有的代码上,改成动态生成

[kf156]

建议去看下API手册
ChoiceGroup的构造方法

[fy897578]

能不能帮我改一下啊,很急的

[kf156]

用这个构造
ChoiceGroup(String label, int choiceType, String[] stringElements, Image[] imageElements)

我是个刚学J2ME的菜鸟,动态生成太深,可以的话,希望你能帮我改一下.谢谢

...

就是把
movies = new ChoiceGroup("Select Movies You Like to See",Choice.MULTIPLE);
movies.append("Action", null);
movies.append("Romance", null);
movies.append("Comedy", null);
movies.append("Horror", null);

改成

//根据这String[]数组，动态创建
String[] stringElements={"Action", "Romance","Comedy","Horror"};
movies = new ChoiceGroup("Select Movies You Like to See", Choice.MULTIPLE, stringElements, null);
