Answer 1

같은 세 가지 editfields를 만듭니다. 그러나 너비 &의 너비를 VerticalFieldManager에 지정해야합니다. 그렇지 않으면 너비가 기본적으로 적용됩니다.

VerticalFieldManager vfm_city = new VerticalFieldManager() { 
    protected void sublayout(int maxWidth, int maxHeight) { 
     super.sublayout(Display.getwidth()/3,30); 
     setExtent(Display.getwidth()/3,30); 
    } 
}; 

은 국가 & 도시 vfm에서이 작업을 수행하고 hfm에 추가하려고합니다.
