我正在尝试从 Blackberry Calendar 获取事件。我试图显示同时发生的事件一个接一个

8:00 e1
8:00 e2

与本机日历一样

但是以下代码将输出显示为

8:00 e1 e2

在我的代码中，我在单个 vfm 中添加了 24 个 hfm。

int size1 = 2;
horizontalFieldManager_left22 = new  HorizontalFieldManager[size1];
for (int y = 0; y < size1; y++) {
horizontalFieldManager_left22[y] = new  HorizontalFieldManager() {
protected boolean navigationClick(int status, int time) {
Field field = getFieldWithFocus();
Vector data = getData(listEvent);
String  currentData = desc22.getText();
String  currentTime = time22.getText();
 if  (currentData != null && currentData != "") {
         UiApplication.getUiApplication().pushScreen(new EventScreen(data,currentData,currentTime));
            }
    return super.navigationClick(status, time);
        }

    protected boolean keyChar  (char key, int status, int time) {
    Field field = getFieldWithFocus();

     return
     super.keyChar(key, status, time);
          }
   };

   int size = eventVector7.size();
   LabelField[] labelField = new
   LabelField[size];
   for (int x = 0; x < eventVector7.size(); x++) {
   labelField[x] = new
   LabelField("", Field.FOCUSABLE);
   String data = (String)
   eventVector7.elementAt(x);
   labelField[x].setText(data);
  horizontalFieldManager_left22[y].add(time22);

  horizontalFieldManager_left22[y].add(min22);

  horizontalFieldManager_left22[y].add(new LabelField(" "));

  horizontalFieldManager_left22[y].add(labelField[x]);

        }

   }
 for (int z = 0; z < size1; z++) {
       vfm.add(horizontalFieldManager_left22 [z]);
       vfm.add(new SeparatorField());
      }
