blackberry - 如何在 Blackberry AutoCompleteField 中将所选项目作为字符串获取？

Question

如何在使用 Blackberry 自动完成字段时将所选项目作为字符串获取。我目前能够获得选定的索引。我正在重写 AutoCompleteField 类中的 onSelect 方法，如

中所述

Autocomplete Class Reference API JDE 5.0

下面的代码片段-

AutoCompleteField autoCompleteField = new AutoCompleteField(filterList)
{
     public void onSelect(Object selection, int SELECT_TRACKWHEEL_CLICK) {
         ListField _list = getListField();
         if (_list.getSelectedIndex() > -1) {
             Dialog.alert("You selected: "+_list.getSelectedIndex());
             // get text selected by user and do something...
         }
     }
};

AutoCompleteField#onSelect(Object, int) 的默认实现将 AutoCompleteField 对象的 AutoCompleteFieldEditField 文本设置为 select 参数。所以你可以用这种方式查询字符串。这是我的意思的一个片段:

AutoCompleteField autoCompleteField = new AutoCompleteField(filterList)
{
     public void onSelect(Object selection, int type) {
         super.onSelect(selection, type);
         if(selection != null) {
             String selectionAsString = getEditField().getText();
             // Do whatever else you need to do with the String.
         }
     }
};
