如何获得所选择的项目为String在黑莓AutoCompleteField？

问题描述

如何使用黑莓手机自动完成现场时获得所选项目的字符串。我现在能拿到选定的索引。我覆盖在AutoCompleteField类中的方法ONSELECT截至

解释

自动完成类参考API JDE 5.0

code以下片段 -

  AutoCompleteField autoCompleteField =新AutoCompleteField（filterList）
{
     公共无效ONSELECT（对象选择，诠释SELECT_TRACKWHEEL_CLICK）{
         ListField _list = getListField（）;
         如果（_list.getSelectedIndex（）-1个）{
             Dialog.alert（您选择：+ _list.getSelectedIndex（））;
             //获取用户选定的文本，做一些事情...
         }
     }
};
 

解决方案

AutoCompleteField＃ONSELECT（对象，INT）的默认实现将AutoCompleteField对象的AutoCompleteFieldEditField到选择参数的文本。所以，你可以查询字符串的方式。下面是我的意思的代码段：

  AutoCompleteField autoCompleteField =新AutoCompleteField（filterList）
{
     公共无效ONSELECT（对象选择，整型）{
         super.onSelect（选择型）;
         如果（选择！= NULL）{
             字符串selectionAsString = getEditField（）的getText（）。
             //你需要用字符串做其他。
         }
     }
};
 

How to get the selected Item as string when using a Blackberry AutoComplete Field. I am able to get the selected index currently. I am Overriding the onSelect method in the AutoCompleteField class as explained at

Autocomplete Class Reference API JDE 5.0

Code Snippet below -

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...
         }
     }
};

解决方案

The default implementation of AutoCompleteField#onSelect(Object, int) sets the text of the AutoCompleteField object's AutoCompleteFieldEditField to the select parameter. So you could query for the String that way. Here's a snippet of what I mean:

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.
         }
     }
};
