黑莓中的AutoCompleteField 可能最适合智能搜索。它从 BB5.0 及更高版本可用。它提供了一个文本字段，并按照您在文本框中输入的内容过滤数据和列表。 这是代码示例

BasicFilteredList filterList = new BasicFilteredList();
        String[] address = { "T 115 Centro Galleria Shopping Centre, Cnr Old Collier and Walters Road Morley WA 1522", 
                "784 SEAVIEW POINT POINT COOK VIC 2674",
                "Lot 1498 Yarraman Road Wyndham Vale VIC 3795", 
                "784 3506 Witchmount Close Hillside VIC 4055",
                "6 Paas Place Williamstown VIC 4233", 
                "Lot 99 14 James Close Sunbury VIC 4502", 
                "1 Charlotte Street Clayton South VIC 4779" };

        filterList.addDataSet(1, address, "days", BasicFilteredList.COMPARISON_IGNORE_CASE);

        CustomAutoCompleteTextField autoCompleteField = new CustomAutoCompleteTextField(filterList, AutoCompleteField.LIST_EXPAND_ON_HIGHLIGHT)

        {

            public void onSelect(Object selection, int SELECT_TRACKWHEEL_CLICK) {
                 ListField _list = getListField();

             }

            //ListField _list = this.getListField();
            public void fieldChanged(Field field, int context){

            }
        };
        add(autoCompleteField);
