AutoCompleteField 文字输入自动完成

BlackBerry SDK 5.0提供输入过滤，输入自动完成的功能。

BasicFilteredList - 创建过滤列表

AutoCompleteField - 创建输入自动完成Field

// 首先创建过滤列表

BasicFilteredList filterList = new BasicFilteredList();

 

// 自动完成内容
String[] days = {"Monday","Tuesday","Wednesday", "Thursday","Friday","Saturday","Sunday"};

// 设置过滤内容  

int uniqueID = 0;
filterList.addDataSet(uniqueID,days,"days",BasicFilteredList.COMPARISON_IGNORE_CASE);

// 创建输入自动完成功能， 设置自动完成标准

AutoCompleteField autoCompleteField = new AutoCompleteField(filterList);

add(autoCompleteField);
