请教大家如何用C#实现T9输入法的功能
T9输入法应该不用多说，传统的手机都是这样，用过的应该知道只要求设计数字输入模式和abc英文输入
举个例子，一般T9键盘的数字2键，按一下输入一个2，按两下输入两个2，以此类推
如果切换到abc英文输入模式，按一下屏幕显示a，如果连续按2下，屏幕先显示a，再变成b
如果不是连续按，而是按一下之后过一会儿再按一下，那第一个a保留，继续显示第二个a，并等待是否有连续按键，如果等待过程中按了其它键，那当前a保留，显示其它按键内容
我自己用Timer尝试了一下，但逻辑比较乱，理不过来
希望知道的大侠，不吝赐教 --------------------编程问答-------------------- 利用timer控件不合适吧
这个东西理清思路，应该很容易的。 --------------------编程问答-------------------- 朱建锋同学，我的人机交互实验作业是找不到答案的，要自己多动脑筋。记得你了，加油同学~回头发个邮件给我wanghui198218@yahoo.cn --------------------编程问答-------------------- 老师 - -不能随便透露个人信息的 --------------------编程问答-------------------- ASC码里面a加1就是b了，可以这样试试 --------------------编程问答-------------------- 朱建锋同学 我顶你一下 哈哈 --------------------编程问答-------------------- 这不是timer能判读的
应当是有逻辑调用的
独立的方法 --------------------编程问答--------------------
