ANDROID 如何实现一键多值

请问 android下的硬键盘 ，现在要实现1键多值。比如在1秒钟内，按1下输出A，连按两下输出B，连按3下输出C。 现在是通过 onKeyDown，能够实现按1个键输入A

[解决办法]

Java code

    long clickTime;    Calendar cal;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        cal = Calendar.getInstance();        clickTime = cal.getTimeInMillis();                Button button = new Button(this);        button.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                long now =  Calendar.getInstance().getTimeInMillis();                System.out.println(now+","+clickTime);                if (now - clickTime <= 1000) {                    //自行处理                    System.out.println("1秒内");                }                clickTime=now;            }        });        setContentView(button);    }

给你说原理把 就是点击一下获取当前时间，再下一次点击的时候判断一下和前一次点击的时间相差多少秒，相差不足1s就变换。。。。如果相差大于1s就从第一个字母开始
