android Vibrator类介绍

**android手机中的震动由Vibrator实现。设置震动事件，需要知道其震动的时间长短、震动的周期等。**

**在android中，震动的时间一毫秒计算（1/1000秒），所以如果设置的时间值太小，会感觉不出来。**

**通过调用Vibrator的vibrate(long\[\] pattern, int repeat)方法实现。**

**前一个参数为设置震动的效果的数组，第二个参数为 -1表示只震动一次，为0则震动会一直持续。**

**Demo:**

            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            init();
            tog1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    			
    			@Override
