            }
             return false;
    }

    //停止播放铃声
    public void stopRing()
    {
             mediaPlayer.stop();
    }

    //震动
    public void vibrate(int ms)//输入震动毫秒数
   {
             Vibrator vibrator = (Vibrator)getSystemService(VIBRATOR_SERVICE);

             vibrator.vibrate(ms);     
    }

使用时要注意在AndroidManifest.xml中添加权限

 发送短信权限

 <uses-permission android:name="android.permission.SEND_SMS"/>

震动权限
 <uses-permission android:name="android.permission.VIBRATE"/>

具体实现可以封装在Service中提供调用，如何实现请看android Service调用，传参。
