android手动调用振动器(Vibrator)

Vibrator vv=(Vibrator) getApplication().getSystemService(Service.VIBRATOR_SERVICE); vv.vibrate(500);//震半秒钟 vv.vibrate(new long[]{10, 100, 20, 200}, -1); 关于vv.vibrate(new long[]{10, 100, 20, 200}, -1); 参数1：表示停10ms, 震100ms, 停20ms，震200ms 参数2：-1 表示不重复，非-1表示从指定的下标开始重复震动！ 注意 ：如第二个参数是0, 则一圈一圈的循环震动下去了；如果是2，这第一遍震动后，从"20”这个参数开始再循环震动！ 一般用vv.vibrate(500);//震半秒钟就行了 vv.cancel();//停止震动,基本只有在循环震动时才用得到这个 本文转自java豆子博客园博客，原文链接：http://www.cnblogs.com/error404/archive/2011/09/21/2184132.html，如需转载请自行联系原作者

本地windows跑Scala程序调用Spark

应用场景 spark是用scala写的一种极其强悍的计算工具，spark内存计算，提供了图计算，流式计算，机器学习，即时查询等十分方便的工具，所以利用scala来进行spark编程是十分必要的，下面简单书写一个spark连接mysql读取信息的例子。 操作流程 按照windows搭建Scala开发环境博文，搭建scala开发环境，实际已经将Spark环境部署完成了，所以直接可以用scala语言写一些spark相关的程序！ package epoint.com.cn.test001 import org.apache.spark.sql.SQLContext import org.apache.spark.SparkConf import org.apache.spark.SparkContext import org.apache.spark.rdd.RDD object SparkConnMysql { def main(args: Array[String]) { println("Hello, world!") val conf = new SparkConf() conf.setAppName("wow,my first spark app") conf.setMaster("local") val sc = new SparkContext(conf) val sqlContext = new SQLContext(sc) val url = "jdbc:mysql://192.168.114.67:3306/user" val table = "user" val reader = sqlContext.read.format("jdbc") reader.option("url", url) reader.option("dbtable", table) reader.option("driver", "com.mysql.jdbc.Driver") reader.option("user", "root") reader.option("password", "11111") val df = reader.load() df.show() } } 运行结果： Hello, world!
