高仿微信摇一摇,动画效果为左右晃动

原文地址;http://blog.csdn.net/catoop/article/details/8051835,原博主实现了摇一摇

在这几天的学习中,添加了状态栏和摇晃完以后的动画,如图

                                               

学习到东西,发出来帮助更多的人,做一个有奉献精神的人

思路;

1.getSystemService(SENSOR_SERVICE)得到SensorManager ,有了它你就可以管理传感器了

2.getSystemService(VEBRATOR_SERVICE)得到手机振动的服务

3.initActionBar 设置手机状态栏的返回键

4.重力感应监听

5handler发送消息

6监听到以后 执行动画

 

代码如下
