首先介绍一下 微信摇一摇实现原理
利用加速感应，因为一般的android手机都支持此感应，应用很普遍，然后利用动画实现图片上下分开的效果。当然为了实用在图片上下分开的同时可以加上一些音乐和震动，
播放音乐
MediaPlayer player;
player = MediaPlayer.create(this, R.raw.awe);
player.setLooping(false);
player.start();
添加震动，，当然震动是系统调用，需要权限 <uses-permission android:name="android.permission.VIBRATE" />
Vibrator mVibrator;
mVibrator = (Vibrator)getApplication().getSystemService(VIBRATOR_SERVICE);
mVibrator.vibrate( new long[]{500,200,500,200}, -1); //第一个｛｝里面是节奏数组， 第二个参数是重复次数，-1为不重复，非-1俄日从pattern的指定下标开始重复
记得用完使用 mVibrator.cancel(); 消除
现在开始实现功能
实现 android加速感应的监听事件接口 SensorEventListener
实现该接口 需要覆写，eclipse自动提示
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
// TODO Auto-generated method stub
}
@Override
public void onSensorChanged(SensorEvent event) {
// TODO Auto-generated method stub
}

// 判断是否达到了检测时间间隔

// 现在的时间变成last时间

// 获得x,y,z坐标

Log.v("thelog", "===========log===================");
// 达到速度阀值，发出提示
if (speed >= SPEED_SHRESHOLD) {
onShakeListener.onShake();
}
}
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
// 摇晃监听接口
