本实例主要使用了android的重力感应功能并配合动画效果实现，主要代码如下：

第一：ShakeActivity主类：

 第二：一个检测手机摇晃的监听器类ShakeListener ，代码如下：

package com.android.shake; 
import android.content.Context; 
import android.hardware.Sensor; 
import android.hardware.SensorEvent; 
import android.hardware.SensorEventListener; 
import android.hardware.SensorManager; 
import android.util.Log; 
/** 
 * 一个检测手机摇晃的监听器 
 */ 
public class ShakeListener implements SensorEventListener { 
 // 速度阈值，当摇晃速度达到这值后产生作用 
 private static final int SPEED_SHRESHOLD = 2000; 
 // 两次检测的时间间隔 
 private static final int UPTATE_INTERVAL_TIME = 70; 
 // 传感器管理器 
 private SensorManager sensorManager; 
 // 传感器 
 private Sensor sensor; 
 // 重力感应监听器 
 private OnShakeListener onShakeListener; 
 // 上下文 
 private Context mContext; 
 // 手机上一个位置时重力感应坐标 
 private float lastX; 
 private float lastY; 
 private float lastZ; 
 // 上次检测时间 
 private long lastUpdateTime; 
 // 构造器 
 public ShakeListener(Context c) { 
 // 获得监听对象 
 mContext = c; 
 start(); 
 } 
 // 开始 
 public void start() { 
 // 获得传感器管理器 
 sensorManager = (SensorManager) mContext 
 .getSystemService(Context.SENSOR_SERVICE); 
 if (sensorManager != null) { 
 // 获得重力传感器 
 sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); 
 } 
 // 注册 
 if (sensor != null) { 
 sensorManager.registerListener(this, sensor, 
  SensorManager.SENSOR_DELAY_GAME); 
 } 
 } 
 // 停止检测 
 public void stop() { 
 sensorManager.unregisterListener(this); 
 } 
 // 设置重力感应监听器 
 public void setOnShakeListener(OnShakeListener listener) { 
 onShakeListener = listener; 
 } 
 // 重力感应器感应获得变化数据 
 public void onSensorChanged(SensorEvent event) { 
 // 现在检测时间 
 long currentUpdateTime = System.currentTimeMillis(); 
 // 两次检测的时间间隔 
 long timeInterval = currentUpdateTime - lastUpdateTime; 
 // 判断是否达到了检测时间间隔 
 if (timeInterval < UPTATE_INTERVAL_TIME) 
 return; 
 // 现在的时间变成last时间 
 lastUpdateTime = currentUpdateTime; 
 // 获得x,y,z坐标 
 float x = event.values[0]; 
 float y = event.values[1]; 
 float z = event.values[2]; 
 // 获得x,y,z的变化值 
 float deltaX = x - lastX; 
 float deltaY = y - lastY; 
 float deltaZ = z - lastZ; 
 // 将现在的坐标变成last坐标 
 lastX = x; 
 lastY = y; 
 lastZ = z; 
 double speed = Math.sqrt(deltaX * deltaX + deltaY * deltaY + deltaZ 
 * deltaZ) 
 / timeInterval * 10000; 
 // 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 
 public interface OnShakeListener { 
 public void onShake(); 
 } 
}

代码：

package com.android.shake; 
import android.content.Context; 
import android.hardware.Sensor; 
import android.hardware.SensorEvent; 
import android.hardware.SensorEventListener; 
import android.hardware.SensorManager;

 // 传感器管理器 
 private SensorManager sensorManager; 
 // 传感器 
 private Sensor sensor; 
 // 重力感应监听器 
 private OnShakeListener onShakeListener; 
 // 上下文 
 private Context mContext; 
 // 手机上一个位置时重力感应坐标 
 private float lastX; 
 private float lastY; 
 private float lastZ; 
 // 上次检测时间 
 private long lastUpdateTime; 
 // 构造器 
 public ShakeListener(Context c) { 
 // 获得监听对象

 start(); 
 } 
 // 开始 
 public void start() { 
 // 获得传感器管理器 
 sensorManager = (SensorManager) mContext 
 .getSystemService(Context.SENSOR_SERVICE); 
 if (sensorManager != null) { 
 // 获得重力传感器 
 sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); 
 } 
 // 注册 
 if (sensor != null) { 
 sensorManager.registerListener(this, sensor, 
  SensorManager.SENSOR_DELAY_GAME); 
 } 
 } 
 // 停止检测 
 public void stop() { 
 sensorManager.unregisterListener(this); 
 } 
 // 设置重力感应监听器 
 public void setOnShakeListener(OnShakeListener listener) { 
 onShakeListener = listener; 
 } 
 // 重力感应器感应获得变化数据 
 public void onSensorChanged(SensorEvent event) { 
 // 现在检测时间 
 long currentUpdateTime = System.currentTimeMillis(); 
 // 两次检测的时间间隔 
 long timeInterval = currentUpdateTime - lastUpdateTime; 
 // 判断是否达到了检测时间间隔 
 if (timeInterval < UPTATE_INTERVAL_TIME) 
 return; 
 // 现在的时间变成last时间 
 lastUpdateTime = currentUpdateTime; 
 // 获得x,y,z坐标 
 float x = event.values[0]; 
 float y = event.values[1]; 
 float z = event.values[2]; 
 // 获得x,y,z的变化值 
 float deltaX = x - lastX; 
 float deltaY = y - lastY; 
 float deltaZ = z - lastZ; 
 // 将现在的坐标变成last坐标 
 lastX = x; 
 lastY = y; 
 lastZ = z; 
 double speed = Math.sqrt(deltaX * deltaX + deltaY * deltaY + deltaZ 
 * deltaZ) 
 / timeInterval * 10000; 
 // 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 
 public interface OnShakeListener { 
 public void onShake(); 
 } 
}

 第三：必须在AndroidManifest.xml中添加权限，否侧摇动时不能监听

<uses-permission android:name="android.hardware.sensor.accelerometer"/>
