 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; 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();  }  }

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