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