现在有不少的应用开始实现了摇一摇功能，今天就把摇一摇的实现过程做一下记录。
用到知识点
1.加速度传感器
2.补间动画
3.手机震动 (Vibrator)
4.较短 声音/音效 的播放 (SoundPool)
首先布局文件

// 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 OnShakeListenerCallBack 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 context) { // 获得监听对象 mContext = context; start(); } /**开始重力传感器的检测*/ 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); } /**重力感应器感应获得变化数据*/ @Override 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(); } } @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { } /**摇晃监听接口*/ public interface OnShakeListenerCallBack { public void onShake(); } /**设置重力感应监听器*/ public void setOnShakeListener(OnShakeListenerCallBack listener) { onShakeListener = listener; } } 首先获取SensorManager，进而获取到加速度传感器，再设置监听器。然后在监听中根据传感器数值的变化，根据需要做响应的处理。当达到要求时进行回调，进而实现摇一摇后响应的逻辑(音效、动画等)。 摇一摇完成后动画 /** 摇一摇手掌上部分动画 */ public AnimationSet getUpAnim(){ AnimationSet animationSet = new AnimationSet(true); TranslateAnimation translateAnimation0 = new TranslateAnimation(Animation.RELATIVE_TO_SELF,0,Animation.RELATIVE_TO_SELF,0,Animation.RELATIVE_TO_SELF,0,Animation.RELATIVE_TO_SELF,-0.8f); translateAnimation0.setDuration(OPEN_TIME);

} } @Override public void onAnimationRepeat(Animation animation) { } }); return translateAnimation; } /** 隐藏摇出结果动画 */ public Animation getReusltGoneAnim(){ TranslateAnimation translateAnimation = new TranslateAnimation(Animation.RELATIVE_TO_SELF,0,Animation.RELATIVE_TO_SELF,0,Animation.RELATIVE_TO_SELF,0,Animation.RELATIVE_TO_SELF,3); translateAnimation.setDuration(OPEN_TIME); translateAnimation.setAnimationListener(new Animation.AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { if (mDoAnimationListener != null) { mDoAnimationListener.onAnimEnd(SHAKE_RESULT_GONE_CODE);

} } @Override public void onAnimationEnd(Animation animation) { } @Override public void onAnimationRepeat(Animation animation) { } }; /**手掌图合上动画监听*/ public Animation.AnimationListener closeAnimationListener = new Animation.AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { //动画结束时回调 if (mDoAnimationListener != null) { mDoAnimationListener.onAnimEnd(COLSE_ANIM_CODE); } } @Override public void onAnimationRepeat(Animation animation) { } }; public interface DoAnimationListener{ void onAnimStart(int code); void onAnimEnd(int code); } 震动 震动首先要加权限 震动代码 Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE); vibrator.vibrate(500); 接下来就是播放音效了 public class Sound { private static Sound mInstance; private SoundPool mSoundPool;//音效池 private HashMap public static Sound getInstance() { if (mInstance == null) { mInstance = new Sound(); } return mInstance; } /**初始化音效池---向音效池添加音效*/ public void initPool(final Context context){ mSoundPoolMap = new HashMap<>(); mSoundPool = new SoundPool(3, AudioManager.STREAM_ALARM,1); if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) { AudioAttributes audioAttributes = null; audioAttributes = new AudioAttributes.Builder() .setUsage(AudioAttributes.USAGE_ALARM) .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC) .build(); mSoundPool = new SoundPool.Builder() .setMaxStreams(3) .setAudioAttributes(audioAttributes) .build(); } else { // 5.0 以前 mSoundPool = new SoundPool(3, AudioManager.STREAM_ALARM, 0); // 创建SoundPool } new Thread(new Runnable() { @Override public void run() { mSoundPoolMap.put(0,mSoundPool.load(context.getResources().openRawResourceFd(R.raw.shake_sound_male),1)); mSoundPoolMap.put(1,mSoundPool.load(context.getResources().openRawResourceFd(R.raw.shake_match),1)); mSoundPoolMap.put(2,mSoundPool.load(context.getResources().openRawResourceFd(R.raw.shake_nomatch),1)); } }).start(); } /** 播放摇一摇开始声音 */ public void playStartSound(){ try { mSoundPool.play(mSoundPoolMap.get(0),1,1,0,0,1.3f); } catch (Exception e) { e.printStackTrace(); } } /** 播放摇一摇结束声音 */ public void playEndSound(){ try { mSoundPool.play(mSoundPoolMap.get(1),1,1,0,0,1.0f);
