Shake function

1. Get Sensor Management Classes

SensorManager sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);

2. Inherit the SensorEventListener interface and override sensor listening methods

@Override public void onSensorChanged(SensorEvent event) { /** * 1,Get the sensor type (shake if accelerometer) * 2,Judging its acceleration */ int type = event.sensor.getType(); if (type != Sensor.TYPE_ACCELEROMETER) { return; } long currentTime = System.currentTimeMillis(); long diffTime = currentTime - mLastUpdateTime; //UPDATE_INTERVAL=100 detection interval if (diffTime < UPDATE_INTERVAL) { return; } mLastUpdateTime = currentTime; float x = event.values[0]; float y = event.values[1]; float z = event.values[2]; //When mLastX, mLastY, mLastZ was last detected, the component of acceleration in the x, y, z direction was used to compare with the current acceleration. float deltaX = x - mLastX; float deltaY = y - mLastY; float deltaZ = z - mLastZ; mLastX = x; mLastY = y; mLastZ = z; float delta = (float) (Math.sqrt(deltaX * deltaX + deltaY * deltaY + deltaZ * deltaZ) / diffTime * 10000); // When the difference in acceleration is greater than the specified threshold, this is considered a shake if (delta > 500) { Message message = Message.obtain(); message.what = 1; mHandler.sendMessage(message); } } @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { }

3. Register listeners

if (sensorManager != null) { Sensor sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); if (sensor != null) { sensorManager.registerListener(listener, sensor, SensorManager.SENSOR_DELAY_NORMAL); } } // sensorManager.registerListener(listener,sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),SensorManager.SENSOR_DELAY_NORMAL);

4. Cancel the listener

sensorManager.unregisterListener(listener);

Add a shake effect

1. Initialize sound, add sound file
soundPool = new SoundPool(10, AudioManager.STREAM_SYSTEM, 5);//Use below 5.0 soundId = soundPool.load(context, R.raw.shake_sound, 1);

2. Play sound after shaking
soundPool.play(soundId, 1f, //Left Channel [0~1] 1f, //Right Channel [0~1] 1,//Play priority [0 means lowest priority] 0,//Number of cycles [0 for once, -1 for infinite times] 1);//Play speed 0 is normal speed [0~2]

Add a shake

1. Initialization Class
Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);

2. Add vibration after shaking
vibrator.vibrate(300);//300milliseconds

Note: Add permissions

<!--Shake the permissions you need-->
<uses-permission android:name="android.hardware.sensor.accelerometer" />
<!--Permissions required for vibration-->
<uses-permission android:name="android.permission.VIBRATE" />
