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); 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); vibrator.vibrate(300);//300milliseconds<!--Shake the permissions you need-->
<uses-permission android:name="android.hardware.sensor.accelerometer" />
<!--Permissions required for vibration-->
<uses-permission android:name="android.permission.VIBRATE" />
