我写了一个检测垂直和水平震动并显示Toast的小例子。

        mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        mSensorManager.registerListener(this, mAccelerometer , SensorManager.SENSOR_DELAY_NORMAL);
    }

    }

我已经尝试了几种实现，但我想分享一下我自己的实现。 它以g力为单位进行阈值计算。这让我们更容易理解发生了什么，同时也设置了一个好的阈值。

它只是记录G力的增加，如果超过阈值就触发侦听器。它不使用任何方向阈值，因为如果你只是想记录一个好的震动，你真的不需要这个。

当然，您需要在Activity中对这个侦听器进行标准的注册和un -注册。

此外，为了检查您需要的阈值，我推荐以下应用程序(我没有以任何方式连接到该应用程序)

    public class UmitoShakeEventListener implements SensorEventListener {

    /**
     * The gforce that is necessary to register as shake. (Must include 1G
     * gravity)
     */
    private final float shakeThresholdInGForce = 2.25F;

    private final float gravityEarth = SensorManager.GRAVITY_EARTH;

    private OnShakeListener listener;

    public void setOnShakeListener(OnShakeListener listener) {
        this.listener = listener;
    }

    public interface OnShakeListener {
        public void onShake();
    }

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {
        // ignore

    }

    @Override
    public void onSensorChanged(SensorEvent event) {

        if (listener != null) {
            float x = event.values[0];
            float y = event.values[1];
            float z = event.values[2];

            float gX = x / gravityEarth;
            float gY = y / gravityEarth;
            float gZ = z / gravityEarth;

            //G-Force will be 1 when there is no movement. (gravity)
            float gForce = FloatMath.sqrt(gX * gX + gY * gY + gZ * gZ); 



            if (gForce > shakeThresholdInGForce) {
                listener.onShake();

            }
        }

    }

}

你可能想试试开源tinybus。有了它，震动检测就像这样简单。

public class MainActivity extends Activity {

    private Bus mBus;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ...

        // Create a bus and attach it to activity
        mBus = TinyBus.from(this).wire(new ShakeEventWire());
    }

    @Subscribe
    public void onShakeEvent(ShakeEvent event) {
        Toast.makeText(this, "Device has been shaken", 
                Toast.LENGTH_SHORT).show();
    }

    @Override
    protected void onStart() {
        super.onStart();
        mBus.register(this);
    }

    @Override
    protected void onStop() {
        mBus.unregister(this);
        super.onStop();
    }
}

它采用地震仪进行振动检测。
