public void onAccuracyChanged(Sensor sensor, int accuracy) {}
}

这里还有另一个实现，它是基于这里的一些技巧以及来自Android开发人员网站的代码。

MainActivity.java

public class MainActivity extends Activity {

    private ShakeDetector mShakeDetector;
    private SensorManager mSensorManager;
    private Sensor mAccelerometer;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // ShakeDetector initialization
        mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
        mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        mShakeDetector = new ShakeDetector(new OnShakeListener() {
            @Override
            public void onShake() {
                // Do stuff!
            }
        });
    }

    @Override
    protected void onResume() {
        super.onResume();
        mSensorManager.registerListener(mShakeDetector, mAccelerometer, SensorManager.SENSOR_DELAY_UI);
    }

    @Override
    protected void onPause() {
        mSensorManager.unregisterListener(mShakeDetector);
        super.onPause();
    }   
}

ShakeDetector.java

        float maxLinearAcceleration = getMaxCurrentLinearAcceleration();

        // Check if the acceleration is greater than our minimum threshold

    @Override

    private void setCurrentAcceleration(SensorEvent event) {
        /*

        // alpha is calculated as t / (t + dT)

        final float alpha = 0.8f;

        // Gravity components of x, y, and z acceleration
        mGravity[X] = alpha * mGravity[X] + (1 - alpha) * event.values[X];

        mGravity[Z] = alpha * mGravity[Z] + (1 - alpha) * event.values[Z];

        // Linear acceleration along the x, y, and z axes (gravity effects removed)

    private float getMaxCurrentLinearAcceleration() {

        float maxLinearAcceleration = mLinearAcceleration[X];

        // Check if the y value is greater
        if (mLinearAcceleration[Y] > maxLinearAcceleration) {
            maxLinearAcceleration = mLinearAcceleration[Y];
        }

        // Check if the z value is greater
        if (mLinearAcceleration[Z] > maxLinearAcceleration) {
            maxLinearAcceleration = mLinearAcceleration[Z];
        }

        // Return the greatest value
        return maxLinearAcceleration;
    }

    private void resetShakeDetection() {
        startTime = 0;
        moveCount = 0;

    // (I'd normally put this definition in it's own .java file)
    public interface OnShakeListener {
        public void onShake();

}

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();

            }
        }

    }

}

我写了一个检测垂直和水平震动并显示Toast的小例子。

public class Accelerometerka2Activity extends Activity implements SensorEventListener { 
    private float mLastX, mLastY, mLastZ;
    private boolean mInitialized;
    private SensorManager mSensorManager;
    private Sensor mAccelerometer;
    private final float NOISE = (float) 8.0;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mInitialized = false;
        mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
        mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        mSensorManager.registerListener(this, mAccelerometer , SensorManager.SENSOR_DELAY_NORMAL);
    }

    protected void onResume() {
        super.onResume();
        mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
    }

    protected void onPause() {
        super.onPause();
        mSensorManager.unregisterListener(this);
    }


    public void onAccuracyChanged(Sensor sensor, int accuracy) {
        // can be safely ignored for this demo
    }


    public void onSensorChanged(SensorEvent event) {
        float x = event.values[0];
        float y = event.values[1];
        float z = event.values[2];
        if (!mInitialized) {
            mLastX = x;
            mLastY = y;
            mLastZ = z;
            mInitialized = true;
        } else {
            float deltaX = Math.abs(mLastX - x);
            float deltaY = Math.abs(mLastY - y);
            float deltaZ = Math.abs(mLastZ - z);
            if (deltaX < NOISE) deltaX = (float)0.0;
            if (deltaY < NOISE) deltaY = (float)0.0;
            if (deltaZ < NOISE) deltaZ = (float)0.0;
            mLastX = x;
            mLastY = y;
            mLastZ = z;
            if (deltaX > deltaY) {
                Toast.makeText(getBaseContext(), "Horizental", Toast.LENGTH_SHORT).show();
            } else if (deltaY > deltaX) {
                Toast.makeText(getBaseContext(), "Vertical", Toast.LENGTH_SHORT).show();
            }
        }
    }
}

你可以用地震法。这里可以找到一个例子。
