}

把这个添加到你的活动中:

  private SensorManager mSensorManager;

  private ShakeEventListener mSensorListener;

...

在onCreate()中添加:

    mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
    mSensorListener = new ShakeEventListener();   

    mSensorListener.setOnShakeListener(new ShakeEventListener.OnShakeListener() {

      public void onShake() {
        Toast.makeText(KPBActivityImpl.this, "Shake!", Toast.LENGTH_SHORT).show();
      }
    });

and:

@Override
  protected void onResume() {
    super.onResume();
    mSensorManager.registerListener(mSensorListener,
        mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
        SensorManager.SENSOR_DELAY_UI);
  }

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

在您的活动中，添加以下代码，使其检测震动事件:

ShakeEventListener(this, sensorManager){
    // onShake logic
}

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。

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();
            }
        }
    }
}
