copied!<p>From the code point of view, you need to implement the SensorListener:</p> <pre><code>public class ShakeActivity extends Activity implements SensorListener </code></pre> <p>You will need to acquire a SensorManager:</p> <pre><code>sensorMgr = (SensorManager) getSystemService(SENSOR_SERVICE); </code></pre> <p>And register this sensor with desired flags:</p> <pre><code>sensorMgr.registerListener(this, SensorManager.SENSOR_ACCELEROMETER, SensorManager.SENSOR_DELAY_GAME); </code></pre> <p>In your onSensorChange() method, you determine whether it’s a shake or not:</p> <pre><code>public void onSensorChanged(int sensor, float[] values) { if (sensor == SensorManager.SENSOR_ACCELEROMETER) { long curTime = System.currentTimeMillis(); // only allow one update every 100ms. if ((curTime - lastUpdate) > 100) { long diffTime = (curTime - lastUpdate); lastUpdate = curTime; x = values[SensorManager.DATA_X]; y = values[SensorManager.DATA_Y]; z = values[SensorManager.DATA_Z]; float speed = Math.abs(x+y+z - last_x - last_y - last_z) / diffTime * 10000; if (speed > SHAKE_THRESHOLD) { Log.d("sensor", "shake detected w/ speed: " + speed); Toast.makeText(this, "shake detected w/ speed: " + speed, Toast.LENGTH_SHORT).show(); } last_x = x; last_y = y; last_z = z; } } } </code></pre> <p>The shake threshold is defined as:</p> <pre><code>private static final int SHAKE_THRESHOLD = 800; </code></pre> <p>There are some other methods too, to detect shake motion. look at this <a href="http://www.codeshogun.com/blog/2009/04/17/how-to-detect-shake-motion-in-android-part-i/" rel="noreferrer">link.</a>(If that link does not work or link is dead, <a href="http://web.archive.org/web/20100324212856/http://www.codeshogun.com/blog/2009/04/17/how-to-detect-shake-motion-in-android-part-i/" rel="noreferrer">look at this web archive</a>.).</p> <p>Have a look at this <a href="http://android.hlidskialf.com/blog/code/android-shake-detection-listener" rel="noreferrer">example</a> for android shake detect listener. </p> <p><strong>Note:</strong> <code>SensorListener</code> is deprecated. we can use <code>SensorEventListener</code> instead. <a href="http://jasonmcreynolds.com/?p=388" rel="noreferrer">Here is a quick example using SensorEventListener.</a></p> <p>Thanks.</p>
