copied!<p>I think that a Timer would work nicely for you. Perhaps something like this, where you cancel the timer and start a new timer every time you detect motion:</p> <p>define your timer in your activity (and make sure you cancel it when you leave the activity)</p> <pre><code>Timer lastTouchedTimer = null; </code></pre> <p>Then change your onSensorChanged like this:</p> <pre><code> public void onSensorChanged(SensorEvent event) { float x = event.values[0]; float y = event.values[1]; if(x > -0.1 && x < 0.1 && y > -0.1 && y < 0.1) { if (lastTouchedTimer == null) { lastTouchedTimer = new Timer(); } else lastTouchedTimer.cancel(); } lastTouchedTimer.schedule(new TimerTask() { @Override public void run() { try { AssetFileDescriptor afd = getAssets().openFd("beep.wav"); mMediaplayer = new MediaPlayer(); mMediaplayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength()); afd.close(); mMediaplayer.prepare(); mMediaplayer.start(); mMediaplayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { public void onCompletion(MediaPlayer mp) { //mp.setLooping(false); mp.stop(); mp.release(); } }); } catch(Exception e) { e.printStackTrace(); } } }, 5000); } } </code></pre> <p>Here is an activity, which I use in a sample activity.</p> <pre><code>package com.example.test; import android.app.Activity; import android.content.res.AssetFileDescriptor; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.media.MediaPlayer; import android.os.Bundle; import java.util.Timer; import java.util.TimerTask; public class MyActivity extends Activity { Timer lastTouchedTimer; MediaPlayer mMediaplayer; /** * Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); SensorEventListener newListener = new SensorEventListener() { @Override public void onSensorChanged(SensorEvent sensorEvent) { float x = sensorEvent.values[0]; float y = sensorEvent.values[1]; if(x > -0.1 && x < 0.1 && y > -0.1 && y < 0.1) { if (lastTouchedTimer == null) { lastTouchedTimer = new Timer(); } else lastTouchedTimer.cancel(); } lastTouchedTimer.schedule(new TimerTask() { @Override public void run() { try { AssetFileDescriptor afd = getAssets().openFd("beep.wav"); mMediaplayer = new MediaPlayer(); mMediaplayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength()); afd.close(); mMediaplayer.prepare(); mMediaplayer.start(); mMediaplayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { public void onCompletion(MediaPlayer mp) { //mp.setLooping(false); mp.stop(); mp.release(); } }); } catch(Exception e) { e.printStackTrace(); } } }, 5000); } @Override public void onAccuracyChanged(Sensor sensor, int i) { //To change body of implemented methods use File | Settings | File Templates. } }; } } </code></pre> <p>It uses a very simple xml file:</p> <pre><code><?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Heallo World, MyActivity" /> </LinearLayout> </code></pre>
