copied!<p>There are a few things going on here (disclaimer, this is just how I'm used to using it, there may be a better way):</p> <ul> <li><p>You seem to be doing a lot more work per click than you need to. You're creating and adding a new <code>onClickListener</code> for every click <em>in the Activity's View, not the Button</em>. You only need to set the listener once, and for the Button rather than the overarching View; I tend to do that in the constructor of the Activity.</p></li> <li><p>Regarding your error, MediaPlayer works fine for me when the Context I pass it is the overriding Activity. When you pass <code>this</code>, it's passing the <code>onClickListener</code> you are creating, throwing off the MediaPlayer.</p></li> <li><p>Finally, to actually play the sound, you have to call <code>start()</code>.</p></li> </ul> <p>So for the constructor in the Activity, you can create the <code>MediaPlayer</code> once, find the Button, and attach an <code>onClickListener</code> that will play the sound from the MediaPlayer you've just created. It would look something like:</p> <pre><code>public class MyActivity extends Activity { public MyActivity(Bundle onSavedStateInstance) { // eliding some bookkeepping MediaPlayer mp = MediaPlayer.create(this, R.raw.mamacita_zero); Button zero = (Button)this.findViewById(R.id.btnZero); zero.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { mp.start(); } }); } } </code></pre> <p>Hope that helps!</p>
