I'm starting to play with doing some simple animations.
I have one where I want a sound and animation to play every X seconds
after a button is pressed.
So I set it up like this:
private ScheduledThreadPoolExecutor threadRunner = new
ScheduledThreadPoolExecutor(
4);
private SoundPlayer mSoundPlayer = new SoundPlayer();
private ScheduledFuture<SoundPlayer> playerFuture = null;
private OnClickListener mClickButton = new OnClickListener() {
public void onClick(View v) {
Button button = (Button) findViewById(R.id.Button01);
if (playerFuture != null) {
button.setText(R.string.Button01);
playerFuture.cancel(false);
playerFuture = null;
} else {
button.setText(R.string.BtnStop);
playerFuture = (ScheduledFuture<SoundPlayer>)
threadRunner.scheduleAtFixedRate(mSoundPlayer,
0, 3000, TimeUnit.MILLISECONDS);
}
return;
}
};
private class SoundPlayer implements Runnable {
private MediaPlayer mPlayer;
private TextView testShape;
private Animation testAnimation;
public void run() {
if (mPlayer == null) {
mPlayer = MediaPlayer.create(getBaseContext(),
R.raw.ding);
testShape = (TextView)
findViewById(R.id.TextView02);
testAnimation =
AnimationUtils.loadAnimation(getBaseContext(),
R.anim.testanim);
}
mPlayer.start();
testShape.startAnimation(testAnimation);
return;
}
}
The problem is that the call to "startAnimation" seems to stop the
timer.
The sequence of events is:
Press Button (starts timer)
Sound plays once
Press Button (to stop the timer)
Animation plays once
Press Button (starts timer)
Sound & Animation play once
Press Button (stops timer)
nothing happens
Press Button (starts timer)
Sound & Animation play once
...
If I remove the call to testShape.startAnimation(), the timer runs,
and the sound plays every 3 seconds until the button is pressed again.
I must be doing something wrong with the animation, but I haven't been
able to figure out what.
