[英]Android - How to mute SoundPool in TimerTask without stopping it
I am trying to create a metronome sound, however, what isn't working is the ability to mute it. 我正在尝试创建节拍器声音,但是,无法使它静音的功能。 I would like the ability to mute it without stopping the TimerTask since I want the rate to be consistent once it is unmuted.
我希望能够在不停止TimerTask的情况下将其静音,因为我希望速率在取消静音后保持一致。 Here is my code:
这是我的代码:
public class Metronome {
private boolean mute;
private boolean playing = false;
private Timer mainTimer;
private SoundPool mSoundPool;
int mSoundID;
public Metronome(Context context) {
mSoundPool = new SoundPool(2, AudioManager.STREAM_MUSIC, 0);
mSoundID = mSoundPool.load(context, R.raw.metronome, 1);
}
public void play(float pace, boolean mute) {
mainTimer = new Timer();
MyTimerTask mainTimerTask = new MyTimerTask();
mainTimer.schedule(mainTimerTask, 0, Math.round(pace * 1000));
this.mute = mute;
playing = true;
}
public void stop() {
mainTimer.cancel();
mainTimer.purge();
playing = false;
}
public boolean isPlaying() {
return playing;
}
public void setMute(boolean mute) {
this.mute = mute;
if (mute) {
mSoundPool.setVolume(mSoundID, 0, 0);
} else {
mSoundPool.setVolume(mSoundID, 1, 1);
}
}
private void playSound() {
if (!mute) {
mSoundPool.play(mSoundID, 1, 1, 1, 0, 1);
}
}
class MyTimerTask extends TimerTask {
@Override
public void run() {
playSound();
}
}
}
However, calling setMute(true)
does not work. 但是,调用
setMute(true)
不起作用。 Does anyone know how I can mute my SoundPool? 有人知道我如何使SoundPool静音吗?
Figured it out. 弄清楚了。 It works when I use static methods and variables.
当我使用静态方法和变量时,它可以工作。
public class Metronome {
public static boolean mute = false;
public static boolean playing = false;
private static Timer mainTimer;
private static SoundPool soundPool;
private static int soundID;
public static void loadSound(Context context) {
soundPool = new SoundPool(2, AudioManager.STREAM_MUSIC, 0);
soundID = soundPool.load(context, R.raw.metronome, 1);
}
public static void play(float pace, boolean isMuted) {
mainTimer = new Timer();
MyTimerTask mainTimerTask = new MyTimerTask();
mainTimer.schedule(mainTimerTask, 0, Math.round(pace * 1000));
mute = isMuted;
playing = true;
}
public static void stop() {
mainTimer.cancel();
mainTimer.purge();
playing = false;
}
static class MyTimerTask extends TimerTask {
@Override
public void run() {
playSound();
}
private void playSound() {
if (!mute) {
soundPool.play(soundID, 1, 1, 1, 0, 1);
}
}
}
}
