我正在尝试在应用程序中播放声音。但是,我无法使用SoundPool。代码真的很简单,我看不出它会失败。
类似的代码,但是使用MediaPlayer确实可以,但是我对使用SoundPool感兴趣。
SoundPool代码:
private void playSound2(){
SoundPool sp = new SoundPool.Builder().build();
int soundID = sp.load(MainActivity.this, R.raw.sound, 1);
sp.play(soundID, 1, 1, 1, 0, 1);
}
上下文:
public void goButtonClick(View view){
Button goButton = findViewById(id.button2);
if (onGoing){
goButton.setText("GO!");
} else {
goButton.setText("STOP");
//playSound(); // MediaPlayer
playSound2(); // SoundPool
}
onGoing = !onGoing;
}
MediaPlayer版本(有效):
private void playSound(){
MediaPlayer mediaPlayer;
mediaPlayer = MediaPlayer.create(MainActivity.this, R.raw.sound);
mediaPlayer.start();
}
答案 0 :(得分:0)
解决了!
我没有等待将声音文件加载到soundPool中。正确的代码是:
private void playSound2() {
SoundPool sp = new SoundPool.Builder().build();
int soundID = sp.load(MainActivity.this, raw.sound, 1);
sp.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {
@Override
public void onLoadComplete(SoundPool sp, int soundID, int i1) {
sp.play(soundID, 1, 1, 1, 0, 1);
}
});
}
