Question

我正在构建可在单击按钮时发出提示音的应用程序。但是单击14次后声音停止。代码在这里：

Answer 1

无需在每次单击按钮时进行初始化。

private MediaPlayer _mediaPlayer;

@Override
protected void onResume()
{
    super.onResume();
    _mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.tic_sound);
    _mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
}

@Override
protected void onCreate(@Nullable Bundle savedInstanceState)
{
    //...

    dTextVeiw.setOnClickListener(new View.onClickListener() {
        @Override
        public void onClick(View view) {
            _mediaPlayer.start();
        } 
    });
}

Answer 2

对于简短的声音，我建议使用SoundPool

Class SoundPlayer(){

private final static float leftVol = 1.0f;
private final static float rightVol = 1.0f;
private final static float rate  = 1.0f;
private final static int loop = 0;
private  int priority  = 1;
private int audioId = = -1;

AudioAttributes attributes = new AudioAttributes.Builder()
    .setUsage(AudioAttributes.USAGE_GAME)
    .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
    .build();

 SoundPool soundPool= new SoundPool.Builder()
.setMaxStreams(2)
.setAudioAttributes(attributes)
.build();

public void loadSounds(Context context){
audioId = soundPool.load(context, R.raw.tic_sound, priority);
}

  public void playAudio() {  
   soundPool.play(audioId, leftVol, rightVol, priority, loop, rate) ;    
 }
}

并像这样使用它

private SoundPlayer soundPlayer;

 .... 
 ....
onCreate ...{
soundPlayer = SoundPlayer();
soundPLayer.loadSounds(this);


dTextVeiw.setOnClickListener(new View.onClickListener() {
@Override
public void onClick(View view){

 soundPLayer.playAudio();
}

单击14次后，Mediaplayer停止工作
