【中文标题】SoundPool 没有播放？

【问题描述】：

我有 2 个SoundPool 实例，如果我运行我的应用程序，soundPool2 运行与soundPool1 相同的声音，我不知道为什么会播放相同的声音。谁能帮我找出问题所在？

public class MainActivity extends Activity implements OnTouchListener 
private SoundPool soundPool;
private SoundPool soundPool2;
private int soundID;
private int soundID2;
boolean loaded = true;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    View view = findViewById(R.id.button1);
    view.setOnTouchListener(this);

    // Set the hardware buttons to control the music
    this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
    // Load the sound
    soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
    soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener()
    
        @Override
        public void onLoadComplete(SoundPool soundPool, int sampleId,
                int status) 
            loaded = true;
        
    );

    soundID = soundPool.load(this, R.raw.sound1, 1);

    View view2 = findViewById(R.id.button2);
    view2.setOnTouchListener(this);
    this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
    soundPool2 = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
    soundPool2.setOnLoadCompleteListener(new OnLoadCompleteListener()
    
        @Override
        public void onLoadComplete(SoundPool soundPool2, int sampleId,
                int status) 
            loaded = true;


        
    );


    soundID2 = soundPool.load(this, R.raw.bird, 1);



public boolean onTouch( View v, MotionEvent event) 
    if (event.getAction() == MotionEvent.ACTION_DOWN) 
        // Getting the user sound settings
        AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
        float actualVolume = (float) audioManager
                .getStreamVolume(AudioManager.STREAM_MUSIC);
        float maxVolume = (float) audioManager
                .getStreamMaxVolume(AudioManager.STREAM_MUSIC);
        float volume = actualVolume / maxVolume;
        // Is the sound loaded already?
        if (loaded) 
            soundPool.play(soundID, volume, volume, 1, 0, 1f);
            Log.e("Test", "Played ");
        
    
    return false;


public boolean onTouch2( View v, MotionEvent event) 
if (event.getAction() == MotionEvent.ACTION_DOWN) 
    // Getting the user sound settings
    AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
    float actualVolume = (float) audioManager
            .getStreamVolume(AudioManager.STREAM_MUSIC);
    float maxVolume = (float) audioManager
            .getStreamMaxVolume(AudioManager.STREAM_MUSIC);
    float volume = actualVolume / maxVolume;
    // Is the sound loaded already?
    if (loaded) 
        soundPool2.play(soundID2, volume, volume, 1, 0, 1f);
        Log.e("Test", "Played sound");
    

return false;

【参考方案1】：

首先，您只需要一个 SoundPool 实例，而不是两个。

另外，你的onTouch 和onTouch2 对我来说没有多大意义，那里也可能有问题，所以我也重写了那部分。

请尝试以下代码。

public class MainActivity extends Activity implements OnTouchListener 
    private SoundPool mSoundPool;
    private int mSoundID;
    private int mSoundID2;
    private boolean mSoundLoaded = false;
    private float mVolume = 0f;

    @Override
    public void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        View view = findViewById(R.id.button1);
        view.setOnTouchListener(this);
        View view2 = findViewById(R.id.button2);
        view2.setOnTouchListener(this);

        // Set the hardware buttons to control the music
        this.setVolumeControlStream(AudioManager.STREAM_MUSIC);

        // Load the sound
        mSoundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
        mSoundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() 
            @Override
            public void onLoadComplete(SoundPool soundPool, int sampleId, int status) 
                if (sampleId == R.raw.bird) 
                    mSoundLoaded = true;
                
            
        );

        mSoundID = mSoundPool.load(this, R.raw.sound1, 1);
        mSoundID2 = mSoundPool.load(this, R.raw.bird, 1);

        // Getting the user sound settings
        AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
        float actualVolume = (float) audioManager
                .getStreamVolume(AudioManager.STREAM_MUSIC);
        float maxVolume = (float) audioManager
                .getStreamMaxVolume(AudioManager.STREAM_MUSIC);
        mVolume = actualVolume / maxVolume;
    

    public boolean onTouch(View v, MotionEvent event) 
        if (event.getAction() == MotionEvent.ACTION_DOWN) 
            // Is the sound loaded already?
            if (mSoundLoaded) 
                if (v.getId() == R.id.button1) 
                    playSound(mSoundID);
                    Log.e("Test", "Played mSoundID");
                 else if (v.getId() == R.id.button2) 
                    playSound(mSoundID2);
                    Log.e("Test", "Played mSoundID2");
                
            
        
        return false;
    

    private void playSound(int soundId) 
        mSoundPool.play(soundId, mVolume, mVolume, 1, 0, 1f);
    

注意：可能有错误，是未经测试的代码。

非常感谢老师，它的作品，我测试过，完美！！！ :) ，然后运行 ​​find .. 再次感谢，我是新手，我必须学习更多。呵呵@Tigger

很高兴能提供帮助。

@Tigger 嘿触发器我需要你的声音池帮助。这是一个简单的代码，请邀请我到聊天室。谢谢！
