Question

我正在制作具有声音样本的词典应用程序，当单击列表中的项目时，将打开包含详细信息视图和按钮的新活动。有人可以帮助我如何将特定声音分配给按钮。声音文件放在原始文件夹中。例如，我点击了项目＆＃39; araw＆＃39;，详细信息将显示，按钮必须播放声音...请帮助我...

继承人的代码：

ListView lv;
SearchView sv;


String[] tagalog= new String[] {"alaala (png.)","araw (png.)","baliw (png.)","basura (png.)",
        "kaibigan (png.)","kakatuwa (pu.)", "kasunduan (png.)","dambuhala (png.)",
        "dulo (png.)","gawin (pd.)","guni-guni (png.)","hagdan (png.)","hintay (pd.)",

ArrayAdapter<String> adapter;

    adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,tagalog);
    lv.setAdapter(adapter);
    lv.setOnItemClickListener(new OnItemClickListener() {

    });

}

    @Override

    }

    play.setOnClickListener(new View.OnClickListener() {

Answer 1

像佩迪夫所说，你应该使用SoundPool播放短音。

以下是我的俄罗斯方块游戏中的代码，活动创建实例并在加载声音时获得回调。

单身人士的例子：

public class Sounds {

    private Context ctx;
    private static Sounds mSounds = null;

    private static SoundPool mSPool = null;
    private int sound_gameover;
    private int sound_teil_drehen;
    private int sound_1_zeile;
    private int sound_2_zeile;
    private int sound_3_zeile;
    private int sound_4_zeile;

    private int soundsToLoad = 6;
     /**
     *   Volumecontrol
     */
    private AudioManager audioManager;
    private float actualVolume;
    private float maxVolume;
    private float volume;

    private IOnSoundReady callback = null;

    public static Sounds getInstance(Context ctx, IOnSoundReady mCallback){
        if(mSPool == null){
            mSounds =  new Sounds(ctx, mCallback);
        }
        return mSounds;
    }

    private Sounds(Context ctx, IOnSoundReady mIOSoundReady) {
        this.ctx = ctx;
        this.callback = mIOSoundReady;
        initVolume();

        AsyncTask<Void, Void, Void> mTask = new AsyncTask<Void, Void, Void>() {
            @Override
            protected Void doInBackground(Void... params) {
                initSoundPool();
                return null;
            }
        };
        mTask.execute();
    }

    public void unprepare() { 
        if (mSPool == null) return;
        mSPool.release();
        mSPool = null;
    } 

    private void initSoundPool(){

        mSPool = new SoundPool(6, AudioManager.STREAM_MUSIC, 0);

        mSPool.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {
            @Override
            public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
                Log.w(TAG, "loaded soundid: " + sampleId);
                if(--soundsToLoad == 0 && callback != null){
                    callback.onSoundReady();
                }
            }
        });

        sound_gameover = mSPool.load(ctx, R.raw.game_over, 1);
        sound_teil_drehen = mSPool.load(ctx, R.raw.rotate, 1);
        sound_1_zeile = mSPool.load(ctx, R.raw.line_1,1);
        sound_2_zeile = mSPool.load(ctx, R.raw.line_2, 1);
        sound_3_zeile = mSPool.load(ctx, R.raw.line_3, 1);
        sound_4_zeile = mSPool.load(ctx, R.raw.line_4, 1);

    }

    /**
     * calculate volume
     */
    private void initVolume(){
        audioManager = (AudioManager) ctx.getSystemService(SpielActivity.AUDIO_SERVICE);
        actualVolume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
        maxVolume = (float) audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
        volume = actualVolume / maxVolume;
    }            

    /**
     * plays a sound
     * @param soundid 
     */
    public void playSound(int soundid){
        mSPool.play(soundid, volume, volume,1, 0, 1f);
    }
}

加载声音时使用的接口，由活动实现：

public interface IOnSoundReady {
    void onSoundReady();
}

您活动中的用法：

Sounds mySounds = Sounds.getInstance(this, this);

播放声音：

public static void playSound(int soundid) {
    mySounds.playSound(soundid);
}

希望我能帮上忙。

Answer 3

您必须使用SoundPool。

对于较短的声音效果，您可以使用SoundPool，否则您应该使用MediaPlayer。

单击项目时必须播放特定声音
