Question

我想在我的Android应用程序中弹出我的吐司时发出声音。

这是我的主要课程中的吐司代码：

private void workEndNotification() {
    //Custom Toast notification for the Work End Reminder.
    LayoutInflater inflaterWork = getLayoutInflater();
    View toastLayout = inflaterWork.inflate(R.layout.work_notification_toast, (ViewGroup) findViewById(R.id.toast_root_view));
    TextView header = (TextView) toastLayout.findViewById(R.id.toast_header);
    header.setText("Work Day Over Soon!");
    final Toast toastWork = new Toast(getApplicationContext());
    toastWork.setGravity(Gravity.CENTER, 0, 0);
    toastWork.setDuration(Toast.LENGTH_SHORT);
    toastWork.setView(toastLayout);
    toastWork.show();

    myHandler.postDelayed(new Runnable() {
        public void run() {
            toastWork.cancel();
        }
    }, 1);
};

以下是我的SoundPool类（http://www.vogella.com/tutorials/AndroidMedia/article.html）中的声音代码：

class PlaySound extends Activity implements OnTouchListener {
private SoundPool soundPool;
private int soundID;
boolean loaded = false;


/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.work_notification_toast);
    View view = findViewById(R.id.toast_header);
    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);

}

@Override
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 sound");
        }
    }
    return false;
}
}

我知道我没有用吐司方法调用它，而且我知道我正在使用touchview。如何才能使声音仅在吐司出现时同时出现。我一直在努力，但还没有成功。

我不想要触摸或任何东西。只是为了与吐司一起玩。

制作这样的功能

private void playSound(int resId){
    mp = MediaPlayer.create(MainActivity.this, resId);
       mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        @Override
        public void onCompletion(MediaPlayer mediaPlayer) {
            mediaPlayer.reset();
            mediaPlayer.release();
        }
    });
    mp.start();
}

并将其称为显示Toast的地方

playSound(R.raw.sound);

您还需要替换资源，使其与您的资源相匹配

编辑：您似乎想要播放几种声音。您可以自己创建一个简单的声音池

创建一个你想要播放的int数组或资源，并在MediaPlayer完成播放时监听，告诉他播放下一个，直到它播放数组中的最后一个。

public class TestActivity extends Activity implements MediaPlayer.OnCompletionListener {


    private final int[] soundResources = {R.raw.sound1, R.raw.sound2, R.raw.sound3};
    private int counter = 0;
    private MediaPlayer mp;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        playSound(counter);
    }

    private void playSound(int resId){
        mp = MediaPlayer.create(TestActivity.this, resId);
        mp.setOnCompletionListener(this);
        mp.start();
    }

    @Override
    public void onCompletion(MediaPlayer mediaPlayer) {
        mp.reset();
        mp.release();
        if(counter < soundResources.length ) {
            playSound(soundResources[++counter]);
        }
    }
}
