Question

我正在编写一个需要多次播放多个声音文件的游戏。

我正在使用MediaPlayer对象重新定位文件并在需要时每次播放。以下代码我正在使用：

try {
            if (commonPlayer.isPlaying()) {
                commonPlayer.stop();
                commonPlayer.release();
            }

            commonPlayer = null;

            switch (gameAction) {
                case 1:
                    commonPlayer = MediaPlayer.create(context, R.raw.tap);
                    break;

                case 2:
                    commonPlayer = MediaPlayer.create(context, R.raw.score);
                    break;

                case 3:
                    commonPlayer = MediaPlayer.create(context, R.raw.die);
                    break;
            }

            commonPlayer.start();

        } catch (Exception e) {
            log("Exception: " + e.getMessage());
        }

但是在多次播放后，它会停止播放以下错误：

有关如何多次播放声音文件的任何建议？

而不是

try {
            if (commonPlayer.isPlaying()) {
                commonPlayer.stop();
                commonPlayer.release();
            }

            commonPlayer = null;

            switch (gameAction) {
                case 1:
                    commonPlayer = MediaPlayer.create(context, R.raw.tap);
                    break;

                case 2:
                    commonPlayer = MediaPlayer.create(context, R.raw.score);
                    break;

                case 3:
                    commonPlayer = MediaPlayer.create(context, R.raw.die);
                    break;
            }

            commonPlayer.start();

        } catch (Exception e) {
            log("Exception: " + e.getMessage());
        }

试试这个

commonPlayer = null;

            switch (gameAction) {
                case 1:
                    commonPlayer = MediaPlayer.create(context, R.raw.tap);

          commonPlayer.setOnCompletionListener(new musicCompletionListener());

                    break;

                case 2:
                    commonPlayer = MediaPlayer.create(context, R.raw.score);
commonPlayer.setOnCompletionListener(new musicCompletionListener());

                    break;

                case 3:
                    commonPlayer = MediaPlayer.create(context, R.raw.die);
commonPlayer.setOnCompletionListener(new musicCompletionListener());

                    break;
            }

            commonPlayer.start();

        } 

 private class musicCompletionListener implements MediaPlayer.OnCompletionListener {
    @Override
    public void onCompletion(MediaPlayer mediaPlayer) {
        commonPlayer.release();
    }
}

播放时的记忆问题多次停止音频文件
