Android声音文件没有完全播放,遭到残酷的打击

Question

脚本

我有一个问题,开始让我疯了.在一个活动中,我有以下场景.在创建: - 创建一个GPS听者 - 创建一个位置监听器 - 启动GPS听者和位置监听器 - 开始从网上下载一个地图的AsyncTask /或从缓存中加载 - 播放WAV文件,该文件是原始资源,非常小(约63公斤),这是短,基本上是这样说的:"我们前往起点",它使可见一个TextView 10秒.

问题

声音很少得到充分发挥.有时候,我只听到"我们的头",有时是"让我们头明星",有时不玩的.这就像阻止声音的其他东西.我在自己的线程中移动了声音,但仍然没有成功:

码

private void ShowTextPlayVoice(String message, int soundResId)
    {
        txtProceed.setText(message);
        txtProceed.setVisibility(View.VISIBLE);
        final int soundId = soundResId;

        Handler splashHandler = new Handler() {
            @Override
            public void handleMessage(Message msg) {
                    switch (msg.what) {
                    case 0:
                            txtProceed.setVisibility(View.INVISIBLE);
                            break;
                    }
                    super.handleMessage(msg);
            }
        };

            Message msg = new Message();
            msg.what = 0;
            splashHandler.sendMessageDelayed(msg, 10000);

            Thread thread = new Thread() {
                public void run() {
                    MediaPlayer mp = MediaPlayer.create(ctx, soundId);
                    mp.start();
                    mp.setOnCompletionListener(new OnCompletionListener() {
                                    public void onCompletion(MediaPlayer mp) {
                                        mp.release();
                                    }
                                });
                }
            };
            thread.start();
    }

谢谢大家的帮助.

经过一番尝试,这是一个有效的解决方案

private MediaPlayer mediaPlayer = new MediaPlayer();

private void ShowTextPlayVoice(String message, int soundResId)
    {
        txtProceed.setText(message);
        txtProceed.setVisibility(View.VISIBLE);

        Handler splashHandler = new Handler() {
            @Override
            public void handleMessage(Message msg) {
                    switch (msg.what) {
                    case 0:
                            txtProceed.setVisibility(View.INVISIBLE);
                            break;
                    }
                    super.handleMessage(msg);
            }
        };

            Message msg = new Message();
            msg.what = 0;
            splashHandler.sendMessageDelayed(msg, 10000);

           new SoundTask().execute(soundResId);
    }

    protected class SoundTask extends AsyncTask<Integer, Void, Void>
    {
        @Override
        protected Void doInBackground(Integer... params) 
        {
            AssetFileDescriptor afd = ctx.getResources().openRawResourceFd(params[0]);

            try
            {   
                //final MediaPlayer mediaPlayer = new MediaPlayer();
                mediaPlayer.reset();
                mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
                mediaPlayer.prepare();
                mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
                    public void onPrepared(MediaPlayer arg0) {
                         mediaPlayer.seekTo(0);
                         mediaPlayer.start();
                                                });
                    }
                });
                afd.close();
            }
            catch (Exception e) {
            }

            return null;
        }
    }
