android - 在对话框中播放声音

我想在对话框中播放声音。对话框中有一个gif动画，现在我也想在其中添加声音。我正在尝试此代码，但没有帮助。我只能够播放gif动画。请帮忙。

ImageButton bicycle = (ImageButton)findViewById(R.id.imageButton1);
    bicycle.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            AlertDialog.Builder builder = new AlertDialog.Builder(Vehicles.this);
            WebView view = new WebView(Vehicles.this);
            view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
            builder.setView(view);
            //builder.create().show();

            final Dialog d = builder.create(); // save a Dialog reference here
            d.show();

            view.loadUrl("file:///android_asset/bicycle.gif");

                    soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 1);
        mMediaPlayer = new MediaPlayer();
            mMediaPlayer = MediaPlayer.create(Vehicles.this, R.raw.bicycle);
            mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            mMediaPlayer.start();

        soundIsPlaying = true;

        new Handler().postDelayed(new Runnable() {
                public void run() {
                    soundIsPlaying = false;
                }
            }, PLAYING_TIME_OF_SOUND);

            gifIsPlaying = true;

            new Handler().postDelayed(new Runnable() {
                public void run() {
                    gifIsPlaying = false;
                    //finish();

                    if (d.isShowing()) { // dismiss dialog if still showing
                        d.dismiss();
                    }
                }
            }, PLAYING_TIME_OF_GIF);

        }
    });

最佳答案

您应该在MediaPlayer中使用mediaPlayer.release()释放setOnCompletionListener的资源
