通过在字幕文件中添加额外的特殊字幕来解决问题。这些字幕将在添加到媒体播放器后一段时间后触发，该时间等于该字幕的持续时间。

以下是包含代码示例的解决方案：

private void addSpecialSubtitle(String subtitlePath) {
    try {
        InputStream is = new FileInputStream(subtitlePath);
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        String line;
        int index = 1;
        while ((line = reader.readLine()) != null) {
            if (line.contains("-->")) { // check for time portion of subtitle
                String[] parts = line.split("-->");
                long startTime = parseSRTTime(parts[0].trim());
                long endTime = parseSRTTime(parts[1].trim());
                if (endTime > startTime) { // only add special subtitle if it has a duration
                    MediaPlayer mediaPlayer = new MediaPlayer();
                    mediaPlayer.setDataSource(subtitlePath);
                    mediaPlayer.setOnTimedTextListener(new MediaPlayer.OnTimedTextListener() {
                        @Override
                        public void onTimedText(MediaPlayer mp, TimedText text) {
                            if (text != null && text.getText().equals("SPECIAL_SUBTITLE_" + index)) {
                                // handle end of special subtitle
                            }
                        }
                    });
                    mediaPlayer.prepare();
                    mediaPlayer.addTimedTextSource(subtitlePath, MediaPlayer.MEDIA_MIMETYPE_TEXT_SUBRIP);
                    mediaPlayer.selectTrack(mediaPlayer.getTrackInfo()[0].getTrackId());
                    mediaPlayer.seekTo((int) startTime);
                    mediaPlayer.start();
                    mp.addTimedText("SPECIAL_SUBTITLE_" + index, endTime - startTime, startTime);
                    index++;
                }
            }
        }
    } catch (Exception e) {
        Log.e(TAG, "addSpecialSubtitle: ", e);
    }
}

private long parseSRTTime(String srtTime) {
    String[] parts = srtTime.split(":");
    long hours = Long.parseLong(parts[0].trim());
    long minutes = Long.parseLong(parts[1].trim());
    String[] secondsParts =
