android – 按下时在文本视图中突出显示单词

我有一个TextView来显示一段文字,我希望我的应用程序在按下时使用TTS说出单个单词.如果按下时可以突出显示单词会更好看.我已经使用ClickableSpan为每个单词实现了它.它工作得很好,除了我没有看到如何在播放完成后将突出显示的状态重置为正常状态.每次我点击一个新单词时,前一个单词都会丢失突出显示,而新单词会突出显示,但是一旦TTS回调,我不知道如何删除突出显示：

我的TextView：

<TextView
    android:id="@+id/sentence"
    ...
    android:textColorHighlight="@color/i_blue"
 />

要填写TextView,我使用：

SpAnnableStringBuilder strBuilder = new SpAnnableStringBuilder();
Iterator<Word> iterator = e.getWordList().iterator();
int wordStart,wordEnd;
while (iterator.hasNext()) {
    Word w =  iterator.next();
    wordStart = strBuilder.length() + w.getPrefix().length();
    wordEnd = wordStart + w.getWord().length();
    strBuilder.append(w.getPrefix() + w.getWord() + w.getSuffix());
    final String currentWord = w.getWord();
    ClickableSpan readWord = new ClickableSpan() {
        private String clickedWord = currentWord;
        public void onClick(View view) {
            message msg = m_HandlerReadWord.obtainmessage();
            msg.obj = clickedWord;
            m_HandlerReadWord.sendmessage(msg);
        }
        @Override
        public void updateDrawState(TextPaint ds) {
            super.updateDrawState(ds);
            ds.setUnderlineText(false);
        }
    };
    strBuilder.setSpan(readWord,wordStart,wordEnd,0);
}
m_SentenceView.setText(strBuilder);
m_SentenceView.setMovementMethod(LinkMovementMethod.geTinstance());

而且我也有这个方法,一旦TTS在完成播放单词时回调,就会调用它：

public void resetHighlight() {
 //what can I do there to reset any highlighted word?
}

有没有办法可以做到？或者有比ClickableSpan更好的方法吗？

final int almostBlack = m_resources.getColor(R.color.i_black_almost);
ClickableSpan readWord = new ClickableSpan() {
    private int almostBlack = AlmostBlack;
    public void onClick(View view) {
        TextView v = (TextView) view;
        v.setTextColor(almostBlack);
        ...
