如何在Recyclerview适配器中使用越来越少的链接设置textview

Question

我有一个TextView，用于显示链接越来越少的大型文本。我的TextView适配器中有RecyclerView。当我启动应用程序时，它会显示正确的文本，但是当我向下滚动并再次向上滚动时，有时文本会消失，有时文本会被交换，有时它不再出现。

我使用以下代码：

CreateView Holder代码：

public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
        return new ListItemHolder(inflater.inflate(mLayoutResID, viewGroup, false));
}


@Override
    public void onBindViewHolder(RecyclerView.ViewHolder viewHolder, final int position) {

    mList = (dataList) this.dataList.get(position);
final ListItemHolder listItemHolder = (ListItemHolder) viewHolder;

listItemHolder.mBodyText = mList.getmBody();
makeExpandable(listItemHolder.mBodyText, listItemHolder.mBodyTextView);

}

public void makeExpandable(String descriptionText, final TextView textView) {

    MORE = mContext.getResources().getString(R.string.more_content);
    LESS = " " + mContext.getResources().getString(R.string.less_content);
    CharSequence body = Html.fromHtml(descriptionText);
    final SpannableString text = new SpannableString(body);
    mTitleBodyTextView = textView;

    final int maxChar = 150;
    final ViewTreeObserver vto = textView.getViewTreeObserver();
    textView.setTextColor(mContext.getResources().getColor(R.color.black));

    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            ViewTreeObserver obs = textView.getViewTreeObserver();
            obs.removeOnGlobalLayoutListener(this);
            lineEndIndex = 150;
            textView.setMovementMethod(LinkMovementMethod.getInstance());
            showLess(text, maxChar, textView);
        }
    });

}


/**
 * truncate text and append a clickable {@link #MORE}
 */
private void showLess(final SpannableString text, final int maxChar, final TextView textView) {

    final String newText = text.subSequence(0, lineEndIndex - (ELLIPSIZE.length() +
            MORE.length() + 1)).toString() + ELLIPSIZE + MORE;
    SpannableStringBuilder builder = new SpannableStringBuilder(newText);

    builder.setSpan(new ClickableSpan() {
        @Override
        public void onClick(View widget) {
            showMore(text, maxChar, textView);
        }

        @Override
        public void updateDrawState(TextPaint ds) {
            super.updateDrawState(ds);
            ds.setUnderlineText(false);
            ds.setColor(mContext.getResources().getColor(R.color.grey_dark));
        }
    }, newText.length() - MORE.length(), newText.length(), 0);

    textView.setText(builder, TextView.BufferType.SPANNABLE);
}

/**
 * show full text and append a clickable {@link #LESS}
 */
private void showMore(final SpannableString text, final int maxChar, final TextView textView) {
    // create a text like subText + ELLIPSIZE + MORE
    SpannableStringBuilder builder = new SpannableStringBuilder(text + LESS);

    builder.setSpan(new ClickableSpan() {
        @Override
        public void onClick(View widget) {
            showLess(text, maxChar, textView);
        }

        @Override
        public void updateDrawState(TextPaint ds) {
            super.updateDrawState(ds);
            ds.setUnderlineText(false);
            ds.setColor(mContext.getResources().getColor(R.color.grey_dark));
        }
    }, builder.length() - LESS.length(), builder.length(), 0);

    textView.setText(builder, TextView.BufferType.SPANNABLE);

}
