Spannable 和 Html 不能一起工作

  • 772

我用来spannable在应用程序中实现脚注：

 private SpannableStringBuilder addClickablePart(String str) {
    SpannableStringBuilder ssb = new SpannableStringBuilder(str);

    int idx1 = str.indexOf("[");
    int idx2 = 0;

    while (idx1 != -1) {
        idx2 = str.indexOf("]", idx1) + 1;

        String clickString = str.substring(idx1, idx2);

        ssb.setSpan(new ClickableSpan() {

            @Override
            public void onClick(View widget) {

            }
        }, idx1, idx2, 0);
        idx1 = str.indexOf("[", idx2);
    }
    return ssb;
}

pageContent.setMovementMethod(LinkMovementMethod.getInstance());
pageContent.setText(addClickablePart(pageContentStr), TextView.BufferType.SPANNABLE);

如果setText我添加到方法Html.fromHtml()中，它会spannable停止工作，有没有办法将这两者结合起来，让两者都工作？

    首先使用Html.fromHtml此方法的结果应用并制作可点击的链接：

     private SpannableStringBuilder addClickablePart(String str) {
    CharSequence sequence = Html.fromHtml(str);

    SpannableStringBuilder ssb = new SpannableStringBuilder(sequence);

    int idx1 = str.indexOf("[");
    int idx2 = 0;

    while (idx1 != -1) {
        idx2 = str.indexOf("]", idx1) + 1;

        String clickString = str.substring(idx1, idx2);

        ssb.setSpan(new ClickableSpan() {

            @Override
            public void onClick(View widget) {

            }
        }, idx1, idx2, 0);
        idx1 = str.indexOf("[", idx2);
    }
    return ssb;
}
