在TextView中使用的大小HTML属性 [英] Using size HTML attribute in TextView

问题描述

我有以下几点：

textView.setText(Html.fromHtml("<font color=\"red\" size=\"24\">Hello</font>"));

字符串'hello'不变成红色，但规模不会改变。

The string 'Hello' does turn red but the size does not change.

这是因为如果大小属性不理，没有人知道这是为什么？难道我做错了什么？

It is as if the size attribute is just ignored, does anyone know why this is? Am I doing something wrong?

推荐答案

是，大小属性只忽略。只有色和面子的属性考虑到了。

Yes, size attribute just ignored. Only "color" and "face" attributes takes into account.

private void handleStartTag(String tag, Attributes attributes) {
    if (tag.equalsIgnoreCase("br")) {
        // We don't need to handle this. TagSoup will ensure that there's a </br> for each <br>
        // so we can safely emite the linebreaks when we handle the close tag.
    }
    ...
    else if (tag.equalsIgnoreCase("font")) {
        startFont(mSpannableStringBuilder, attributes);
    }
    ...
}

private static void startFont(SpannableStringBuilder text,
                              Attributes attributes) {
    String color = attributes.getValue("", "color");
    String face = attributes.getValue("", "face");

    int len = text.length();
    text.setSpan(new Font(color, face), len, len, Spannable.SPAN_MARK_MARK);
}
