如果第一个引用被转义，为什么Spannable fromHtml会给我错误的错误输出？它删除了第一句话

Question

请阅读底部的编辑更新。

我对Android很新，所以请耐心等待。我能用一个非常简单的例子重现我的问题。

我的strings.html中有以下内容：

<string name="nice_html">
<![CDATA[
<div><p><strong><a href=\"https://www.reddit.com/r/nosleep/comments/3ijnt6/im_a_search_and_rescue_officer_for_the_us_forest/">Timeline</a> of my other stories separated by company.</strong></p><p><a href=\"https://redd.it/7jmvxo\">This</a> story about smashing modems from <a href=\"/u/devdevo1919\">u/devdevo1919</a> reminded of this little gem when I was a customer service representative at $SecurityCompany. Now before you say \u201cbut customer service isn\u2019t IT\u201d, let me explain the position. They <em>called</em> us CSRs, but what we really did was mostly technical support for the residential and small business security systems as well as some customer service functions. We had a separate team for the large businesses.</p></div>
]]>
</string>

我的mainactivity.xml如下所示：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.pranapps.htmltest.MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text=""
        android:id="@+id/mylabel"
        android:layout_marginTop="25dp"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        />

</android.support.constraint.ConstraintLayout>

活动代码如下：

TextView mylabel = (TextView) findViewById(R.id.mylabel);

        String htmlstring = getString(R.string.nice_html);
        Spannable spannable = (Spannable) Html.fromHtml(htmlstring);
        System.out.println("htmlstring: "+htmlstring);
        System.out.println("spannable: "+spannable);
        mylabel.setText(spannable);

这给了我错误的输出。注意输出中缺少字符串的整个第一行，整个字符串显示为粗体。

system.out表示Spannable是导致问题的那个，并且由于某种原因它正在修剪整个第一行。有人可以帮助我为什么这样做？

编辑：我想通了，但我很好奇这是不是一个错误。如果我仅移除\标记后的第一个href=，则它会开始正常运行。这是一个错误吗？

Answer 1

您的HTML位于CDATA块中。 AFAIK，你不需要在那里使用引号。但是，如果你这样做，你显然需要这样做。

您的第二个<a>是：

<a href=\"https://redd.it/7jmvxo\">

请注意，您有两个使用反斜杠转义的引号。

您的第一个<a>是：

<a href=\"https://www.reddit.com/r/nosleep/comments/3ijnt6/im_a_search_and_rescue_officer_for_the_us_forest/">

请注意，您已经转过了开头的引号，但没有转过右引号。

根据您的评论，您修复的<a>是：

<a href="https://www.reddit.com/r/nosleep/comments/3ijnt6/im_a_search_and_rescue_officer_for_the_us_forest/">

如果可以，那么你不需要在这里转义引号，因为它们没有被转义。

所以，我会删除逃生反斜杠，以简化你的生活。
