blocks|key|319087|text|在我的例子中，我的数据来自于API调用。我仍然需要输出来匹配我的应用程序的格式，所以我将formatting封装在格式化标签中以显示在我的WebView中：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|319088|public+static+String+formatHtmlString(String+stringIn)+{

Im my case my data is coming down from an API call. I still needed the output to match the format of my app so I wrap the HTML string in formatting tags to display in my WebView:

<pre><code>public static String formatHtmlString(String stringIn) {

 String format = "&lt;html&gt;"
 + " &lt;head&gt;"
 + " &lt;style type='text/css'&gt;"
 + " body { "
 + " font-family: \"HelveticaNeue-Light\", \"Helvetica Neue Light\"; "
 + " font-size:14px;" + " color:#000;"
 + " }" + " b { " + " font-size:14px;"
 + " }" + " i { " + " font-size:10px;"
 + " color:#333333;" + " opacity:0.75;"
 + " }" + " &lt;/style&gt;" + " &lt;/head&gt;" + " &lt;body&gt;"
 + stringIn + "&lt;/body&gt;" + "&lt;/html&gt;";

 return format;
}
</code></pre>

blocks|key|536088|text|根据下面的答案，你不能在这里使用所有的HTML标签；|type|unstyled|depth|inlineStyleRanges|entityRanges|data|536089|https://stackoverflow.com/a/3150456/2275962|offset|length|536090|但是，当然，在Android+TextView中有一种显示项目符号的方式。您可以将<li>标记替换为&#149;+(这是项目符号的HTML码)。|style|CODE|536091|如果您想尝试其他列表图标，请使用表格中的首选图标是此链接；|536092|http://www.ascii-code.com/|536093|entityMap|0|LINK|mutability|MUTABLE|url|1^0|0|0|17|0|0|15|4|1E|6|0|0|0|Q|1|0^^$0|@$1|2|3|4|5|6|7|V|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|W|8|@]|9|@$D|X|E|Y|1|Z]]|A|$]]|$1|F|3|G|5|6|7|10|8|@$D|11|E|12|H|I]|$D|13|E|14|H|I]]|9|@]|A|$]]|$1|J|3|K|5|6|7|15|8|@]|9|@]|A|$]]|$1|L|3|M|5|6|7|16|8|@]|9|@$D|17|E|18|1|19]]|A|$]]|$1|N|3|-4|5|6|7|1A|8|@]|9|@]|A|$]]]|O|$P|$5|Q|R|S|A|$T|C]]|U|$5|Q|R|S|A|$T|M]]]]

According to the answer below, you can not use every HTML tag here;

<a href="https://stackoverflow.com/a/3150456/2275962">https://stackoverflow.com/a/3150456/2275962</a>

But, sure, there ise a way of showing bullets in Android TextView. You can replace <code>&lt;li&gt;</code> tags with <code>&amp;#149;</code> (which is HTML code for bullet). 

If you want to try other list icons, use the preferred one from the table is this link;

blocks|key|319196|text|您可以使用Html.TagHandler。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|319197|在您的示例中，它将如下所示：|319198|public+class+UlTagHandler+implements+Html.TagHandler{
++++@Override
++++public+void+handleTag(boolean+opening,+String+tag,+Editable+output,
++++++++++++++++++++++++++XMLReader+xmlReader)+{
++++++++++++if(tag.equals("ul")+&&+!opening)+output.append("\n");
++++++++++++if(tag.equals("li")+&&+opening)+output.append("\n\t•");
++++}
}|code-block|syntax|javascript|319199|和|319200|textView.setText(Html.fromHtml(myHtmlText,+null,+new+UlTagHandler()));|319201|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Q|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

You can use Html.TagHandler.

In your case it will be like this:

<pre><code>public class UlTagHandler implements Html.TagHandler{
 @Override
 public void handleTag(boolean opening, String tag, Editable output,
 XMLReader xmlReader) {
 if(tag.equals("ul") &amp;&amp; !opening) output.append("\n");
 if(tag.equals("li") &amp;&amp; opening) output.append("\n\t•");
 }
}
</code></pre>

and

<pre><code>textView.setText(Html.fromHtml(myHtmlText, null, new UlTagHandler()));
</code></pre>

blocks|key|319264|text|要让API级别M+(23)及更低级别的应用程序接口正常工作，一个非常简单的方法就是在HTML字符串中使用以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|319265|private+fun+String.formattedHtml():+String+{
++++//+Work+around+for+API+Versions+lower+than+N,+Html.fromHtml+does+not+render+list+items+correctly
++++return+if+(Build.VERSION.SDK_INT+<+Build.VERSION_CODES.N)+{
++++++++this.replace("<ul>",+"")
++++++++++++.replace("</ul>",+"")
++++++++++++.replace("<li>",+"•+")
++++++++++++.replace("</li>",+"")
++++}+else+{
++++++++this
++++}
}|code-block|syntax|javascript|319266|然后，您可以使用：|319267|Html.fromHtml("<ul><li>+test+</li></ul>".formattedHtml())|319268|API+N及以上版本无需TagHandler，如https://stackoverflow.com/a/40524835中所述，android.text.Html支持li和ul标签。|offset|length|style|CODE|319269|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/40524835^0|0|0|0|0|C|A|1S|H|2B|2|2E|2|O|10|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|Z|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|10|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|11|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|12|8|@$M|13|N|14|O|P]|$M|15|N|16|O|P]|$M|17|N|18|O|P]|$M|19|N|1A|O|P]]|9|@$M|1B|N|1C|1|1D]]|A|$]]|$1|Q|3|-4|5|6|7|1E|8|@]|9|@]|A|$]]]|R|$S|$5|T|U|V|A|$W|X]]]]

A really easy way to make things work for API level M (23) and lower
From your HTML string you can use the following:

<pre><code>private fun String.formattedHtml(): String {
 // Work around for API Versions lower than N, Html.fromHtml does not render list items correctly
 return if (Build.VERSION.SDK_INT &lt; Build.VERSION_CODES.N) {
 this.replace("&lt;ul&gt;", "")
 .replace("&lt;/ul&gt;", "")
 .replace("&lt;li&gt;", "&lt;p&gt;• ")
 .replace("&lt;/li&gt;", "&lt;/p&gt;")
 } else {
 this
 }
}
</code></pre>

Then, you can use:

<pre><code>Html.fromHtml("&lt;ul&gt;&lt;li&gt; test &lt;/li&gt;&lt;/ul&gt;".formattedHtml())
</code></pre>

No need for <code>TagHandler</code> for API N and up, as mentioned in <a href="https://stackoverflow.com/a/40524835">https://stackoverflow.com/a/40524835</a>, <code>android.text.Html</code> supports <code>li</code> and <code>ul</code> tags.

I have String with ul and li in it. And I am trying to show them in HTML formatting in textview. <code>textView.setText(Html.fromHtml(myHtmlText));</code> 
But textview shows the plain text. How can I have the ul and li tags formatted in textview?

Show <ul> <li> in android textview

Android

我有一个包含ul和li的字符串。我正在尝试在textview中以HTML格式显示它们。textView.setText(Html.fromHtml(myHtmlText));但是textview显示的是纯文本。如何在textview中设置ul和li标记的格式？
