tv.setPaintFlags(tv.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

It looks like is not really supported, at least it does not work on Android 3.1.

@RMS2 if text is small you can split it into two or three separate text views and apply flag only to the one which you want, not perfect for long texts ;(

Here is a solution using a custom TagHandler you have to pass to Html.fromHtml().

blocks|key|5863852|text|@Suresh解决方案适用于如果你想删除整个TextView，但如果你只想删除文本的一部分，那么使用下面的代码。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5863853|++++tvMRP.setText(text,+TextView.BufferType.SPANNABLE);

@Suresh solution works if you want to strikethrough the entire TextView but if you want to strikethrough only some portions of the text then use the code below.

<pre><code> tvMRP.setText(text, TextView.BufferType.SPANNABLE);
 Spannable spannable = (Spannable) tvMRP.getText();
 spannable.setSpan(new StrikethroughSpan(), 3, text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
</code></pre>

Here <code>text</code> is the text which we want out TextView to display, <code>3</code> is the no. of characters (starting from 0) from where the strikethrough will start.

You can do it with a custom <code>TagHandler</code> such as the one <a href="https://stackoverflow.com/questions/4044509/android-how-to-use-the-html-taghandler">on this SO question</a>:

<pre><code>Spanned parsed = Html.fromHtml(PageText, null, new MyHtmlTagHandler());
</code></pre>

And the <code>TagHandler</code> implements the methods:

<pre><code>public void handleTag(boolean opening, String tag, Editable output,
 XMLReader xmlReader) {
 if(tag.equalsIgnoreCase("strike") || tag.equals("s")) {
 processStrike(opening, output);
 }
}
....
</code></pre>

blocks|key|2335222|text|我们工作的大多数应用程序都会在整个项目中使用文本，谢天谢地，KTX在涉及到这些部分时提供了一些扩展函数。对于文本，我们基本上有一些可用于SpannableStringBuilder类的函数。例如，在实例化一个Builder实例之后，我们可以使用build方法来追加一些粗体文本：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2335223|+textView.text+=buildSpannedString+{
++++++++strikeThrough+{
++++++++++++append(
++++++++++++++++value+?:+""
++++++++++++)
++++++++}

Most of the applications we work in are going to use text somewhere throughout the project and thankfully, KTX provides some extension functions when it comes to these parts. For text, we essentially have some functions available for the SpannableStringBuilder class.
For example, after instantiating a Builder instance we can use the build methods to append some bold text:
<pre><code> textView.text =buildSpannedString {
 strikeThrough {
 append(
 value ?: &quot;&quot;
 )
 }
 }
</code></pre>

I have a block of text coming from a webservice, and depending on some tags which I have predefined, I want to style the text before setting it to my TextView. For bold, italics, and underline, I was able to do this easily with the replaceAll command:

<pre><code>PageText = PageText.replaceAll("\\*([a-zA-Z0-9]+)\\*", "&lt;b&gt;$1&lt;/b&gt;");
 PageText = PageText.replaceAll("=([a-zA-Z0-9]+)=", "&lt;i&gt;$1&lt;/i&gt;"); 
 PageText = PageText.replaceAll("_([a-zA-Z0-9]+)_", "&lt;u&gt;$1&lt;/u&gt;");
txtPage.setText(Html.fromHtml(PageText), TextView.BufferType.SPANNABLE);
</code></pre>

So, to bold a word, surround it with *'s, for italics, surround with _.

But, for strikethrough, Html.fromHtml does not support the "strike" tag, so it can't be done this same way. I've seen examples of using Spannable to set the styling on one section of text, but it requires positional numbers. So, I guess I could loop through the text, searching for - (the tag to represent the strike), then searching for the next one, spanning the text in between, and repeating for all such strings. It will end up being 10 lines of looping code as opposed to 1 for the others, so I'm wondering if there is a more elegant solution out there.
