How to remove or remove html tags in Android

Question

PHP has a strip_tags function that removes HTML and PHP tags from a string.

Does Android have a way to avoid html?

Answer 1

The solutions in the answer related to @sparkymat usually require either a regular expression that is prone to approach errors or the installation of a third-party library such as jsoup or jericho . The best solution for Android devices is to use the Html.fromHtml () function:

 public String stripHtml(String html) { if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) { return Html.fromHtml(html, Html.FROM_HTML_MODE_LEGACY); } else { return Html.fromHtml(html); } } 

This uses the Android built-in Html parser to create a Spanned view of the input html without any html tags. The Span markup is then removed by converting the output back to a string.

As discussed here , the behavior of Html.fromHtml has changed from Android N. See the documentation for more information.

Alternatively, you can use Html.escapeHtml(String) if you are targeting API 16 or higher.

For targeting below API 16, you can instead use the following class by calling HtmlUtils.escapeHtml(String) , which I just pulled from the source Html.escapeHtml(String) .

 public class HtmlUtils { public static String escapeHtml(CharSequence text) { StringBuilder out = new StringBuilder(); withinStyle(out, text, 0, text.length()); return out.toString(); } private static void withinStyle(StringBuilder out, CharSequence text, int start, int end) { for (int i = start; i < end; i++) { char c = text.charAt(i); if (c == '<') { out.append("&lt;"); } else if (c == '>') { out.append("&gt;"); } else if (c == '&') { out.append("&amp;"); } else if (c >= 0xD800 && c <= 0xDFFF) { if (c < 0xDC00 && i + 1 < end) { char d = text.charAt(i + 1); if (d >= 0xDC00 && d <= 0xDFFF) { i++; int codepoint = 0x010000 | (int) c - 0xD800 << 10 | (int) d - 0xDC00; out.append("&#").append(codepoint).append(";"); } } } else if (c > 0x7E || c < ' ') { out.append("&#").append((int) c).append(";"); } else if (c == ' ') { while (i + 1 < end && text.charAt(i + 1) == ' ') { out.append("&nbsp;"); i++; } out.append(' '); } else { out.append(c); } } } } 

I am using this class that works great.

Sorry for posting late, but I think this may help others,

To just remove the html bands

 Html.fromHtml(htmltext).toString() 

Thus, the html tag will be replaced with a string, but the string will not be formatted properly. Therefore i did

 Html.fromHtml(htmltext).toString().replaceAll("\n", "").trim() 

Thus, I first replace the next line with a space and remove the empty space. Similarly, you can remove others.

This is for a new method alternative (API 16 +):

 android.text.Html.escapeHtml(your_html).toString(); 

Answer 5

  Spanned spanned; if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) { spanned = Html.fromHtml(textToShare, Html.FROM_HTML_MODE_LEGACY); } else { spanned = Html.fromHtml(textToShare); } tv.setText(spanned.toString()); 

Answer 6

It's dead just with jsoup

 public static String html2text(String html) { return Jsoup.parse(html).text(); }
