无法显示HTML字符串
我在Android WebView中苦于显示字符串HTML。 在服务器端，我下载了一个网页并转义HTML字符和引号（我使用Python）：
my_string = html.escape(my_string, True)
在Android客户端：字符串未被转义：
myString = StringEscapeUtils.unescapeHtml4(myString)
webview.loadData( myString, "text/html", "encoding");
然而，webview只是将它们显示为文字字符串。 结果如下： 
编辑：我添加从服务器端返回的原始字符串：

Jerry Brown Says Ted Cruz Is &#39;Absolutely Unfit&#39; To Run For Office Because Of Climate Change Views</a></h2> <h4>Sam Levine</h4> <div class="article"> <p>California Gov. Jerry Brown (D) said on Sunday that Texas Sen. Ted Cruz (R-Texas) is "absolutely unfit to be running for office" because of his position on climate change.</p> <p>"I just came back from New Hampshire, where there's snow and ice everywhere. My view on this is simple: Debates on this should follow science and should follow data, and many of the alarmists on global warming, they have a problem because the science doesn't back them up," Cruz <a href="https://www.youtube.com/watch?v=m0UJ_Sc0Udk">said</a> on "Late Night with Seth Meyers" last week.</p> <p>To back up his claim, Cruz cited satellite data that has shown a lack of significant warming over the last 17 years. But Cruz's reasoning <a href="http://www.politifact.com/truth-o-meter/statements/2015/mar/20 /ted-cruz/ted-cruzs-worlds-fire-not-last-17-years/">has been debunked by Politifact</a>, which has shown that scientists have ample evidence to believe that the climate will continue to warm.</p> <p>"What he said is absolutely false,” Brown said on <a href="http://www.nbcnews.com/meet-the-press/california-governor-ted-cruz- unfit-be-running-n328046">NBC's "Meet the Press."</a> He added that <a href="http://climate.nasa.gov/scientific-consensus/">over 90 percent</a> of scientists who study the climate agree that climate change is caused by human activity. "That man betokens such a level of ignorance and a direct falsification of existing scientific data. It's shocking, and I think that man has rendered himself absolutely unfit to be running for office," Brown said.</p> <p>Brown added that climate change has <a href="http://www.huffingtonpost.com/2015/03/06/california-drought-february- record_n_6820704.html?utm_hp_ref=california-drought">caused droughts in his state</a>, as well as severe cold and storms on the east coast.</p> <p>While Cruz may have seen snow and ice everywhere in New Hampshire, data shows that the country is actually experiencing a <a href="http://www.huffingtonpost.com/2015/02/19/cold-weather- winter_n_6713104.html">warmer than average</a> winter.</p> <p>Brown’s criticism of Cruz comes one day before the Texas senator is set to announce a <a href="http://www.huffingtonpost.com/2015/03/22 /ted-cruz-2016_n_6917824.html">presidential campaign</a>. </p> </div> <div class="original"> <a href="http://www.huffingtonpost.com/2015/03/22/ted-cruz-climate-change_n_6919002.html">VIEW ORIGINAL</a> </div> </div> </div> </div> <script src="//code.jquery.com/jquery-latest.js"></script> <script src="/static/js/modal.js"></script> <script src="/static/js/bootbox.min.js"></script> <script src="/static/js/site.js"></script> <script> (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('create', 'UA-56257533-1', 'auto'); ga('send', 'pageview'); </script> </body> </html>";

尝试这个：

String s = "You HTML string";
wv.loadData(stripHtml(s), "text/html", "UTF-8");
public String stripHtml(String html) {

试试这个代码，
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N){
yourtextview.setText(Html.fromHtml(yourstring,Html.FROM_HTML_MODE_LEGACY));
}
else {
yourtextview.setText(Html.fromHtml(yourstring));
}
