关于Android：无法显示HTML字符串

Cannot display HTML string

在Android WebView中，我正在努力处理显示字符串HTML。在服务器端，我下载了一个网页并转义HTML字符和引号(我使用了python)：

1	my_string = html.escape(my_string, True)

在Android客户端：字符串不受以下条件限制：

1 2	myString = StringEscapeUtils.unescapeHtml4(myString) webview.loadData( myString,"text/html","encoding");

然而，WebView只是将它们显示为文本字符串。结果如下： enter image description here

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

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
