无法显示HTML字符串


98

我正在Android WebView中使用显示字符串HTML挣扎。

在服务器端,我下载了一个网页并转义了HTML字符和引号(我使用了Python):

my_string = html.escape(my_string, True)

在Android客户端上:字符串不通过以下方式转义:

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

但是,webview只是将它们显示为文字字符串。结果如下:

在此处输入图片说明

编辑:我添加从服务器端返回的原始字符串:

链接rel =“ apple-touch-icon”;尺寸=“ 114x114” href =“&quot; /static/favicon/apple-touch-icon-114x114.png”&gt; &lt; link rel =“苹果触摸图标”;尺寸=“ 72x72” href =“&quot; /static/favicon/apple-touch-icon-72x72.png”&gt; &lt; link rel =“苹果触摸图标”;尺寸=“ 144x144” href =“&quot; /static/favicon/apple-touch-icon-144x144.png”&gt; &lt; link rel =“苹果触摸图标”;尺寸=“ 60x60” href =“&quot; /static/favicon/apple-touch-icon-60x60.png”&gt; &lt; link rel =“苹果触摸图标”;尺寸=“ 120x120” href =“&quot; /static/favicon/apple-touch-icon-120x120.png”&gt; &lt; link rel =&quot; 苹果触摸图标” 尺寸=“ 76x76” href =“&quot; /static/favicon/apple-touch-icon-76x76.png”&gt; &lt; link rel =“苹果触摸图标”;尺寸=“ 152x152” href =“&quot; /static/favicon/apple-touch-icon-152x152.png”&gt; &lt; link rel =“苹果触摸图标”;尺寸=“ 180x180” href =“&quot; /static/favicon/apple-touch-icon-180x180.png”&gt; &lt; link rel =“ icon”;type =“ image / png” href =“&quot; /static/favicon/favicon-192x192.png” 尺寸=“ 192x192” &lt; link rel =“ icon”;type =“ image / png” href =“&quot; /static/favicon/favicon-160x160.png” 尺寸=“ 160x160” &lt; link rel =&quot; 图标” type =“ image / png” href =“&quot; /static/favicon/favicon-96x96.png” 尺寸=“ 96x96” &lt; link rel =“ icon”;type =“ image / png” href =“&quot; /static/favicon/favicon-16x16.png” 尺寸=“ 16x16” &lt; link rel =“ icon”;type =“ image / png” href =“&quot; /static/favicon/favicon-32x32.png” 尺寸=“ 32x32” &lt;元名称=“ msapplication-TileColor”;内容=“#da532c” &lt;元名称=“ msapplication-TileImage”;content =“ / static / favicon / mstile-144x144.png” &lt;元名称=“ msapplication-config”;内容=“ / static / favicon / browserconfig.xml”;&gt; &lt;!-外部CSS-&gt; &lt; link rel =“ stylesheet” href =&quot;https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css&quot; &lt;!-外部字体-&gt; &lt; link href =” // maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css” rel =“ stylesheet” &lt; link href =&#x27; // fonts.googleapis.com/css?family=Open+Sans:300,600' rel =&#x27; stylesheet&#x27; type =&#x27; text / css&#x27;&gt; &lt; link href =&#x27; // fonts.googleapis.com/css?family=Lora:400,700' rel =&#x27; stylesheet&#x27; type =&#x27; text / css&#x27;&gt; &lt;!-[如果是IE 9]&gt; &lt; script src =” // cdnjs.cloudflare.com/ajax/libs/html5shiv/3.7.2/html5shiv.min.js”</script> &lt; script src =” // cdnjs.cloudflare.com/ajax/libs/respond.js/1.4.2/respond.min.js”&lt; / script&gt; &lt ;!

Jerry Brown Says Ted Cruz Is &amp;#39;Absolutely Unfit&amp;#39; To Run For Office Because Of Climate Change Views&lt;/a&gt;&lt;/h2&gt; &lt;h4&gt;Sam Levine&lt;/h4&gt; &lt;div class=&quot;article&quot;&gt; &lt;p&gt;California Gov. Jerry Brown (D) said on Sunday that Texas Sen. Ted Cruz (R-Texas) is &quot;absolutely unfit to be running for office&quot; because of his position on climate change.&lt;/p&gt; &lt;p&gt;&quot;I just came back from New Hampshire, where there&#x27;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&#x27;t back them up,&quot; Cruz &lt;a href=&quot;https://www.youtube.com/watch?v=m0UJ_Sc0Udk&quot;&gt;said&lt;/a&gt; on &quot;Late Night with Seth Meyers&quot; last week.&lt;/p&gt; &lt;p&gt;To back up his claim, Cruz cited satellite data that has shown a lack of significant warming over the last 17 years. But Cruz&#x27;s reasoning &lt;a href=&quot;http://www.politifact.com/truth-o-meter/statements/2015/mar/20 /ted-cruz/ted-cruzs-worlds-fire-not-last-17-years/&quot;&gt;has been debunked by Politifact&lt;/a&gt;, which has shown that scientists have ample evidence to believe that the climate will continue to warm.&lt;/p&gt; &lt;p&gt;&quot;What he said is absolutely false,” Brown said on &lt;a href=&quot;http://www.nbcnews.com/meet-the-press/california-governor-ted-cruz- unfit-be-running-n328046&quot;&gt;NBC&#x27;s &quot;Meet the Press.&quot;&lt;/a&gt; He added that &lt;a href=&quot;http://climate.nasa.gov/scientific-consensus/&quot;&gt;over 90 percent&lt;/a&gt; of scientists who study the climate agree that climate change is caused by human activity. &quot;That man betokens such a level of ignorance and a direct falsification of existing scientific data. It&#x27;s shocking, and I think that man has rendered himself absolutely unfit to be running for office,&quot; Brown said.&lt;/p&gt; &lt;p&gt;Brown added that climate change has &lt;a href=&quot;http://www.huffingtonpost.com/2015/03/06/california-drought-february- record_n_6820704.html?utm_hp_ref=california-drought&quot;&gt;caused droughts in his state&lt;/a&gt;, as well as severe cold and storms on the east coast.&lt;/p&gt; &lt;p&gt;While Cruz may have seen snow and ice everywhere in New Hampshire, data shows that the country is actually experiencing a &lt;a href=&quot;http://www.huffingtonpost.com/2015/02/19/cold-weather- winter_n_6713104.html&quot;&gt;warmer than average&lt;/a&gt; winter.&lt;/p&gt; &lt;p&gt;Brown’s criticism of Cruz comes one day before the Texas senator is set to announce a &lt;a href=&quot;http://www.huffingtonpost.com/2015/03/22 /ted-cruz-2016_n_6917824.html&quot;&gt;presidential campaign&lt;/a&gt;. &lt;/p&gt; &lt;/div&gt; &lt;div class=&quot;original&quot;&gt; &lt;a href=&quot;http://www.huffingtonpost.com/2015/03/22/ted-cruz-climate-change_n_6919002.html&quot;&gt;VIEW ORIGINAL&lt;/a&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;script src=&quot;//code.jquery.com/jquery-latest.js&quot;&gt;&lt;/script&gt; &lt;script src=&quot;/static/js/modal.js&quot;&gt;&lt;/script&gt; &lt;script src=&quot;/static/js/bootbox.min.js&quot;&gt;&lt;/script&gt; &lt;script src=&quot;/static/js/site.js&quot;&gt;&lt;/script&gt; &lt;script&gt; (function(i,s,o,g,r,a,m){i[&#x27;GoogleAnalyticsObject&#x27;]=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,&#x27;script&#x27;,&#x27;//www.google-analytics.com/analytics.js&#x27;,&#x27;ga&#x27;); ga(&#x27;create&#x27;, &#x27;UA-56257533-1&#x27;, &#x27;auto&#x27;); ga(&#x27;send&#x27;, &#x27;pageview&#x27;); &lt;/script&gt; &lt;/body&gt; &lt;/html&gt;";

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));
}

试试这个:

wv = (WebView) findViewById(R.id.wv);
String s = "You HTML string";
wv.loadData(stripHtml(s), "text/html", "UTF-8");

public String stripHtml(String html) {
    return Html.fromHtml(html).toString();
}
