Impossibile visualizzare la stringa HTML

Question

Sto lottando con la stringa di visualizzazione HTML in Android WebView.

Sul lato server, ho scaricato una pagina web ed esegui l'escape di caratteri HTML e virgolette (ho usato Python):

my_string = html.escape(my_string, True)

Sul lato client Android: le stringhe sono senza caratteri di escape:

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

Tuttavia webview li visualizza solo come stringhe letterali. Ecco il risultato:

Modifica: aggiungo la stringa originale restituita dal lato server:

"& lt;! DOCTYPE html & gt; & lt; html lang = & quot; en & quot; & gt; & lt; head & gt; & lt; meta charset = & quot; utf-8 & quot; & gt; & lt; meta http-equiv = & quot; X-UA-Compatible & quot; content = & quot; IE = edge & quot; & gt; & lt; meta name = & quot; viewport & quot; content = & quot; width = device-width, initial-scale = 1.0 & quot; & gt; & lt; meta name = & quot; description & quot; content = & quot ; & quot; & gt; & lt; title & gt; Saulify & lt; / title & gt; & lt;! - Tutte le favicon ... - & gt; & lt; link rel = & quot; shortcut icon & quot; href = & quot; / static / favicon / favicon. ico & quot; & gt; & lt; link rel = & quot; apple-touch-icon & quot ;izes = & quot; 57x57 & quot; href = & quot; /static/favicon/apple-touch-icon-57x57.png" & gt; & lt; link rel = & quot ; apple-touch-icon & quot ;izes = & quot; 114x114 & quot; href = & quot; /static/favicon/apple-touch-icon-114x114.png" & gt; & lt; link rel = & quot; apple-touch-icon & quot; sizes = & quot ; 72x72 & quot; href = & quot; /static/favicon/apple-touch-icon-72x72.png" & gt; & lt; link rel = & quot; apple-touch-icon & quot; sizes = & quot; 144x144 & quot; href = & quot; / static / favicon / apple -touch-icon-144x144.png & quot; & gt; & lt; link rel = & quot; apple-touch-icon & quot; dimensioni = & quot; 60 x 60 & quot; href = & quot; /static/favicon/apple-touch-icon-60x60.png" & gt; & lt; link rel = & quot; apple-touch-icon & quot; dimensioni = & quot; 120x120 & quot; href = & quot; /static/favicon/apple-touch-icon-120x120.png" & gt; & lt; link rel = & quot; apple-touch-icon & quot; dimensioni = & quot; 76 x 76 & quot; href = & quot; /static/favicon/apple-touch-icon-76x76.png" & gt; & lt; link rel = & quot; apple-touch-icon & quot; dimensioni = & quot; 152 x 152 & quot; href = & quot; /static/favicon/apple-touch-icon-152x152.png" & gt; & lt; link rel = & quot; apple-touch-icon & quot; dimensioni = & quot; 180x180 & quot; href = & quot; /static/favicon/apple-touch-icon-180x180.png" & gt; & lt; link rel = & quot; icon & quot; type = & quot; image / png & quot; href = & quot; /static/favicon/favicon-192x192.png" dimensioni = & quot; 192 x 192 & quot; & gt; & lt; link rel = & quot; icon & quot; type = & quot; image / png & quot; href = & quot; /static/favicon/favicon-160x160.png" dimensioni = & quot; 160x160 & quot; & gt; & lt; link rel = & quot; icon & quot; type = & quot; image / png & quot; href = & quot; /static/favicon/favicon-96x96.png" dimensioni = & quot; 96 x 96 & quot; & gt; & lt; link rel = & quot; icon & quot; type = & quot; image / png & quot; href = & quot; /static/favicon/favicon-16x16.png" dimensioni = & quot; 16 x 16 & quot; & gt; & lt; link rel = & quot; icon & quot; type = & quot; image / png & quot; href = & quot; /static/favicon/favicon-32x32.png" dimensioni = & quot; 32 x 32 & quot; & gt; & lt; meta name = & quot; msapplication-TileColor & quot; content = & quot; # da532c & quot; & gt; & lt; meta name = & quot; msapplication-TileImage & quot; content = & quot; /static/favicon/mstile-144x144.png" & gt; & lt; meta name = & quot; msapplication-config & quot; content = & quot; /static/favicon/browserconfig.xml" & gt; & lt;! - CSS esterno - & gt; & lt; link rel = & quot; foglio di stile & quot; href = & quot;https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css & quot; & gt; & lt;! - Caratteri esterni - & gt; & lt; link href = & quot; // maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css" rel = & quot; foglio di stile & quot; & gt; & lt; link href = & # x27; // fonts.googleapis.com/css?family=Open+Sans:300,600' rel = & # x27; foglio di stile & # x27; tipo = & # x27; testo / css & # x27; & gt; & lt; link href = & # x27; // fonts.googleapis.com/css?family=Lora:400,700' rel = & # x27; foglio di stile & # x27; tipo = & # x27; text / css & # x27; & gt; & lt;! - [if lt IE 9] & gt; & lt; script src = & quot; // cdnjs.cloudflare.com/ajax/libs/html5shiv/3.7.2/html5shiv.min.js"></script> & lt; script src = & quot; // cdnjs.cloudflare.com/ajax/libs/respond.js/1.4.2/respond.min.js"></script> & lt;!

Answer 1

Ho modificato il codice qui:

public class test extends Activity {
    private WebView wv;

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.test);
        wv = (WebView) findViewById(R.id.wv);

        wv.loadData(stripHtml(s), "text/html", "UTF-8");

    }

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

}

Answer 2

Prova questo codice,

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));
}

Answer 3

Prova questo:

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();
}
