android studio No se puede mostrar la cadena HTML




meta title y meta descripcion (3)

Estoy luchando con mostrar la cadena HTML en Android WebView. En el lado del servidor, descargué una página web y escapé de caracteres y citas HTML (usé Python):

my_string = html.escape(my_string, True)

En el lado del cliente de Android: las cadenas no se escapan por:

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

Sin embargo, webview solo los muestra como cadenas literales. Aquí están los resultados:

Edición: agrego una cadena original devuelta desde el lado del servidor:

Prueba esto:

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();
}

Prueba este código,

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));
}

He modificado el código aquí:

public class test extends Activity {
private WebView wv;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test);
    wv = (WebView) findViewById(R.id.wv);
