Cannot display HTML string
AndroidPythonHtmlWebviewAndroid Problem Overview
I am struggling with display string HTML in Android WebView.
On the server side, I downloaded a web page and escape HTML characters and quotes (I used Python):
my_string = html.escape(my_string, True)
On the Android client side: strings are unescaped by:
myString = StringEscapeUtils.unescapeHtml4(myString)
webview.loadData( myString, "text/html", "encoding");
However webview just display them as literal strings. Here are the result:
Edit: I add original string returned from server side:

Solution 2 - Android
Try this code,
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));
}
Solution 3 - Android
Try this:
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();
}
