You should use HttpUtils2 to send a POST request.

Hi Erel!
thanks for your kind and fast answer.
Yes I know and use HttpUtils2 to send POST requests but in this case the answer that I receive from the server is a web page dinamically created based on the POST value and need to show it in a webview.
I have seen that the webview for android has a postUrl method and I wonder if it possible to simulate it with the B4A version.
Perhaps it is possible to combine both (webview and httputils) but i don't know how.
Anyway if it is not possible thanks for your great software.

WebView will create a post request when the user presses on a submit button of a POST form.

Yes I understand that webview works like a browser and can send a POST submit from a form but the problem I have here is there is not a form that interacts with the user. The server side code receives the POST requests directly by means of ajax and I have no access to modify that PHP.
Perhaps the easier solution would be to create an intermediate web page with a form (or javascript and ajax) and open it in the webview instead of connecting directly.

Well, anyway thanks for your support.

Despite this being an old question I was just trying to find out how to do the same sort of thing, that is craft an HTTP request and then POST it using Webview. ( Sometimes using HttpUtils2 is not going to be a solution to this problem if you already have an app using Webview).

This is a very simple way of creating a POST request and then sending it using Webview. Basically it creates a form on the fly and then using the submit-on-load option to post it.

B4X: 
            dim Webview1 as Webview
            Dim html = $"<!DOCTYPE html>
            <html>"
            <body onload='document.frm1.submit()'>
            <form action='yoururl' method='post' name='frm1'>
              <input Type='hidden' name='param1' value='v1><br>
              <input Type='hidden' name='param2' value='v2><br>
              <input Type='hidden' name='param3' value='v3><br>
            
            </form>
            </body>
            </html>"$
            WebView1.LoadHtml(html)

Thanks to kmchmk on Stack Overflow for this idea in response to this question How to post data for WebView android
