How to Programmatically Enter form input fields in WebView, then click submit?

I don't have any problem parsing WebView HTML or loading URLs (relative or absolute) but I am stumped as to how to programmatically "simulate" the user entering username & password, then clicking the submit/login button, given the following HTML:

<form method="post" class="mobile-login-form" id="login_form" action="https://www.example.com/login.php?m=m&amp;refsrc=http%3A%2F%2Fm.example.com%2F&amp;refid=0">
  <input type="hidden" name="lsd" autocomplete="off">
  <input type="hidden" name="post_form_id" value="1b3cf017c90d483cc50fcac3f2a9a283">
  <input type="hidden" name="charset_test" value="€,´,€,´,?,?,?">
  <input type="hidden" name="version" value="1">
  <input type="hidden" id="ajax" name="ajax" value="1">
  <input type="hidden" id="width" name="width" value="313">
  <input type="hidden" id="pxr" name="pxr" value="1.5">
  <input type="hidden" id="gps" name="gps" value="1">
  <div class="bgx msf" data-sigil="intfs">
    <div class="mfss fcg">Username:
    </div>
    <input class="input mobile-login-field" name="username" value="" type="text">
  </div>
  <div class="bgx msf" data-sigil="intfs">
    <div class="mfss fcg">Password:
    </div>
    <input class="input mobile-login-field" autocorrect="off" autocapitalize="off" name="pass" type="password">
  </div>
  <div class="bgx msf" data-sigil="intfs">
    <label class="btn btnC touchable" data-sigil="blocking-touchable">
      <input type="submit" value="Log In" class="mfss" name="login">
    </label>
  </div>
</form>

(I don't control that HTML, this is just an example for an arbitrary website prompt)

I don't need to do so called "silent authentication" - I merely want to provide a convenience shortcut for the user clicking a button instead of re-typing username & password over and over again (in case, clear cache or clear data were performed).

Define JS function within your html page and call it with following method.

 private void callJavaScriptFunction(String functionName, List<String> params) {
            String javaScript = "javascript:";

        javaScript += functionName + " ( ";

        if (params != null) {
                for(int i = 0; i < params.size(); i++) {
                        javaScript += params.get(i);

                        if (i != params.size() - 1) {
                                javaScript += ", ";
                        }
                }
        }

        javaScript += ");";

        Log.d(javaScript);

        webView.loadUrl(javaScript);
}

Have you tried using monkey tools. Should be able to do that task.
