you need to develop web service at server side and from webservice you can redirect directly login page in webview — Adil, Feb 26 '18 at 11:09
Bro I want to enter username and password programmatically in webview page — Dinesh S, Feb 26 '18 at 11:16
So do you want to populate username and password and submit it automatically (without any user intervention)? — Varad Mondkar, Feb 26 '18 at 11:42
Hey @DineshS did you find out the solution to this? Even I am trying to login to a website but not happening. — abhishek maharajpet, Mar 08 '19 at 09:33

step 1) first of all enable javascript in your webview

step 2) on onPageFinished using javascript autofill username and password field and generate click on login button

wv.loadUrl("javascript:document.getElementsByName('Username').value = 'abc'");
wv.loadUrl("javascript:document.getElementsByName('Pass').value = 'xyz'");
wv.loadUrl("javascript:document.forms['Login'].submit()");

This did not work for me. It showed a blank while screen with my username. my username should actually be seen in the username field – abhishek maharajpet Mar 08 '19 at 09:31

This explanation helped me. Fill form in WebView with Javascript

view.evaluateJavascript(js, new ValueCallback<String>() {
                @Override
                public void onReceiveValue(String s) {
                }

instead of

view.loadUrl(js);

which is the answer I found everywhere else.
