I recommend you to create a javascript function like :

function login(NAME, PASS)
{
    document.getElementById('horde_user').value=pass;
    document.getElementById('horde_pass').value=id;
    document.getElementsByName('login_button')[0].click();
}

And then from your app code

String id = "myid"; //Get val from the dialog
String pass = "mypass"; //Get val from the dialog
webview.loadUrl("javascript:login('"+NAME+"','"+PASS+"')");

if you need call java from js you can folow this post Hope it helps ;)
