Question

I have seen this question floating around the internet, but I haven’t found a working solution yet. Basically, I want to load my app and press a button; the button action will then fill in a username and password in a website already loaded in the webview (or wait for onPageFinished). Finally, the submit button on the login page will be activated.

From what I understand this can be done by doing a java injection with the loadUrl(javascript), but I don’t know what the java commands would be to fill in the fields. The same question was asked for iOS, but the commands are slightly different.

Is it possible to do what I am asking with javascript in a webivew, or do I have to do a http-post without a webview like this or this?

Thank you so much for any help you can give!

You don’t need to use “java commands”… but instead JavaScript… for instance:

String username = "cristian";
webview.loadUrl("javascript:document.getElementById('username').value = '"+username+"';");

So basically, what you have to do is a big string of JavaScript code that will get those fields and put values on them; also, you can enable/disable the submit button from JavaScript.
