Android Question Disabel Virtual Kayboard with WebView

Hi All,
this is my first post, so I do apologize if I am making anything wrong...

question is how to avoid that the virtual keyboard be shown whenever a HTLM textBox inside the Webview gets the focus. I have tried:

1. SetActivityAttribute(main, android:windowSoftInputMode, adjustResize|stateHidden) but it didn't work in my case. (question in https://www.b4x.com/android/forum/threads/how-do-i-disable-keyboard-for-webview.48264/#content)
2. Use IME to hide it, but the problem here is that the keyboard is shown and then after hidden causing an effect that is not accepted by customer

I have searched in forum and no anwser solved my problem. Any help would be pretty much appreciated.

Thanks
