Since there is limitation, I cant change any code from native side. I want to do it only through my web application using javascript. – JustCode Mar 21 '18 at 10:29
What limitation? do you have the access to the ImageView in your native code? if so you can disable it. if you don't have the Id of the imageView so there is no way possible for change it's state – Amine ABDALKHALKI Mar 21 '18 at 10:33
Amine ABDALKHALKI - i cant change any code in native but i know the id of ImageButton. All i want is without changing any code in native, i want to disable the Imagebutton from my javascript – JustCode Mar 21 '18 at 10:53
from Javascript you can't change a "thing" without calling a native code.. i hope it's clear for you – Amine ABDALKHALKI Mar 21 '18 at 11:03

Try to set webviewclient to your webview and override onPageFinished like this. In my project I tried to hide google and facebook buttons on fitbit page.

    webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                if (!TextUtils.isEmpty(url) && url.contains("fitbit")) {
                    view.loadUrl("javascript: setTimeout(function () { $('.external-choices,.or').hide();} , 1000) ");//JS to hide the fitbit login from G+ and FB
                }
            }
}

Could you please post screenshot, if you are trying to hide action bar can't you set the theme of that activity which holds your webview accordingly – Ravi Mar 22 '18 at 10:20
