Is there anyway to modify the alert box title? Any help will be greatly appreciated. :)

Answer 1

There are 3 types of js alerts:

• alert box - with an Ok button to proceed.
• confirm box - with both OK and cancel button.
• prompt box - get a value from the user and then select OK/Cancel.

---

• Use onJsAlert for alertBox .
• Use onJsConfirm for confirmBox .
• Use onJsPrompt for promptBox

I have added the sample code for onJsConfirm,

        webViewLayout.setWebChromeClient(new WebChromeClient(){
        @Override
        public boolean onJsConfirm(WebView view, String url, String message, final JsResult result) {

            AlertDialog dialog =new AlertDialog.Builder(view.getContext()).
                    setTitle("Confirm").
                    setIcon(ContextCompat.getDrawable(view.getContext(),R.drawable.image)).
                    setMessage(message).
                    setNegativeButton("No", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            result.cancel();
                        }
                    }).
                    setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            FlashMessage("JS");
                            result.confirm();
                        }
                    })
                    .create();
            dialog.show();
            return true;
        }
    });
