passing value to webview from an activity in andro

问题:

I have one activity to produce some result respect with user input.

my xml page is like one text view, button and a webview.

when user input some date and clicks the button then generate one value. also when loading page the web view loads a local html page from asset folder and its showing some default value.

what my need is when new value generates respect with button click i need to change the html pages value also.

How to I pass value to web view. pblm is I don't want to pass value to while loading I need to pass value at some intermediate stage because default its already showing one value.

how to make this. I appreciate it if anyone can help.

You can have validation by using integer and boolean depending on user's event and load the local html file from assert like

webview.loadUrl("file:///android_asset/aboutcertified.html");
