As Per Your Code i thought you don't set following setting Webviewclient and Webcromeclient to enable Javascript in Webview.

 mWebView.setWebViewClient(new WebViewClient());

 mWebView.setWebChromeClient(new WebChromeClient());

Then you load your Html page with following code.

 mWebView.loadUrl(file:///android_asset/+Your_Html_Page);

And This is Html part in your Webview.

<!DOCTYPE html>

<html>

<head>

    <script>

    function myFunction()

    {

        alert(Hello! I am an alert box!);

    }

    </script>

</head>

<body>



<input type=button onclick=myFunction() value=Show alert box />

</body>

</html>

try this might be helpful.
