将任何变量值从Java传递到JavaScript

Question

I'm using a webview in my android application, and the web address that the webview loads contains some JavaScript. Now, I just want to know if it is possible to pass in some variable values from my Java Code to my JavaScript.

Here's my code:

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.map_layout);
    webView = (WebView) findViewById (R.id.webview);
    WebSettings webViewSettings = webView.getSettings();
    webViewSettings.setJavaScriptEnabled(true);
    webView.addJavascriptInterface(new transferPlaceId(), "Android");
    webView.loadUrl("http://webaddress.com/directory/page.html");

}

Javascript Interface works well, no need to worry about it. Any help will be much appreciated. Thanks in advance!

Yes, you can

String name = "foo";
webView.loadUrl("javascript:functionName('"+name+"')");
