WebSettings webSettings = wv.getSettings();

webSettings.setJavaScriptEnabled(true);
   
wv.loadUrl("http://www.meusite.com.br");

Por padrão javascript é desabilitado na webview.

http://developer.android.com/guide/webapps/webview.html

Enabling JavaScript

JavaScript is disabled in a WebView by default. You can enable it through the WebSettings attached to your WebView. You can retrieve WebSettings with getSettings(), then enable JavaScript with setJavaScriptEnabled().

For example:

WebView myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);

WebSettings provides access to a variety of other settings that you might find useful. For example, if you're developing a web application that's designed specifically for the WebView in your Android application, then you can define a custom user agent string with setUserAgentString(), then query the custom user agent in your web page to verify that the client requesting your web page is actually your Android application.

import android.view.ViewGroup.LayoutParams;

import android.webkit.WebView;

import android.webkit.WebViewClient;

public class MainActivity extends Activity {

    

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        

        final ProgressBar pb = new ProgressBar(this);

        FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

        lp.gravity = Gravity.CENTER;

        pb.setLayoutParams(lp);

        

        final FrameLayout fl = (FrameLayout) findViewById(R.id.frameLayout);

        

        final WebView wv = (WebView) findViewById(R.id.webView);

        wv.loadUrl("http://www.meusite.com.br");

    

    

        wv.setWebViewClient(new WebViewClient(){

            @Override

            public void onPageStarted(WebView view, String url, Bitmap favicon){

                /*ProgressBar pb = (ProgressBar) findViewById(R.id.progress);

                pb.setVisibility(View.VISIBLE);*/

                fl.addView(pb);

            }

            

            @Override

            public void onPageFinished(WebView view, String url){

                //ProgressBar pb = (ProgressBar) findViewById(R.id.progress);

                //pb.setVisibility(View.INVISIBLE);

                fl.removeView(pb);

                wv.setVisibility(View.VISIBLE);

            }

        });

    }

}

Obrigado a todos
