android webview客户端活动指标

我在Webview中获得了显示活动指标的代码.我检查了多个参考,但仍然无法使其正常工作.你能帮我下面调试我的代码吗？

活动指标不在下面的代码

protected void onCreate(Bundle savedInstanceState) {
    // Todo Auto-generated method stub
    super.onCreate(savedInstanceState);
    this.getwindow().requestFeature(Window.FEATURE_PROGRESS);
    final BaseActivity MyActivity = ReviewWebActivity.this;
    setContentView(R.layout.review_web);
    getwindow().setFeatureInt(Window.FEATURE_PROGRESS,Window.PROGRESS_VISIBILITY_ON);


    ScannedProduct product =  getReviewUrl();
    reviewUrl = product.getReviewLink();

    if (reviewUrl == null) {
        String err = product.getErrorCode();
        if(err.equals("")) err ="No Data Available for this product";
        Toast.makeText(getApplicationContext(),"No Data Available for this product",1).show();
        return;
    }

    webReview = (WebView) findViewById(R.id.webReview);
    webReview.setWebChromeClient(new WebChromeClient() {
        public void onProgressChanged(WebView view,int progress) {
            // Make the bar disappear after URL is loaded,and changes
            // string to Loading...
            MyActivity.setTitle("Loading...");
            MyActivity.setProgress(progress * 1000); // tried with 100 also


        }
    });
    webReview.setWebViewClient(new ReviewWebClient());
    webReview.getSettings().setJavaScriptEnabled(true);

    webReview.loadUrl(reviewUrl);
}

解决方法

import android.app.Activity;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class SandbarinFacebook extends Activity {
    WebView mWebView;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        final ProgressDialog pd = ProgressDialog.show(this,"","Loading...",true);

        mWebView = (WebView) findViewById(R.id.webkitWebView1);
        mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.getSettings().setSupportZoom(true);  
        mWebView.getSettings().setBuiltInZoomControls(true);
        mWebView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view,String url) {
                if(pd!=null && pd.isShowing())
                {
                    pd.dismiss();
                }
            }
        });
        mWebView.loadUrl("http://www.yahoo.co.in");
        setTitle("Yahoo!");
    }
}
