Question on adding progress bar codes on blogwebview (blogreaderapp) HELP!

Dear all:

I am trying to add the progress bar codes on the BlogWebViewActivity.java However, no matter how slow the webview is load. The progress bar never read pop out.

here is my code.

        @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_blog_web_view);
        mProgressBar = (ProgressBar) findViewById(R.id.progressBar1);
        mProgressBar.setVisibility(View.VISIBLE);
        Intent intent = getIntent();
        Uri blogUri = intent.getData();
        mUrl = blogUri.toString();
        WebView webView = (WebView) findViewById(R.id.webView1);
        webView.loadUrl(mUrl);
        mProgressBar.setVisibility(View.INVISIBLE);
    }

I am wondering if this is cause by the fact that the webpage is still loading after the mProgressBar.setVisibility(View.INVISIBLE) have already execute.

If yes, how should i modify it to make it to work? Thank you very much!

Wayne

Hi guys. I manage to pull this out by using the technique in the following link: http://www.technotalkative.com/android-load-webview-with-progressbar/

And here is my modification for it

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_blog_web_view);
        mProgressBar = (ProgressBar) findViewById(R.id.progressBar1);
        mProgressBar.setVisibility(View.VISIBLE);
        Intent intent = getIntent();
        Uri blogUri = intent.getData();
        mUrl = blogUri.toString();
        WebView webView = (WebView) findViewById(R.id.webView1);
        webView.setWebViewClient(new mWebClient());
        webView.loadUrl(mUrl);
    }

    public class mWebClient extends WebViewClient
    {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;        
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);    
            mProgressBar.setVisibility(View.GONE);
        }
    }

If anyone could confirm my code, that would be awesome!

Thank you very much!
