Android Tip: Enable a progress bar for a WebView

This is how you enable a progress bar when loading web pages using a WebView in Android:

final Activity activity = this;

     

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        getWindow().requestFeature(Window.FEATURE_PROGRESS);

        setContentView(R.layout.main);

     

       

        String url = "http://m.bing.com";

        WebView web = (WebView) findViewById(R.id.mainView);

             web.getSettings().setJavaScriptEnabled(true); 

             web.getSettings().setBuiltInZoomControls(true);

             web.getSettings().setUseWideViewPort(true);

              web.setWebChromeClient(new WebChromeClient() {

                  public void onProgressChanged(WebView view, int progress) {

                        activity.setProgress(progress * 100);

                  }

              });

             web.loadUrl(url);

       

    }

Note: requestFeature() must be call before any other content is added (call it right after super.onCreate).
