public class ilias extends Activity { 

WebView webView; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     webView = (WebView)findViewById(R.id.webview); 

     BufferedReader bufferedReader = null; 
     HttpClient httpClient = new DefaultHttpClient(); 
     HttpPost request = new HttpPost("http://www.ilias.de/docu/login.php?client_id=docu"); 
     List<NameValuePair> postParameters = new ArrayList<NameValuePair>(); 
     postParameters.add(new BasicNameValuePair("username", "stacked")); //this username 
     postParameters.add(new BasicNameValuePair("password", "overflow"));//works 


    try { 
    UrlEncodedFormEntity entity = new UrlEncodedFormEntity(postParameters); 
     request.setEntity(entity); 

     HttpResponse response= httpClient.execute(request); 

    bufferedReader = new BufferedReader(
      new InputStreamReader(response.getEntity().getContent())); 
    StringBuffer stringBuffer = new StringBuffer(""); 
    String line = ""; 
    String LineSeparator = System.getProperty("line.separator"); 
    while ((line = bufferedReader.readLine()) != null) { 
    stringBuffer.append(line + LineSeparator); 
    } 
    bufferedReader.close(); 

    Toast.makeText(ilias.this, 
    "Finished", 
    Toast.LENGTH_LONG).show(); 

    String webData = stringBuffer.toString(); 

    webView.setWebViewClient(new WebViewClient()); 
    webView.loadDataWithBaseURL("http://www.ilias.de/docu/",webData,"text/html","UTF-8","about:blank"); 
    String postData = "username=stacked&password=overflow";

你只需要創建一個自己的WebViewClient。然後，你可以保存URL它被調用前/圖所示：

private class MyWebViewClient extends WebViewClient { 
    @Override 
    public boolean shouldOverrideUrlLoading(WebView view, String url) { 

        // save url here 

     // false = open all urls with the embedded browser 
     return false; 
    } 
} 

現在的網頁視圖客戶端添加到網頁視圖：

webView.setWebViewClient(new MyWebViewClient());
