停止加載webview並返回到上一頁

Question

我想停止加載網址的webview，當它以google.com開頭並從示例返回到默認頁面時[1]。頁]。

在我的webview客戶端下面它不會返回到第一頁thougth應該重寫方法的條件是好的。

public class myWebClient extends WebViewClient 
     { 
      @Override 
      public void onPageStarted(WebView view, String url, Bitmap favicon) { 
       // TODO Auto-generated method stub 
       super.onPageStarted(view, url, favicon); 
       // view.setVisibility(View.GONE); 
       rlChargement.setVisibility(View.VISIBLE); 
       progresswheel.spin(); 
      } 
      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       // TODO Auto-generated method stub 
       // view.setVisibility(View.GONE); 
       System.out.println("BROWSER URL : "+url); 
       //Recherche sans filtre 
       if (url.equalsIgnoreCase("http://www.google.com")){ 
        System.out.println("INVALID"); 
        web.clearCache(true); 
        ActToast.message="error message"; 
        startActivity(new Intent(me, ActToast.class)); 
        rlChargement.setVisibility(View.GONE); 
        progresswheel.stopSpinning(); 
        view.stopLoading(); 
        web.clearHistory(); 
       } 

       view.loadUrl(url); 
       return true; 
      } 
      @Override 
      public void onPageFinished(WebView view, String url) { 
       // TODO Auto-generated method stub 
       super.onPageFinished(view, url); 
       // animate(view); 
       // view.setVisibility(View.VISIBLE); 
       rlChargement.setVisibility(View.GONE); 
       progresswheel.stopSpinning(); 
      } 
      public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
       web.loadUrl("file:///android_asset/onreceivingerror.html"); 
      } 
     }

您可能要重寫WebView.goBack（）：

@Override 
    public void goBack() { 
    WebBackForwardList temp = copyBackForwardList(); 
    for (int i=0; i<temp.getSize(); i++) { 
     WebHistoryItem item = temp.getItemAtIndex(i); 
     // do whatever you want here... 
    } 

    // do whatever you want here... 
    super.goBack(); 
    }
