のWebViewいいえ「アクセス制御 - 許可 - 起源」ヘッダが存在[アンドロイド]で

Question

ベローは私のWebViewの設定は次のとおりです。

webView = (WebView) findViewById(R.id.webview); 

//  webView.clearHistory(); 
//  webView.getSettings().setLoadWithOverviewMode(true); 
//  webView.getSettings().setUseWideViewPort(true); 
//  webView.getSettings().setBuiltInZoomControls(true); 
//  webView.getSettings().setDomStorageEnabled(true); 
//  if (android.os.Build.VERSION.SDK_INT >= 16) 
//  { 
//   webView.enablecrossdomain41(); 
// 
//   webView.getSettings().setAllowUniversalAccessFromFileURLs(true); 
//   webView.getSettings().setAllowFileAccessFromFileURLs(true); 
// 
//  } 
//  else 
//  { 
//   webView.enablecrossdomain(); 
//  } 


    if (Build.VERSION.SDK_INT >= 16) { 
     webView.getSettings().setAllowUniversalAccessFromFileURLs(true); 
     webView.getSettings().setAllowFileAccessFromFileURLs(true); 
    }else{ 
     Class<?> clazz = webView.getSettings().getClass(); 
     Method method = null; 
     try { 
      method = clazz.getMethod("setAllowUniversalAccessFromFileURLs", boolean.class); 
      if (method != null) { 
       method.invoke(webView.getSettings(), true); 
      } 
      method = clazz.getMethod("setAllowFileAccessFromFileURLs", boolean.class); 
      if (method != null) { 
       method.invoke(webView.getSettings(), true); 
      } 
     } catch (NoSuchMethodException | InvocationTargetException | IllegalAccessException e) { 
      e.printStackTrace(); 
     } 

    } 
    webView.setWebViewClient(new MyWebViewClient()); 
    webView.getSettings().setLoadWithOverviewMode(true); 
    webView.getSettings().setJavaScriptEnabled(true); 

//  if (Build.VERSION.SDK_INT >= 11) { 
//   webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); 
// 

} 

    webView.loadUrl("http://jobs.bdjobs.com/jobdetails.asp?id=675496&fcatId=-1&ln=1"); 

ベローは私MyWebViewClientコードです：

private class MyWebViewClient extends WebViewClient { 
     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) { 
      view.loadUrl(request.getUrl().toString()); 
      return true; 
     } 

     @Override 
     public void onPageFinished(WebView view, String url) { 
      progress.setVisibility(View.GONE); 
      tv.setVisibility(View.GONE); 
      WebActActivity.this.progress.setProgress(100); 
      webView.setVisibility(View.VISIBLE); 
      super.onPageFinished(view, url); 
     } 

     @Override 
     public void onPageStarted(WebView view, String url, Bitmap favicon) { 
      progress.setVisibility(View.VISIBLE); 
      tv.setVisibility(View.VISIBLE); 
      webView.setVisibility(View.GONE); 
      WebActActivity.this.progress.setProgress(0); 
      super.onPageStarted(view, url, favicon); 
     } 

     @Override 
     public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) { 
      MyLog.e("error1", error.toString()); 
      handler.proceed(); 
     } 

     @Override 
     public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) { 
      MyLog.e("error2", error.toString()); 
     } 

     @Override 
     public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
      MyLog.e("error3", description); 
      MyLog.e("error3", failingUrl); 
     } 

     @Override 
     public void onTooManyRedirects(WebView view, Message cancelMsg, Message continueMsg) { 
      MyLog.e("error4", cancelMsg.toString()); 
      MyLog.e("error4", continueMsg.toString()); 
     } 
    }

：android webview - Access-Control-Allow-Origin

をしかし、それはどちらか動作していない

コンソールがいることを述べています。私はさらに何をすることができますか？コードの下

Answer 1

使用、

mWebview = (WebView) findViewById(R.id.mWebview); 
    mWebview.setWebViewClient(new myWebClient()); 
     mWebview.getSettings().setJavaScriptEnabled(true); 
     mWebview.setBackgroundColor(Color.parseColor("#daedf5")); 
     mWebview.loadUrl("http://jobs.bdjobs.com/jobdetails.asp?id=675496&fcatId=-1&ln=1"); 

WebViewのローダー：

/** 
* Load Webview with using Progressbar 
*/ 
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); 
    } 

    @Override 
    public boolean shouldOverrideUrlLoading(WebView view, String url) { 
     // TODO Auto-generated method stub 

     view.loadUrl(url); 
     return true; 

    } 

    @Override 
    public void onPageFinished(WebView view, String url) { 
     // TODO Auto-generated method stub 
     super.onPageFinished(view, url); 

     progressBar.setVisibility(View.GONE); 
    } 
}
