问题描述

我想显示一个警告框，而不是找不到网页在我的Web视图错误页，但无法正常工作，甚至加入onReceivedError（）方法，每个文件后，请建议我，如果我想的东西，这里是我的code ...

I'm trying to show an alert box instead of 'Web page not available' error page on my web view but not working even after adding onReceivedError() method as per documentation, please suggest me if I'm missing something, Here is my code...

public class CloudPageHolder extends Activity {
WebView mWebView;
ProgressDialog _dialog ;
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

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


    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setDomStorageEnabled(true);
    mWebView.loadUrl("file:///android_asset/www/MyPage.html");
    mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(false);
    mWebView.getSettings().setPluginsEnabled(false);
    mWebView.getSettings().setSupportMultipleWindows(false);
    mWebView.getSettings().setSavePassword(false);
    mWebView.getSettings().getAllowFileAccess();
    mWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
    mWebView.getSettings().setUseWideViewPort(true);
    mWebView.getSettings().setLoadWithOverviewMode(true);

    mWebView.setWebViewClient(new WebViewClient() {  
        public void onReceivedError(WebView view, int errorCode, String description,     String failingUrl) {  
          new AlertDialog.Builder(CloudPageHolder.this)  
                .setMessage("Something went wrong!")  
                .setPositiveButton(android.R.string.ok,  
                        new AlertDialog.OnClickListener()  
                        {  
                           public void onClick(DialogInterface dialog, int which)  
                            { 

                               dialog.dismiss();
                            }  
                        })  
                .setCancelable(false)  
                .create()  
                .show();  
                }  
        });  


    mWebView.setWebChromeClient(new WebChromeClient() {  
        @Override  
        public boolean onJsAlert(WebView view, String url, final String message, final android.webkit.JsResult result)  
        {  
            new AlertDialog.Builder(CloudPageHolder.this)  
                .setMessage(message)  
                .setPositiveButton(android.R.string.ok,  
                        new AlertDialog.OnClickListener()  
                        {  
                           public void onClick(DialogInterface dialog, int which)  
                            { 
                               result.confirm();
                            }  
                        })  
                .setCancelable(false)  
                .create()  
                .show();  

            return true;  
        } 
  });
 }

先谢谢了...

Thanks in Advance...

推荐答案

我不知道什么你的错误只是onReceivedError的文档有所missleading。
在这一点上，你无法截取使用这种方法的HTTP错误响应。
检查这些职位的。

I am not sure of what your error is but the documentation of onReceivedError is somewhat missleading. At this point you CANNOT intercept HTTP error responses using this method. check these posts.

我开发使用<一个中记载的方法类似的解决方法href=\"http://stackoverflow.com/questions/2592843/android-how-get-the-status-$c$c-of-an-httpclient-request\">this其他职位。

将与不久的细节更新。
祝你好运！

Will update with the details soon. Good luck!
