私は以下のコードを使用してURLからhtmlソースを取得することを意味します。しかし、すべてのソースが含まれているわけではありません。Buffersizeは問題ですか、それとも文字列サイズの問題ですか？

HttpURLConnection connection; 
            OutputStreamWriter request = null; 

                 URL url = null;    
                 String response = null;          
                 String parameters = "aranan="+et.getText();    

                 try 
                 { 
                     url = new URL("http://www.fragmanfan.com/arama.asp"); 
                     connection = (HttpURLConnection) url.openConnection(); 
                     connection.setDoOutput(true); 
                     connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 

                     request = new OutputStreamWriter(connection.getOutputStream()); 
                     request.write(parameters); 
                     request.flush();             
                     String line = "";                
                     InputStreamReader isr = new InputStreamReader(connection.getInputStream()); 
                     BufferedReader reader = new BufferedReader(isr); 
                     StringBuilder sb = new StringBuilder(); 
                     while ((line = reader.readLine()) != null) 
                     { 
                         sb.append(line + "\n"); 
                     } 
                     // Response from server after login process will be stored in response variable.                 
                     response = sb.toString(); 
                     // You can perform UI operations here 
                     browser.loadDataWithBaseURL(null, response,"text/html", "UTF-8", null); 

                     isr.close(); 
                     reader.close(); 

                 } 
                 catch(IOException e) 
                 { 
                     // Error 
                 } 




        } 
    });

私は次のようなことを試みます が、うまくいきBufferedReader reader = new BufferedReader(isr,8192); ません。

WebRequestクラスを作成します。あなたの要求をして、応答を得るより。私はそのウェブサイトを試しました、それは動作します。

WebRequest response = new WebRequest("http://www.fragmanfan.com/arama.asp?aranan=kurtlar", PostType.GET);
String htmltext = response.Get();
browser.loadDataWithBaseURL(null, htmltext, "text/html", "UTF-8", null);

    }

    return response;
  }

  private StringBuilder inputStreamToString(InputStream is) throws IOException {

問題がありました。

私は使用 Log.i("tag", html) しましたが、ロガーには最大長のメッセージがあります。そして私のhtmlテキストは切り取られました。2つの解決策があります：

  1. HTMLを細かく分割します
  2. この投稿のように、メッセージの最大長のサイズを大きくします： リンク
