Android：如何解析HTML表格到ListView？

Question

你好，我想解析一個HTML表格到Android ListView中，但我不知道從哪裏開始。該表有很多信息。有人可以幫我開始嗎？

在此先感謝！

我不知道我如果你已經在這裏得到了你的答案，但是我對你建議的鏈接也做了同樣的事情，我會在這裏發佈我的代碼，但它仍然很雜亂，不適用最新的時間表（第9小時）

使用HTML爲解析HTML清潔庫：

try { 
     HtmlCleaner hc = new HtmlCleaner(); 
     CleanerProperties cp = hc.getProperties(); 
     cp.setAllowHtmlInsideAttributes(true); 
     cp.setAllowMultiWordAttributes(true); 
     cp.setRecognizeUnicodeChars(true); 
     cp.setOmitComments(true); 

     String loc = sp.getString(Constants.pref_locatie  , ""); 
     String per = sp.getString(Constants.pref_persoon  , ""); 
     String oob = sp.getString(Constants.pref_onderofboven , ""); 

     int counteruurmax; 
     int[] pauze; 
     if (oob.contains("onder")){ 
      pauze = Constants.pauzeo; 
     } else if (oob.contains("boven")) { 
      pauze = Constants.pauzeb; 
     } else { 
      return false; 
     } 

     String url = ""; 
     if (loc.contains("lochem")) { 
      url += Constants.RoosterLochem; 
      url += t.getDatum(); 
      url += "/"; 
      url += per; 
      counteruurmax = 11; 
     } else if (loc.contains("herenlaan")) { 
      url += Constants.RoosterHerenlaan; 
      url += per; 
      counteruurmax = 13; 
     } else if (loc.contains("beukenlaan")) { 
      url += Constants.RoosterBeukenlaan; 
      url += per; 
      counteruurmax = 11; 
     } else { 
      return false; 
     } 

     String htmlcode = t.getHtml(url); 
     TagNode html = hc.clean(htmlcode); 
     Document doc = new DomSerializer(cp, true).createDOM(html); 
     XPath xp = XPathFactory.newInstance().newXPath(); 
     NodeList nl = (NodeList) xp.evaluate(Constants.XPathRooster, doc, XPathConstants.NODESET); 

     int counteruur = 1; 
     int counterdag = 1; 
     int decreaser = 0; 
     Boolean isPauze = false; 
     RoosterItems RItems = new RoosterItems(); 
     RoosterItem RItem = null; 
     for (int i = 0; i < nl.getLength(); i++){ 

      if ((counteruur == pauze[0]) || (counteruur == pauze[1]) || (counteruur == pauze[2])) { 
       isPauze = true; 
       decreaser++; 
      } 

      if (!isPauze) { 
       RItem = new RoosterItem(); 
       switch (counterdag){ 
       case 1: 
        RItem.setDag("ma"); 
        break; 
       case 2: 
        RItem.setDag("di"); 
        break; 
       case 3: 
        RItem.setDag("wo"); 
        break; 
       case 4: 
        RItem.setDag("do"); 
        break; 
       case 5: 
        RItem.setDag("vr"); 
        break; 
       } 

       Node n = nl.item(i); 
       String content = n.getTextContent(); 
       if (content.length() > 1) { 
        RItem.setUur(""+(counteruur-decreaser)); 
        NodeList t1 = n.getChildNodes(); 
        NodeList t2 = t1.item(0).getChildNodes(); 
        NodeList t3 = t2.item(0).getChildNodes(); 
        for (int j = 0; j < t3.getLength(); j++) { 
         Node temp = t3.item(j); 
         if (t3.getLength() == 3) { 
          switch (j) { 
          case 0: 
           RItem.setLes(""+temp.getTextContent()); 
           break; 
          case 1: 
           RItem.setLokaal(""+temp.getTextContent()); 
           break; 
          case 2: 
           RItem.setDocent(""+temp.getTextContent()); 
           break; 
          default: 
           return false; 
          } 
         } else if (t3.getLength() == 4) { 
          switch (j) { 
          case 0: 
           break; 
          case 1: 
           RItem.setLes("tts. " + temp.getTextContent()); 
           break; 
          case 2: 
           RItem.setLokaal(""+temp.getTextContent()); 
           break; 
          case 3: 
           RItem.setDocent(""+temp.getTextContent()); 
           break; 
          default: 
           return false; 
          } 
         } else if (t3.getLength() == 1) { 
          RItem.setLes(""+temp.getTextContent()); 
         } else { 
          return false; 
         } 
        } 
       } else { 
        RItem.setUur("" + (counteruur-decreaser)); 
        RItem.setLokaal("Vrij"); 
       } 
       RItems.add(RItem); 
      } 
      if (counteruur == counteruurmax) { counteruur = 0; counterdag++; decreaser = 0;} 
      counteruur++; 
      isPauze = false; 
     } 

     if (RItems.size() > 0) { 
      mSQL = new RoosterSQLAdapter(mContext); 
      mSQL.openToWrite(); 
      mSQL.deleteAll(); 
      for (int j = 0; j < RItems.size(); j++) { 
       RoosterItem insert = RItems.get(j); 
       mSQL.insert(insert.getDag(), insert.getUur(), insert.getLes(), insert.getLokaal(), insert.getDocent()); 
      } 
      if (mSQL != null) mSQL.close(); 
     } 
     return true; 
    } catch (ParserConfigurationException e) { 
     e.printStackTrace(); 
     return false; 
    } catch (XPathExpressionException e) { 
     e.printStackTrace(); 
     return false; 
    } 

有幾個常數，但我認爲你可以自己猜測他們;），否則你知道如何讓我爲他們:)

的RoosterItem類將舉行一小時的所有變量，並且RoosterItems將持有多於​​一個的RoosterItem

祝你好運！

您首先需要將HTML表格解析爲數據結構，然後使用ListView來顯示該信息。嘗試使用JSoup庫做HTML解析：http://jsoup.org/cookbook/introduction/parsing-a-document

Answer 3

到目前爲止，我認爲JSoup是提取或操縱HTML的最好方式一個.....

請參閱此鏈接：

http://jsoup.org/

但不知何故....這在我的情況我以前不工作，所以我轉換的整個HTML代碼轉換成字符串，然後解析吧.....
