您好,我想将 HTML 表解析为 Android ListView,但我不知道从哪里开始。该表有很多信息。有人可以帮我从这个开始吗?
提前致谢!

您首先需要将 HTML 表解析为数据结构,然后使用 ListView 显示该信息。尝试使用 JSoup 库进行 HTML 解析:http: //jsoup.org/cookbook/introduction/parsing-a-document
到目前为止,我认为 JSoup 是提取或操作 HTML 的最佳方法之一......
请参阅此链接:
但不知何故......这在我的情况下不起作用,所以我将整个 HTML 代码转换为字符串,然后解析它......
我不知道你是否已经在这里得到了答案,但我对你建议的链接做了同样的事情,我会在这里发布我的代码,但它仍然很乱,不要申请最新的时间表(第 9 小时)
我使用 HTML Cleaner 库来解析 html:
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 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());

case 3:

return false;

} else if (t3.getLength() == 1) {

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;
}
有一些常量,但我认为您可以自己猜到它们;)否则您知道如何向我询问它们:)
RoosterItem 类将保存一小时的所有变量,而 RoosterItems 将保存多个 RoosterItem
祝你好运!
