使用 RSS 项目的 getValue 在 <image> 标签中获取字符串 - Android
Get String In <image> Tags With getValue of RSS Item - Android
如何使用 getValue 获取 <image>
标签中的字符串?<image>https://i2.cnnturk.com/i/cnnturk/75/720x490/5e6f7a9a70380e0cc8f49313</image>
我需要 https://i2.cnnturk.com/i/cnnturk/75/720x490/5e6f7a9a70380e0cc8f49313
作为值。
我可以显示图像,如果它是 <media:content url=""/>
<media:thumbnail url=""/>
<enclosure url=""/>
并且还需要显示 <image>
。
还有什么方法可以将 RSS 发布日期 GMT 格式化为 GMT+3?我需要显示为不同的时区。

这里是android代码:
需要帮助
else if (qName.equalsIgnoreCase("image")) { //NEW ADDITION
currentState = State.media;
String attrValue = attributes.getValue("WHAT");
item.setThumburl(attrValue);
_完整代码
@Override
public void startElement(final String uri, final String localName,
final String qName, final Attributes attributes)
throws SAXException {
currentState = State.unknown;
tagContent = new StringBuilder();
if (localName.equalsIgnoreCase("item") || localName.equalsIgnoreCase("entry")) {
itemFound = true;
item = new RSSItem();
currentState = State.unknown;
} else if (qName.equalsIgnoreCase("title")) {
currentState = State.title;
} else if (qName.equalsIgnoreCase("description") || qName.equalsIgnoreCase("content:encoded") || qName.equalsIgnoreCase("content")) {
currentState = State.description;
} else if (qName.equalsIgnoreCase("link") || qName.equalsIgnoreCase("origLink")) {
currentState = State.link;
} else if (qName.equalsIgnoreCase("pubdate") || qName.equalsIgnoreCase("published")) {
currentState = State.pubdate;
} else if (qName.equalsIgnoreCase("image")) { //NEW ADDITION
currentState = State.media;
String attrValue = attributes.getValue("WHAT");
item.setThumburl(attrValue);
} else if (qName.equalsIgnoreCase("media:thumbnail")) {
currentState = State.media;
String attrValue = attributes.getValue("url");
item.setThumburl(attrValue);
} else if (qName.equalsIgnoreCase("media:content")){
currentState = State.media;
String attrValue = attributes.getValue("url");
if (attributes.getValue("type") == null || attributes == null){
return;
} else if (attributes.getValue("type").startsWith("image")){
item.setThumburl(attrValue);
} else if (attributes.getValue("type").startsWith("video")){
item.setVideourl(attrValue);
} else if (attributes.getValue("type").startsWith("audio")){
item.setAudiourl(attrValue);
}
} else if (qName.equalsIgnoreCase("enclosure")){
currentState = State.media;
String attrValue = attributes.getValue("url");
if (attributes == null || attributes.getValue("type") == null) {
return;
} else if (attributes.getValue("type").startsWith("image")){
item.setThumburl(attrValue);
} else if (attributes.getValue("type").startsWith("video")){
item.setVideourl(attrValue);
} else if (attributes.getValue("type").startsWith("audio")){
item.setAudiourl(attrValue);
}
}
}
可以试试正则表达式\<(\Qimage\E)\>(.*?)\<\/\>
匹配对应characters.It可以匹配所有图片标签的内容
public static void main(String[] args){
String s="<image>https://x.com/image.jpg</image>"
+ "<image>https://x.com/image1.jpg</image>"
+ "<image>https://x.com/image2.jpg</image>";
Pattern p = Pattern.compile("\<(\Qimage\E)\>(.*?)\<\/\1\>");
Matcher m = p.matcher(s);
while(m.find()){
System.out.println(m.group(2));
}
}
更新:我刚刚更新了代码。不好意思之前写错了
如果您不想使用正则表达式
int record = 0;
while(record!=-1){
int a = qName.indexOf("<image>",record);
if(a==-1){
break;
}
int b = qName.indexOf("</image>",a);
String url=qName.substring(a+7,b+8);
System.out.println(url);
}
String sete = "<image>https://x.com/a.jpg</image>";
String sete2 = sete.replace("<image>", "");
