我一直按照这里的说明操作: https://www.codenameone.com/javadoc/com/codename1/io/JSONParser.html从json文件中检索值。 我已设法读取我的json内容的顶级值 - 但是我看不到如何读取嵌套标记的值,例如使用此文件......
{
"glossary":{
"title":"example glossary",
"GlossDiv":{
"title":"S",
"GlossList":{
"GlossEntry":{
"ID":"SGML",
"SortAs":"SGML",
"GlossTerm":"Standard Generalized Markup Language",
"Acronym":"SGML",
"Abbrev":"ISO 8879:1986",
"GlossDef":{
"para":"A meta-markup language, used to create markup languages such as DocBook.",
"GlossSeeAlso":[
"GML",
"XML"
]
},
"GlossSee":"markup"
}
}
}
}
}
有人可以告诉我如何获得上面“para”的价值吗?
谢谢

根据count()
解析json数据后,您可以使用Result
深入了解json内容:
import com.codename1.processing.Result;
...
Map<String, Object> data = json.parseJSON(r);
Result result = Result.fromContent(data);
String id = result.getAsString("glossary/GlossDiv/GlossList/GlossEntry/ID");
String para = result.getAsString("glossary/GlossDiv/GlossList/GlossEntry/GlossDef/para");
