每个新闻条目都有三个内容：标题,内容和日期.
从数据库中检索条目,我想在我的应用程序中使用JSONObject和JSONArray读取它们.但是,我不知道如何使用这些类.
这是我的JSON字符串：
[
{
"news":{
"title":"5th title","content":"5th content","date":"1363197493"
}
},{
"news":{
"title":"4th title","content":"4th content","date":"1363197454"
}
},{
"news":{
"title":"3rd title","content":"3rd content","date":"1363197443"
}
},{
"news":{
"title":"2nd title","content":"2nd content","date":"1363197409"
}
},{
"news":{
"title":"1st title","content":"1st content","date":"1363197399"
}
}
]
解决方法
您的JSON字符串是JSONObject的JSONArray,然后包含一个名为“news”的内部JSONObject.
试试这个来解析它：
JSONArray array = new JSONArray(jsonString);
for(int i = 0; i < array.length(); i++) {
JSONObject obj = array.getJSONObject(i);
JSONObject innerObject = obj.getJSONObject("news");
String title = innerObject.getString("title");
String content = innerObject.getString("content");
String date = innerObject.getString("date");
/* Use your title,content,and date variables here */
}
