如何解析这种格式的json数组？
解析时出现此错误：“无法转换为 json 对象”。
将当前 Json 字符串解析为：
JSONObject json=new JSONObject("Your Json String");
JSONArray jsonarray = json.getJSONArray("TABLE");
for(int i=0;i<jsonarray.length();i++){
JSONObject jsonnew=jsonarray.getJSONObject(i);
JSONArray jsonarrayROW = jsonnew.getJSONArray("ROW");
for(int j=0;j<jsonarrayROW.length();j++){
JSONObject jsonnewtwo=jsonarrayROW.getJSONObject(j);
JSONArray jsonarrayCOL = jsonnewtwo.getJSONArray("COL");
for(int k=0;k<jsonarrayCOL.length();k++){
JSONObject jsonnewthree=jsonarrayCOL.getJSONObject(k);
//get DATA here
String str_data=jsonnewthree.getString("DATA");
}
}
}
看这里
String jsonStr = '{"menu": {' +
'"id": "file",' +
'"value": "File",' +
'"popup": {' +
'"menuitem": [' +
'{"value": "New", "onclick": "CreateNewDoc()"},' +
'{"value": "Open", "onclick": "OpenDoc()"},' +
'{"value": "Close", "onclick": "CloseDoc()"}' +
']' +
'}' +
'}}';
在这里看到很好的例子JSON PARSING
它的工作解析 json 数据数组在数组中
