我试图按如下方式解析它，
for (int i = 0; i < response.length(); i++) {
try {
// Toast.makeText(getActivity(), response.toString(), Toast.LENGTH_SHORT).show();
JSONObject value = response.getJSONObject(i);
JSONObject statutory_mappings = value.getJSONObject("statutory_mappings");
Iterator<String> keys = statutory_mappings.keys();
while (keys.hasNext()) {
String key = (String) keys.next();
JSONObject statMap = statutory_mappings.getJSONObject(key);
//iterate geography id's in case if there comes any necessity
JSONArray geography_ids = statMap.getJSONArray("geography_ids");
JSONObject approval_status = statMap.getJSONObject("approval_status");
String approval_status_text = statMap.getString("approval_status_text");
JSONArray compliance_names = statMap.getJSONArray("compliance_names");
String statutory_nature_name = statMap.getString("statutory_nature_name");
String country_id = statMap.getString("country_id");
String domain_name = statMap.getString("domain_name");
String industry_names = statMap.getString("industry_names");
String is_active = statMap.getString("is_active");
String statutory_nature_id = statMap.getString("statutory_nature_id");
JSONArray statutory_ids = statMap.getJSONArray("statutory_ids");
String country_name = statMap.getString("country_name");
JSONArray industry_ids = statMap.getJSONArray("industry_ids");
JSONArray geography_mappings = statMap.getJSONArray("geography_mappings");
JSONArray compliances = statMap.getJSONArray("compliances");
String compliance_id = statMap.getString("compliance_id");
JSONArray inner_statutory_mappings = statMap.getJSONArray("statutory_mappings");
String domain_id = statMap.getString("domain_id");
String logs = geography_ids + ""+ approval_status + " "+approval_status_text + " "+ compliance_names + " "+ statutory_nature_name + " "+country_id + " "+domain_name + " "+ industry_names + " "+is_active + " "+statutory_ids + " "+statutory_nature_id + " "+ country_name + " "+industry_ids + " "+ geography_mappings + " "+compliances + " "+compliance_id + " "+inner_statutory_mappings + " "+domain_id;
Toast.makeText(getActivity(),geography_ids.toString(),Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
e.printStackTrace();
}
}
问题在于我无法解析它。它打印geography_ids但不打印批准状态和其他值。为什么会这样？我错过了任何逻辑吗？
答案 0 :(得分：1)
问题1
你的json有这种格式：
[
"GetStatutoryMappingsSuccess",
{...}
]
因此，当您尝试对此数组进行迭代时，您将获得1个Exeption：
org.json.JSONException: JSONArray[0] is not a JSONObject.因为1-st元素不是JsonObject而是String。这就是为什么你最好只使用JSONObject value = new JSONArray(json).getJSONObject(1);代替for loop
问题2
你有第二个对象
{
"statutory_mappings": {
"5": {
"approval_status": 0,
...
}
}
}
你的解析代码应该有效，但是“approval_status”是整数，所以不是
JSONObject approval_status = statMap.getJSONObject("approval_status");
应该是：
int approval_status = statMap.getInt("approval_status");
// Same problem for:
int country_id = statMap.getInt("country_id");
boolean is_active = statMap.getBoolean("is_active");
int statutory_nature_id = statMap.getInt("statutory_nature_id");
int domain_id = statMap.getInt("domain_id");
问题3
compliance_id也存在问题，json看起来像这样
"compliances": [
{
// ... some fields here
"compliance_id": 13
},
{
// ... some fields here
"compliance_id": 14
},
...
]
所以没有必要在你的日志字符串中打印compliances，如果你真的想要获得数组中aach元素的compliance_id，你必须像这样对它们进行ittorate
JSONArray compliancesArr = statMap.getJSONArray("compliances");
for(int i = 0; i < compliancesArr.length();i++){
JSONObject compliancesObj = compliancesArr.getJSONObject(i);
int compliance_id = compliancesObj.getInt("compliance_id");
}
PS。 Gson或Jackson将使您的解析代码更容易。
