[英]Json - JSONArray cannot be converted to JSONObject
I'm new to JSON. 我是JSON的新手。 I'm trying to read the String in JSON but it throw me an error.
我正在尝试读取JSON中的字符串,但它给我抛出了一个错误。
String strResponse = "{"IndustryList" : [{"industryId" : "1","industryName" : "Bird Nest","industryStatus" : "0","industryDescription" : "Bird nest industry","industryIconFilepath" : "","industryIconFilename" : ""},{"industryId" : "2","industryName" : "Medicine","industryStatus" : "0","industryDescription" : "Medicine Products","industryIconFilepath" : "","industryIconFilename" : ""}]}"
JSONObject json_data = new JSONObject(strResponse);
JSONArray nameArray = json_data.names();
JSONArray valArray = json_data.toJSONArray(nameArray);
Log.i(MainActivity.class.getName(),
"Number of entries " + valArray.length());
for (int i = 0; i < valArray.length(); i++) {
JSONObject jsonObject = valArray.getJSONObject(i);
Log.i(MainActivity.class.getName(), jsonObject.getString("text"));
}
Error: 错误:
at 0 of type org.json.JSONArray cannot be converted to JSONObject
The problem is that toJSONArray
returns array of values. 问题是
toJSONArray
返回值数组。 And it has only 1 element - industryList
value. 它只有1个元素
industryList
值。 Which is array itself. 这是数组本身。 So you need to iterate throw
valArray.getJSONArray(0)
not through valArray
因此,您需要迭代抛出
valArray.getJSONArray(0)
而不是通过valArray
