如何在Android中从PHP管理和读取JSON数组
问题描述：
我有很多以这种方式格式化的json数组:
I've lots of json array which are formatted in this way:
[
{
"cod_ent":"953",
"name_ent":"example1",
"amb":{
"15":{
"cod_amb":"002",
"name_amb":"Or11"
},
"1723":{
"cod_amb":"00009",
"name_amb":"P3o1"
}
}
}
]
，我想在android中正确阅读.我尝试使用此代码，并且设法检索了前两个条目("cod_ent"和"name_ent")，但是我仍然无法管理"amb"子数组.
and i'd like to read it correctly in android. I try with this code and i manage to retrieve the first two entries ("cod_ent" and "name_ent") but i'm still not able to manage "amb" sub-array.
JSONObject json = null;
try {
InputStream pre_json = response.getEntity().getContent();
json = new JSONObject("{data:"+convertStreamToString(pre_json)+"}");
} catch (IOException e) {
e.printStackTrace();
}
JSONArray jsonArray = json.getJSONArray("data");
for (int i = 0; i < jsonArray.length(); i++){
JSONObject getfromarray = jsonArray.getJSONObject(i);
cod_ent = getfromarray.getString("cod_ent");
name_ent = getfromarray.getString("name_ent");
//how to get amb???
}
答
您可以像这样迭代JSONObject:
You can Iterate JSONObject Like this:
JSONObject jsonObject =getfromarray.getJSONObject("amb")
Iterator<String> iter = jsonObject.keys();
while (iter.hasNext()) {
String key = iter.next();
Log.w("Key", key);
try {
JSONObject js = jsonObject.getJSONObject(key);
Log.w("cod_amb", js.getString("cod_amb"));
Log.w("name_amb", js.getString("name_amb"));
} catch (Exception e) {
// TODO: handle exception
}
}
