如何在android中获取json值

I read many example and try it. But it didn't work to get the value.
The result returned a whole JSON to me.
I don't know where is wrong...
This is my first time to ask question. Thanks for help.
Here is my JSON and JAVA Code.
JSON:`
{
"food":{
"name":"XXX Food",
"details":{
"code":"01",
"location":{
"area":"Area D",
"place":"Food"
},
"price":"132.21",
"discount":"15%"
}
}
}
Now, I want to get the price.
JAVA Code:
JSONObject json = new JSONObject(recvStr);
JSONArray Results = json.getJSONArray("food");
JSONArray msg = Results.getJSONArray(0);
result = msg.getJSONObject(0).getString("price");
解决方案
Results is not a JSONArray but a JSONObject:
JSONObject results = json.getJSONObject("food");
String name = results.getString("name");
JSONObject details = results.getJSONObject("details");
String price = details.getString("price");
You can read more about JSON at json.org.
