英文:
How do I parse this JSON object to get a list of recipe objects that I can then use?
问题
这是我目前正在使用的解析 JSON 对象的方法：
public void onResponse(Call call, Response response) throws IOException {
if (response.isSuccessful()) {
final String myResponse = response.body().string();
getActivity().runOnUiThread(new Runnable() {
private Object Date;
@Override
public void run() {
String jsonData = myResponse;
query_result.setText(myResponse);
Log.d("response5", myResponse);
try {
JSONObject Jobject = new JSONObject(jsonData);
Log.d("jobject", Jobject.toString());
JSONArray Jarray = Jobject.getJSONArray("hits");
for (int i = 0; i < Jarray.length(); i++) {
JSONObject object = Jarray.getJSONObject(i);
JSONObject recipeObject = object.getJSONObject("recipe");
String name = recipeObject.getString("label");
String photo = recipeObject.getString("image");
Log.d("rec_query", " " + name + " - " + photo);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
});
}
}
注意：{} {} 只是不同的食谱……它们不能包含整个响应内容。
目前，当我尝试在日志中打印我的变量时，我得到了一个消息，说这个变量是空的（用来存储不同的食谱/“hits”的变量）。

So I am incredibly new to Java and am needing help parsing a JSON response. I already have the method in which I am using to do so, but need help figuring out what exactly I am doing wrong.
I am using an API to retrieve recipes from a site. I am trying to get a list of recipes ("hits" in this case I assume?) that I can then show to the user.
Obviously I need the recipe name ("label" in this case) and other information. Can anyone help me?
Here is the response api response I am getting:

This is currently the method I am using to parse the JSON object:
public void onResponse(Call call, Response response) throws IOException {
if (response.isSuccessful()) {
final String myResponse = response.body().string();
getActivity().runOnUiThread(new Runnable() {
private Object Date;
@Override
public void run() {
String jsonData = myResponse;
query_result.setText(myResponse);
Log.d("response5", myResponse);
//JSONObject jsonData1 = new JSONObject(myResponse);
JSONObject Jobject = null;
try {
Jobject = new JSONObject(jsonData);
Log.d("jobject", Jobject.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JSONArray Jarray = null;
try {
Jarray = Jobject.getJSONArray("hits");
} catch (JSONException e) {
e.printStackTrace();
}
for (int i = 0; i < Jarray.length(); i++) {
JSONObject object;
try {
object = Jarray.getJSONObject(i);
try {
JSONArray Recipe = object.getJSONArray("recipe");
}catch (JSONException e){
e.printStackTrace();
}
for (int j = 0; j < Jarray.length(); j++){
JSONObject object2 = null;
try {
object2 = Jarray.getJSONObject(j);
String Name = object2.getString("label");
String Photo = object2.getString("image");
Log.d("rec_query", " " + Photo);
}catch (JSONException e){
e.printStackTrace();
Log.d("response6:", e.toString());
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
});
}
}
});
return null;
}
}
NOTE THE {} {} are just different recipes...it wouldnt fit the whole response
At the moment, when I try to print my variables in the Log, I am getting a message that says the variable is empty (the variable that i used to store the different recipes/"hits".

Sure, here's the translated code portion:
String s = "{\n" +
" \"a1\":\"1\",\n" +
" \"b2\":[\n" +
" {\n" +
" \"b21\":\"vb21\"\n" +
" },\n" +
" {\n" +
" \"b22\":\"vb22\"\n" +
" }\n" +
" ]\n" +
"}";
JSONObject object = JSON.parseObject(s);
String vb21 = object.getJSONArray("b2").getJSONObject(0).getString("b21");
Please note that this code snippet uses the FastJSON library for JSON parsing, and you'll need to import com.alibaba.fastjson to use it.
英文:
String s = "{\n" +
" \"a1\":\"1\",\n" +
" \"b2\":[\n" +
" {\n" +
" \"b21\":\"vb21\"\n" +
" },\n" +
" {\n" +
" \"b22\":\"vb22\"\n" +
" }\n" +
" ]\n" +
"}";
JSONObject object = JSON.parseObject(s);
String vb21 = object.getJSONArray("b2").getJSONObject(0).getString("b21");
like this,and neep to import com.alibaba.fastjson
But i dont`t know if you can use fastjson
