我需要显示JSON响应中的成分和度量的列表。我知道如何从整个响应中获得“类别”和“区域”。虽然,我不知道如何获取成分和度量值(成为我的recylerView的一部分,其中包括类别,区域等)。我需要在不同的cardViews中显示配方以及所有的成分和措施。
我已经发布了json响应和我的代码的片段。 谢谢
这是JSON响应

这是我从JSON响应中获取内容的方法,
我尝试了两次失败,但我不起作用
private void loadRecylerViewData () {
StringRequest stringRequest = new StringRequest(Request.Method.GET, URL_DATA,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray jsonArray = jsonObject.getJSONArray("meals");
String hello;
String ing = "strIngredient";
ArrayList<String> listIng = new ArrayList<>();
Log.e(" " + jsonArray.length(), "error");
for (int i = 0; i < (jsonArray.length()); i++) {
JSONObject o = jsonArray.getJSONObject(i);
for (int n = 1; n <= 20; n++)
{
hello = ing.concat(Integer.toString(n));
listIng.add( o.getString(hello));
}
element e = new element(o.getString("strCategory"), o.getString("strMealThumb "),
listIng);
elementList.add(e);
}
adapter = new recylerAdapter(elementList, getApplicationContext());
recyclerView.setAdapter(adapter);
} catch (JSONException e) {
e.printStackTrace();
