Question

我一直在尝试所有给出JSON响应的内容，并在Android中使用它。

[{
    "id": "001",
    "firstName": "Mark",
    "lastName": "Mason",
    "role": "CEO",
    "profileImageURL": "http://developers.mub.lu/resources/profilePlaceholder.png"

    }]
}]

基本上我想在Recyclerview中显示所有属于团队的人。即

"teamName":"iOS","teamName" : "Android","teamName" : "Android","Web" : "Design"

尝试了这个：

   package testing.theo.androidtestproject.fragment;



public class TestingFragment extends Fragment {
public static final String IMAGE_URL =  
"http://developers.mub.lu/resources/";
private ArrayList<Model> modelArrayList;
private RecyclerView mRecyclerView;
private MyAdapter myAdapter;

public TestingFragment() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View v = inflater.inflate(R.layout.fragment_testing, container, false);

    modelArrayList = new ArrayList<>();

    mRecyclerView = (RecyclerView)v.findViewById(R.id.recycler_view);

    final LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
    mRecyclerView.setHasFixedSize(true);
    mRecyclerView.setLayoutManager(linearLayoutManager);

    myAdapter = new MyAdapter(getActivity(),modelArrayList);
    mRecyclerView.setAdapter(myAdapter);

    showTestData();
    return v;


}

public void showTestData()
  {



   // Request a string response from the provided URL.
   final JsonArrayRequest jsObjRequest = new JsonArrayRequest(Request.Method.GET, URLClass.URL, new Response.Listener<JSONArray>() {

       @Override
       public void onResponse(JSONArray response) {
           Log.d("Theo", response.toString());

           for(int i = 1;i<response.length();i++){


               try {


                   JSONObject jsonObject = response.getJSONObject(i);


                       JSONArray teamMembersArray = 
        jsonObject.getJSONArray("members");
                       for(int j=0;j<teamMembersArray.length();j++){
                           Model m = new Model();

                           JSONObject teamObject = teamMembersArray.getJSONObject(i);
                           m.setFirstName(teamObject.getString("firstName"));
                           m.setLastName(teamObject.getString("lastName"));
                           m.setRole(teamObject.getString("role"));
                           modelArrayList.add(m);
                       }



               } catch (JSONException e) {
                   e.printStackTrace();
               }

           }


           //modelArrayList.add(m);
           // Update list by notifying the adapter of changes
           myAdapter.notifyDataSetChanged();
       }
   }, new Response.ErrorListener() {
       @Override
       public void onErrorResponse(VolleyError error) {

           //hidePD();
       }
   });
   AppController.getInstance().addToRequestQueue(jsObjRequest);

 }

 }

现在我为每个成员都命名相同。:(

Answer 1

几乎没有变化：你不需要第二次循环，不需要检查物体的长度。在内循环中重置Model。

试试这个

for(int i = 1;i<response.length();i++){ // skipping first object as you said
    try {
        JSONObject jsonObject = response.getJSONObject(i);
        //m.setRole(jsonObject.getString("teamName"));

        JSONArray teamMembersArray = jsonObject.getJSONArray("members");
        for(int j=0;j<teamMembersArray.length();j++){
            JSONObject teamObject = teamMembersArray.getJSONObject(j);
            Model m = new Model(); // reset model in inner loop
            m.setFirstName(teamObject.getString("firstName"));
            m.setLastName(teamObject.getString("lastName"));
            m.setRole(teamObject.getString("role"));
            modelArrayList.add(m);
        }

    } catch (JSONException e) {
        e.printStackTrace();
    }
}

Answer 2

跳过开始循环的第一个元素1.
我也改变了你的循环以使用正确的变量，让我知道它是否有效：

 @Override
 public void onResponse(JSONArray response) {
     Log.d("Theo", response.toString());

     for(int i = 1;i<response.length();i++){
     // i = 1 skips the first element

         try {
             JSONObject jsonObject = response.getJSONObject(i);
             JSONArray teamMembersArray = jsonObject.getJSONArray("members");

             for(int j=0;j<teamMembersArray.length();j++){
                 Model m = new Model();
                 JSONObject teamObject = teamMembersArray.getJSONObject(j);
                 m.setFirstName(teamObject.getString("firstName"));
                 m.setLastName(teamObject.getString("lastName"));
                 m.setRole(teamObject.getString("role"));
                 modelArrayList.add(m);
             }
         } catch (JSONException e) {
             e.printStackTrace();
         }
     }
}

凌乱的JSON响应，给我带来了麻烦
