我试图表示列表视图即JSONArray用户数据来自Facebook的图形API响应，显示在列表视图机器人JSONArray数据 - 的Facebook API

下面是我想要的代码：

    try 
        { 
         JSONObject resObject = response.getJSONObject(); 
         JSONArray jsonArray = resObject.getJSONArray("data"); 
         for (int i = 0; i < jsonArray.length(); i++) { 
          JSONObject jsonObject = jsonArray.getJSONObject(i); 
          if(jsonArray.getJSONObject(i).has("likes")) 
          { 
           JSONObject jsonObjectlikes = jsonObject.getJSONObject("likes"); 
           JSONArray jsonArrayLikeData = jsonObjectlikes.getJSONArray("data"); 
           for (int j = 0; j < jsonArrayLikeData.length(); j++) { 
            JSONObject jsonObjectlike = jsonArrayLikeData.getJSONObject(j); 
            String listid = jsonObjectlike.getString("id"); 
            String listname = jsonObjectlike.getString("name"); 
            HashMap<String, String> contact = new HashMap<>(); 
            contact.put("id", listid); 
            contact.put("name", listname); 
            contactList.add(contact); 
           } 
          } 
          ListAdapter adapter = new SimpleAdapter(
            MainActivity.this, contactList, 
            R.layout.activity_listview, new String[]{"id", "name"}, new int[]{R.id.id, 
            R.id.name}); 
          simpleList.setAdapter(adapter); 
         } 
        }

这里是JSON：

{ 
    "data": [ 
     { 
     "id": "xxxxxxxxxxxxxxxxxxxxxxxxxxx", 
     "likes": { 
      "data": [ 
       { 
        "id": "xxxx", 
        "name": "xxx" 
       } 
      ], 
     } 
     } 
    ] 
}

上面的代码变得喜欢数据，我想表现出简单的ListView这个数据。

回答：

试试这个

添加contactList=new ArrayList<>();

SimpleAdapter适配器=新SimpleAdapter（ MainActivity.this，contactList， R.layout.activity_listview，新的String [] { “ID”，“命名“}，新INT [] {R.id.id， R.id.name}）;

试试这个代码

public void GetFacebookData() { 
contactList=new ArrayList<>(); 
Bundle parameters = new Bundle(); 
parameters.putString("fields", "likes"); 
parameters.putString("limit", "50"); 
new GraphRequest(
     AccessToken.getCurrentAccessToken(), 
     "/me/posts", 
     parameters, 
     HttpMethod.GET, 
     new GraphRequest.Callback() { 
      public void onCompleted(GraphResponse response) { 
       //Log.v("TAG", "Facebook Photos response: " + response); 
       try 
       { 
        JSONObject resObject = response.getJSONObject(); 
        JSONArray jsonArray = resObject.getJSONArray("data"); 
        for (int i = 0; i < jsonArray.length(); i++) { 
         JSONObject jsonObject = jsonArray.getJSONObject(i); 
         Log.i("ID", "-->" + jsonObject.getString("id")); 
         if(jsonArray.getJSONObject(i).has("likes")) 
         { 
          JSONObject jsonObjectlikes = jsonObject.getJSONObject("likes"); 
          JSONArray jsonArrayLikeData = jsonObjectlikes.getJSONArray("data"); 
          for (int j = 0; j < jsonArrayLikeData.length(); j++) { 
           JSONObject jsonObjectlike = jsonArrayLikeData.getJSONObject(j); 
           String listid = jsonObjectlike.getString("id"); 
           String listname = jsonObjectlike.getString("name"); 
           HashMap<String, String> contact = new HashMap<>(); 
           contact.put("id", listid); 
           contact.put("name", listname); 
           contactList.add(contact); 
           Log.i("Like ID", "-->" + jsonObjectlike.getString("id")); 
           Log.i("Like Name", "-->" + jsonObjectlike.getString("name")); 
          } 
         } 
         SimpleAdapter adapter = new SimpleAdapter(
           MainActivity.this, contactList, 
           R.layout.activity_listview, new String[]{"id", "name"}, new int[]{R.id.id, 
           R.id.name}); 
         simpleList.setAdapter(adapter); 
        } 
       } 
       catch (JSONException e) 
       { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
      } 
     }).executeAsync(); 
}
