Question

我正在提取JSON数据，如下所示

           JsonObjectRequest jor = new  JsonObjectRequest(url, null,
            new Response.Listener<JSONObject>()  {
                @Override
                public void onResponse(JSONObject response) {

                    try{

                        JSONArray ja = response.getJSONArray("results");

                        for(int i=0; i < ja.length(); i++){

                            JSONObject jsonObject = ja.getJSONObject(i);

                            int id = Integer.parseInt(jsonObject.optString("id").toString());
                            String url = jsonObject.getString("resLink");
                            String resType= jsonObject.getString("resType");
                            String name = jsonObject.getString("resName");

                            data += "ResType= "+resType  +" \n URl= "+ url +" \n  id = "+ id + "\n Name = "+ name+"\n\n\n" ;
                           // data +=videoUrl+url;

                        }

                        output.setText(data);


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

我只是获取JSON数据并在文本视图中显示它。我需要的是根据resType在水平滚动视图中显示它们。所有重定型为“image”将在图像滚动视图中视频将在同一屏幕的视频滚动视图中

首先添加这样的模型

    /**
     * Created by waqas.ali on 3/4/2016.
     */
    public class MyModel {
    String name;
    String resType;
    String url;
    int id;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getResType() {
        return resType;
    }
    public void setResType(String resType) {
        this.resType = resType;
    }
    public String getUrl() {
        return url;
    }
    public void setUrl(String url) {
        this.url = url;
    }
}

然后将您的代码替换为

    JSONArray ja = response.getJSONArray("results");
    List<MyModel> myModelList = new ArrayList<MyModel>;
    for(int i=0; i < ja.length(); i++){

    JSONObject jsonObject = ja.getJSONObject(i);
    MyModel mymodel=new MyModel();
    mymodel.id = Integer.parseInt(jsonObject.optString("id").toString());
    mymodel.url = jsonObject.getString("resLink");
    mymodel.resType= jsonObject.getString("resType");
    mymodel.name = jsonObject.getString("resName");

    myModelList.add(mymodel);

    }

然后最后将myModelList传递给你的适配器。

这会让你知道如何去。

如何在Scrollview中放置不同的JSON对象？
