java - 如何解析JSON数组对象textview 1和textview 2

Question

我的代码适用于将 json 对象解析为单个 TextView ，现在我想更改它以将第一个对象解析为文本 Response，将第二个对象解析为文本 Response2这就是为什么我将 for 循环更改为 i < = 1，这样我只能从数组中获取前 2 个结果，而不需要其余的结果。 for 循环适用于 1 个字段，但我认为我的 if/else 循环有问题

try {
        // Parsing json array response
        // loop through each json object
        jsonResponse = "";
        jsonResponse2 ="";
        for (int i = 0; i <= 1; i++) {
          //int i  <= 1
            JSONObject person = (JSONObject) response
                            .get(i);

            String name = person.getString("name");

                if (i <=0){

                    jsonResponse += "Name: " + name + "\n\n";
                }

                else { jsonResponse2 += "Name: " + name + "\n\n";}

                }

            txtResponse.setText(jsonResponse);
            txtResponse2.setText(jsonResponse2);

这可以解决您的问题吗:

                String name1,name2,name3,name4;
                JSONArray jArray=new JSONArray(result);
                for(int i=0;i<jArray.length();i++){
                    if(i==0){
                        name1=jArray.getJSONObject(i).getString("name");
                        Log.e("Name First", name1);
                    }else if(i==1){
                        name2=jArray.getJSONObject(i).getString("name");
                        Log.e("Name Second", name2);
                    }else if(i==2){
                        name3=jArray.getJSONObject(i).getString("name");
                        Log.e("Name Third", name3);
                    }else if(i==3){
                        name4=jArray.getJSONObject(i).getString("name");
                        Log.e("Name Four", name4);
                    }
                }
               // txtResponse.setText(name1);
               // txtResponse2.setText(name2);

其中“result”是您的 json 数组字符串。
