java - 字符串数组列表转 JSON

Question

我有一个 ArrayList，其中包含如下值

"One"
"Two"
"Three" etc.

我正在尝试从中生成一个 JSON 对象/数组。我的代码如下:

peopleNames = personAdapter.getArrayListNames();
peoplePhones= personAdapter.getArrayListPhones();

JSONNames = new JSONObject();
JSONPhones =  new JSONObject();

for (int i = 0; i < peopleNames.size(); i++){
    try {
        System.out.println(peopleNames.get(i));
        JSONNames.put("Name",peopleNames.get(i));
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

for (int i = 0; i < peoplePhones.size(); i++){
    try {
        JSONPhones.put("Phone",peoplePhones.get(i));
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

jsonArrayNames = new JSONArray();
System.out.println(jsonArrayNames.toString());

但是我的输出只是:

[{"Name":"One"}]

为什么不合并数据？我想，通过你的适配器，你可以直接找到人，对吗？如果是这样，我建议您如下:

people = personAdapter.getPersons();
JSONArray jsonArray = new JSONArray();
for (int i = 0; i < people.size(); i++) {
    JSONObject object = new JSONObject();
    object.put("Name", people.name());
    object.put("Phone", people.phone());
    jsonArray.put(object);
}

生成的 JSON 将是:

[
  {"Name":"One",
   "Phone": "OnePhone"},
  {"Name":"Two",
   "Phone": "TwoPhone"},
]
