从JSON对象解析字符串数组
问题描述：
这可能太简单了，但我只是无法找到解决方案.如何直接从JSON对象中解析string array?
It might be too easy but I just cannot find a solution to this. How can I directly parse the string array out of the JSON object?
例如，
json = {"names":["John", "Alex", "David"]}
我无法执行json.getJSONArray("names")，因为它没有返回string array.
I cannot do json.getJSONArray("names") since it doesn't return a string array.
答
您可以将数据作为json数组并通过其循环以创建列表
You can get the data as a json array and the loop through it to create a list
JSONObject jsonObject = new JSONObject("{names:['1','2','3']}");
JSONArray jsonArray = jsonObject.getJSONArray("names");
List<String> names = new ArrayList<String>();
for(int i = 0; i < jsonArray.length(); i++){
names.add(jsonArray.getString(i));
}
System.out.println(names);
