Android创建JSON格式数据

作为上一篇博客的补充，简单那讲解了一下Android创建JSON格式数据的小Demo。

1. 创建JSON格式数据

对于Android创建JSON格式数据，由于Android官方提供了相应了put(key, value)等方法，因此代码十分简单，如下所示：

JSONObject jsonObject = new JSONObject();
JSONArray jsonArray = new JSONArray();
JSONObject object_1 = new JSONObject();
JSONObject object_2 = new JSONObject();
JSONObject object_3 = new JSONObject();

try {
    object_1.put("id", 1);
    object_1.put("ide", "eclipse");
    object_1.put("name", "Java");
    object_2.put("id", 2);
    object_2.put("ide", "XCode");
    object_2.put("name", "Swift");
    object_3.put("id", 3);
    object_3.put("ide", "Visual Studio");
    object_3.put("name", "C#");

    jsonArray.put(object_1);
    jsonArray.put(object_2);
    jsonArray.put(object_3);

    jsonObject.put("languages", jsonArray);
    jsonObject.put("cat", "it");

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

Log.i("TESTJSON", jsonObject.toString());

最后打印出来的Log日志信息为：

{"languages":[{"id":1,"ide":"eclipse","name":"Java"},{"id":2,"ide":"XCode","name":"Swift"},{"id":3,"ide":"Visual Studio","name":"C#"}],"cat":"it"}
