我想以表格形式将回收者视图数据列表发布到服务器上
i want to post my recycler view data list to server in form
[
{movie_name :
movie_Add :
movie_no:
}
{movie_name :
movie_Add :
movie_no:
}
{movie_name :
movie_Add :
movie_no:
}
]
推荐答案
List<String> movieList; //you can define it to globally
movieList=new ArrayList<>();
movieList.add("1");
movieList.add("2");
movieList.add("3");
JSONArray movieArray = new JSONArray();
for(int i=0; i<movieList.size(); i++) {
JSONObject movieObject = new JSONObject();
try {
movieObject.put("movie_name", "" + movieList.get(i).toString());
movieArray.put(movieObject);
} catch (JSONException e) {
e.printStackTrace();
}
}
Log.d("--------------------", String.valueOf(movieArray));
尝试
输出:
D/--------------------: [{"movie_name":"1"},{"movie_name":"2"},{"movie_name":"3"}]
