I am getting multiple fields dynamically from JSON data. To save data of dynamic fields into web services i prefer to call by id. But i unable to get the id of that fields. So I need to know how to get ids of dynamic fields.
Here is my JSON response:
{
"sections": [
{
"head": "Section A",
"sort": 1,
"section_id": 3,
"cols": "2",
"fields": [
{
"id": 5,
"template_id": 2,
"section_id": 3,
"label": "A1",
"itype": "1",
"idefault": "",
"ioptions": "",
"required": "N",
"ivalids": "0",
"sort": 1,
"created_at": "-0001-11-30 00:00:00",
"updated_at": "2018-09-23 05:32:59",
"deleted_at": null
},
{
"id": 6,
"template_id": 2,
"section_id": 3,
"label": "A2",
"itype": "1",
"idefault": "",
"ioptions": "",
"required": "N",
"ivalids": "0",
"sort": 1,
"created_at": "-0001-11-30 00:00:00",
"updated_at": "2018-09-23 05:32:59",
"deleted_at": null
}
]
}
]
}
If "itype"=1 dynamic_field = edittext, "itype"=2 dynamic_field =
spinner and so on.
In my response, I am getting "itype"=1 so i am dynamically displaying two edit texts.
And "label" from JSON used as id for a dynamic field. If I integrate API, it's getting the error as "can't resolve the id".
I don't know how to resolve this error.

This is my first android project (I'm a php developer) but i'm struggling to see how to take this example which uses a nested structure under data for the json array whereas my data is not double nested like this example.
The excample code I am trying to modify is from here https://github.com/datanapps/RetrofitKotlin and the key differences in the json are todo with the nesting.
Original
{
"page": 1,
"per_page": 6,
"total": 12,
"total_pages": 2,

whereas mine is simply

Specifically I want to query the SGV values, direction and date

You "return type" of "method" in Retrofit "interface" will be:
List<MyModel>
And MyModel:
data class MyModel(val _id:String, val device:String,...)
I want to know how to filter data. I got data with category name but cannot filter category wise.Here is my data:
{
"TITLE": "tea",
"PRICE": "17",
"QTY": "1",
"CAT_ID": "33",
"CAT_NAME": "POPULAR PRODUCTS",
"TYPE": "veg"
},
{
"TITLE": "Coffee",
"PRICE": "102",
"QTY": "1 ",
"CAT_ID": "8",
"CAT_NAME": "MORNING SPECIAL",
"TYPE": "veg"
},
{
"TITLE": "Jeera chachh",
"PRICE": "42",
"QTY": "1",
"CAT_ID": "33",
"CAT_NAME": "POPULAR PRODUCTS",
"TYPE": "veg"
},
{
"TITLE": "Roti Ghee Wali",
"PRICE": "21",
"QTY": "1",
"CAT_ID": "33",
"CAT_NAME": "POPULAR PRODUCTS",
"TYPE": "veg"
},
{
"TITLE": "Paneer paratha",
"PRICE": "102",
"QTY": "1 ",
"CAT_ID": "8",
"CAT_NAME": "MORNING SPECIAL",
"TYPE": "veg"
},
{
"TITLE": "Mix paratha",
"PRICE": "102",
"QTY": "1",
"CAT_ID": "8",
"CAT_NAME": "MORNING SPECIAL",
"TYPE": "veg"
},
I already parse the data but not able to set in fragment according to category.Can anyone solve my issue.
Step 1: Store the data in database.
Step 2: Search
select * from table where CAT_NAME = 'your_filter_category'.
or better ....CAT_NAME like %your_filter_category%.
In Case of no database;
Store the Data in list.
HashMap<String, ArrayList<Item>> map = new HashMap<>();
ArrayList<Item> itemList = new ArrayList<>();
Loop on List{
Item item = fromLoop index;
if(map.contains(item.getCat())){
itemList = map.get(item.getCat());
itemList.put(item);
map.put(item.getCat(),itemList);
}else{
itemList.clear();
itemList.put(item);
map.put(item.getCat(),itemList);
}
}
//after loop you will get HashMap with keys as categories and Values as the list of selected key category.
Step 3: Publish the results.
Note: No one will do your homework here. the only thing we can do for you, we can assist you how to do.
enter your code to: JSON Formatter and you will see that something is invalid in your JSON, it has multiple root elements. Maybe you should store whole code in JSONArray like this: `
{
"features":
[{
"TITLE": "tea",
"PRICE": "17",
"QTY": "1",
"CAT_ID":"33",
"CAT_NAME": "POPULAR PRODUCTS",
"TYPE": "veg" },
{
"TITLE":"Coffee",
"PRICE": "102",
"QTY": "1 ",
"CAT_ID": "8",
"CAT_NAME":"MORNING SPECIAL",
"TYPE": "veg"
}]
}

This data is of just one user. I have 50 of them.
I am still in learning stage and what I have done is that I have successfully listed all user in an activity. Now what I want to do is when I click on a user it should show it's related details in next activity...
List Users->Select Users->Show selected user details
I still don't know how to send data to other activity and display it.
I have a json response that looks somewhat like this.

There is a many to many relationship between users and groups.
I am using retrofit with the GsonConverterFactory. On response, how can I parse this information into objects?
I tried making a User class , and a group class, then I put an array of groups as a member of the user class.
But when I access User.getGroups().get(1).getID , it returns 0.
However, User.getGroups().size() does return 4 (the correct number in this case)
How can I achieve this in retrofit?
A practical tool to parse JSON correctly with retrofit can be to generate the classes with http://www.jsonschema2pojo.org
You just have to put the example JSON, the resource type in JSON and put the desired annotation style (GSON, Jackson, ..).

I have to check the online/offine status of a user using online key inside the userInfo object.I am using the following code :
JSONObject userInfo = object.getJSONObject("userInfo");
Boolean online = userInfo.getBoolean("online");
Log.e("Online",online);
When i tried to use this statement :
Log.e("online1", (String) userInfo.get("online"));
It gives me the error that java.lang.ClassCastException: java.lang.Boolean cannot be cast to java.lang.String .
So it is sure that userInfo.get("online") is returning me some boolean value.So when i use this :
Log.e("online1", String.valueOf(userInfo.getBoolean("online")));
it gives me always false but i know i am getting true value from server in some cases.Please help me to fix the issue
Are you certain the get() function returns a boolean. I am not certain about the JSON library with Android but ones I have used will return the value as a string for which you then need to parse using Boolean.parseBoolean(value).
Hope that helps.
You can try
Boolean online = Boolean.parseBoolean(userInfo.getString("online"))
This is worked for me.
you try boolean online = userInfo.getBoolean("online"); instead of Boolean online = userInfo.getBoolean("online");
I'd recommend using the opt version instead of the get version.
The main difference is that opt will not throw a JSONException and stop parsing.
Try therefore to replace all of your getXXX() by optXXX().
Another upside is that with opt, you can specify a fallback value.
Log.e("Online", online.toString());
It takes only String.
The method e(String, String) in the type Log is not applicable for the arguments (String, boolean).
