]
}
Is there any method to filter ?? if yes ..please explain me with code
i want to add the new list to room table...so that i need to cut some unwanted parameters . i don't know how to do that
You need to deserialize JSON to object, for deserialization you can use
com.google.gson add to gradle:
dependencies {
implementation 'com.google.code.gson:gson:2.9.1'
}
create your data class
data class Order(
val id:String,
val name:String,
val image: String,
#SerializedName("subcategory_id")
val subcategoryId: String,
#SerializedName("is_favorite")
val isFavorite: Boolean
)
and finally deserialize your incoming data from network
val responseFromNetwork = getDataFromNetwork() //here you get your json from network
val gson = Gson()
val ordersType = object : TypeToken<List<Order>>() {}.type
val itemList = gson.fromJson<List<Order>>(responseFromNetwork , ordersType)// will be deserialized only field what are in data class another one will be ignored
and finally add to DB your data
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"
}]
}
I am trying to use retrofit with android, which is kind of forcing me to use gson.
I am trying to get the data from the payload["response"]["docs"][0]["web_url"] in my code.
Issue : the key getResponse(), from below model class, always gives me {}. Whats the right way to handle this in android? Also note, the getCopyright() & getStatus() are working fine.
I am also providing the sample payload.
I have the model class like this :
public class ArticleSearchResponseModel {
#SerializedName("status") private String status;
#SerializedName("copyright") private String copyright;
#SerializedName("response") private JSONObject response;
public String getStatus() {
return status;
}
public String getCopyright() {
return copyright;
}
public JSONObject getResponse() {
return response;
}
public void setStatus(String status) {
this.status = status;
}
public void setCopyright(String copyright) {
this.copyright = copyright;
}
public void setResponse(JSONObject response) {
this.response = response;
}
}
My payload :
{
"response": {
"meta": {
"hits": 15987906,
"time": 108,
"offset": 0
},
"docs": [

Before start, I'm not familiar with retrofit.
If you want serialize/unserialize json to pojo, you better make pojo object.
class Response {
Meta meta;
List<Docs> docs;
}
class Docs {
String webUrl;
Mutimedia multimedia;
...
}
The issue the key getResponse(), from below model class, always gives me {} happens because gson cannot determine proper object to convert json to plain old java object.
In order to make your Response model class use http://www.jsonschema2pojo.org/.
Making POJO simple
you no need to make exact structure in model
you can go ahead with your code just need small change
Use
#SerializedName("response") private JsonObject response;
instead of
#SerializedName("response") private JSONObject response;
and in the import
import com.google.gson.JsonObject;
