I am not so new to Android, but started using retrofit today, I was able to clear all errors, now the response body returns null. I know its something to do with the way my class is set up. I have no idea how to handle an array with arrays. Any help would be appreciated. Thanks

#GET("/web-api.php?route=feed/web_api/products")

public String getmImageURL() {
return mImageURL;
}
public void setmImageURL(String mImageURL) {
this.mImageURL = mImageURL;
}
#Override
public String toString() {
return mText;
}
}
Just define a Super class -
public class ResponseDS{
public boolean success;
public Product[] products;
}
And use ResponseDS instead of Product class -
#GET("/web-api.php?route=feed/web_api/products")
Call<ResponseDS> loadProducts(#Query("category") Integer id, #Query("key") String apiKey);
Hope it will help :)

On the server there is (as I understand it) an object. It has 2 values - the text and the color of this text. So - I need to get this text and color. At the moment everything is displayed together - TextView is passed the value [{"text": "WE RETURN 10% BONUSES", "textColor": "# 4c82a6"}] ,.
I need to get these values separately
"tag": [
{
"text": "ВЕРНЕМ 10% БОНУСАМИ",

You could create another POJO for the tag instead of using Object.
public class Item {
...
#SerializedName("tag")
#Expose
private Tag tag;
...
}
public class Tag {
#SerializedName("text")
#Expose
private String text;
#SerializedName("textColor")
#Expose
private String textColor;
}
Then you can access the new values with item.getTag().getText(). Or if you'd rather make it appear that the two Tag fields are part of Item, you can create methods that delegate to Tag:
public class Item {
...
public String getText() {
return this.tag.getText();
}
public String getTextColor() {
return this.tag.getTextColor();
}
...
}
I have a json. I have to get source_url into my recyclerView -
[{
"id":3110,
"date":"2020-05-07T18:33:44",
"date_gmt":"2020-05-07T18:33:44",
"modified":"2020-05-07T18:35:37",
"modified_gmt":"2020-05-07T18:35:37",
"_embedded":{
"wp:featuredmedia":[
{
"id":3111,
"date":"2020-05-07T18:33:08",
"slug":"prof-dr-abul-khair",
"source_url":"https:\/\/www.healthmen.com.bd\/wpcontent\/uploads\/2020\/05\/Prof.-Dr.-Abul-Khair-scaled.jpg"
}]
}
}]
I want to get source_url from this JSON
But, here is an array wp:featuredmedia. So that, I followed this process-
Created a class named FeaturedMedia -
public class FeaturedMedia {
#SerializedName("source_url")
#Expose
private String souceurl;
public String getSourceurl(){
return sourceurl;
}
}
Then, I created another class named MediaDetails where I take the FeaturedMedia as a List-
public class MediaDetails{
#SerializedName("wp:featuredmedia")
List<FeaturedMedia> featureMediaList;
public List<FeaturedMedia> getFeaturedMediaList(){
return featuredMediaList;
}}
Then the Model Class-
public class Model{
#SerializedName("id")
#Expose
int id;
#SerializedName("_embedded")
#Expose
MediaDetalis embedded;
public int getId(){
return id;
}
public MediaDetails getEmbedded(){
return embedded;
}}
After all, I created RecyclerViewAdapter to get the data-
public CustomAdapter extends RecyclerView.Adapter<CustomAdapter.CustomAdapterHolder{
List<Model> modelList;
public void onBindViewHolder(#NonNull CustomAdapterHolder holder, int position){
final Model model=modelList.get(position);
int id= model.getId():
String embedded= String.valurOf(model.getEmbedded.getFeaturedMediaList());
}
But, embedded can not get the source_url value. I completed this CustomAdapter. Here I just presented needed code of that adapter. How can I get the source_url value in this RecyclerView?
Your POJO class will be (Respect to given JSON)
public class Model {

#Expose

}
public Embedded getEmbedded() {
return embedded;
}
public void setEmbedded(Embedded embedded) {

Then Embedded class

public List<WpFeaturedmedium> getWpFeaturedmedia() {

}
public void setWpFeaturedmedia(List<WpFeaturedmedium> wpFeaturedmedia) {

I've been searching online and on here and I have been unable to find how exactly to use GSON with my code which is:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_weather_app, container, false);
mRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
mRecyclerView.addItemDecoration(new DividerItemDecoration(mRecyclerView.getContext(), DividerItemDecoration.VERTICAL));
requestJsonObject();
return view;
}
private void requestJsonObject (){
}
How exactly do I add the GSON parsing to my code? I only need the temperature, max, min, weather and humidity?
EDIT:
Here is some more info. I plan on using a normal http connection with an apikey to get my information. I am also planning on using RecyclerView and here is that code:
public class RecyclerViewAdapter extends
RecyclerView.Adapter<RecyclerViewAdapter.CurrentRecycler> {
List<Weather> mCurrentWeatherDataList;
public static class CurrentRecycler extends RecyclerView.ViewHolder{
public TextView location;
public TextView currentTemp;
public TextView currentHumidity;
public TextView currentDescription;
public ImageView currentIcon;
public CurrentRecycler (View view) {
super (view);
location = (TextView) view.findViewById(R.id.current_city_location);
currentTemp = (TextView) view.findViewById(R.id.current_temperature);
currentHumidity = (TextView) view.findViewById(R.id.current_humidity);
currentDescription = (TextView) view.findViewById(R.id.current_weather_description);
currentIcon = (ImageView) view.findViewById(R.id.current_weather_icon);
}
}
public RecyclerViewAdapter (List<Weather> mCurrentWeatherDataList) {
this.mCurrentWeatherDataList = mCurrentWeatherDataList;
}
#Override
public CurrentRecycler onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_item, parent, false);
final CurrentRecycler currentRecycler = new CurrentRecycler(view);
return currentRecycler;
}
#Override
public void onBindViewHolder( CurrentRecycler holder, int position) {
final Weather currentRecycler = mCurrentWeatherDataList.get(position);
holder.location.setText(currentRecycler.getDefaultLocation());
holder.currentTemp.setText((currentRecycler.getDefaultCurrentTemp()));
holder.currentHumidity.setText(currentRecycler.getDefaultHumidity());
holder.currentDescription.setText(currentRecycler.getDefaultDescription());
}
#Override
public int getItemCount() {
return mCurrentWeatherDataList.size();
}
}
In your requestJsonObject method, use volley or okhttp to fetch the weather data from API.
Once you get the data as a String, you can use the following code:
List list = new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create().fromJson(str, List.class);
Main main = list.getDt();
main.getTemp();
main.getTempMin();
main.getTempMax();
str means your api response data. List means your first entity class.
Moreover, I strongly recommend you to rename your class name, never try to use the reserved name of Java, make them meaningful.
I have a model class "JobPostBean" which I'm initiating in another model class and adding data using the second model class. I would like to clear any data which gets saved in the "JobPostBean" class. Is there any way to clear it either in "JobPostBean" class or in the second model class where its initialised? I would prefer to clear it using a single method rather than setting every item in the "JobPostBean" class to null.

Content.class and CountryRelated.class have same structure
after i do article.save() my lists doesnt save . Am i doing something wrong or it doesnt save lists at all ???
I few things to look at.
First. I do not believe that the database will handle a column with the type of List or a type of other Object. When I tried running your code, I received:
Class cannot be read from Sqlite3 database. Please check the type of field categories(java.util.List)
These should be types the database can store. Try serializing your List(s) to Strings to insert them in the db. You can try doing this in your getter and setter. The setter takes the list of objects and converts it to a serialized String, the getter takes the serialized String and converts it back to a list of objects.
In the instance of SugarOrm, you can reference another table and it will create a relationship outlined here:
http://satyan.github.io/sugar/creation.html#why
Notice the "Author" type is just referencing a record from another table in the database.
Second I usually try and set my default values inside my default constructor. so something like:
... property declarations...
public Article() {
this.name = "Default Value";
}
Hope this helps you finish troublshooting!
