Linking Two Different Objects For ArrayList - android

I have two classes:
Driver Class:
public static final class Driver implements DriverColumns, BaseColumns, Parcelable {
public static final Uri CONTENT_URI = BASE_CONTENT_URI.buildUpon().appendPath(PATH_DRIVERS).build();
public static final String CONTENT_TYPE = "vnd.android.cursor.dir/com.test.console.drivers";
public static final String CONTENT_ITEM_TYPE = "vnd.android.cursor.item/vnd.console.drivers";
private int driver_id, driver_number;
private String driver_name;
public Driver() {
}
public Driver(int driverID, int driverNumber, String driverName) {
this.setDriverID(driverID);
this.setDriverNumber(driverNumber);
this.setDriverName(driverName);
}
public static Uri buildDriverUri(String driverID) {
return CONTENT_URI.buildUpon().appendPath(driverID).build();
}
public int getDriverID() {
return driver_id;
}
public void setDriverID(int driver_id) {
this.driver_id = driver_id;
}
public int getDriverNumber() {
return driver_number;
}
public void setDriverNumber(int driver_number) {
this.driver_number = driver_number;
}
public String getDriverName() {
return driver_name;
}
public void setDriverName(String driver_name) {
this.driver_name = driver_name;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(driver_id);
dest.writeInt(driver_number);
dest.writeString(driver_name);
}
private Driver(Parcel in) {
this.driver_id = in.readInt();
this.driver_number = in.readInt();
this.driver_name = in.readString();
}
public static final Parcelable.Creator<Driver> CREATOR = new Parcelable.Creator<Driver>() {
#Override
public Driver createFromParcel(Parcel source) {
return new Driver(source);
}
#Override
public Driver[] newArray(int size) {
return new Driver[size];
}
};
}
and a Vehicle Class:
public static final class Vehicle implements VehicleColumns, BaseColumns, Parcelable {
public static final Uri CONTENT_URI = BASE_CONTENT_URI.buildUpon().appendPath(PATH_VEHICLES).build();
public static final String CONTENT_TYPE = "vnd.android.cursor.dir/com.test.console.vehicles";
public static final String CONTENT_ITEM_TYPE = "vnd.android.cursor.item/vnd.console.vehicles";
private int vehicle_id, vehicle_number;
private String vehicle_vin;
public Vehicle() {
}
public Vehicle(int vehicleID, int vehicleNumber, String vehicleVin) {
setVehicleID(vehicleID);
setVehicleNumber(vehicleNumber);
setVehicleVin(vehicleVin);
}
public int getVehicleID() {
return vehicle_id;
}
public void setVehicleID(int mVehicleID) {
this.vehicle_id = mVehicleID;
}
public int getVehicleNumber() {
return vehicle_number;
}
public void setVehicleNumber(int mVehicleNumber) {
this.vehicle_number = mVehicleNumber;
}
public String getVehicleVin() {
return vehicle_vin;
}
public void setVehicleVin(String mVehicleVin) {
this.vehicle_vin = mVehicleVin;
}
public static Uri buildVehicleUri(String vehicleID) {
return CONTENT_URI.buildUpon().appendPath(vehicleID).build();
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(vehicle_id);
dest.writeInt(vehicle_number);
dest.writeString(vehicle_vin);
}
private Vehicle(Parcel in) {
this.vehicle_id = in.readInt();
this.vehicle_number = in.readInt();
this.vehicle_vin = in.readString();
}
public static final Parcelable.Creator<Vehicle> CREATOR = new Parcelable.Creator<Vehicle>() {
#Override
public Vehicle createFromParcel(Parcel source) {
return new Vehicle(source);
}
#Override
public Vehicle[] newArray(int size) {
return new Vehicle[size];
}
};
}
I'm trying to Link them together so I can use them in an ArrayList.
Basically Have a List of:
Driver + Vehicle
Not sure if I should have a superclass? Because i've read that we can't do something like this:
ArrayList<Driver,Vehicle> drivers_vehicles = new ArrayList<Driver,Vehicle>
I will need to Sort the list by driver_number in the Driver class.
How can I accomplish this?
Thanks..

You should make a new type uniting both driver and vehicle. I.e.
public class DriverVehiclePair implements Comparable<DriverVehiclePair> {
public Driver driver;
public Vehicle vehicle;
public int compareTo(DriverVehiclePair compareObject)
{
if (driver.driver_number < compareObject.driver_number)
return -1;
else if (driver_number == compareObject.driver_number)
return 0;
else
return 1;
}
...
}
Then you make a list of your new type and sort it like this
List<DriverVehiclePair> list = new ArrayList<DriverVehiclePair>();
// fill your list with data here (with proper arguments in constructors - I don't send any data below
list.add(new DriverVehiclePair(new Driver(), new Vehicle()));
// and finally sort it
Collections.sort(list);
You might want to take a read on Comparable interface

Now Basically I want to acess someting like response.getData().... But there is no such option.
Possibly data not accessible, because it is private. Try to crete getter method.
public class GenericResponse<T> {
#JsonProperty("status")
private String status;
#JsonProperty("message")
private String message;
#JsonProperty("data")
private T data;
public T getData() {
return data;

Pass ArrayList of Parcelable objects throws error

I have an object with a couple of Strings, one int and another object which has 4 inner objects. All of them implementing Parcelable. In order to generate the boilerplate code, I used Parcelable plugin from Android studio.
Even though all the objects are parcelable, I'm getting the following error: android.os.BadParcelableException: ClassNotFoundException when unmarshalling: AlbumTrackResponse
Here's how the POJOs look like:
Main object:
public class AlbumTrackResponse implements Parcelable {
private String id;
private String albumId;
private String position;
private String title;
private int rate;
private AllServices services;
public AllServices getServices() {
return services;
}
public void setServices(AllServices services) {
this.services = services;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getAlbumId() {
return albumId;
}
public void setAlbumId(String albumId) {
this.albumId = albumId;
}
public String getPosition() {
return position;
}
public void setPosition(String position) {
this.position = position;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public int getRate() {

};
}
The inner objects from here contain just string items.
Here's how I pass the ArrayList to the bundle:
bundle.putParcelableArrayList(MediaPlayerService.TRACK_LIST, trackList);
I'm passing the items from an Activity to a Service. Any ideas why I'm getting this error?
EDIT: Implementation of service classes
public class GoogleService implements Parcelable {
private String name;
private String uri;
public String getUri() {
return uri;
}
public void setUri(String uri) {
this.uri = uri;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
protected GoogleService(Parcel in) {
name = in.readString();
uri = in.readString();
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeString(uri);
}
#SuppressWarnings("unused")
public static final Parcelable.Creator<GoogleService> CREATOR = new Parcelable.Creator<GoogleService>() {
#Override
public GoogleService createFromParcel(Parcel in) {
return new GoogleService(in);
}
#Override
public GoogleService[] newArray(int size) {
return new GoogleService[size];
}
};
}
This looks extremly strange
this.services = in.readParcelable(getClass().getClassLoader());
You are pointing out to the wrong class loader. You have to use it like this
this.services = (AllServices)in.readParcelable(AllServices.class.getClassLoader());
Besides that, I am always using this site http://www.parcelabler.com/ to quickly generate my Parceables. Or you could use it like this
services = (AllServices) in.readValue(AllServices.class.getClassLoader());
Here:
protected AllServices(Parcel in) { this.gigrev = in.readParcelable(getClass().getClassLoader());
this.apple = in.readParcelable(getClass().getClassLoader());
this.google = in.readParcelable(getClass().getClassLoader());
this.spotify = in.readParcelable(getClass().getClassLoader()); }
Replace it with
protected AllServices(Parcel in) { this.gigrev = in.readParcelable(GigRevService.class.getClassLoader());
this.apple = in.readParcelable(AppleService.class.getClassLoader());
this.google = in.readParcelable(GoogleService.class.getClassLoader());
this.spotify = in.readParcelable(SpotifyService.class.getClassLoader()); }
And replace:
this.services = in.readParcelable(getClass().getClassLoader());
With:
this.services = in.readParcelable(AllServices.class.getClassLoader());
Also can you show the GoogleService etc classes? Each inner object's class must have a Parcelable creator also and implement the Parcelable interface as well.

Put two parcelable inside same intent

Folks, I'm getting mad with parcelables.
Here goes, I have these lines:
Intent i = new Intent(context, PaymentDetailsActivity.class);
i.putExtra(ConstantsUtils.PARAM_INTENT_ORDER_DETAILS, responseOrderInfoApiModel);
i.putExtra(ConstantsUtils.PARAM_INTENT_PAYMENT_INFO, paymentInfoViewModel);
startActivity(i);
and here I receive my parcelables:
Intent receivedIntent = getIntent();
responseOrderInfoApiModel = receivedIntent.getParcelableExtra(ConstantsUtils.PARAM_INTENT_ORDER_DETAILS);
paymentInfoViewModel = receivedIntent.getParcelableExtra(ConstantsUtils.PARAM_INTENT_PAYMENT_INFO);
The point is, responseOrderInfoApiModel is receiving a null, but it shouldn't, however if I comment the line:
i.putExtra(ConstantsUtils.PARAM_INTENT_PAYMENT_INFO, paymentInfoViewModel);
My responseOrderInfoApiModel receive the correct value.
Here goes my parcelables:

Try using bundle and put your data in bundle and then put bundle in to intent. Once i had such a funny problem and this method solved my problem.

readParcelable returns null

I try to pass a News class to an activity, so I implemented the Parcelable interface. Inside News I have two classes implementing Parcelable too, Image and Date
The matter is that my News object at the end contains null for fields image and date.
Here my code:
News.java
public class News implements Parcelable {
public static final String TAG = "model_news";
private JSONObject object;
private int id;
private String type;
private String title;

private Date date;
private Boolean is_video;
public News(JSONObject object) {
this.object = object;
try {
id = Integer.parseInt(object.getString("id"));
type = object.getString("type");
title = object.getString("title");
comment_disabled = object.getBoolean("comment_disabled");
category_name = object.getString("category_name");
url = object.getString("url");
if (!object.isNull("images")) {
images = new Image(object.getJSONObject("images"));
}
date = new Date(object.getJSONObject("date"));
is_video = object.getBoolean("is_video");
} catch (JSONException e) {
Log.e(TAG, e.getMessage());
}

what I'm doing wrong ?
There is mistake in the Parcelable implementation.
First of all parcelable implementation states that: the fields passed in News(Parcel in) Constructor should be written in the same sequence in writeToParcel() method. Thats called Marshalling and Unmarshalling.
Corrections:
Drawable cannot be passed a parameter in Parcelable.
News Parcelable implementation.
Missed some of the fields its just for your understanding.
public class News implements Parcelable {
public static final String TAG = "model_news";
private JSONObject object;
private int id;
private String type;
private String title;
private Boolean comment_disabled;
private String category_name;
private String url;
private Image images;
private Date date;
private Boolean is_video;
protected News(Parcel in) {
id = in.readInt();
type = in.readString();
title = in.readString();
category_name = in.readString();
url = in.readString();
}
public static final Creator<News> CREATOR = new Creator<News>() {
#Override
public News createFromParcel(Parcel in) {
return new News(in);
}
#Override
public News[] newArray(int size) {
return new News[size];
}
};
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(id);
dest.writeString(type);
dest.writeString(title);
dest.writeString(category_name);
dest.writeString(url);
}
}
public class Image implements Parcelable {
public static final String TAG = "model_image";

Not able to pass parcelable object ArrayList to a fragment activity

I have a Activity A which has a ArrayList of object which i parceable..
Object is :
public class DashBoardPOJO implements Parcelable {
private String dashBoardName;
private String dashBoardId;
private String dashBoardStatus;
private ArrayList<DashBoardDataPOJO> dashBoardDataList;
private boolean loaded;
public ArrayList<DashBoardDataPOJO> getDashBoardDataList() {
return dashBoardDataList;
}
public void setDashBoardDataList(
ArrayList<DashBoardDataPOJO> dashBoardDataList) {
this.dashBoardDataList = dashBoardDataList;
}
public boolean isLoaded() {
return loaded;
}
public void setLoaded(boolean loaded) {
this.loaded = loaded;
}
public String getDashBoardStatus() {
return dashBoardStatus;
}
public void setDashBoardStatus(String dashBoardStatus) {
this.dashBoardStatus = dashBoardStatus;
}
#Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(dashBoardName);
dest.writeString(dashBoardId);
dest.writeList(dashBoardDataList);
}
public static final Parcelable.Creator<DashBoardPOJO> CREATOR = new Parcelable.Creator<DashBoardPOJO>() {
public DashBoardPOJO createFromParcel(Parcel in) {
return new DashBoardPOJO(in);
}
public DashBoardPOJO[] newArray(int size) {
return new DashBoardPOJO[size];
}
};
public DashBoardPOJO() {
dashBoardName = null;
dashBoardId = null;
dashBoardDataList = null;
/*
* userName=null; userId=null;
*/
}
private DashBoardPOJO(Parcel in) {
dashBoardName = in.readString();
dashBoardId = in.readString();
in.readList(dashBoardDataList, null);
}
// GETTERS AND SETTERS............
public String getDashBoardName() {
return dashBoardName;
}
public void setDashBoardName(String dashBoardName) {
this.dashBoardName = dashBoardName;
}
public String getDashBoardId() {
return dashBoardId;
}
public void setDashBoardId(String dashBoardId) {
this.dashBoardId = dashBoardId;
}
}
I want to pass the ArrayList to a activity which extends Fragment Activity.
I am sending the object like this
Intent intent = new Intent(
DashboardActivity.this,
BaseFragmentActivity.class);
intent.putParcelableArrayListExtra("dashBoardList", dashBoardList);
startActivity(intent);
And receiving it at the fragment activity like this
dashboardList = getIntent().getExtras().getParcelableArrayList("dashBoardList");
But still the intent is returninig me a null value... Pls help...
Try this:
private DashBoardPOJO(Parcel in) {
dashBoardName = in.readString();
dashBoardId = in.readString();
dashBoardDataList = (ArrayList<DashBoardDataPOJO>) in.readArrayList(DashBoardDataPOJO.class.getClassLoader());
}
