Spaceghost87 :
i need to implement the Parcelable interface in a Realm model but i have no idea how to write a RealmList in a Parcel
here is my code:
public class SomeModel extends RealmObject implements Parcelable {
public long id;
public RealmList<SomeOtherModel> otherModels;
protected SomeModel(Parcel in) {
id = in.readLong();
//here i need to otherModel RealmList from parcel
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeLong(id);
// here i need to write the otherModels RealmList
}
//other methods omitted
}
pd: the SomeOtherModel class also implements the Parcelable interface and extends RealmObject

Actually you can
Firstly we are talking about un-managed entities.
Then you need to initialize realmList with new RealmList<>() . Then add data to it as collection with addAll method.That's it!
Here is a sample:
Person.java:
package com.entity;
import android.os.Parcel;
import android.os.Parcelable;
import java.util.ArrayList;
import io.realm.RealmList;
/**
* Person
* Created by Maher Abuthraa on 6/9/17.
*/
public class Person implements Parcelable {
@PrimaryKey
private long id;
private String name;
private RealmList<Dog> mRealmList;
public Person() {
}
public Person(long id, String name) {
this.id = id;
this.name = name;
}
public long getId() {
return id;
}
public Person setId(long id) {
this.id = id;
return this;
}
public String getName() {
return name;
}
public Person setName(String name) {
this.name = name;
return this;
}
public RealmList<Dog> getRealmList() {
return mRealmList;
}
public Person setRealmList(ArrayList<Dog> dogList) {
mRealmList = new RealmList<>();
mRealmList.addAll(dogList);
return this;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeLong(this.id);
dest.writeString(this.name);
dest.writeTypedList(this.mRealmList);
}
protected Person(Parcel in) {
this.id = in.readLong();
this.name = in.readString();
this.mRealmList = new RealmList<>();
this.mRealmList.addAll(in.createTypedArrayList(Dog.CREATOR));
}
public static final Parcelable.Creator<Person> CREATOR = new Parcelable.Creator<Person>() {
@Override
public Person createFromParcel(Parcel source) {
return new Person(source);
}
@Override
public Person[] newArray(int size) {
return new Person[size];
}
};
}
Dog.java:
package com.entity;
import android.os.Parcel;
import android.os.Parcelable;
import io.realm.RealmObject;
import io.realm.annotations.PrimaryKey;
/**
* Dog
* Created by Maher Abuthraa on 6/9/17.
*/
public class Dog extends RealmObject implements Parcelable {
@PrimaryKey
private long id;
private String name;
private int age;
public Dog() {
}
public Dog(long id, String name, int age) {
this.id = id;
this.name = name;
this.age = age;
}
public long getId() {
return id;
}
public Dog setId(long id) {
this.id = id;
return this;
}
public String getName() {
return name;
}
public Dog setName(String name) {
this.name = name;
return this;
}
public int getAge() {
return age;
}
public Dog setAge(int age) {
this.age = age;
return this;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeLong(this.id);
dest.writeString(this.name);
dest.writeInt(this.age);
}
protected Dog(Parcel in) {
this.id = in.readLong();
this.name = in.readString();
this.age = in.readInt();
}
public static final Parcelable.Creator<Dog> CREATOR = new Parcelable.Creator<Dog>() {
@Override
public Dog createFromParcel(Parcel source) {
return new Dog(source);
}
@Override
public Dog[] newArray(int size) {
return new Dog[size];
}
};
}
I hope that may help,'.
