How to pass List through Intents

Question

I have ArrayList Of Custom Objects

ArrayList<AvailableCountry>
        listAvailableCountries = new ArrayList();

and I have two objects of AvailableCountry

AvailableCountry obj1=new AvailableCountry();
AvailableCountry obj2=new AvailableCountry();

Then i have added to arraylist

listAvailableCountries.add(obj1);
listAvailableCountries.add(obj2);

And this is Class of Custom Object

public class AvailableCountry {

@SerializedName("Disabled")
@Expose
private Boolean disabled;
@SerializedName("Selected")
@Expose
private Boolean selected;
@SerializedName("Text")
@Expose
private String text;
@SerializedName("Value")
@Expose
private String value;

public Boolean getDisabled() {
    return disabled;
}

public void setDisabled(Boolean disabled) {
    this.disabled = disabled;
}

public Boolean getSelected() {
    return selected;
}

public void setSelected(Boolean selected) {
    this.selected = selected;
}

public String getText() {
    return text;
}

public void setText(String text) {
    this.text = text;
}

public String getValue() {
    return value;
}

public void setValue(String value) {
    this.value = value;
}

}

Now i want to pass this arraylist From Activity A to Activity B. and then i want to receive in Activity B. how can i achieve this task.

By letting `AvailableCountry` implement `Parcelable` – 0xDEADC0DE Feb 02 '17 at 09:56 — 0xDEADC0DE, Feb 02 '17 at 09:56

1) First of all implement Serializable interface to your Custom Object Class

public class AvailableCountry implements Serializable {

@SerializedName("Disabled")
@Expose
private Boolean disabled;
@SerializedName("Selected")
@Expose
private Boolean selected;
@SerializedName("Text")
@Expose
private String text;
@SerializedName("Value")
@Expose
private String value;

public Boolean getDisabled() {
    return disabled;
}

public void setDisabled(Boolean disabled) {
    this.disabled = disabled;
}

public Boolean getSelected() {
    return selected;
}

public void setSelected(Boolean selected) {
    this.selected = selected;
}

public String getText() {
    return text;
}

public void setText(String text) {
    this.text = text;
}

public String getValue() {
    return value;
}

public void setValue(String value) {
    this.value = value;
}

}

2) Send the arrayList from your Class A to Class B

Intent intent =new Intent(A.this,B.class);
intent.putExtra("listCountry", (Serializable) listAvailableCountries);
startActivity(intent)

3) Receive the arraylist in Class B

ArrayList<AvailableCountry>listAvailableCountries = (ArrayList<AvailableCountry>) getIntent().getSerializableExtra("listCountry");

using Gson we can easily share the data

compile 'com.google.code.gson:gson:2.4'

send like this in A.class

 Intent intent = new Intent(A.this, B.class);
    String favJSONString = new Gson().toJson(listAvailableCountries);
    intent.putExtra("listAvailableCountries", favJSONString);
    startActivity(intent);

and receive like this B.class

try {
        Type type = new TypeToken<List<AvailableCountry>>() {
        }.getType();
        ArrayList<AvailableCountry> listAvailableCountries  = new Gson().fromJson(getIntent().getStringExtra("listAvailableCountries"), type);
    } catch (Exception e) {
        e.printStackTrace();
    }
