Use API for cart items based on user id best for you and get all added cart items — , Jul 24 '18 at 10:21
U will do it by making putExtra into intent look at this https://stackoverflow.com/questions/5265913/how-to-use-putextra-and-getextra-for-string-data — Kebab Krabby, Jul 24 '18 at 10:22
AddedPizzaInfo bookmarkerPojo = new AddedPizzaInfo(); bookmarkerPojo.SetName(c.getName()); bookmarker_array.add( bookmarkerPojo); Adding item by this way. — lavika, Jul 24 '18 at 10:46

Make your Item class implement @Parcel (using this library https://github.com/johncarl81/parceler)

then, on the first activity:

Intent startSecondActivityIntent = new Intent(this, SecondActivity.class);
startSecondActivityIntent.putExtra("items", Parcels.wrap(yourListOnItems));
startActivity(startSecondActivityIntent);

on the second acitivty:

@Override
protected void onCreate(Bundle savedInstanceState) {
    Bundle bundle = this.getIntent().getExtras();
    listOfItems = Parcels.unwrap(bundle.getParcelable("items"));
}

Alternatively to using Parceler library you could implement Parceleable natively but will take too much time and generate too much boilerplate code.

EDIT:

AddedPizzaInfo.class:

@Parcel
public class AddedPizzaInfo{
    //code whatever

    //add empty constructer, required by parceler
    public AddedPizzaInfo(){} 

    //rest of the code
}

build.gradle:

...

dependencies {

   ///other dependencies
    implementation 'org.parceler:parceler-api:1.1.9'
    annotationProcessor 'org.parceler:parceler:1.1.9'
}

and then run the code I first added when you want to send the objects you your second activity.

Unable to find generated Parcelable class for com.pizza_App.AddedPizzaInfo, verify that your class is configured properly and that the Parcelable .Getting this error. – lavika Jul 24 '18 at 11:59
Check here https://github.com/johncarl81/parceler an example of a class implementing Parcel. Check if your is the same – Tiago Ornelas Jul 24 '18 at 12:53

To send list data from one activity use the following code sample

Intent intent = new Intent(this, TargetActivity.class);
        intent.putStringArrayListExtra("your_list",listOfData);
        startActivity(intent);

To retrieve the list in TargetActivity use

if(getIntent()!=null){
    your_array_list = getIntent().getStringArrayListExtra("your_list");
}
