Skip custom object between actions

Question

Skip custom object between actions

I tried many different solutions found here and on many other sites, but I just can't get it to work!

I have an “Apartment” object in one action that should be used in another action. The action starts from the MyMapOverlayItem class and must start with ApartmentInfoActivity, in which the Apartment object should be used.

MyMapOverlayItem.java:

package com.android.madsoft.spotter;

import java.util.ArrayList;

import android.content.Context;
import android.content.Intent;
import android.graphics.drawable.Drawable;
import android.os.Bundle;

import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;

public class MyMapOverlayIcon extends ItemizedOverlay<OverlayItem> {
    Context mContext;
    ArrayList<Apartment> myList;
    private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
    public MyMapOverlayIcon(Drawable defaultMarker) {
        super(defaultMarker);

    }

    public MyMapOverlayIcon(Drawable defaultMarker, Context context, ArrayList<Apartment> myList) {
        super(boundCenterBottom(defaultMarker));
          mContext = context;
          this.myList = myList;

        }

    public void addOverlay(OverlayItem overlay) {
        mOverlays.add(overlay);
        populate();
    }

    @Override
    protected boolean onTap(int index) {
        Apartment ap = myList.get(index);
        ApartmentParcel ap1 = new ApartmentParcel(ap);
        Intent i = new Intent(mContext, ApartmentInfoActivity.class);
        Bundle b = new Bundle();
        b.putParcelable("app", ap1);
        i.putExtras(b);
//      i.putExtra("app",ap1);
//      b.putSerializable("apartment", ap);

        // WHAT TO DO!?

        mContext.startActivity(i);

      return true;
    }

    @Override
    protected OverlayItem createItem(int i) {
      return mOverlays.get(i);
    }

    @Override
    public int size() {
      return mOverlays.size();
    }

}

Introduce the Aparment class class Serializable:

public class Apartment implements Serializable{

Then to MyMapOverlayIcon:

Bundle b = new Bundle();
// WHAT TO DO!?
b.putSerializable("apartment", ap);

Then to ApartmentInfoActivity:

Apartment ap = (Apartment) getIntent().getSerializableExtra("apartment");

:

Intent newActivity = ...;

// use your key here to put the parcelable into the bundle

newActivity.putExtras(extras);
startActivity(newActivity);

//child activity (onCreate())
Bundle intentExtras = getIntent().getExtras();
if(intentExtras != null){
   // use the key here to get your parcelable from the bundle
}

public class ExampleParcelable implements android.os.Parcelable {
