Passing an ArrayList of Objects to the new Activity

Question

I have an ArrayList of objects. ie ArrayList<ObjectName>.

I want to pass this to a new Activity. I tried to use putParcelableArrayList but it has issues with the object. I removed the <ObjectName> part from the creating of the variable and the method works but then I get eclipse complaining about unsafe stuff.

How do I pass this ArrayList<ObjectName> to a new Activity

Thanks for your time

EDIT I tried this :

ArrayList<ObjectName> arraylist = new Arraylist<ObjectName>(); Bundle bundle = new Bundle(); bundle.putParcelableArrayList("arraylist", arraylist); 

I get the following Error:

The method `putParcelableArrayList(String, ArrayList<? extends Parcelable>)` in the type `Bundle` is not applicable for the arguments `(String, ArrayList<ObjectName>)` 

EDIT2 Object Example Code. Do I need to changed this for Parcelable to work?

public class ObjectName {     private int value1;     private int value2;     private int value3;      public ObjectName (int pValue1, int pValue2, int Value3) {         value1 = pValue1;         value2 = pValue2;         value3 = pValue3;     }      // Get Statements for each value below     public int getValue1() {         return value1;     }      // etc

Your object class should implement parcelable. The code below should get you started.

    public class ObjectName implements Parcelable {      // Your existing code          public ObjectName(Parcel in) {             super();              readFromParcel(in);         }          public static final Parcelable.Creator<ObjectName> CREATOR = new Parcelable.Creator<ObjectName>() {             public ObjectName createFromParcel(Parcel in) {                 return new ObjectName(in);             }              public ObjectName[] newArray(int size) {                  return new ObjectName[size];             }          };          public void readFromParcel(Parcel in) {           Value1 = in.readInt();           Value2 = in.readInt();           Value3 = in.readInt();          }         public int describeContents() {             return 0;         }          public void writeToParcel(Parcel dest, int flags) {             dest.writeInt(Value1);             dest.writeInt(Value2);               dest.writeInt(Value3);        }     } 

To use the above do this:

In 'sending' activity use:

ArrayList<ObjectName> arraylist = new Arraylist<ObjectName>();   Bundle bundle = new Bundle();   bundle.putParcelableArrayList("arraylist", arraylist); 

In 'receiving' activity use:

Bundle extras = getIntent().getExtras();   ArrayList<ObjectName> arraylist  = extras.getParcelableArrayList("arraylist");   ObjectName object1 = arrayList[0]; 

and so on.

Very Easy way, try the following:

bundle.putSerializable("lstContact", (Serializable) lstObject); lstObj = (List<Contacts>) bundle.getSerializable("lstContact"); 

and also you will need to implement your Contact class from Serializable interface. ex :

public class Contact implements Serializable{    ...    ...    ... }
