parcelable

I need to pass a reference to the class that does the majority of my processing through a bundle. The problem is it has nothing to do with intents or contexts and has a large amount of non-primitive objects. How do I package the class into a parcelable/serializable and pass it to a startActivityForResult ? Figuring out what path to take requires answering not only CommonsWare's key question of "why" but also the question of "to what?" are you passing it. The reality is that the only thing that can go through bundles is plain data - everything else is based on interpretations of what that data

I've been reading a lot of posts and articles extolling the speed of Parcelable over Serializable. I've been using both for a while to pass data between Activities through Intents, and have yet to notice any speed difference when switching between the two. The typical amount of data I have to transfer is 5 to 15 nested objects with 2 to 5 fields each. Since I have about 30 classes which must be transferable, implementing Parcelable requires a lot of boilerplate code that adds maintenance time. One of my current requirements is also that the compiled code should be as small as possible; I

I am having trouble making my class Parcelable . The trouble is, I am trying to write to the parcel a member in the class which is an ArrayList<Parcelable> object. The ArrayList is Serializable , and the objects ( ZigBeeDev ) in the list are Parcelable . Here is the relevant code: package com.gnychis.coexisyst; import java.util.ArrayList; import java.util.Iterator; import android.os.Parcel; import android.os.Parcelable; public class ZigBeeNetwork implements Parcelable { public String _mac; // the source address (of the coordinator?) public String _pan; // the network address public int _band;

I have following class which reads and writes an array of objects from/to a parcel: class ClassABC extends Parcelable { MyClass[] mObjList; private void readFromParcel(Parcel in) { mObjList = (MyClass[]) in.readParcelableArray( com.myApp.MyClass.class.getClassLoader())); } public void writeToParcel(Parcel out, int arg1) { out.writeParcelableArray(mObjList, 0); } private ClassABC(Parcel in) { readFromParcel(in); } public int describeContents() { return 0; } public static final Parcelable.Creator<ClassABC> CREATOR = new Parcelable.Creator<ClassABC>() { public ClassABC createFromParcel(Parcel in)

Why bundle has getParcelableArrayList , getParcelable methods; but Intent has only putParcelableArrayListExtra method? Can I transmit only object<T> , not ArrayList of one element? Then, what is getParcelable for? yorkw Intent provides bunch of overloading putExtra() methods. Suppose you have a class Foo implements Parcelable properly, to put it into Intent in an Activity: Intent intent = new Intent(getBaseContext(), NextActivity.class); Foo foo = new Foo(); intent.putExtra("foo ", foo); startActivity(intent); To get it from intent in another activity: Foo foo = getIntent().getExtras()

I have an ArrayList with custom objects that I would like to be able to save and restore on a screen rotate. I know that this can be done with onSaveInstanceState and onRestoreInstanceState if I were to make the ArrayList its own class, which implements either Parcelable or Serializable ... But is there a way to do this without creating another class? You do not need to create a new class to pass an ArrayList of your custom objects. You should simply implement the Parcelable class for your object and use Bundle#putParcelableArrayList() in onSaveInstanceState() and onRestoreInstanceState() .
