    <p>I am having trouble making my class <code>Parcelable</code>. The trouble is, I am trying to write to the parcel a member in the class which is an <code>ArrayList&lt;Parcelable&gt;</code> object. The <code>ArrayList</code> is <code>Serializable</code>, and the objects (<code>ZigBeeDev</code>) in the list are <code>Parcelable</code>. </p> <p>Here is the relevant code:</p> <pre><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; // the channel ArrayList&lt;Integer&gt; _lqis; // link quality indicators (to all devices?) ArrayList&lt;ZigBeeDev&gt; _devices; // the devices in the network public void writeToParcel(Parcel out, int flags) { out.writeString(_mac); out.writeString(_pan); out.writeInt(_band); out.writeSerializable(_lqis); out.writeParcelable(_devices, 0); // help here } private ZigBeeNetwork(Parcel in) { _mac = in.readString(); _pan = in.readString(); _band = in.readInt(); _lqis = (ArrayList&lt;Integer&gt;) in.readSerializable(); _devices = in.readParcelable(ZigBeeDev.class.getClassLoader()); // help here } public int describeContents() { return this.hashCode(); } public static final Parcelable.Creator&lt;ZigBeeNetwork&gt; CREATOR = new Parcelable.Creator&lt;ZigBeeNetwork&gt;() { public ZigBeeNetwork createFromParcel(Parcel in) { return new ZigBeeNetwork(in); } public ZigBeeNetwork[] newArray(int size) { return new ZigBeeNetwork[size]; } }; //... } </code></pre> <p>I have marked two spots "// help here" to understand how to properly write to the parcel and how to reconstruct it. If <code>ZigBeeDev</code> is <code>Parcelable</code> (properly tested), how do I do this properly?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
