    <p>I'd like to make class A Parcelable.</p> <pre><code>public class A { public String str; public ArrayList&lt;B&gt; list; } </code></pre> <p>This is what I've come up with so far. However it crashes with a NullPointerException. The problem are these two statements: <code>dest.writeList(list);</code> &amp; <code>in.readList(list, this.getClass().getClassLoader());</code>. I can't figure out what to do from here :(</p> <p><strong>Class A</strong></p> <pre><code>public class A implements Parcelable { public String str; public ArrayList&lt;B&gt; list; @Override public int describeContents() { // TODO Auto-generated method stub return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest.writeString(str); dest.writeList(list); } private A(Parcel in) { str = in.readString(); in.readList(list, this.getClass().getClassLoader()); } public static final Parcelable.Creator&lt;A&gt; CREATOR = new Parcelable.Creator&lt;A&gt;() { public A createFromParcel(Parcel in) { return new A(in); } public A[] newArray(int size) { return new A[size]; } }; } </code></pre> <p><strong>Class B</strong></p> <pre><code>public class B implements Parcelable { public String str; @Override public int describeContents() { // TODO Auto-generated method stub return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest.writeString(str); } private B(Parcel in) { str = in.readString(); } public static final Parcelable.Creator&lt;B&gt; CREATOR = new Parcelable.Creator&lt;B&gt;() { public B createFromParcel(Parcel in) { return new B(in); } public B[] newArray(int size) { return new B[size]; } }; } </code></pre> <p>Thank you for your time.</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.
