    <p>When you are creating an object of intent, you can take advantage of following two methods for passing objects between two activities.</p> <p><a href="http://developer.android.com/reference/android/os/Bundle.html#putParcelable%28java.lang.String,%20android.os.Parcelable%29" rel="nofollow noreferrer">putParceble</a></p> <p><a href="http://developer.android.com/reference/android/os/Bundle.html#putSerializable%28java.lang.String,%20java.io.Serializable%29" rel="nofollow noreferrer">putSerializable</a></p> <p>What you can do with this, is have your class implement either <a href="http://developer.android.com/reference/android/os/Parcelable.html" rel="nofollow noreferrer">Parcelable</a> or <a href="http://developer.android.com/reference/java/io/Serializable.html" rel="nofollow noreferrer">Serializable</a>.</p> <p>Then you can pass around your custom classes across activities. I have found this very useful.</p> <p>Here is a small snippet of code I am using</p> <pre><code>Matrix matrix = new Matrix (); Intent i = new Intent(); Bundle b = new Bundle(); b.putParcelable("CUSTOM_LISTING", matrix ); i.putExtras(b); i.setClass(this, NextActivity.class); startActivity(i); </code></pre> <p>And in newly started activity code will be something like this...</p> <pre><code>Bundle b = this.getIntent().getExtras(); if(b!=null) mCurrentListing = b.getParcelable("CUSTOM_LISTING"); </code></pre> <p>** EDITED WITH LINKS::: **</p> <p><a href="http://groups.google.com/group/android-beginners/browse_thread/thread/676a603928950e24/a898ae5c217318e1" rel="nofollow noreferrer">LINK1</a> consist of sample code</p> <p><a href="https://stackoverflow.com/questions/2736389/how-to-pass-object-from-one-activity-to-another-in-android">LINK2</a></p> <p><a href="http://shri.blog.kraya.co.uk/2010/04/26/android-parcel-data-to-pass-between-activities-using-parcelable-classes/" rel="nofollow noreferrer">LINK3</a></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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
