    <p>I'm trying to make a custom dialog for my android application. I get null pointer exceptions when I attempt to access the fields from the 'ok' button method. It seems like my fields fade from existence as soon as the onclick listener fires. Is there a better way to do this?</p> <pre><code>addchars.xml &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/scrollBox"&gt;

    1. COI would combine a few of those if statements, it would be easier to follow...

    2. CO@Pearsonartphoto I was a bit concerned with which fields weren't completed in an earlier draft of this. I'll try to clean it up, thanks.

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).
