Body
There's actually a fairly straight-forward way to do this, and to do it in a way that doesn't depend on a particular <code>enum</code>. I ran into this problem when wanting to use <code>enum</code>s to populate different parts of the UI. Here is a little bit of sample code to show you how I did it: <pre><code>public int enumPosition(Enum<?> lookingFor, Enum<?>[] lookingIn) { for (int i = 0; i < lookingIn.length; i++) { if (lookingIn[i].getValue().equals(lookingFor.getValue())) { //Found Answer } } } </code></pre> Of course, depending on what you need there are good ways to setup your <code>enum</code> to allow for better access and searching, here's what I mean: <pre><code>public enum ExampleEnum { firstValue("#1", 1), secondValue("#2", 2), thirdValue("#3", 3); private final String id; private final int somethingUseful; ExampleEnum(String id, int usefulValue) { this.id = id; this.somethingUseful = usefulValue; } public String getValue() { return id; } public int getSomethingUseful () { return somethingUseful; } public static ExampleEnumfromString(String text) { if (text != null) { for (ExampleEnumt : ExampleEnum.values()) { if (text.equalsIgnoreCase(t.id)) { return t; } } } //Usually best to throw an exception here return ExampleEnum.firstValue; } //Useful for passing to adapters public static String[] getValues() { String[] vals = new String[ExampleEnum.values().length]; int i = 0; for (ExampleEnumt : ExampleEnum.values()) { vals[i] = t.getValue(); i++; } return vals; } @Override public String toString() { return getValue(); } } </code></pre>

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.
