    <p>I think the best way to describe my question, is to describe what I am doing first.</p> <p>I have a simple activity with 3 listpick options (Buttons that launch a listview). Each ListPicker has 8 items in the ListView.</p> <p>Each Item in the Listview, let's call it a value of Name, has a corresponding Address and Phone.</p> <p>So here are the example of the constatns I am using</p> <pre><code>public final String GROUP_1_VENUE_1_NAME = "1name1"; public final String GROUP_1_VENUE_1_ADDRESS = "1address1"; public final String GROUP_1_VENUE_1_PHONE = "1phone1"; public final String GROUP_1_VENUE_2_NAME = "1name2"; public final String GROUP_1_VENUE_2_ADDRESS = "1address2"; public final String GROUP_1_VENUE_2_PHONE = "1phone2"; public final String GROUP_1_VENUE_3_NAME = "1name3"; public final String GROUP_1_VENUE_3_ADDRESS = "1address3"; public final String GROUP_1_VENUE_3_PHONE = "1phone3"; ..... public final String GROUP_2_VENUE_1_NAME = "2name1"; public final String GROUP_2_VENUE_1_ADDRESS = "2address1"; public final String GROUP_2_VENUE_1_PHONE = "2phone1"; public final String GROUP_2_VENUE_2_NAME = "2name2"; public final String GROUP_2_VENUE_2_ADDRESS = "2address2"; public final String GROUP_2_VENUE_2_PHONE = "2phone2"; .... public final String GROUP_3_VENUE_1_NAME = "3name1"; public final String GROUP_3_VENUE_1_ADDRESS = "3address1"; public final String GROUP_3_VENUE_1_PHONE = "3phone1"; public final String GROUP_3_VENUE_2_NAME = "3name2"; public final String GROUP_3_VENUE_2_ADDRESS = "3address2"; public final String GROUP_3_VENUE_2_PHONE = "3phone2"; ... </code></pre> <p>So an item gets picked from a listPicker, and now I want to evaluate the result</p> <p>I have 3 Strings that need to be set; name, address, and phone</p> <p>so right now I have something like this...</p> <pre><code>if (selection.equals(GROUP_1_VENUE_1_NAME) { name = GROUP_1_VENUE_1_NAME; address = GROUP_1_VENUE_1_ADDRESS; phone = GROUP_1_VENUE_1_PHONE; } else if (selection.equals(GROUP_1_VENUE_2_NAME) { name = GROUP_1_VENUE_2_NAME; address = GROUP_1_VENUE_2_ADDRESS; phone = GROUP_1_VENUE_2_PHONE; } else if ..... </code></pre> <p>and so on and so forth.</p> <p>So, here is my question. Is there any easier way to do this that allows me to evaluate if the selection equals one of the NAME CONSTANTS and if so, set the corresponding values?</p>

    1. COMy first thought is a hashmap containing the values to set. The key would be `selection`. Though, I'm not sure the code would be as readable.

    3. COI think, it should be a typo here, `phone = GROUP_1_VENUE_1_NAME;`, it should be `phone = GROUP_1_VENUE_1_PHONE;`

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.
