    <p>Since I am new to Android, I am now thinking on what is the correct way of doing things.</p> <p>As it stands, the application Im writing has 4 different screens:</p> <ul> <li>Screen 1 - list of nodes (main screen)</li> <li>Screen 2 - options menu, tableLayout with buttons</li> <li>Screen 3 - navigation</li> <li>Screen 4 - text details on version etc</li> </ul> <p>These screens can be navigated to/from using a "header" View that is placed on top. The header then has 4 different buttons:</p> <pre><code>+--------------------+ | menu with buttons | +--------------------+ | | | | | | | C O N T E N T | | | | | | | +--------------------+ </code></pre> <p><b>main.xml</b> is really just a LinearLayout that INCLUDES the header.xml and then the content, in that case the list of nodes in a ListView</p> <p><b>options.xml</b> is the same thing almost, it includes the headerxml and then a bunch of buttons...</p> <p>...and so on with the two other screens.</p> <p>So, when I press one of the buttons in the header/menu on top the content should be switched to that screen. <b>My question is:</b></p> <ul> <li><p>Should I create one Activity for each screen? I read on Google that:<br> <i>An activity presents a visual user interface for one focused endeavor the user can undertake.</i><br> So that can be interpretet that I shoukd use one Activity for each of these screens.</p></li> <li><p>Should I <b>not</b> create more Activities than the startup, and then just run the <i>setContentView(R.layout.whatever)</i> when I want to change the "content" above?</p></li> </ul> <p>Regards</p>

    1. COAs a follow-up question to that: the header, as defined in header.xml, has 4 buttons. Where do I attach the click listeners for those? I do not have a specific Activity for the header.xml. Should I have that? Or should I attach listeners in my Main.java Activity?

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.
