<p>When writing an app for Android, keep in mind that Android devices come in many different screen
|
|
sizes and types. Make sure that your app consistently provides a balanced and aesthetically pleasing
|
|
layout by adjusting its content to varying screen sizes and orientations.</p>
|
|
<p><em>Panels</em> are a great way for your app to achieve this. They allow you to combine multiple views into
|
|
one compound view when a lot of horizontal screen real estate is available and by splitting them up
|
|
when less space is available.</p>
|
|
<h2>Combining Multiple Views Into One</h2>
|
|
<p>On smaller devices your content is typically divided into a master grid or list view and a detail
|
|
view. Touching an item in the master view opens a different screen showing that item's detail
|
|
information.</p>
|
|
|
|
<img src="../static/content/multipane_views.png">
|
|
|
|
<p>Because tablets have more screen real estate than phones, you can use panels to combine the related
|
|
list and detail views into a single compound view. This uses the additional space more efficiently
|
|
and makes navigating the app easier. </p>
|
|
|
|
<img src="../static/content/multipane_view_tablet.png">
|
|
|
|
<p>In general, use the pane on the right to present more information about the item you selected in the
|
|
left pane. Make sure to keep the item in the left pane selected in order to establish the
|
|
relationship between the panels.</p>
|
|
<h2>Compound Views and Orientation Changes</h2>
|
|
<p>Screens should have the same functionality regardless of orientation. If you use a compound view in
|
|
one orientation, don't split it up when the user rotates the screen. There are several techniques
|
|
you can use to adjust the layout after orientation change while keeping functional parity intact.</p>

<h4>Stretch/compress</h4>
|

<p>Adjust the column width of your left pane to achieve a balanced layout in both orientations.</p>

|
|
|
|
<h4>Expand/collapse</h4>
|
|
<p>When the device rotates, collapse the left pane view to only show the most important information.
|
|
Provide an <em>expand</em> control that allows the user to bring the left pane content back to its original
|
|
width and vice versa.</p>

<div class="layout-content-col span-5">
|

<h4>Show/hide</h4>
|
|
<p>After rotating the device, show the right pane in fullscreen view. Use the Up icon in the action bar
|
|
to show the left panel and allow navigation to a different email. Hide the left panel by touching
|
|
the content in the detail panel.</p>

<h2>Checklist</h2>
|
|
<ul>
|
|
<li>
|
|
<p>Plan in advance on how your app scales to different screen sizes and screen orientations.</p>
|
|
</li>
|
|
<li>
|
|
<p>Identify the most appropriate method for the panels in your compound views to reorganize
|
|
themselves when screen orientation changes.</p>
|
|
</li>
|
|
<li>
|
|
<p>Look for opportunities to consolidate your views into multi-panel compound views.</p>
|
|
</li>
|
|
<li>
|
|
<p>Make sure that your screens provide functional parity after the screen orientation
|
|
changes.</p>
|
|
