<p>The system widgets have a new design and touch feedback animations. You can customize the
|
|
color palette, the touch feedback animations, and the activity transitions for your app.</p>
|
|
|
|
<p>The material theme is defined as:</p>
|
|
|
|
<ul>
|
|
<li><code>@android:style/Theme.Material</code> (dark version)</li>
|
|
<li><code>@android:style/Theme.Material.Light</code> (light version)</li>
|
|
<li><code>@android:style/Theme.Material.Light.DarkActionBar</code></li>
|
|
</ul>
|
|
|
|
<p>For a list of material styles that you can use, see the API reference for
|
|
<code>android.R.style</code>.</p>
|
|
|
|
<p class="note">
|
|
<strong>Note:</strong> The material theme is only available in the Android L Developer Preview.

<h2 id="colorpalette">Customize the Color Palette</h2>
|
|
|
|
<p style="margin-bottom:30px">To customize the theme's base colors to fit your brand, define
|
|
your custom colors using theme attributes when you inherit from the material theme:</p>
|
|
|
|
<pre>
|
|
<resources>
|
|
<!-- inherit from the material theme -->
|
|
<style name="AppTheme" parent="android:Theme.Material">
|
|
<!-- Main theme colors -->
|
|
<!-- your app's branding color (for the app bar) -->
|
|
<item name="android:colorPrimary">@color/primary</item>
|
|
<!-- darker variant of colorPrimary (for status bar, contextual app bars) -->
|
|
<item name="android:colorPrimaryDark">@color/primary_dark</item>
|
|
<!-- theme UI controls like checkboxes and text fields -->
|
|
<item name="android:colorAccent">@color/accent</item>
|
|
</style>
|
|
</resources>
|
|
</pre>
|
|
|
|
|
|
<h2 id="statusbar">Customize the Status and Navigation Bar</h2>
|
|
|
|
<p>The material theme lets you easily customize the status bar, so you can specify a
|
|
color that fits your brand and provides enough contrast to show the white status icons. To
|
|
set a custom color for the status bar, use the <code>android:statusBarColor</code> attribute when
|
|
you extend the material theme. By default, <code>android:statusBarColor</code> inherits the
|
|
value of <code>android:colorPrimaryDark</code>.</p>
|
|
|
|
<p>To handle the color of the status bar yourself (for example, by adding a gradient in the
|
|
background), set the <code>android:statusBarColor</code> attribute to
|
|
<code>@android:color/transparent</code> and adjust the window flags as required. You can
|
|
also use the <code>Window.setStatusBarColor</code> method for animations or fading.</p>
|
|
|
|
<p class="note"><strong>Note:</strong>
|
|
The status bar should almost always have a clear delineation from the primary toolbar, except for
|
|
full-bleed imagery cases and when you use a gradient as a protection.
|
|
</p>
|
|
|
|
<p>When customizing the navigation and status bars, make them both transparent or modify only
|
|
the status bar. The navigation bar should remain black in all other cases.</p>
|
|
|
|
|
|
<h2 id="inheritance">Theme Individual Views</h3>
|
|
|
|
<p>Elements in XML layout definitions can specify the <code>android:theme</code> attribute,
|
|
which references a theme resource. This attribute modifies the theme for the element and any
|
|
elements inflated below it, which is useful to alter theme color palettes in a specific portion
|
|
of an interface.</p> |
