Material Design implementation for Android 2.1 and newer. This is not the exact copy of the Lollipop's API and features. It's a custom implementation of the most useful things as shown in the design specification. The library also features some additional non-standard extensions, like rounded corners for layouts or a Divider view for easy divider creation.
- realtime, animated shadows
- the touch ripple
- an elevation system (changing z order changes view rendering order)
- rounded corners
- SVG rendering
- a floating action button view
- text appearances, sizes, colors and many more useful definitions
- roboto and roboto condensed fonts for buttons and text fields
- predefined animation styles and visibility change animations
- a saturation/brightness/alpha fade for ImageView
- Divider, StatusBar and NavigationBar drag&drop view
- dark and light themes in standard and AppCompat versions
- a radial transition animation
- circular progress indicators
- CardView with real shadows and rounded corners
- state animators
- debug mode showing draw and hit areas when in edit mode
- tab strip with animated underline
- fading edges
- checkboxes and radiobuttons
Add the following line to dependencies:
compile 'tk.zielony:carbon:0.7.0'
And these two lines to android/defaultConfig:
renderscriptTargetApi 20
renderscriptSupportModeEnabled true
In case of any problems with these check the sample app.
I have an old Galaxy S with Android 2.3, so I did that to support my own phone. It's also fun to push the limits. Android 2.1 should work, the code compiles, but I have never checked that.
Seems like it's pretty stable. I'm testing it heavily on different devices and on real projects. There are minor problems with SVG rendering and shadow generation. Also the themes aren't perfect yet. These are the issues I know about. If you have something else, please let me know.
No. Maybe one day.
Done!
Do you plan to offer your Material elements as separate modules? I would prefer not to include the whole project only to use ripples.
I thought about it, but it's not that easy, because almost everything is tightly integrated with other components. For example the ripple. Due to clipping issues in Android < 5.0 it's not possible to draw borderless backgrounds just by setting the background drawable. That's why I would have to export the ripple with all layouts only to make the borderless mode work.
If you wish, you can copy RippleDrawable.java to your project and integrate it with your code manually.
If it's possible and reasonable, sure! Just let me know.
You have to add these lines to your android build config:
renderscriptTargetApi 20
renderscriptSupportModeEnabled true
Carbon uses RenderScript for generating shadows. Gradle doesn't support renderscript very well, so it has to be done that way.
Debug mode is a special rendering mode used for UI/UX debugging. Some of material components have touch areas larger than the actual components. It means that a user can tap outside a view and still trigger an action. Using debug mode you can preview all touch and draw areas in the editor. Red rectangles show hit areas, green rectanges - draw areas. Debug mode is also useful for SVG views debugging. SVG views appear empty, because SVG rendering is not supported in the editor.
To enable the debug mode, add the following line to your theme:
<item name="carbon_debugMode">true</item>
Then go to the editor and pick that theme to be used by the editor. You can create two themes, with and without the debug info, so you can switch between them.
<style name="AppTheme" parent="carbon_Theme.Light">
<!-- Customize your theme here. -->
</style>
<style name="AppTheme.Debug">
<item name="carbon_debugMode">true</item>
</style>
