问题

From examples provided on the Android Developer pages I see that new Views, like the RecyclerView, are backward compatible (android.support.v7.widget.RecyclerView).

Are all the new things introduced in Material Design backward compatible (to which version)?

回答1:

Updating this answer as Lollipop OS is officially released with support libraries, which you can use inside your project to provide compatibility to older versions.

Support library: v7 appcompat library

This library adds support for the Action Bar user interface design pattern. This library includes support for material design user interface implementations.

If you are using Android Studio then you just need to include below dependency identifier:

com.android.support:appcompat-v7:21.0.+

Material Design from Android 2.2 (API 8) to present 5.0 (API 21)

Here is what you need:

Toolbar
Material Design Library for widgets (buttons, checkboxes, etc)

1. Toolbar

Just get the idea and you ready to go.

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimaryDark"/>

Source with example: https://github.com/antoniolg/MaterialEverywhere

To make Toolbar work lower API 11 use Theme.AppCompat.Light.NoActionBar (instead windowActionBar set to false)

<style name="NoActionBarTheme" parent="Theme.AppCompat.Light.NoActionBar">
     ...
</style>

2. Material Design Library

Here is Material Design Library for pretty buttons, etc..

回答3:

Officialy the Material Design is backwards to the v7 appcompat Support Library.

回答4:

Just to add on to Paresh's answer, not all the features of Material Design are available on older releases. Custom themes and activity transitions are only available for APIs > 21, however as others mentioned some of the features are available in support library.

回答5:

The API is included since version 22. You need include this dependency in to gradle dependency:

com.android.support:design:22.2.0

回答6:

Google design support library introduced in I/O 2015

http://android-developers.blogspot.gr/2015/05/android-design-support-library.html

You will find a lot of good stuff for material design there.

Navigation View
Snackbar
Floating Action Button
CoordinatorLayout, motion, and scrolling (the best part wich include parallax effect and pinned toolbars)

and much more ...
