Android material design buttons - Pre lollipop

Question

How do I implement the "raised button" and the "flat button" as described in google's material design guidelines?

---

Raised buttons add dimension to mostly flat layouts. They emphasize > functions on busy or wide spaces.

---

Use flat buttons for toolbars and dialogs to avoid excessive layering.

You can use MaterialDesignLibrary. It's third party library.

You may also need to add a bottom margin to your button, in order to be able to see the raised-button shadow effect:

<item name="android:layout_marginBottom">@dimen/activity_vertical_margin</item>
<item name="android:elevation">1dp</item>
