My styles.xml (v21): (same as older except here its parent is Material, before it was Holo) <style name="Theme.FullScreen" parent="@android:style/Theme.Material.Light.NoActionBar.Fullscreen"> <item name="android

问题 I'm currently able to obtain a file URI by opening the Lollipop file picker using the code below: Intent intent = new Intent(); intent.setAction(Intent.ACTION_OPEN_DOCUMENT_TREE); startActivity(intent); The file picker opens either at the root of Internal Storage or the last directory that I opened.

问题 This question is short. How do I set a background for buttons and such, that will have the native look&feel of Lollipop (ripple etc...) for Lollipop and above, and Kitkat style for Kitkat and below?
