Lollipop: Disabled button –> which style?

I tried to track down, how Lollipop displays a button, which is disabled with android:enabled="false" in the layout file.


With Holo, it’s easy: In the styles_holo.xml, I find the style Widget.Holo.Button, which gives me a reference to @drawable/btn_default_holo_dark. There I find the selector:

  • Select multiple images from android gallery
  • OpenGL ES 2.0 vs OpenGL 3 - Similarities and Differences
  • Precise metronome for android
  • File Chooser not works in Samsung Tab 3 Android 4.4
  • Delete system cache on android 6.0
  • android app that accesses the sim toolkit
  • <selector xmlns:android="">
    <item android:state_window_focused="false" android:state_enabled="true"
    android:drawable="@drawable/btn_default_normal_holo_dark" />
    <item android:state_window_focused="false" android:state_enabled="false"
    android:drawable="@drawable/btn_default_disabled_holo_dark" />
    <item android:state_pressed="true"
    android:drawable="@drawable/btn_default_pressed_holo_dark" />
    <item android:state_focused="true" android:state_enabled="true"
    android:drawable="@drawable/btn_default_focused_holo_dark" />
    <item android:state_enabled="true"
    android:drawable="@drawable/btn_default_normal_holo_dark" />
    <item android:state_focused="true"
    android:drawable="@drawable/btn_default_disabled_focused_holo_dark" />
    android:drawable="@drawable/btn_default_disabled_holo_dark" />


    When I try to apply the same logic to Lollipop, I got stuck:

    In styles_material.xml I find the style <style name="Widget.Material.Button"> where I find the reference to <item name="background">@drawable/btn_default_material</item>. But there is no selector??!! Instead I find:

    <ripple xmlns:android=""
    <item android:drawable="@drawable/btn_default_mtrl_shape" />

    Could someone please explain, which specific style Lollipop uses for a disabled button.
    Thanks a lot!


    I can partially answer myself: In @drawable/btn_default_mtrl_shape I find a reference to <solid android:color="?attr/colorButtonNormal" />, which in turn points to @color/btn_default_material_light, which includes a selector:

    <selector xmlns:android="">
    <item android:state_enabled="false"
    <item android:color="@color/button_material_light"/>

    But that alpha value only explains half of it. Somehow Lollipop also set the elevation down to 0?

    This is how I resolved this, thanks to your partially answer.

    First: add new Folder “color” under “res” folder, if it doesn`t exist.enter image description here

    Add new .xml file in “color” folder (I will call this file ButtonColorSelector.xml) where we will create new ColorStateList like this:

    <?xml version="1.0" encoding="UTF-8" ?>
    <selector xmlns:android="">
        <item android:state_enabled="false" android:color="#F2F2F2"/> <!-- disabled -->
        <item android:state_pressed="true" android:color="#FF0000"/> <!-- pressed -->
        <item android:state_focused="true" android:color="#FF0000"/> <!-- focused -->
        <item android:color="#0000FF"/> <!-- default -->

    Second: Add that ripple effect .xml file you mentioned, under “drawable” folder and reference your colorSelector instead of btn_default_mtrl_shape. I will call this file RaisedButton.xml.

    <?xml version="1.0" encoding="utf-8"?>
    <ripple xmlns:android=""
                <solid android:color="@color/buttoncolorselector"/>
                <corners android:radius="5dp" />

    Third: Now you can use your drawable for button background in your layouts, like this:

        android:id="@+id/someButton" />
