I'm confused on button styles for material design. I'd like to get colorful raised buttons like in the attached link., like the "force stop" and "uninstall" buttons seen under the usage section. Are there available styles or do I need to define them?
http://www.google.com/design/spec/components/buttons.html#buttons-usage
I couldn't find the default button styles.
Example:
<Button style="@style/PrimaryButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Calculate"
android:id="@+id/button3"
android:layout_below="@+id/editText5"
android:layout_alignEnd="@+id/editText5"
android:enabled="true" />
If I try to change the background color of the button by adding
android:background="@color/primary"
all of the styles go away, such as the touch animation, shadow, rounded corner, etc.

I've just created an android library, that allows you to easily modify the button color and the ripple color
https://github.com/xgc1986/RippleButton
<com.xgc1986.ripplebutton.widget.RippleButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/btn"
android:text="Android button modified in layout"
android:textColor="@android:color/white"
app:buttonColor="@android:color/black"
app:rippleColor="@android:color/white"/>
You don't need to create an style for every button you want wit a different color, allowing you to customize the colors randomly
you can give aviation to the view by adding z axis to it and can have default shadow to it. this feature was provided in L preview and will be available after it release. For now you can simply add a image the gives this look for button background
Beside android.support.design.button.MaterialButton
(which mentioned by Gabriele Mariotti),
There is also another Button
widget called com.google.android.material.button.MaterialButton
which has different styles and extends from AppCompatButton
:
style="@style/Widget.MaterialComponents.Button"
style="@style/Widget.MaterialComponents.Button.UnelevatedButton"
style="@style/Widget.MaterialComponents.Button.TextButton"
style="@style/Widget.MaterialComponents.Button.Icon"
style="@style/Widget.MaterialComponents.Button.TextButton.Icon"
Filled, elevated Button
(default):
style="@style/Widget.MaterialComponents.Button"
style="@style/Widget.MaterialComponents.Button.UnelevatedButton"
style="@style/Widget.MaterialComponents.Button.TextButton"
style="@style/Widget.MaterialComponents.Button.Icon"
app:icon="@drawable/icon_24px" // Icons can be added from this
Read: https://material.io/develop/android/components/material-button/
A convenience class for creating a new Material button.
This class supplies updated Material styles for the button in the constructor. The widget will display the correct default Material styles without the use of the style flag.
I tried a lot of answer & third party libs, but none was keeping the border and raised effect on pre-lollipop while having the ripple effect on lollipop without drawback. Here is my final solution combining several answers (border/raised are not well rendered on gifs due to grayscale color depth) :
Lollipop
Pre-lollipop
build.gradle

android:textColor="@color/whatever_text_color_you_want"
app:backgroundTint="@color/whatever_background_color_you_want"/>
If I understand you correctly, you want to do something like this:
In such case, it should be just enough to use:
<item name="android:colorButtonNormal">#2196f3</item>
Or for API less than 21:
<item name="colorButtonNormal">#2196f3</item>
In addition to Using Material Theme Tutorial.
Animated variant is here.
With the stable release of Android Material Components in Nov 2018, Google has moved the material components from namespace
android.support.design
tocom.google.android.material
.
Material Component library is replacement for Android’s Design Support Library.
Add the dependency to your build.gradle
:
dependencies { implementation ‘com.google.android.material:material:1.0.0’ }
Then add the MaterialButton
to your layout:
<com.google.android.material.button.MaterialButton
style="@style/Widget.MaterialComponents.Button.OutlinedButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
app:strokeColor="@color/colorAccent"
app:strokeWidth="6dp"
app:layout_constraintStart_toStartOf="parent"
app:shapeAppearance="@style/MyShapeAppearance"
/>
You can check the full documentation here and API here.
To change the background color you have 2 options.
backgroundTint
attribute.Something like:
<style name="MyButtonStyle"
parent="Widget.MaterialComponents.Button">
<item name="backgroundTint">@color/button_selector</item>
//..
</style>
materialThemeOverlay
attribute.Something like:
<style name="MyButtonStyle"
parent="Widget.MaterialComponents.Button">
<item name=“materialThemeOverlay”>@style/GreenButtonThemeOverlay</item>
</style>
<style name="GreenButtonThemeOverlay">
<!-- For filled buttons, your theme's colorPrimary provides the default background color of the component -->
<item name="colorPrimary">@color/green</item>
</style>
The option#2 requires the 'com.google.android.material:material:1.1.0'.
OLD Support Library:
With the new Support Library 28.0.0, the Design Library now contains the MaterialButton
.
You can add this button to our layout file with:
<android.support.design.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="YOUR TEXT"
android:textSize="18sp"
app:icon="@drawable/ic_android_white_24dp" />
By default this class will use the accent colour of your theme for the buttons filled background colour along with white for the buttons text colour.
You can customize the button with these attributes:
app:rippleColor
: The colour to be used for the button ripple effectapp:backgroundTint
: Used to apply a tint to the background of the button. If you wish to change the background color of the button, use this attribute instead of background.
app:strokeColor
: The color to be used for the button stroke
app:strokeWidth
: The width to be used for the button strokeapp:cornerRadius
: Used to define the radius used for the corners of the buttonHere is how I got what I wanted.
First, made a button (in styles.xml
):
<style name="Button">
<item name="android:textColor">@color/white</item>
<item name="android:padding">0dp</item>
<item name="android:minWidth">88dp</item>
<item name="android:minHeight">36dp</item>
<item name="android:layout_margin">3dp</item>
<item name="android:elevation">1dp</item>
<item name="android:translationZ">1dp</item>
<item name="android:background">@drawable/primary_round</item>
</style>
The ripple and background for the button, as a drawable primary_round.xml
:
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="@color/primary_600">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="1dp" />
<solid android:color="@color/primary" />
</shape>
</item>
</ripple>
This added the ripple effect I was looking for.
Here is a sample that will help in applying button style consistently across your app.
Here is a sample Theme I used with the specific styles..
<style name="MyTheme" parent="@style/Theme.AppCompat.Light">
<item name="colorPrimary">@color/primary</item>
<item name="colorPrimaryDark">@color/primary_dark</item>
<item name="colorAccent">@color/accent</item>
<item name="android:buttonStyle">@style/ButtonAppTheme</item>
</style>
<style name="ButtonAppTheme" parent="android:Widget.Material.Button">
<item name="android:background">@drawable/material_button</item>
</style>
This is how I defined the button shape & effects inside res/drawable-v21 folder...
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?attr/colorControlHighlight">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="2dp" />
<solid android:color="@color/primary" />
</shape>
</item>
</ripple>
2dp corners are to keep it consistent with Material theme.
1) You can create rounded corner button by defining xml drawable and you can increase or decrease radius to increase or decrease roundness of button corner. Set this xml drawable as background of button.
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="4dp"
android:insetTop="6dp"
android:insetRight="4dp"
android:insetBottom="6dp">
<ripple android:color="?attr/colorControlHighlight">
<item>
<shape android:shape="rectangle"
android:tint="#0091ea">
<corners android:radius="10dp" />
<solid android:color="#1a237e" />
<padding android:bottom="6dp" />
</shape>
</item>
</ripple>
</inset>
2) To change default shadow and shadow transition animation between button states, you need to define selector and apply it to button using android:stateListAnimator property. For complete button customization reference : http://www.zoftino.com/android-button
