Android, setting background color of button loses ripple effect

You can add the ripple effect & background color with an additionnal ripple drawable:

your layout :

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent">    <Button        android:id="@+id/button_connect"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_marginTop="20dip"        android:fontFamily="sans-serif"        android:text="Connect"        android:background="@drawable/ripple"        android:textColor="#FFFFFF"        android:textSize="18sp" /></LinearLayout>

ripple.xml (this is where you can add background color in addition to the ripple effect) :

<?xml version="1.0" encoding="utf-8"?><!-- in drawable folder--><ripple    xmlns:android="http://schemas.android.com/apk/res/android"    android:color="?android:colorControlHighlight">    <item android:id="@android:id/mask">        <shape android:shape="rectangle">            <solid android:color="?android:colorAccent" />        </shape>    </item>    <item>        <shape android:shape="rectangle">            <!-- put your background color here-->            <solid android:color="@color/default_color" />        </shape>    </item></ripple>

A very simple and straight forward way of doing this is to set ?attr/selectableItemBackground to android:foreground attribute of your button. Following xml is perfectly valid and works

<Button    android:id="@+id/btn"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:background="@android:color/white"    android:foreground="?attr/selectableItemBackground"/>

Don't change the background of Button. Change the theme.

<style name="ButtonGray">    <item name="colorButtonNormal">@color/gray</item></style>

and in your xml file

<Button     android:id="@+id/accept_button"     android:layout_height="wrap_content"     android:layout_width="0dp"     android:layout_weight="1"     android:text="@string/button_accept_group"     android:theme="@style/ButtonGray"/>

Or you can add it in your main app theme

<style name="AppTheme"           parent="Theme.AppCompat.Light.NoActionBar">        <item name="colorButtonNormal">@color/primary_color</item></style>

And don't need change button background.

If you want totally custom background you need create your selector. And you can set there ripple effect.
