Android : change button text and background color

How can I change both text and background colors when my button is pressed, with xml ?

To change text color I can do :

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:color="mycolor"/>
    <item android:color="mycolor2"/>
</selector>

To change the background I can do (using it in a selector/item with drawable reference) :

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FF0079FF" />
</shape>

But how can I do both ? Let's say I want to have :

• Default : black text / white background
• Pressed : white text / blue background

EDIT : answer

I totaly forgot that the background and text color are managed separately, so this is how I did it :

<Button
    android:textColor="@color/filtersbuttoncolors"
    android:background="@drawable/mybackgroundcolors" />

In mybackgroundcolors.xml I manage the background and in filtersbuttoncolors.xml I manage the text color. In both xml files I manage the status (pressed, selected, default)

Since API level 21 you can use :

android:backgroundTint="@android:color/white"

you only have to add this in your xml

Here is an example of a drawable that will be white by default, black when pressed:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape>
            <solid
                android:color="#1E669B"/>
            <stroke
                android:width="2dp"
                android:color="#1B5E91"/>
            <corners
                android:radius="6dp"/>
            <padding
                android:bottom="10dp"
                android:left="10dp"
                android:right="10dp"
                android:top="10dp"/>
        </shape>

    </item>
    <item>
        <shape>
            <gradient
                android:angle="270"
                android:endColor="#1E669B"
                android:startColor="#1E669B"/>
            <stroke
                android:width="4dp"
                android:color="#1B5E91"/>
            <corners
                android:radius="7dp"/>
            <padding
                android:bottom="10dp"
                android:left="10dp"
                android:right="10dp"
                android:top="10dp"/>
        </shape>
    </item>
</selector>

I think doing this way is much simpler:

button.setBackgroundColor(Color.BLACK);

And you need to import android.graphics.Color; not: import android.R.color;

Or you can just write the 4-byte hex code (not 3-byte) 0xFF000000 where the first byte is setting the alpha.

Just complementing @Jonsmoke's answer.

For API level 21 and above you can use :

android:backgroundTint="@android:color/white"

in XML for the button layout.

For API level below 21 use an AppCompatButton using app namespace instead of android for backgroundTint.

For example:

<android.support.v7.widget.AppCompatButton
    android:id="@+id/my_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="My Button"
    app:backgroundTint="@android:color/white" />

add below line in styles.xml

<style name="AppTheme.Gray" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorButtonNormal">@color/colorGray</item>
    </style>

in button, add android:theme="@style/AppTheme.Gray", example:

<Button
            android:theme="@style/AppTheme.Gray"
            android:textColor="@color/colorWhite"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@android:string/cancel"/>

When you create an App, a file called styles.xml will be created in your res/values folder. If you change the styles, you can change the background, text color, etc for all your layouts. That way you don’t have to go into each individual layout and change the it manually.

styles.xml:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.AppBaseTheme" parent="@android:style/Theme.Light">
	<item name="android:editTextColor">#295055</item> 
    <item name="android:textColorPrimary">#295055</item>
    <item name="android:textColorSecondary">#295055</item>
    <item name="android:textColorTertiary">#295055</item>
    <item name="android:textColorPrimaryInverse">#295055</item>
    <item name="android:textColorSecondaryInverse">#295055</item>
    <item name="android:textColorTertiaryInverse">#295055</item>

     <item name="android:windowBackground">@drawable/custom_background</item>        
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

parent="@android:style/Theme.Light" is Google’s native colors. Here is a reference of what the native styles are: https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/themes.xml

name="Theme.AppBaseTheme" means that you are creating a style that inherits all the styles from parent="@android:style/Theme.Light". This part you can ignore unless you want to inherit from AppBaseTheme again. = <style name="AppTheme" parent="AppBaseTheme">

@drawable/custom_background is a custom image I put in the drawable’s folder. It is a 300x300 png image.

#295055 is a dark blue color.

My code changes the background and text color. For Button text, please look through Google’s native stlyes (the link I gave u above).

Then in Android Manifest, remember to include the code:

<application
android:theme="@style/Theme.AppBaseTheme">

Just use a MaterialButton and the app:backgroundTint and android:textColor attributes:

<MaterialButton
  app:backgroundTint="@color/my_color"
  android:textColor="@android:color/white"/>
