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"/>
add below lines in the styles.xml
<style name="AppTheme.Gray" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorGray</item>
</style>
and 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"/>

I'm trying to define a custom color for my app's theme.
Here is how I do:
define custom attribute:
<declare-styleable name="ApplicationStyle">
<attr name="colorWeekdaysBg" format="color"/>
</declare-styleable>
Define an application style:
<style name="ApplicationStyle" parent="Theme.AppCompat.NoActionBar">
<item name="android:editTextStyle">#style/EditTextStyle</item>
<item name="colorPrimaryDark">#color/dark_blue</item>
<item name="colorPrimary">#color/dark_blue</item>
<item name="colorAccent">#color/dark_blue</item>
<item name="colorWeekdaysBg">#color/access_weekdays</item>
</style>
Set style in the manifest:
<application
android:name=".App"
android:icon="#drawable/icon_launcher"
android:label="#string/app_name"
android:theme="#style/ApplicationStyle">
Use this attribute in the drawable xml:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:right="-1dp">
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="?colorWeekdaysBg" />
<corners
android:bottomLeftRadius="100dp"
android:topLeftRadius="100dp" />
</shape>
</item>
</layer-list>
But for some reason it does not apply my color to the drawable. It applies a transparent color instead.
One more strange thing is if I replace my ?colorWeekdaysBg with ?colorAccent, which is defined in the Theme.AppCompat, then it applies correct color.
So finally the question: Do you have any idea why it doesn't work, and how to fix it?
As per answer give by mudit here it is a bug in the pre-lollipop OS.
It is reported in Google's Issue Tracker.
In the devices which have Android Lollipop and above OS version it will work fine.
Check below code:
attr.xml
<declare-styleable name="AppTheme">
<attr name="colorWeekdaysBg" format="color|reference" /> <!-- Or you can keep color only. It will be ok -->
</declare-styleable>
You have to set the attribute in the v21 style file. Might be you missed this one.
v21\styles.xml
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:splitMotionEvents">false</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:navigationBarColor">#color/black</item>
<item name="colorWeekdaysBg">#color/access_weekdays</item>
</style>
Create two drawable files to get it work on all devices. One for normal i.e. pre-lollipop version and another for Lollipop and above i.e. v21 drawable.
your_drawable.xml In this you have to set color from the color file.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:right="-1dp">
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#color/access_weekdays" />
<corners
android:bottomLeftRadius="100dp"
android:topLeftRadius="100dp" />
</shape>
</item>
</layer-list>
v21\your_drawable.xml In this file you can set custom attribute like you did.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:right="-1dp">
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="?colorWeekdaysBg" />
<corners
android:bottomLeftRadius="100dp"
android:topLeftRadius="100dp" />
</shape>
</item>
</layer-list>
your_layout.xml In your layout you can give that drawable as below
<Button
android:id="#+id/btnTest"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/your_drawable"
android:text="Test Text" />
Now check the answers of your questions.
But for some reason it does not apply my color to the drawable. It applies a transparent color instead.
Because you may not have defined your attribute in v21 style.xml file
One more strange thing is if I replace my ?colorWeekdaysBg with ?colorAccent, which is defined in the Theme.AppCompat, then it applies the correct color.
Android Studio displays color in preview but when you will run the application and reached on that screen your application will be crash with the Error inflating class error
android.view.InflateException: Binary XML file line #68: Error inflating class Button
So finally the question: Do you have any idea why it doesn't work, and how to fix it?
I think now you have got the idea that why it doesn't work and how to fix it.
Here is the link to what I have in mind.
https://dribbble.com/shots/1407665-Categories/attachments/204971
Is there a popular library anyone knows that can manage this, otherwise I am alright with going the customizing route.
I have my 9 buttons defined in my XML no problem.
Next I know I have to create a xml file in the drawable folder like "button_shape.xml". Then I add this to my code:
android:background="#drawable/button_shape"
I make my button have an image, I assume with:
android:drawableTop="#drawable/buttonImage"
I guess lastly is how do I create a shape that keeps the bottom colour a consistent size with the text. While allowing different button sizes. Also can I easily alternate the colours by setting the style on each button and defining them as so:
<style name ="ButtonTheme.Custom1" parent="Base.Widget.AppCompat.Button.Colored">
<item name="colorPrimary">#android:color/holo_blue_light</item>
<item name="colorPrimaryDark">#android:color/holo_blue_dark</item>
</style>
<style name ="ButtonTheme.Custom2" parent="Base.Widget.AppCompat.Button.Colored">
<item name="colorPrimary">#android:color/holo_green_light</item>
<item name="colorPrimaryDark">#android:color/holo_green_dark</item>
</style>
<style name ="ButtonTheme.Custom3" parent="Base.Widget.AppCompat.Button.Colored">
<item name="colorPrimary">#android:color/holo_red_light</item>
<item name="colorPrimaryDark">#android:color/holo_red_dark</item>
</style>
<style name ="ButtonTheme.Custom4" parent="Base.Widget.AppCompat.Button.Colored">
<item name="colorPrimary">#android:color/holo_orange_light</item>
<item name="colorPrimaryDark">#android:color/holo_orange_dark</item>
</style>
<style name ="ButtonTheme.Custom5" parent="Base.Widget.AppCompat.Button.Colored">
<item name="colorPrimary">#android:color/holo_blue_bright</item>
<item name="colorPrimaryDark">#android:color/holo_blue_light</item>
</style>
My custom shape so far is this, which is close; but how can I make the darker color keep a consistent size while the other moves according to size of button?
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:bottom="10dp">
<shape android:shape="rectangle" >
<size android:height="10dp" />
<solid android:color="#color/colorPrimaryDark" />
</shape>
</item>
<item android:top="120dp">
<shape android:shape="rectangle" >
<size android:height="120dp" />
<solid android:color="#color/colorPrimary" />
</shape>
</item>
</layer-list>
You can use RecyclerView and StaggeredGrid
https://developer.android.com/reference/android/support/v7/widget/StaggeredGridLayoutManager.html
I am using a appcompat theme for my application. Need to know how i can show underline to spinner. It is just showing anchor. I tried setting up underline using android:background but it makes the anchor disappear.
Update your support library and in XML use
Please add this style to your Spinner
style="#style/Base.Widget.AppCompat.Spinner.Underlined"
This is hacky (and not perfect) way to change spinner and underline color in appcompat theme. Main point that I customized Android support library images and xml files to change color.
1) go to support library package and copy 2 images (or download my custom from the bottom of this post)
/your-app/build/intermediates/exploded-aar/com.android.support/appcompat-v7/23.1.0/res/drawable-hdpi/abc_spinner_mtrl_am_alpha.9.png
and
/your-app/build/intermediates/exploded-aar/com.android.support/appcompat-v7/23.1.0/res/drawable-hdpi/abc_textfield_default_mtrl_alpha.9.png
2) Make a copy of those images
3) Change color of abc_spinner_mtrl_am_alpha.9.png (warning: leave black borders as they are, it's for 9 patch)
4) Change color of second bottom line of abc_textfield_default_mtrl_alpha.9.png (you can see in attached small image below)
5) Save and move files to your project drawables
6) Create bottom_line_color.xml drawable:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-6dp" android:left="-6dp" android:right="-6dp">
<shape>
<stroke android:color="#color/brown" android:width="6dp"/>
</shape>
</item>
7) Create spinner_bottom_line.xml
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="#dimen/abc_control_inset_material"
android:insetTop="#dimen/abc_control_inset_material"
android:insetBottom="#dimen/abc_control_inset_material"
android:insetRight="#dimen/abc_control_inset_material">
<selector>
<item android:state_checked="false" android:state_pressed="false">
<layer-list>
<item android:drawable="#drawable/my_custom_abc_textfield_default_mtrl_alpha" />
<item android:drawable="#drawable/my_custom_abc_spinner_mtrl_am_alpha" />
</layer-list>
</item>
<item>
<layer-list>
<item android:drawable="#drawable/my_custom_abc_textfield_default_mtrl_alpha" />
<item android:drawable="#drawable/my_custom_abc_spinner_mtrl_am_alpha" />
</layer-list>
</item>
</selector>
</inset>
P.S. I couldn't achieve same visual style as default spinner (visual changes shown below). If you start using this custom spinner theme you should use it in all project.
So add to values/styles.xml
<style name="My.Spinner.Style" parent="Base.Widget.AppCompat.Spinner.Underlined">
<item name="android:background">#drawable/spinner_bottom_line</item>
</style>
And use it in application like this:
<Spinner
android:id="#+id/account_spinner"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="#style/My.Spinner.Style"
/>
Important:
You should resize spinner and place to various drawables folders. You can find size in same path as I showed above.
There are few popular sizes:
drawables-mdpi 20x26
drawables-hdpi 29x38
drawables-xhdpi 38x50
drawables-xxhdpi 74x98
You can take my customized images from here:
my_custom_abc_spinner_mtrl_am_alpha:
my_custom_abc_textfield_default_mtrl_alpha:
Spinner example is (xxhdpi), line is mdpi (because we don't need various lines in various drawable folders, so we can have only 1).
Visual difference (from android studio xml preview window) is shown here:
First line is my custom underline spinner, second is default Base.Widget.AppCompat.Spinner.Underlined
Applying style="#style/Base.Widget.AppCompat.Spinner.Underlined" didn't show any difference .Then gave android:backgroundTint and android:backgroundTintMode to spinner and it worked.
<Spinner
android:id="#+id/spBookingType"
android:spinnerMode="dropdown"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="#style/Base.Widget.AppCompat.Spinner.Underlined"
android:backgroundTint="#ff000000"
android:backgroundTintMode="src_in" />
in styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:spinnerStyle">#style/holoSpinner</item>
</style>
<style name="holoSpinner" parent="Widget.AppCompat.Spinner.Underlined">
<item name="android:textSize">16sp</item>
<item name="android:textColor">#color/colorPrimary</item>
</style>
========================
in Layout
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp">
<Spinner
android:id="#+id/spinCountry"
android:layout_width="match_parent"

How can i change theme of my app.Buttons and other things are in an ordinary look.i just want to change those ordinary look.
Use appcompat in your app, it gives some of the good things from lollipop to all pre-lollipop supported apps. http://android-developers.blogspot.in/2014/10/appcompat-v21-material-design-for-pre.html
I have mimicked complete material design using appcompat.
Widgets supported by appcompat are:
EditText
Spinner
CheckBox
RadioButton
Switch (use the new android.support.v7.widget.SwitchCompat)
CheckedTextView
For styling button use the below style:
<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>
Also you can use this library to prep up your app with material design, https://github.com/navasmdc/MaterialDesignLibrary
To change button style, you can change its background. Here is an example for you. Follow these steps:
1. Define button background
For example:
<Button
android:id="#+id/myButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="25dp"
android:background="#drawable/button_background" // this is your button background
android:text="#string/myButton"
android:textColor="#color/white"/>
2. Create a new folder in res folder
Right click on res folder in your project > New > Folder. Name it with drawable.
3. Create a new xml file for your button background
Here, we can name it with button_background.xml. You may rename it later. Place it in drawable folder. So, fill it with:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<!-- view background color-->
<solid android:color="#color/your_background_color" >
</solid>
<!-- If you want to add some padding -->
<padding
android:left="5dp"
android:top="5dp"
android:right="5dp"
android:bottom="5dp" />
<!-- Here is the corner radius -->
<corners
android:radius="6dp" >
</corners>
</shape>
And, completed... For information about changing app's theme, this is a reference for you: Styles and Themes
I am very new to Android Studio. As a beginner I have created a simple app just for testing purpose and to view the appearance of Android studio material theme. I am currently working with latest version ie. L preview - Studio 0.8.2 version.
Here, I have just created textview, edittext, radio buttons and checkboxes. When I select male or female, it appears sky blue color. Could I be able to change sky blue color as a green or yellow color?
I do not know what is the name for that. From the picture can able to see edittext, radio buttons and checkboxes selected state as a sky blue color. When I try to click or select anything then those checkboxes or radio buttons need to change from default color to other colors like green or yellow!
Code
In res/values/styles.xml,
<resources>
<!-- Base application theme. -->
<color name="custom_theme_color">#b0b0ff</color>
<style name="CustomTheme" parent="android:Theme.Material">
<item name="android:colorBackground">#color/custom_theme_color</item>
</style>
</resources>
In Android Studio Manifest.xml,
android:theme="#style/CustomTheme" >
Is there any other possible to change from default sky blue color to green or yellow or purple?
Is there any other way to change default sky blue color theme to other colors like pink or green?
How could I do this?
First Method:
In res/values-v21/styles.xml,
<style name="AppTheme" parent="android:Theme.Material.Light.DarkActionBar">
<item name="android:colorAccent">#color/custom_theme_color</item>
<item name="android:colorPrimaryDark">#color/custom_theme_color</item>
<item name="android:colorPrimary">#color/custom_theme_color</item>
</style>
The above code is simple and working well. In Android studio, it could be able to change from default sky blue color to any other colors like pink or green!
Second Method:
Create 3 files under xml ie. res/xml such as checked.xml, unchecked.xml and custom_checkbox.xml
checked.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="2px" android:color="#FF00FF" />
<size android:height="20dp" android:width="20dp"/>
</shape>
unchecked.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="2px" android:color="#ffc0c0c0" />
<size android:height="20dp" android:width="20dp"/>
</shape>
custom_checkbox.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="#xml/checked" />
<item android:state_pressed="true"
android:drawable="#xml/checked" />
<item android:drawable="#xml/unchecked" />
</selector>
From above second method, it (customized file) also could be able to create any shapes and colors based on our requirements. Even we can be able to customize the style, shapes and themes for a widget by using 2nd method.
Above two methods are working fine for me!
Also in from v23 with AppCompat you can use android.support.v7.widget.AppCompatCheckBox and change CheckBox style like this:
<android.support.v7.widget.AppCompatCheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:theme="#style/CheckBox"
/>
where in style.xml:
<style name="CheckBox" parent="Widget.AppCompat.CompoundButton.CheckBox">
<item name="colorControlNormal">#color/checkbox_normal</item> <!-- border color -->
<item name="colorControlActivated">#color/checkbox_activated</item> <!-- fill color -->
<item name="colorControlHighlight">#color/checkbox_highlight</item> <!-- animation color -->
</style>
