Android android:buttonStyle not applied - android

I have the following code in my styles.xml:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:buttonStyle">#style/ButtonStyle</item>
</style>
<style name="ButtonStyle" parent="#android:style/Widget.Button">
<item name="android:background">#FF00FF</item>
<item name="android:textColor">#color/material_deep_teal_500</item>
</style>
This is supposed to print the button background in Pink (#FF00FF) and text in teal, but it not applies to my buttons.
I had two kind of views, normal Button () and ButtonLinearLayout, that gets the current them default Button backgroundm, and apply it to LinearLayout.
But it's not changed when i try to apply it to my views / default button.

The simplest way is to create a res/drawable/button_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="#color/material_deep_teal_500" > //text color when button is pressed
<shape>
<solid
android:color="#ff00ff"/> //background color when button is pressed
</shape>
</item>
<item android:color="#color/material_deep_teal_500"> //text color when button is normal
<shape>
<solid android:color="#ff00ff"/> //background color when button is normal
</shape>
</item>
</selector>
Now put android:background="#drawable/button_selector" in xml having button

RadioButton focus background shape

I want to add focus ripple effect to whole RadioButton, but there is something strange is happening to it when I try to use ripple effect with highlight. In the picture, left is what I get and right is what I want:
background_drawable:
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/colorAccent">
<item android:id="#android:id/mask">
<shape android:shape="rectangle">
<solid android:color="#android:color/white"/>
</shape>
</item>
</ripple>
styles.xml
<style name="RadioButtonStyle" parent="Widget.AppCompat.CompoundButton.RadioButton">
<item name="android:background">#drawable/radio_button_background</item>
</style>
This happens only If I try to use ripple effect and not if I try to use only shape with selector and state_focused=true as background. For now my workaround is to use warpper View class for RadioButton and set background into it. Is there any way to get background as in the picture but without any additional code? Thanks.
The solution is to set the button attribute to null and set the drawableStart attribute in styles for the radio button:
<style name="RadioButtonStyle" parent="Widget.AppCompat.CompoundButton.RadioButton">
<item name="android:button">#null</item>
<item name="android:drawableStart">#drawable/radio_button_selector</item>
<item name="android:drawablePadding">4dp</item>
<item name="android:background">#drawable/radio_button_background</item>
<item name="android:gravity">center_vertical</item>
<item name="android:paddingStart">8dp</item>
<item name="android:paddingEnd">8dp</item>
<item name="android:paddingTop">11dp</item>
<item name="android:paddingBottom">11dp</item>
</style>
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
<!-- Customize your theme here. -->
<item name="radioButtonStyle">#style/RadioButtonStyle</item>
<item name="android:radioButtonStyle">#style/RadioButtonStyle</item>
</style>
After that focus works as aspected and You can add background to the radio button as You want

How to override Theme.AppCompat.Light.DarkActionBar theme for edittext

I am trying to create a style for EditText (MyEditText), which inherits from base theme and added extra property settings.
<style name="MyMaterialTheme" parent="MyMaterialTheme.Base">
<item name="homeAsUpIndicator">#drawable/ic_back_indicator</item>
</style>
<style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="MyEditText" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:background">#dbffb1</item>
</style>
When applied MyEditText style to EditText control, existing styles (from theme) seems to be overridden (like line under EditText vanished). Same thing happens when background is changed for EditText in the layout.
I am using targetSdkVersion 23.
I like to know what is the proper method to override a single property from default theme.
Here is the code for EditText in layout (as asked by #3amoura):
<EditText android:layout_width="match_parent"
android:layout_height="82dp"
android:id="#+id/et_description"
android:inputType="textMultiLine|textLongMessage"
android:lines="10"
android:hint="Describe your complaint in details"
android:gravity="top"
style="#style/MyEditText" />
The style of MyEditText should inherit from Widget.AppCompat.EditText instead of Theme.AppCompat.Light.DarkActionBar such that it will be
<style name="MyEditText" parent="Widget.AppCompat.EditText">
<item name="android:background">#dbffb1</item>
Then you use the style in the EditText xml
Edited
If you are only trying to add a color of the Line drawn -> setBackgroundTint
If you want to change both the background color and the line color, then custom layer-list or selector will be the only option. A sample layer-list
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#dbffb1" /> <!-- background color-->
</shape>
</item>
<item
android:top="-2dp"
android:right="-2dp"
android:left="-2dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:width="1dp"
android:color="#color/colorAccent" /> <!-- color of stroke -->
</shape>
</item>
</layer-list>

Android: toggle text color of ToggleButton

To create a custom ToggleButton, I've defined a new style in /res/values/styles.xml:
<style name="myToggleButton">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:textColor">#000000</item>
<item name="android:background">#drawable/my_toggle_button</item>
</style>
and I then use a selector to specify how the button's states look in /res/drawable/my_toggle_button.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true">
<shape>
[...]
</shape>
</item>
<item android:state_checked="false"
<shape>
[...]
</shape>
</item>
</selector>
How can I modify this setup to toggle the text color of the button when the state changes?
Create a similar state list for the text colors you would like, and place it in res/color, e.g.
res/color/toggle_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="#070" />
<!-- Default State -->
<item android:color="#A00" />
</selector>
Then set this resource as the text color of the button:
<item name="android:textColor">#color/toggle_color</item>
P.S., it's good practice to have the last item in a selector not have any state flags attached (i.e. a default state) rather than defining it with the inverse of the above states.

Changing text color on press

The rows of my list have a custom selector. The background for this selector is color A when not pressed and color B when pressed. A TextView on the item's layout is colored B for juxtaposition when the list item is not pressed.
However, I would like the text color to change to color A while the row is being pressed, to juxtapose with the new background color.
How do I accomplish this?
You can style your text with a textColor drawable:
<style name="listLabel">
<item name="android:textSize">16sp</item>
<item name="android:textColor">#drawable/list_selector_text</item>
</style>
and drawable/list_selector_text looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:state_pressed="true" android:color="#color/white" />
<item android:state_focused="true" android:color="#color/offwhite" />
<item android:state_pressed="true" android:color="#color/white" />
<item android:color="#color/black" />
</selector>

How to set the text style of a button in selectors?

Button selectors allows to define a background for each state of the button, but how can the button's text style be defined for each state? My objective is to grey out a button when disabled. So I set a greyed out background to the disable state of the button, but the only way I found to also grey out the text is to change it's color dynamically when I disable the button...
Anybody can help?
Thanks
<style name="srp_button" parent="#android:style/Widget.Button">
<item name="android:background">#drawable/btn_default</item>
<item name="android:textColor">#ffffff</item> <!-- How to specify different color for different state? -->
<!-- more stuff -->
</style>
drawable/btn_default.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true"><shape>
<solid android:color="#color/pink" />
<corners android:radius="6dp" />
</shape></item>
<item><shape>
<solid android:color="#000000" />
<corners android:radius="6dp" />
</shape></item>
</selector>
Well!
You can define the Text color for all 4 state, similarly as you defined background for the Button. For example:
file name: /res/color/text_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:color="#440000"/>
<item android:state_focused="true" android:color="#004400"/>
<item android:state_pressed="true" android:color="#000044"/>
<item android:color="#444"/>
</selector>
Take this file into your Button Style like this:
<style name="srp_button" parent="#android:style/Widget.Button">
<item name="android:background">#drawable/btn_default</item>
<item name="android:textColor">#color/text_color</item> <!-- Here is specified text color -->
</style>
