colorButtonNormal has no effect?

I am trying to apply a unified style on my button.
This is my v21/styles.xml
<style name="DefaultButton" parent="Widget.AppCompat.Button.Colored">
<item name="android:colorButtonNormal">#f00</item>
<item name="android:textColor">#color/colorTextSecondary</item>
</style>
I apply this to my button like this
<Button
android:id="#+id/submit_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginTop="#dimen/unit_large"
style="#style/DefaultButton"
android:text="Lemme In!" />
nothing fancy going on in here. Yet the color of my button doesn't change. Did something change over the material support packages? I am using '25.3.1'
Actually all of this is part of a greater effort I have to do to change the default button style of the application like this
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:buttonStyle">#style/DefaultButton</item>
</style>
I would then remove the individual styling attributes on all the buttons

Change this style="#style/DefaultButton" to
android:theme="#style/DefaultButton"

Customizing TextInputLayout's colors on 4.x doesn't work

I'm doing the following in my syles.xml
<style name="TextLabel" parent="TextAppearance.AppCompat">
<!-- Hint color and label color in FALSE state -->
<item name="android:textColorHint">#color/app_white</item>
<item name="android:textColorHighlight">#color/app_white</item>
<item name="android:textColorLink">#color/app_white</item>
<item name="android:textSize">#dimen/app_text_small</item>
<!-- Label color in TRUE state and bar color FALSE and TRUE State -->
<item name="colorAccent">#color/app_white</item>
<item name="colorControlNormal">#color/app_white</item>
<item name="colorControlActivated">#color/app_white</item>
</style>
and then setting the style to the TextInputLayout like so: android:theme="#style/TextLabel"
My problem is that it won't set the colors of the bottom border to white, nor the floating text. At least not on 4.1.1 and 4.2.2 Any ideas? On 5.0 and above it works just fine.

Create a style for your text appearance in this way.
<style name="TextAppearence.App.TextInputLayout" parent="#android:style/TextAppearance">
<item name="android:textColor">#color/colorPrimary</item>
</style>
Implementation code for your layout is given below.
<android.support.design.widget.TextInputLayout
android:id="#+id/input_layout_email"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
app:hintTextAppearance="#style/TextAppearence.App.TextInputLayout">
<EditText
android:id="#+id/et_Email_Login"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:hint="#string/hint_email" />
</android.support.design.widget.TextInputLayout>

Apparently the problem is that pre Lollipop the OS doesn't know the android:theme attribute. So what I did was move all the custom attributes from the TextLabel style to the maine style that overrides the app compat one directly.
i.e.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
This seemed to be just fine on pre Lollipop.

ImageButton background color with appcompat

I've got problems to have a good background from an AppCompatImageButton, just to try I'm comparing this two layouts:
<android.support.v7.widget.AppCompatImageButton
android:id="#+id/imageButtonI"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
android:contentDescription="#string/icolor"
android:tint="#color/accent"
app:srcCompat="#drawable/magnify"/>
<ImageButton
android:id="#+id/imageButtonS"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
android:contentDescription="#string/scolor"
android:tint="#color/accent"
android:src="#drawable/magnify"/>
and the style file:
<style name="AppBaseTheme" parent="android:Theme.Material">
<item name="android:colorPrimary">#color/primary</item>
<item name="android:colorPrimaryDark">#color/primaryDark</item>
<item name="android:colorAccent">#color/accent</item>
</style>
As you can see from this image however, the background of ImageButton is "normal" while there isn't any background in the appcompat one. How can I have the "normal" background using AppCompatImageButton?

A good way to style the Button is to use the style #style/Widget.AppCompat.Button.Colored.
The Widget.AppCompat.Button.Colored style extends the Widget.AppCompat.Button style and applies automatically the accent color you selected in your app theme.
<Button
style="#style/Widget.AppCompat.Button.Colored"
/>
To customize the background color without changing the accent color in your main theme you can create a custom theme for your Button using the android:theme attribute and extending the ThemeOverlay theme.
<Button
style="#style/Widget.AppCompat.Button.Colored"
android:theme="#style/MyButtonTheme"/>
defining the following theme:
<!-- res/values/themes.xml -->
<style name="MyButtonTheme" parent="ThemeOverlay.AppCompat.Light">
<item name="colorAccent">#color/my_color</item>
</style>

I am not sure which version of support library are you using, but before there was bug in the library which is reported here,
https://code.google.com/p/android/issues/detail?id=78428
But they have resolved it in the latest update,
Yes, it appears to work now with the introduction of
android.support.v7.widget.AppCompatButton in AppCompat v22.1.0, color
can be controlled at overall theme level with "colorButtonNormal".

http://chris.banes.me/2015/04/22/support-libraries-v22-1-0/
for theme
<item name="colorButtonNormal">#color/button_color</item>
for version 21
<item name="android:colorButtonNormal">#color/button_color</item>
Hope this will help you.
Thanks

Material Raised Button with Default Background

I am trying to create a button whose text color is the colorAccent and whose background color is the default background color.
It looks like this:
I have tried default styles, but non of them have worked. Currently I have something like this but doesn't work:
styles.xml :
<style name="AppTheme.ButtonRaised" parent="Widget.AppCompat.Button.Colored">
<item name="colorButtonNormal">#android:color/transparent</item>
<item name="android:textColor">#color/colorAccent</item>
</style>
And layout:
<Button
app:theme="#style/AppTheme.ButtonRaised"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="date" />
And I am getting something like this:
I am not getting any effect of style or theme here. I have also tried with style tag, but it doesn't work.

apply theme with a style like this
<style name="ThemeButtonBlue" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorAccent">#color/colorPrimary</item>
<item name="colorButtonNormal">#android:color/transparent</item>
<item name="colorControlNormal">#color/white</item>
<item name="colorControlActivated">#color/colorPrimaryDark</item>
<item name="colorControlHighlight">#color/colorPrimary</item>
</style>

I am also struggling to do this effect. I could achieve something similar, but I don't know if its "material design approved".
I set the style to their button borderless colored and the elevation to 2dp because on material design they say that "Raised buttons have a default elevation of 2dp". But they don't give you xml layout examples which is annoying -_-
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
style="#style/Base.Widget.AppCompat.Button.Borderless.Colored"
android:elevation="2dp"
android:text="Button"/>
Keep in mind that the elevation tag does not show a shadow pre Lollipop devices.

Android Button background color not changing

In this android project im creating a default button style.
my styles.xml
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:buttonStyle">#style/ButtonStlye123</item>
</style>
<style name="ButtonStlye123" parent="android:style/Widget.Button">
<item name="android:textSize">19dp</item>
<item name="android:layout_margin">8dp</item>
<item name="android:padding">8dp</item>
<item name="android:textColor">#color/ColorDivider</item>
<item name="android:background">#color/ColorAccent</item>
</style>
my button in a fragment.
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/btnLogin"
android:id="#+id/btn_login"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:theme="#style/ButtonStlye123"
android:onClick="login" />
In the preview in android studio it looks exactly like I want, but when I run the app on my device the background color is gray ("default button color"). If i change the text color in my styles.xml like:
<item name="android:textColor">#color/ColorPrimary</item>
it changes (also on my device) so the custom style is loading, i tryd different colors (that worked for the text) for the button but it wont change.
Why isnt my background color loading?

Try use AppCompactButton
instead of
<Button
use
<androidx.appcompat.widget.AppCompatButton
that will do the trick
Update: 01/06/2021
Found out that the above will not work on earlier Android versions.
For materiel design Button use
app:backgroundTint="#color/green"

Please Use androidx.appcompat.widget.AppCompatButton instead of Button.
<androidx.appcompat.widget.AppCompatButton
android:id="#+id/button_id_Login"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:layout_below="#id/textInnputLayout_editText_id_password"
android:layout_centerHorizontal="true"
android:layout_marginTop="50dp"
android:text="#string/Login_screen_button_text"
android:background="#drawable/login_button_style"
android:textAllCaps="false">
</androidx.appcompat.widget.AppCompatButton>

You might be using targetSdkVersion 30 material theme
The solution is change theme.xml style
From
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
To
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
Replace with
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
Changing MaterialComponents to AppCompat works for me..

I think you need to change your attribute from "theme" to "style". These files are intended for different things, so are used differently.
Style is used to assign attributes to individual views or components, and Theme is used to apply attributes to the entire app.
So try this instead:
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/btnLogin"
android:id="#+id/btn_login"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
<!-- This attribute was changed -->
android:style="#style/ButtonStlye123"
android:onClick="login" />
You should also split these different types of XML into the correct files as appropriate (styles.xml and themes.xml - instead of keeping them all in the same file). This is convention, and won't effect the code compilation or execution, but is recommended as a code style.

Use this attribute backgroundTint it will help you. It work for me. Example :
android:backgroundTint="#color/md_orange_800"

if you are using Android Studio Version 4.1 and above (Beta)
check your themes.xml file in values.
<style name="Theme.NavaFlashLightV4" parent="Theme.MaterialComponents.DayNight.NoActionBar">
<!-- Primary brand color. -->
<item name="colorPrimary">#color/purple_500</item>
<item name="colorPrimaryVariant">#color/purple_700</item>
<item name="colorOnPrimary">#color/white</item>
</style>
change the attribute to #null
<style name="Theme.NavaFlashLightV4" parent="Theme.MaterialComponents.DayNight.NoActionBar">
<!-- Primary brand color. -->
<item name="colorPrimary">#null</item> <!-- HERE -->
<item name="colorPrimaryVariant">#color/purple_700</item>
<item name="colorOnPrimary">#color/white</item>
</style>
for other old versions of Android Studio
just change this attribute
<item name="colorPrimary">#color/colorPrimary</item>
to
<item name="colorPrimary">#color/#null</item>
finally set the background of the button to the drawable icon you want.
example:
<Button
android:id="#+id/btnSwitch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#drawable/ic_launcher_background" /> <!--the drawable you want-->

You only need to change your App Theme from Theme.MaterialComponents.DayNight.DarkActionBar to Theme.AppCompat.Light.NoActionBar inside styles.xml file
example :
from : style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar"
To : style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"

your style should be like this....
<style name="ButtonStlye123" >
<item name="android:textSize">19dp</item>
<item name="android:layout_margin">8dp</item>
<item name="android:padding">8dp</item>
<item name="android:textColor">#color/ColorDivider</item>
<item name="android:background">#color/ColorAccent</item>
</style>
and in layout
<Button
android:id="#+id/btn3"
style="#style/ButtonStlye123"
android:layout_width="#dimen/sixzero"
android:layout_height="#dimen/sixzero"
android:text="3" />

I am using targetSdk 30 and compileSdk 32 and I am using Button widget. Android Studio version 2021.1.1
In my case, following change worked,
In AndroidManifest.xml, under "application" tag changing "android:theme" from
android:theme="#style/Theme.AppCompat.Light.NoActionBar"
to
android:theme="#style/Theme.MaterialComponents.DayNight.NoActionBar"
I moved to Theme.AppCompat.Light.NoActionBar to remove the title bar. At first I tried to change "style" to "Theme.AppCompat.Light.NoActionBar" inside themes.xml but it didn't work for me.
