Change Color from material outlined button doesn't work

I want to change the color of the active toggle button. But just the change of the rippleColor makes a difference.
I wish to customize the background color of the active button and the text color.
<style name="ToggleButtonGroupStyle" parent="Widget.MaterialComponents.Button.OutlinedButton">
<item name="rippleColor">#color/colorAccent</item>
</style>
In the following toggleButtonGroup I used this style from above:
<com.google.android.material.button.MaterialButtonToggleGroup
android:id="#+id/priority_btn_group"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentLeft="true"
app:selectionRequired="true"
app:singleSelection="true"
app:checkedButton="#+id/btn_one"
>
<com.google.android.material.button.MaterialButton
android:id="#+id/btn_one"
style="#style/ToggleButtonGroupStyle"
android:layout_width="#dimen/priority_btn_width"
android:layout_height="wrap_content"
android:shadowColor="#color/project_text"
android:text="0" />
<com.google.android.material.button.MaterialButton
style="#style/ToggleButtonGroupStyle"
android:layout_width="#dimen/priority_btn_width"
android:layout_height="wrap_content"
android:text="!" />
<com.google.android.material.button.MaterialButton
style="#style/ToggleButtonGroupStyle"
android:layout_width="#dimen/priority_btn_width"
android:layout_height="wrap_content"
android:text="!!" />
<com.google.android.material.button.MaterialButton
style="#style/ToggleButtonGroupStyle"
android:layout_width="50dp"
android:layout_height="wrap_content"
android:text="!!!" />
</com.google.android.material.button.MaterialButtonToggleGroup>
Could anybody give me a hint what the problem here is?
Thanks :)

The background color of the checked buttons is based on the colorPrimary attribute.
You can use:
<com.google.android.material.button.MaterialButton
android:id="#+id/btn_one"
style="?attr/materialButtonOutlinedStyle"
android:theme="#style/ThemeOverlay.Custom.Button"
with:
<style name="ThemeOverlay.Custom.Button" parent="">
<item name="colorPrimary">#color/....</item>
</style>
or you can use a custom style with:
<com.google.android.material.button.MaterialButton
android:id="#+id/btn_one"
style="#style/ToggleButtonGroupStyle"
with:
<style name="ToggleButtonGroupStyle" parent="Widget.MaterialComponents.Button.OutlinedButton">
<item name="backgroundTint">#color/custom_selector</item>
</style>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#color/..." android:state_checked="true"/> <!-- selected color -->
<item android:color="#android:color/transparent" android:state_checked="false"/>
</selector>

selected color of MaterialToggleButton to a solid color

Not able to make the selected color of MaterialToggleButton to a solid color, only a transparent shade of color primary is shown.
I tried the below set of code and the out image is shown below.
Button theme in styles
<style name="ThemeButtonColorToggle" parent="AppTheme">
<item name="colorPrimary">#color/colorOrange</item>
<item name="colorButtonNormal">#color/colorOrange</item>
<item name="android:backgroundTint">#color/black</item>
<item name="strokeColor">#color/colorOrange</item>
<item name="strokeWidth">#dimen/mtrl_btn_stroke_size</item>
<item name="colorOnPrimary">#color/colorOrange</item>
<item name="colorOnPrimarySurface">#color/colorOrange</item>
</style>
XML code
<com.google.android.material.button.MaterialButtonToggleGroup
android:id="#+id/toggleGroup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:checkedButton="#id/btnAndroid"

android:layout_height="wrap_content"
android:textIsSelectable="true"
android:theme="#style/ThemeButtonColorToggle"
android:textColor="#android:color/white"
android:textColorHighlight="#color/colorOrange"
android:text="Android" />
<com.google.android.material.button.MaterialButton
android:id="#+id/btniOS"
android:layout_width="wrap_content"
android:textIsSelectable="true"
android:textColor="#android:color/white"
android:theme="#style/ThemeButtonColorToggle"
android:layout_height="wrap_content"
android:text="iOS" />
</com.google.android.material.button.MaterialButtonToggleGroup>
I require to get a solid color as shown below
can anyone please help me to sort out

The background color of the MaterialButton is defined by the backgroundTint attribute.
The default value is:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="?attr/colorPrimary" android:state_enabled="true"/>
<item android:alpha="0.12" android:color="?attr/colorOnSurface"/>
</selector>
You can change it in the xml layout or you can define a custom style:
<com.google.android.material.button.MaterialButton
style="#style/ButtonStyle"
.. />
with:
<style name="ButtonStyle" parent="Widget.MaterialComponents.Button">
<item name="backgroundTint">#color/your_button_background_selector</item>
...
</style>

RatingBar with pink background when holding

My RatingBar is pretty regular, when selected appears like this
But when touching (and holding) them, all unrated stars are pink, like this
Why does this happen?
The xml:
<RatingBar
android:id="#+id/ratingBarSchedulesRatingTour"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:numStars="5"
android:progressTint="#color/yellow_star"
android:secondaryProgressTint="#color/yellow_star"
android:stepSize="1" />
#color/yellow_star is on colors.xml as #F1CD1E

You can use android:progressBackgroundTint attribute on RatingBar to override background color:
android:progressBackgroundTint="#ABABAB"

Create Style and color what you want (press/normal)
<style name="RatingBar" parent="Theme.AppCompat">
<item name="colorControlNormal">#F1CD1E</item>
<item name="colorControlActivated">#F1CD1E</item>
</style>
<RatingBar
android:id="#+id/ratingBarSchedulesRatingTour"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:numStars="5"
android:progressTint="#F1CD1E"
android:theme="#style/RatingBar"
android:secondaryProgressTint="#F1CD1E"
android:stepSize="1" />

RatingBar with small white stars

The following is the xml for my rating bar.
<RatingBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="?android:attr/ratingBarStyleSmall"
android:numStars="5"
android:isIndicator="true"
android:stepSize="0.5"
android:rating="4.5"/>
I am happy with its size but I would like to stars to be white on grey (white for filled and grey for empty).
I am looking at this tutorial (http://www.materialdoc.com/rating-bar/) but I am not sure how to adapt the style to suit the small appearance.

You can try drawable
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background"
android:drawable="#drawable/star_off" />
<item android:id="#android:id/secondaryProgress"
android:drawable="#drawable/star_off" />
<item android:id="#android:id/progress"
android:drawable="#drawable/star_on" />
</layer-list>
<RatingBar
android:id="#+id/ratingBar2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:progressDrawable="#drawable/custom_ratingbar_selector"
android:isIndicator="true"
android:stepSize="0.5"
android:rating="4.5" />

you can use progressTint for this purpose
<RatingBar
android:id="#+id/vendorRatingBarValue"
style="?android:attr/ratingBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignRight="#+id/reviewerName"
android:clickable="false"
android:gravity="left|center"
android:isIndicator="true"
android:numStars="5"
android:progressTint="#color/white"
android:transformPivotX="0dp"
/>

you would need to use the attributes
android:backgroundTint="#color/grey"
android:progressTint="#color/white"
so..
<RatingBar
android:id="#+id/rb_doctor"
style="?android:attr/ratingBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:backgroundTint="#color/grey"
android:numStars="5"
android:progressTint="#color/white"
android:rating="0"
android:secondaryProgressTint="#color/white"
android:stepSize="1.0"
/>

This is simple example of RatingBar.
Custom white and gray star can possible with custom theme for this and specify small size so size of rating bar star will be same as default small size theme.
You have to create drawable for custom rating bar and make sure about the size of rating bar because here height of rating bar matters a lot.i mean if your star image is size of 13dp height and rating bar is 17dp height than it will stretch the rating bar so make sure about height.
Here is simple example of how can create custom selector for rating bar.
Star Drawable
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:state_window_focused="true" android:drawable="#drawable/ic_star_empty_small" />
<item android:state_focused="true" android:state_window_focused="true" android:drawable="#drawable/ic_star_empty_small" />
<item android:state_selected="true" android:state_window_focused="true" android:drawable="#drawable/ic_star_empty_small" />
<item android:drawable="#drawable/ic_star_empty_small" />
</selector>
Style for rating bar
<style name="foodRatingBar" parent="#android:style/Widget.RatingBar">
<item name="android:progressDrawable">#drawable/inf_full_ratingbar</item>
<item name="android:minHeight">20dip</item>
<item name="android:width">20dip</item>
<item name="android:height">20dip</item>
<item name="android:maxHeight">20dip</item>
</style>
And than use custom style for rating bar like:
<RatingBar
android:id="#+id/ratingBarFlight"
style="#style/StarRatingBar"
android:layout_width="wrap_content"
android:layout_height="#dimen/rating_bar_height"
android:layout_gravity="center_horizontal"
android:layout_marginTop="#dimen/library_screen" />

Android: Color of stars in RatingBar, that already uses style

I want to change colour of RatingBar stars in every mode(highlighted, notHighlited, progress), but I already use style Widget.AppCompat.RatingBar.
I don't want to change style cause, I like star shapes and staff, I only want to change star colors, Is it possible?
Here's my code:
<RatingBar
android:id="#+id/ratingBar"
style="#style/Widget.AppCompat.RatingBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:stepSize="1.0"
android:layout_gravity="center_horizontal"
android:rating="0.0" />

Use styles:
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background" android:drawable="#drawable/background" />
<item android:id="#android:id/secondaryProgress" android:drawable="#drawable/secondary_progress" />
<item android:id="#android:id/progress" android:drawable="#drawable/progress" />
</layer-list>
You can use this style following way. Add this line to the RatingBar:
android:progressDrawable="#drawable/rating"
