How to set text and/or background color of Cut Copy Paste

I am using a custom Dark Theme in my app. Everything is doing okay, except for the Cut Copy Paste dialog that appears as a solid black square.
Surely there is a style that determines that, but I can't find it, or an answer that addresses this directly. Min API is 16.
<style name="DarkTheme" parent="AppTheme.NoActionBar">
<item name="colorPrimary">#color/blackBackground</item>
<item name="colorPrimaryDark">#color/blackBackground</item>
<item name="colorAccent">#color/yellow</item>
<item name="android:textColor">#color/whiteText</item>
<item name="android:background">#color/blackBackground</item>
<item name="buttonStyle">#style/darkButtonStyle</item>
<item name="spinnerStyle">#style/darkSpinnerStyle</item>
</style>
<style name="darkButtonStyle" parent="#android:style/Widget.Button">
<item name="android:layout_width">fill_parent</item>
<item name="android:textColor">#color/whiteText</item>
<item name="android:textSize">16sp</item>
<item name="android:padding">10dp</item>
<item name="android:textStyle">bold</item>
<item name="android:background">#color/darkBackground</item>
<item name="android:gravity">center</item>
<item name="android:textAllCaps">true</item>
</style>
<style name="darkSpinnerStyle" parent="Widget.AppCompat.Spinner">
<item name="android:background">#color/blackBackground</item>
<item name="android:paddingTop">0dp</item>
<item name="android:layout_marginStart">1dp</item>
<item name="android:layout_marginLeft">1dp</item>
<item name="android:layout_width">0dp</item>
<item name="android:layout_height">0dp</item>
</style>

I was having the same issue when regarding to MaterialAlertDialog. I was able to fix it using backgroundTint instead of background in styles. This is how:
Before
<style name="materialAlertDialog" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="android:background">#color/colorPrimaryDark</item>
<item name="materialAlertDialogTitleTextStyle">#style/TitleTextStyle</item>
<item name="materialAlertDialogBodyTextStyle">#style/BodyTextStyle</item>
<item name="buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
<item name="buttonBarNegativeButtonStyle">#style/NegativeButtonStyle</item>
</style>
This will be enough to repropduce the error that you are saying... So what i did was changing background for backgroundTint...
After
<style name="materialAlertDialog" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="android:backgroundTint">#color/colorPrimaryDark</item>
<item name="materialAlertDialogTitleTextStyle">#style/TitleTextStyle</item>
<item name="materialAlertDialogBodyTextStyle">#style/BodyTextStyle</item>
<item name="buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
<item name="buttonBarNegativeButtonStyle">#style/NegativeButtonStyle</item>
</style>
It seems like when you set a background and the dialog is created, the toolbar of copy/paste menu was changing his background in some weird way that i cant explain.
So this is not the exact answer for your problem but it may help you.
Note: Try removing background attr of your style. I have a dark theme and there is no need to use it. Just simple use <style name="AppTheme" parent="Theme.MaterialComponents.DayNight"> instead of <style name="DarkTheme" parent="AppTheme.NoActionBar">.

Is there a list or pattern of overriding control themes?

I know that you can globally set control themes using a styles.xml and referencing a theme for activities.
<?xml version="1.0" encoding="utf-8" ?>
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#color/PrimaryColor</item>
<item name="colorPrimaryDark">#color/PrimaryDarkColor</item>
<item name="colorAccent">#color/SecondaryColor</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:statusBarColor">#color/PrimaryDarkColor</item>
<item name="android:textColor">#color/PrimaryTextColor</item>
<item name="android:datePickerStyle">#style/datepicker</item>
<item name="android:textViewStyle">#style/textView</item>
<item name="android:spinnerStyle">#style/spinner</item>
<item name="android:checkBoxStyle">#style/CheckboxStyle</item>
<item name="android:dropDownListViewStyle">#style/DropDownStyle</item>
</style>
<style name="datepicker">
<item name="colorPrimary">#color/PrimaryColor</item>
<item name="colorPrimaryDark">#color/PrimaryDarkColor</item>
<item name="colorAccent">#color/SecondaryColor</item>
</style>
<style name="spinner">
<item name="android:background">#drawable/SpinnerBackground</item>
</style>
<style name="textView" parent="android:Widget.TextView">
<item name="android:textSize">#dimen/defaultTextViewSize</item>
</style>
<style name="DialogThemeButton">
<item name="android:background">#color/PrimaryDarkColor</item>
</style>
<style name="DialogThemeTextAppearance">
<item name="android:textColor">#color/PrimaryTextColor</item>
</style>
<style name="DropDownStyle" parent="android:Widget.ListView.DropDown">
<item name="android:divider">#drawable/SpinnerDivider</item>
<item name="android:dividerHeight">1dp</item>
</style>
<style name="CheckBoxStyle" parent="android:Widget.ListView.DropDown">
<item name="android:divider">#drawable/SpinnerDivider</item>
<item name="android:dividerHeight">1dp</item>
</style>
<style name="DialogTheme" parent="Theme.AppCompat.Dialog.Alert">
<item name="android:background">#android:color/white</item>
<item name="colorAccent">#color/PrimaryDarkColor</item>
<item name="android:textColor">#color/PrimaryDarkColor</item>
<item name="android:textColorPrimary">#color/PrimaryTextColor</item>
<!-- <item name="android:textAppearanceMedium">#style/DialogThemeTextAppearance</item>-->
<item name="android:buttonBarButtonStyle">#style/DialogThemeButton</item>
</style>
</resources>
Question:
Is there some way to find the appropriate item names for any kind of control?
I think i should be able to find it on google using my question, but i cannot.

A strict pattern would have been nice but i guess that'll do:

Parent style for TextView style with AppCompat usage

What parent style should I use if I want to set global textViewStyle and maintain backward compatibility with AppCompat? I can't find something like Widget.AppCompat.TextView :
<style name="Base_AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:textViewStyle">#style/GlobalTextViewStyle</item>
</style>
<style name="GlobalTextViewStyle" parent="?????">
<item name="android:textAppearance">#style/TextAppearance.AppCompat.Medium</item>
</style>

You just need to extend TextAppearance.AppCompat style overriding necessary values:
<style name="Base_AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:textAppearance">#style/MyTextAppearance</item>
</style>
<style name="MyTextAppearance" parent="TextAppearance.AppCompat">
<item name="android:textColor">?android:textColorPrimary</item>
<item name="android:textColorHint">?android:textColorHint</item>
<item name="android:textColorHighlight">?android:textColorHighlight</item>
<item name="android:textColorLink">?android:textColorLink</item>
<item name="android:textSize">#dimen/abc_text_size_body_1_material</item>
<item name="textColor">?textColorPrimary</item>
<item name="textColorHighlight">?textColorHighlight</item>
<item name="textColorHint">?textColorHint</item>
<item name="textColorLink">?textColorLink</item>
<item name="textSize">16sp</item>
<item name="textStyle">normal</item>
</style>

If you want to set this style for all your TextView's in your app, you can do something like this:
<resources>
<style name="YourTheme" parent="android:YourParentThTheme">
<item name="android:textViewStyle">#style/GlobalTextViewStyle </item>
</style>
<style name="GlobalTextViewStyle" parent="android:Widget.TextView">
<item name="android:textColor">#FF000</item>
<item name="android:textStyle">bold</item>
</style>
</resources>

<style name="normal_text_white" parent="#android:style/TextAppearance.Medium">
<item name="android:textColor">#color/white_color</item>
<item name="android:textSize">#dimen/small_text_size</item>
<item name="android:textColorHint">#color/hint_color</item>
</style>

We can try this as well for AppCompat widget.
<style name="TitleStyle" parent="TextAppearance.AppCompat">
<item name="android:gravity">center_horizontal</item>
<item name="android:textColor">#android:color/black</item>
<item name="android:textSize">26sp</item>
</style>

PreferenceFragment theme has big text? [duplicate]

I'm using a PreferenceFragmentCompat, but I don't think it is styled correctly.
Preferences' title seems way to big, PreferenceCategory text is unreadable, the whole think seems off.
This is what I have in theme.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
...
<item name="preferenceTheme">#style/PreferenceThemeOverlay</item>
</style>
<style name="PreferenceThemeOverlay">
<item name="preferenceScreenStyle">#style/Preference.PreferenceScreen</item>
<item name="preferenceFragmentStyle">#style/PreferenceFragment</item>
<item name="preferenceCategoryStyle">#style/Preference.Category</item>
<item name="preferenceStyle">#style/Preference</item>
<item name="preferenceInformationStyle">#style/Preference.Information</item>
<item name="checkBoxPreferenceStyle">#style/Preference.CheckBoxPreference</item>
<item name="switchPreferenceCompatStyle">#style/Preference.SwitchPreferenceCompat</item>
<item name="dialogPreferenceStyle">#style/Preference.DialogPreference</item>
<item name="editTextPreferenceStyle">#style/Preference.DialogPreference.EditTextPreference
</item>
<item name="preferenceFragmentListStyle">#style/PreferenceFragmentList</item>
</style>

Following this.
Change
<item name="preferenceTheme">#style/PreferenceThemeOverlay</item>
to
<item name="preferenceTheme">#style/PreferenceThemeOverlay.v14.Material</item>
Then, change in build.gradle dependencies
com.android.support:preference-v7
to
com.android.support:preference-v14

Change generated action bar theme from Android Asset Studio

I have used Android Asset Studio to generate action bar style, however i woul like to do some changes, which I was unable to do in Studio, so I edited generated theme but lot of things was just ignored, and I just can't figure out how things work.
There is example:
`
<style name="Theme.Myactionbar" parent="#style/Theme.AppCompat.Light">
<item name="actionBarItemBackground">#drawable/selectable_background_myactionbar</item>
<item name="popupMenuStyle">#style/PopupMenu.Myactionbar</item>
<item name="dropDownListViewStyle">#style/DropDownListView.Myactionbar</item>
<item name="actionBarTabStyle">#style/ActionBarTabStyle.Myactionbar</item>
<item name="actionDropDownStyle">#style/DropDownNav.Myactionbar</item>
<item name="actionBarStyle">#style/ActionBar.Solid.Myactionbar</item>
<item name="actionModeBackground">#drawable/cab_background_top_myactionbar</item>
<item name="actionModeSplitBackground">#drawable/cab_background_bottom_myactionbar</item>
<item name="actionModeCloseButtonStyle">#style/ActionButton.CloseMode.Myactionbar</item>
</style>
<style name="ActionBar.Solid.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid">
<item name="background">#drawable/ab_solid_myactionbar</item> //THIS IS GREEN
<item name="backgroundStacked">#drawable/ab_solid_myactionbar</item>//THIS IS GREEN
<item name="backgroundSplit">#drawable/ab_bottom_solid_myactionbar</item>//THIS IS GREEN
<item name="progressBarStyle">#style/ProgressBar.Myactionbar</item>
</style>
<style name="ActionBar.Transparent.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionBar">
<item name="background">#drawable/ab_transparent_myactionbar</item>
<item name="progressBarStyle">#style/ProgressBar.Myactionbar</item>
</style>
<style name="PopupMenu.Myactionbar" parent="#style/Widget.AppCompat.Light.PopupMenu">
<item name="android:popupBackground">#drawable/menu_dropdown_panel_example </item>
</style>
<style name="DropDownListView.Myactionbar" parent="#style/Widget.AppCompat.Light.ListView.DropDown">
<item name="android:listSelector">#drawable/selectable_background_myactionbar</item>
</style>
<style name="ActionBarTabStyle.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionBar.TabView">
<item name="android:background">#drawable/tab_indicator_ab_myactionbar</item>
</style>
<style name="DropDownNav.Myactionbar" parent="#style/Widget.AppCompat.Light.Spinner.DropDown.ActionBar">
<item name="android:background">#drawable/spinner_background_ab_myactionbar</item>
<item name="android:popupBackground">#drawable/menu_dropdown_panel_myactionbar</item>
<item name="android:dropDownSelector">#drawable/selectable_background_myactionbar</item>
</style>
<style name="ProgressBar.Myactionbar" parent="#style/Widget.AppCompat.ProgressBar.Horizontal">
<item name="android:progressDrawable">#drawable/progress_horizontal_myactionbar</item>
</style>
<style name="ActionButton.CloseMode.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionButton.CloseMode">
<item name="android:background">#drawable/btn_cab_done_myactionbar</item>
</style>
<!-- this style is only referenced in a Light.DarkActionBar based theme -->
<style name="Theme.Myactionbar.Widget" parent="#style/Theme.AppCompat">
<item name="popupMenuStyle">#style/PopupMenu.Myactionbar</item>
<item name="dropDownListViewStyle">#style/DropDownListView.Myactionbar</item>
</style>
Everything was like in generator, but then i tried the simplest change, that is the color, so I edited style name=ActionBar.Solid.Myactionbar and put there som other drawables from other generated style.
It looked like this :
<style name="Theme.Myactionbar" parent="#style/Theme.AppCompat.Light">
<item name="actionBarItemBackground">#drawable/selectable_background_myactionbar</item>
<item name="popupMenuStyle">#style/PopupMenu.Myactionbar</item>
<item name="dropDownListViewStyle">#style/DropDownListView.Myactionbar</item>
<item name="actionBarTabStyle">#style/ActionBarTabStyle.Myactionbar</item>
<item name="actionDropDownStyle">#style/DropDownNav.Myactionbar</item>
<item name="actionBarStyle">#style/ActionBar.Solid.Myactionbar</item>
<item name="actionModeBackground">#drawable/cab_background_top_myactionbar</item>
<item name="actionModeSplitBackground">#drawable/cab_background_bottom_myactionbar</item>
<item name="actionModeCloseButtonStyle">#style/ActionButton.CloseMode.Myactionbar</item>
</style>
<style name="ActionBar.Solid.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid">
<item name="background">#drawable/ab_solid_example</item>
<item name="backgroundStacked">#drawable/ab_stacked_solid_example</item>
<item name="backgroundSplit">#drawable/ab_bottom_solid_myactionbar</item>
<item name="progressBarStyle">#style/ProgressBar.Myactionbar</item>
</style>
but nothing happend, and changed drawables supposed to be gray. I was wandering if anybody did this before and why this isnt working? Thank you

Ok I figured it out, there is values-v14 folder for styles for api level 14 and above, so you have to change these values too.
