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">.

How to change ListPreference button colors?

I use bellow style to change Dialog background color to dark, In preference page I use ListPreference and after apply this style, cancel button of ListPreference disappeared in dialog background.
<style name="AppThemeBase" parent="Theme.MaterialComponents.DayNight">
<item name="colorPrimary">#212D3B</item>
<item name="colorPrimaryDark">#172331</item>
<item name="colorAccent">#61A3D7</item>
<item name="android:textColorPrimary">#FFFFFF</item>
<item name="android:dialogTheme">#style/AppTheme.Dialog</item>
<item name="android:alertDialogTheme">#style/AppTheme.Dialog</item>
</style>
<style name="AppTheme.Dialog" parent="Theme.MaterialComponents.DayNight.Dialog">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:background">#212D3B</item>
<item name="colorPrimary">#61A3D7</item>
<item name="colorPrimaryDark">#8DB2D3</item>
<item name="colorAccent">#61A3D7</item>
</style>
Is there a way to change this button color?

Finally I found solution. I don't understand what is different between android:alertDialogTheme and alertDialogTheme (without android:) but preference screen used the alertDialogTheme to stylize dialogs.
By adding bellow item to AppThemeBase, my problem is resolved.
<item name="alertDialogTheme">#style/AppTheme.Dialog</item>
Final AppThemeBase :
<style name="AppThemeBase" parent="Theme.MaterialComponents.DayNight">
<item name="colorPrimary">#212D3B</item>
<item name="colorPrimaryDark">#172331</item>
<item name="colorAccent">#61A3D7</item>
<item name="android:textColorPrimary">#FFFFFF</item>
<item name="android:dialogTheme">#style/AppTheme.Dialog</item>
<item name="android:alertDialogTheme">#style/AppTheme.Dialog</item>
<item name="alertDialogTheme">#style/AppTheme.Dialog</item>
</style>
<style name="AppTheme.Dialog" parent="Theme.MaterialComponents.DayNight.Dialog">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:background">#212D3B</item>
<item name="colorPrimary">#61A3D7</item>
<item name="colorPrimaryDark">#8DB2D3</item>
<item name="colorAccent">#61A3D7</item>
</style>

How to style PreferenceFragmentCompat

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.

How to style DialogPreference with a custom theme?

In my application I was using Theme.Holo and Theme.Holo.Light without any issues. When Holo theme is used and I click on a DialogPreference/ListPreference, a popped dialog is also themed with Holo. Same for the Holo.Light. But when PreferencesActivity is styled with my custom theme, which is derived from Holo.Light, all dialogs are themed with Holo.Light. I think I am missing somthing in my theme. Could anyone help me? Thanks a lot!
Here is my theme code:

</style>
</resources>

I found this rather unformatted but otherwise nice answer.
The gist is that DialogPreferences are AlertDialogs created without the theme parameter, which means they apply which ever theme android:alertDialogTheme points to.
So I extended my theme like this to have the dialog themed:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#color/yellow_500</item>
<item name="colorPrimaryDark">#color/yellow_a700</item>
<item name="colorAccent">#color/purple_400</item>
<item name="android:alertDialogTheme">#style/DialogTheme</item>
</style>
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
<item name="colorPrimary">#color/yellow_500</item>
<item name="colorPrimaryDark">#color/yellow_a700</item>
<item name="colorAccent">#color/purple_400</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
</style>
</resources>
The colorPrimary, colorPrimaryDark and colorAccent in the AppTheme were the colours I wanted to have applied to the dialog as well.
Note that I needed the android:windowMinWidthMinor to prevent the dialog from collapsing horizontally.

I have clarifying questions, but can't ask them because of low rate. So: 1.Does your first style work correctly? 2.Are you sure, that theme #android:style/Theme.Holo.Light.Dialog has all items, you declared in TimePickerDialogFragmentGreen?For example:
<item name="android:tabWidgetStyle"> #style/TabWidgetGreenTheme</item>
3. Have you tried the idea proposed by Luksprog
And finally: I used something like that to create custom style for my EditTexts:
<style name="EditTextStyle" parent="#style/Indents">
<item name="android:textColor">#android:color/black</item>
<item name="android:background">#android:color/white</item>
<item name="android:textColorHint">#android:color/darker_gray</item>
<item name="android:textSize">14sp</item>
</style>
<style name="Indents" parent="#style/Margins">
<item name="android:paddingBottom">#dimen/activity_vertical_padding</item>
<item name="android:paddingTop">#dimen/activity_vertical_padding</item>
</style>
<style name="Margins">
<item name="android:layout_marginTop">#dimen/activity_vertical_margin </item>
<item name="android:layout_marginBottom">#dimen/activity_vertical_margin </item>
<item name="android:layout_marginLeft">#dimen/activity_horizontal_margin </item>
<item name="android:layout_marginRight">#dimen/activity_horizontal_margin </item>
</style>
