Android datepicker dialog title pillarboxed - android

I'm trying to style the datepicker dialog. So far I managed to change the background and button color. But as you can see in the image below, the title is sort of 'pillar-boxed'.
My datepicker dialog with the dark boxes left and right of the title:
My xml code so far (values/styles.xml)
<style name="PickerDialogTheme_dark" parent="Theme.AppCompat.Dialog">
<item name="android:background">#color/colorBackground_bgreen</item>
<item name="android:buttonBarButtonStyle">#style/ButtonColor</item>
</style>
<style name="ButtonColor">
<item name="android:background">#color/colorBackground_bgreen</item>
</style>
In java it is just a regular datepicker dialog constructor with the theme set to PickerDialogTheme_dark and I'm trying to get this to work on pre Lollipop versions.
So hope you guys know how to get rid of this pillar-boxed title. If possible without using fragments and all in xml would be favourable :)

Fixed it finally after searching some more on the internet!
How my final xml code looks now:
<style name="PickerDialogTheme_dark" parent="Theme.AppCompat.Dialog">
<item name="android:gravity">center</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:alertDialogStyle">#style/DialogBackground_dark</item>
<item name="android:windowMinWidthMajor">#android:dimen/dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
</style>
<style name="DialogBackground_dark">
<item name="android:topDark">#color/colorAccent_bgreen</item>
<item name="android:centerDark">#color/colorAccent_bgreen</item>
<item name="android:bottomDark">#color/colorAccent_bgreen</item>
<item name="android:bottomMedium">#color/colorAccent_bgreen</item>
</style>
This is how it looks like now

How to style DatePicker Spinner in android

I am trying to customize the colors of the DatePicker using a spinner mode in React-Native on Android. I know this needs to be done in the styles.xml for Android and I have styled a and the calendar form of the DatePicker. I would also like to know how to remove the border and change the font color (example in picture (https://imgur.com/a/5kW2Etb)).
I am still fairly new to Android development so I am just a bit lost on how to target the specific things I need.
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:spinnerItemStyle">#style/SpinnerItem</item>
<item name="android:spinnerDropDownItemStyle">#style/SpinnerDropDownItem</item>
<item name="android:datePickerDialogTheme">#style/Dialog.Theme</item>
</style>
<style name="SpinnerItem" parent="Theme.AppCompat.Light.NoActionBar">>
<item name="android:textSize">18dp</item>
<item name="android:textStyle">bold</item>
</style>
<style name="SpinnerDropDownItem" parent="Theme.AppCompat.Light.NoActionBar">>
<item name="android:textColor">#ffffff</item>
<item name="android:textSize">18dp</item>
<item name="android:textStyle">bold</item>
<item name="android:gravity">center</item>
<item name="android:background">#E05B35</item>
</style>
<style name="Dialog.Theme" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">#FF0000</item>
<item name="android:textColorPrimary">#0000FF</item>
</style>
I want to make the left image look more like the right:
I am just looking for the correct Parent to be able to style my DatePicker spinner and possibly a resource which would show me all of the aspects I can target. My problem is lack of knowledge on what I need to target and how Android would label it. It would be awesome if someone knew about an online resource that updated in real time so I wouldn't need to recompile my app every time I make a change. I would appreciate a doc which would explain how to target each element. Thank you.

Theme.MaterialComponents does not change font of dialog title

I am using the material components theming for our app. Now we want a custom font, which I managed to apply almost everywhere with the theme below, which uses the various textAppearance... attributes defined by material components.
This works very well, and the theme is also applied to the AlertDialogs almost everywhere -- message text and buttons have the custom font, buttons have the correct accent colors etc.
Only the dialog title keeps the Roboto font, no matter what.
<!-- externalized font name for easier change -->
<string name="font_regular" translatable="false" tools:ignore="ReferenceType">#font/atma_regular</string>
<style name="Theme.App" parent="Theme.MaterialComponents.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:textColorPrimary">#color/textColorPrimary</item>
<item name="android:textColorSecondary">#color/textColorSecondary</item>
<item name="textAppearanceHeadline1">#style/TextAppearance.App.Button</item>
<item name="textAppearanceHeadline2">#style/TextAppearance.App.Button</item>
<item name="textAppearanceHeadline3">#style/TextAppearance.App.Button</item>
<item name="textAppearanceHeadline4">#style/TextAppearance.App.Button</item>
<item name="textAppearanceHeadline5">#style/TextAppearance.App.Button</item>
<item name="textAppearanceHeadline6">#style/TextAppearance.App.Button</item>
<item name="textAppearanceSubtitle1">#style/TextAppearance.App.Subtitle1</item>
<item name="textAppearanceSubtitle2">#style/TextAppearance.App.Subtitle2</item>
<item name="textAppearanceBody1">#style/TextAppearance.App.Body1</item>
<item name="textAppearanceBody2">#style/TextAppearance.App.Body2</item>
<item name="textAppearanceButton">#style/TextAppearance.App.Button</item>
<item name="android:textAppearanceLarge">#style/TextAppearance.App.Large</item>
<item name="android:textAppearanceMedium">#style/TextAppearance.App.Medium</item>
<item name="android:textAppearanceSmall">#style/TextAppearance.App.Small</item>
</style>
<style name="TextAppearance.App.Subtitle1" parent="TextAppearance.MaterialComponents.Subtitle1">
<item name="fontFamily">#string/font_regular</item>
<item name="android:fontFamily">#string/font_regular</item>
</style>
...
I tried to define an extra theme for the alert dialogs like so:
<style name="Theme.App" parent="Theme.MaterialComponents.Light.NoActionBar">
...
<item name="alertDialogTheme">#style/Theme.App.AlertDialog</item>
...
</style>
<style name="Theme.App.AlertDialog" parent="Theme.MaterialComponents.Light.Dialog.Alert">
<item name="android:windowTitleStyle">#style/TextAppearance.App.DialogWindowTitle</item>
</style>
<style name="TextAppearance.App.DialogWindowTitle" parent="ThemeOverlay.MaterialComponents.Dialog.Alert">
<item name="fontFamily">#string/font_regular</item>
<item name="android:fontFamily">#string/font_regular</item>
<item name="android:textSize">30sp</item>
</style>
But that resets the colors and fonts everywhere. The only thing that is applied, is the textSize.
It really shouldn't be so hard to achieve this, but I am out of ideas right now. I could apply the font programmatically, but that would be quite ugly.
As you mentioned the AlertDialog created by MaterialAlertDialogBuilder uses the style defined by the textAppearanceSubtitle1 attribute in your app theme.
Otherwise you can change the style used by the AlertDialog using something like:
new MaterialAlertDialogBuilder(MainActivity.this,
R.style.MyTitle_ThemeOverlay_MaterialComponents_MaterialAlertDialog)
.setTitle("Title")
.setMessage("Message......")
.setPositiveButton("ok", null)
.setNegativeButton("Cancel", null)
.show();
In your style you have to customize the materialAlertDialogTitleTextStyle attribute:
<style name="MyTitle_ThemeOverlay.MaterialComponents.MaterialAlertDialog" parent="#style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="materialAlertDialogTitleTextStyle">#style/MyTitle_MaterialAlertDialog.MaterialComponents.Title.Text</item>
</style>
<style name="MyTitle_MaterialAlertDialog.MaterialComponents.Title.Text" parent="#style/MaterialAlertDialog.MaterialComponents.Title.Text">
<item name="android:textAppearance">#style/MyTitle_TextAppearance.MaterialComponents.Subtitle1</item>
</style>
<style name="MyTitle_TextAppearance.MaterialComponents.Subtitle1" parent="TextAppearance.MaterialComponents.Subtitle1">
<item name="fontFamily">....</item>
<item name="android:fontFamily">....</item>
<item name="android:textStyle">.....</item>
</style>
Thanks to your question I realized that I was using the incorrect attribute to assign the title style (android:titleTextAppearance instead of android:windowTitleStyle).
It looks like your issue has been fixed in the meantime, as your exact code seems to work for me as of today.

Change color of frame around the dialog title in Android

I want to change the background of alert dialog title in theme.
I do following changes in theme:
<style name="NgTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:dialogTheme">#style/NgDialogTheme</item>
<item name="android:alertDialogTheme">#style/NgAlertDialogTheme</item>
</style>
<style name="NgDialogTheme" parent="#android:style/Theme.Holo.Light.Dialog">
<item name="android:background">#android:color/transparent</item>
<item name="android:windowTitleStyle">#style/NgWindowTitleStyle</item>
</style>
<style name="NgAlertDialogTheme" parent="#style/NgDialogTheme">
</style>
<style name="NgWindowTitleStyle" parent="android:TextAppearance.Holo.DialogWindowTitle">
<item name="android:background">#318d99</item>
<item name="android:textColor">#fff</item>
</style>
I expected that background of title becomes #318d99. But only background of text is #318d99:
How can I change white frame around the title to #318d99?
Also the frame around the dialog isn't transparent. How can I fix it?
There are some valuable posts about this already and very closely related to your question.
Google's post on customizing this is possibly worth looking at first:
https://sites.google.com/site/androidhowto/how-to-1/customize-alertdialog-theme
Take a look at this blog post:
http://blog.supenta.com/2014/07/02/how-to-style-alertdialogs-like-a-pro/
Specifically, go to Part 5: Styling the Background.
To summarize, they suggest that you will probably have to
Stop inheriting from Holo
Give your main theme an alertDialogStyle
Then create a style with the following attributes, which you can get a reference to here: http://developer.android.com/reference/android/R.styleable.html#AlertDialog
You'll want to create a new style that inherits from the default alertdialog theme (this is discussed in both posts I mentioned above):
<style name="CustomDialogTheme" parent="#android:style/Theme.Dialog">
<item name="android:bottomBright">#color/white</item>
<item name="android:bottomDark">#color/white</item>
<item name="android:bottomMedium">#color/white</item>
<item name="android:centerBright">#color/white</item>
<item name="android:centerDark">#color/white</item>
<item name="android:centerMedium">#color/white</item>
<item name="android:fullBright">#color/orange</item>
<item name="android:fullDark">#color/orange</item>
<item name="android:topBright">#color/blue</item>
<item name="android:topDark">#color/blue</item>
</style>

What style would I need for an AlertDialog to bold?

I have an AlertDialog with buttons which I'd like to set to bold. I find the default style to be very thin:
but when I set the style as such:
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="android:textColorPrimary">#color/gray_dark</item>
<item name="colorAccent">#color/blue</item>
<item name="android:buttonStyle">#style/buttonStyle</item>
</style>
<style name="buttonStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:textStyle">bold</item>
</style>
I find the result to be, erhm, much bolder than I'd like:
I was aiming for something like this:
The screenshot is from WhatsApp. Are they using a different font or is it something I can replicate just by styling my XML file?
Based on the answer here, it seems that the correct style for what I want to achieve is adding these lines to the button style:
<item name="android:fontFamily">sans-serif-medium</item>
<item name="android:textStyle">normal</item>
Now I have the wanted "not so bold" look!

Can't find source of TYPE_SYSTEM_ALERT

For a project I want to create my own window style. I mean something like this:
<style name="MyFloatingWindow">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:background">#android:color/transparent</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowNoTitle">true</item>
</style>
To get some ideas how I can implement my ideas I want to look into the style source of andriod but I can't find it. What is the original style of WindowManager.LayoutParams.TYPE_SYSTEM_ALERT?
Or is it possible to create a new layout style with TYPE_SYSTEM_ALERT as parent? What do I have to write as parent?
<style name="MyOverlay" parent="android:***">
</style>
The TYPE_SYSTEM_ALERT simply means that the windows are always on top of application windows. In multiuser systems shows only on the owning user's window. It has nothing to do with the any style of your window or how the window will look like.
There are a lot of pre-defined styles in styles.xml under frameworks\base\core\res\res\values. For example the AlertDialog.
<style name="AlertDialog">
<item name="fullDark">#android:drawable/popup_full_dark</item>
<item name="topDark">#android:drawable/popup_top_dark</item>
<item name="centerDark">#android:drawable/popup_center_dark</item>
<item name="bottomDark">#android:drawable/popup_bottom_dark</item>
<item name="fullBright">#android:drawable/popup_full_bright</item>
<item name="topBright">#android:drawable/popup_top_bright</item>
<item name="centerBright">#android:drawable/popup_center_bright</item>
<item name="bottomBright">#android:drawable/popup_bottom_bright</item>
<item name="bottomMedium">#android:drawable/popup_bottom_medium</item>
<item name="centerMedium">#android:drawable/popup_center_medium</item>
<item name="progressLayout">#android:layout/progress_dialog</item>
<item name="horizontalProgressLayout">#android:layout/alert_dialog_progress</item>
</style>
