I'm having a hard time trying to style a ListPreference.
I've applied a main theme which declares a preferenceTheme and both of them link to a dialogTheme (and alertDialogTheme respectively). It works except that the text color of the items doesn't change - but the color of all other texts does. I cannot rely on a workaround because I'm using the v7 preferences and thus cannot override the dialog methods in a custom class.
For me it looks like the rows ignore the text color value, but maybe someone else has a solution for this. Otherwise this might be a bug?
Main style:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- [...] -->
<!-- Some color values -->
<item name="android:dialogTheme">#style/DialogTheme</item>
<item name="android:alertDialogTheme">#style/DialogTheme</item>
<item name="dialogTheme">#style/DialogTheme</item>
<item name="alertDialogTheme">#style/DialogTheme</item>
<item name="preferenceTheme">#style/PreferenceTheme</item>
</style>
PreferenceTheme:
<style name="PreferenceTheme" parent="PreferenceThemeOverlay.v14.Material">
<!-- [...] -->
<!-- Some color values -->
<item name="android:textColor">#color/preference_primary_color</item>
<item name="android:textColorPrimary">#color/preference_primary_color</item>
<item name="android:textColorSecondary">#color/preference_primary_color</item>
<item name="android:textColorHighlight">#color/preference_primary_color</item>
<item name="android:editTextColor">#color/preference_primary_color</item>
<item name="android:dialogTheme">#style/DialogTheme</item>
<item name="android:alertDialogTheme">#style/DialogTheme</item>
<item name="preferenceTheme">#style/PreferenceTheme</item>
</style>
DialogTheme:
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:textColor">#EEEEEE</item>
<item name="android:textColorPrimary">#EEEEEE</item>
<item name="android:textColorSecondary">#EEEEEE</item>
<item name="android:textColorHighlight">#EEEEEE</item>
<item name="android:textColorTertiary">#EEEEEE</item>
<item name="android:textColorAlertDialogListItem">#EEEEEE</item>
<item name="android:editTextColor">#EEEEEE</item>
<item name="color">#EEEEEE</item>
</style>
This is how it looks.The text should be #EEEEEE. I've snipped it but the text colors are applied in each of the given styles.
You did everything right, except one thing: do not use the android prefix when overriding textColorAlertDialogListItem because this is not the framework version of AlertDialog.
This statement is generally true for almost all attributes that belong to the support widgets / views. The reason is pretty straightforward: not all attributes are available on the older platforms. Such example is android:colorControlActivated which was introduced in API 21. The AppCompat lib declares its own colorControlActivated so it's available on older API levels, too. In this case the developer should not use the android prefix when defining the style in the theme as that would point to the platform version of the attribute instead of the AppCompat one.
TL;DR: Do not use the android prefix for support widgets unless you have to (i.e. you get compilation error).
P.S.: I have created a fix / extension to the support preferences-v7 lib's annoying things that you might want to check out.
Also for radio buttons color add <item name="colorAccent">#000000</item> to your style.
Be careful, it's not android:colorAccent but colorAccent

I'm trying to style a TimePickerDialog for sdk 21+ (Lollipop). So far I've figured out how to change the default colorscheme in XML:
<style name="TimePickerTheme" parent="#style/Theme.AppCompat.Light.Dialog">
<item name="colorPrimary">#ff2d6073</item> <!-- no effect -->
<item name="colorPrimaryDark">#ff2d6073</item> <!-- no effect -->
<item name="colorAccent">#ff2d6073</item>
<item name="android:textColor">#ffD0D102</item>
<item name="android:textColorPrimary">#ffD0D102</item>
</style>
This works but I'm looking for a guide or documentation for all the properties I can change.
AccentColor does the basic color scheme
TextColorPrimary does the text color
But what property, for example, do I need to change the big text in the 'header' of the dialog (where the current selected time is displayed)?
Is there some documentation that lists all the possible things you can change?
After digging through the AOSP theme and style xml files and a lot of googling I made some progress. I am now able to style most(!) things.
So this is a partial answer, not all the way there yet. But here's how far I got:
You can see that I'm now able to theme the header, the un(!)selected time part (minutes in this case), the circle, the numbers in that circle and the 'hand' (or selector). Oh, and the buttons are styled, too.
Let me explain how I got things working, first: the important thing is that you can't override things directly from you app's theme OR from a (alert)dialog theme/style. You have to go from one to the next, so to speak.
Example:
AndroidManifest.xml: Set custom theme for app and/or activity
<activity>
android:theme="#style/Theme.MyTheme"
</activity>
values-v21/styles.xml: (where your custom theme resides): set the timePickerDialogTheme
<style name="Theme.MyTheme" parent="#style/Theme.AppCompat.Light">
<item name="android:timePickerDialogTheme">#style/TimePickerDialogTheme</item>
</style>
Then below that, define the timePickerDialogTheme and set the timePickerStyle:
<style name="TimePickerDialogTheme" parent="#style/Theme.AppCompat.Light.Dialog">
<item name="colorAccent">#ff2d6073</item> <!-- colorAccent here seems to work just fine? -->
<item name="android:timePickerStyle">#style/TimePickerDialogStyle</item>
</style>
Now you can define most of the styling here..
<style name="TimePickerDialogStyle" parent="#android:style/Widget.Material.Light.TimePicker">
<item name="colorAccent">#ff2d6073</item> <!-- colorAccent here seems to work just fine? -->
<item name="android:timePickerMode">clock</item>
<item name="android:headerBackground">#ff2d6073</item>
<item name="android:headerTimeTextAppearance">#style/TextAppearance.TimePickerDialogStyle.TimeLabel</item> <!-- TimePicker Time *TextAppearance* -->
<item name="android:numbersTextColor">#ff000000</item>
<item name="android:numbersSelectorColor">#ff2d6073</item>
<item name="android:numbersBackgroundColor">#ffdddddd</item>
</style>
The important line in the above is:
<item name="android:headerTimeTextAppearance">#style/TextAppearance.TimePickerDialogStyle.TimeLabel</item>
Because if you want to style the text (well, time, actually) in the header you need to define the headerTimeTextAppearance:
<style name="TextAppearance.TimePickerDialogStyle.TimeLabel" parent="#android:style/TextAppearance.Material">
<item name="android:textSize">60sp</item> <!-- from -->
<item name="android:textColor">#ffD0D102</item>
</style>
Now, if you take a look at the Widget.Material.TimePicker in AOSP styles.xml (ctrl-f 'timepicker' until you find it) you'll notice a bunch of other properties that you should be able to modify:
headerTimeTextAppearance
headerAmPmTextAppearance
headerSelectedTextColor
headerBackground
numbersTextColor
numbersBackgroundColor
amPmTextColor
amPmBackgroundColor
amPmSelectedBackgroundColor
numbersSelectorColor
Most of these work (as long as you prepend 'android:' for each of them) BUT I could not get 'headerSelectedTextColor' to work. I got a compile error saying something like "could not match property bla bla". Also, if you look at my example above, I hardcoded the textSize for the 'headerTimeTextAppearance' property because the '#dimen/timepicker_ampm_label_size' value threw errors.
In short: most of the things are listed above and how to get them working. But not all is clear. So I'd still see that complete documentation/guide :)
Android TimePicker material style with custom colors below, you can see http://www.zoftino.com/android-timepicker-example for TimePicker usage and styles.
<style name="MyAppThemeFour" parent="Theme.AppCompat.Light">
<item name="android:timePickerDialogTheme">#style/MyTimePickerDialogStyle</item>
</style>
<style name="MyTimePickerDialogStyle" parent="#style/ThemeOverlay.AppCompat.Dialog.Alert">
<item name="showTitle">false</item>
<item name="colorControlActivated">#ffd600</item>
<item name="colorAccent">#b71c1c</item>
<item name="android:textColorPrimary">#43a047</item>
<item name="android:textColorSecondary">#f44336</item>
</style>
When using version 1.5.0 of the Material Design Library for Android, I've found that I can get most of the theming with using this particular style:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyTimePickerTheme" parent="ThemeOverlay.MaterialComponents.TimePicker">
<item name="android:textColor">#FF121212</item>
<item name="android:textColorPrimary">#FF121212</item>
<item name="android:textColorSecondary">#FFF9F9F9</item>
<item name="colorAccent">#FF121212</item>
<item name="colorControlNormal">#FF121212</item>
<item name="colorPrimary">#FF121212</item>
<item name="colorSurface">#FFF9F9F9</item>
</style>
</resources>
This will yield in a generic - non colored - Dialog which works for white theme. For dark theme, simply invert the colors.
I've also asked here to have dynamic theming supported for this component.
Example screenshot using the above style:
I need to change text size of action buttons in AppBar/Toolbar. It should be 14sp, but I'll use 20sp in this example, because it is more evident. I am using appcompat-v7 22.1.1
At first I tried to use theme attribute android:actionButtonStyle:
<style name="FirstAttemptTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionButtonStyle">#style/Custom.Widget.AppCompat.Light.ActionButton</item>
</style>
<style name="Custom.Widget.AppCompat.Light.ActionButton" parent="Widget.AppCompat.Light.ActionButton">
<item name="android:textSize">20sp</item>
</style>
Then I ran application on the Lollipop and the result was as needed:
But then I used an emulator with lower version and my theming had no effect:
I digged a little deeper and discovered that abc_action_menu_item_layout.xml is used for action menu items and it has a line android:textAppearance="?attr/actionMenuTextAppearance"
So I tried to modify this theme attribute (I also had to add textStyle:bold):
<style name="SecondAttemptTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionMenuTextAppearance">#style/Custom.TextAppearance.AppCompat.Widget.ActionBar.Menu</item>
</style>
<style name="Custom.TextAppearance.AppCompat.Widget.ActionBar.Menu" parent="TextAppearance.AppCompat.Widget.ActionBar.Menu">
<item name="android:textSize">20sp</item>
<item name="android:textStyle">bold</item>
</style>
As in the first time, the result was as needed on Lollipop and no effect on any version below.
So, the question is: how to properly change text size for action menu item?
PS: I created a simple project on github to demostrate my issue
It appears that actionButtonStyle and actionMenuTextAppearance should be used without android: namespace.
As it can be seen in values-v21/values.xml of support library, Lollipop uses attribute from system theme (note the android: prefix), that's why my attempts worked with it:
<style name="Base.V21.Theme.AppCompat.Light" parent="Base.V7.Theme.AppCompat.Light">
...
<item name="actionButtonStyle">?android:attr/actionButtonStyle</item>
...
</style>
I make ActionBar in app.I change ActionBar style.There are some questions.
I want to change the title in the ActionBar.
So I write the follow code.
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="android:actionBarStyle">#style/ActionBar</item>
<item name="actionBarStyle">#style/ActionBar</item>
<item name="actionOverflowButtonStyle">#style/overflowButton</item>
</style>
<!--ActionBar-->
<style name="ActionBar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="android:background">#color/bg</item>
<item name="background">#color/bg</item>
<item name="android:title">#string/test</item>
<item name="title">#string/test</item>
</style>
<style name="overflowButton">
<item name="android:src">#mipmap/ic_add_black_48dp</item>
<item name="android:showAsAction"></item>
</style>
</resources>
when I only write <item name="android:title">#string/test</item> ,it doesn't work,but write <item name="title">#string/test</item> it work.
I have try to solve in Android Developer,but fail.Please help me.
<item name="title">#string/test</item>
this tag works on supporting library, and
<item name="android:title">#string/test</item>
this one works on your android. For more detail please have a look on here
I hope you understand, If not please let me know.
Note: If you are using the Support Library APIs for the action bar, then you must use (or override) the Theme.AppCompat family of styles (rather than the Theme.Holo family, available in API level 11 and higher). In doing so, each style property that you declare must be declared twice: once using the platform's style properties (the android: properties) and once using the style properties included in the Support Library (the appcompat.R.attr properties—the context for these properties is actually your app).
I use the newest ActionBarSherlock extension of the support library in my application. I came across a weird appearance of the views and action bar itself when I ran an app on emulator 4.2 and device with android 4.2 Please take a look at the screenshots from the emulator. We can see that blue line appears in every line separator in the ListView and underline the home icon.
Also the little right arrow is underline and not scaled properly as well.
And to put that in perspective, it display well in emulator with android 2.2
The way I use the Theme is:
ManifestFile.xml:
android:theme="#style/AppThemeWithoutTitle"
and styles.xml:
<style name="AppThemeWithoutTitle" parent="Widget.Sherlock.ActionBar">
<item name="actionBarStyle">#style/MyActionBarWithoutTitle</item>
<item name="android:actionBarStyle">#style/MyActionBarWithoutTitle</item>
</style>
<style name="MyActionBarWithoutTitle" parent="Widget.Sherlock.ActionBar">
<item name="android:displayOptions">useLogo|showHome</item>
</style>
How can I solve this issue?
Widget.Sherlock.ActionBar isn't a theme, it's a style. The first clue is it starts with Widget. The convention for themes in Android is to start it with the word Theme or at least put the word Theme in the name of the style.
The style you overrode and tried to use as a Theme is the style assigned to actionBarStyle which is the very thing you are trying to override.
You need to have an actual theme as your parent, then, and only then can you override actionBarStyle and have it work.
<style name="MyAppTheme" parent="Theme.Sherlock.Light.DarkActionBar">
<item name="actionBarStyle">#style/MyActionBarTheme</item>
<item name="android:actionBarStyle">#style/MyActionBarTheme</item>
</style>
<style name="MyActionBarTheme" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse">
<item name="background">#drawable/bg_striped</item>
<item name="android:background">#drawable/bg_striped</item>
<item name="backgroundSplit">#drawable/bg_striped_split</item>
<item name="android:backgroundSplit">#drawable/bg_striped_split</item>
</style>
You can find all the available themes you can override here.
I want to overload how an android Button looks, except I want to overload only one attribute i.e. the android:background. I know I could write something like:
<style name="App_TextButtonStyle" parent="???">
<item name="android:background">#drawable/filled_roundededges_nostroke</item>
</style>
Where parent="???" specifies which style I inherit from. My question is which style should I inherit from do that I get everything from the android default style for buttons and just define a new background.
I have used style for buttons without specifying "parent" attribute
<style name="BigButtonStyle">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_gravity">center_horizontal</item>
<item name="android:background">#drawable/backbutton</item>
<item name="android:textColor">#FFFFFF</item>
<item name="android:textSize">8pt</item>
<item name="android:textStyle">bold</item>
<item name="android:layout_margin">10pt</item>
</style>
I think it could be enough for you to define your style without "parent".
This is mostly for future visitors, I found a solution to the problem:
<style name="App_TextButtonStyle" parent="#android:style/Widget.Button">
<item name="android:background">#drawable/filled_roundededges_nostroke</item>
</style>
#android:style/Widget.Button references the default style of the button in the currently selected theme. You could also use the holo widget button style #android:style/Widget.Holo.Button (available since api 11).
You might want to look in <android-sdk-install-folder>/platforms/android-XX/data/res/values for the files styles.xml and themes.xml to check out all styles android uses for a given platform version.
