I am currently making an app (Android 1.6) that can change between two different themes.
I made a custom theme that takes the Android light theme as a parent!
The trouble is that when I switch to white theme my text is not drawn but if I select something I can see the text. Furthermore when I switch themes my titleText, previous and next are the same as in my dark theme.
Here is the code I use for the theme:
<style name="Theme.White" parent="android:Theme.Light">
<item name="android:colorBackground">#color/text_color_dark</item>
<item name="android:textColor">#color/text_color_dark</item>
<item name="textPrev">#style/text_prev</item>
<item name="textRegular">#style/text_regular</item>
<item name="textTitle">#style/text_title</item>
<item name="textNext">#style/text_next</item>
<item name="pageBack">#style/page_back</item>
<item name="whiteBack">#style/white_back</item>
<item name="android:textColorPrimaryInverse">#android:color/primary_text_light</item>
</style>
</resources>
This is my style:
<style name="text_prev">
<item name="android:textColor">#color/text_color</item>
</style>
<style name="text_next">
<item name="android:textColor">#color/default_text_color_2</item>
</style>
<style name="text_regular">
<item name="android:textColor">#color/text_color_dark</item>
</style>
<style name="text_title">
<item name="android:textColor">#color/text_color_dark</item>
</style>
<style name="page_back">
<item name="android:background">#drawable/white_background</item>
</style>
<style name="white_back">
<item name="android:background">#drawable/white_container</item>
<item name="android:padding">10sp</item>
</style>
I use two more resources that are in my res/drawable folder. Everything works fine in the standard theme, but as soon as I switch to my light theme my text disappears.
Is there something that I'm doing wrong?
From your code snippet above you're setting both background and text to the same color i.e. "color/text_color_dark", these should be different.
<item name="android:colorBackground">#color/text_color_dark</item>
<item name="android:textColor">#color/text_color_dark</item>

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.
I tried change color of my actionBar divider , but nothing work. I' using android support library v7 for support old devices and custom style, and i also change all action bar drawable, but nothing happend!
<resources>
<style name="MyTheme" parent="Theme.AppCompat">
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
<style name="MyActionBar" parent = "Widget.AppCompat.ActionBar">
<item name="background">#drawable/my_action_bar</item>
</style>
</resources>
And my ide show me strange error in layout , why did i get this error? it's not color value
java.lang.NumberFormatException: Color value '#drawable/abs__ab_transparent_dark_holo' must start with #
Solution: Need to add android namespace if use for api level >= 14 .May be it will be helpful to someone.
It is because the "divider" is an image. It's hardcoded in the Holo theme assets.
Look at platforms/android-19/data/res/drawable-xxhdpi/ab_transparent_dark_holo.9.png
The style is declared here for holo dark.
<style name="Widget.Holo.ActionBar" parent="Widget.ActionBar">
...
<item name="android:background">#android:drawable/ab_transparent_dark_holo</item>
...
</style>
It's a background. You will need to change the color in the image and replace the background of your bar.
It also needs different sizes for different resolutions.
Maybe you should set color directly, change your theme as
<item name="android:divider">#color/dividercolor</item>
Then you should add color dividercolor in you /value/color file,like
<item name="dividercolor"> #0099CC </item>
I hope this will be helpful to you
<style name="CustomTheme" parent="#android:style/Theme.Holo.Light">

In my Android App I have added components for the arabic version like this:
In the styles.xml I defined:
<style name="HeaderImage">
<item name="android:background">#193660</item>
<item name="android:src">#drawable/logo_white_trans_96x96_300dpi</item>
<item name="android:scaleType">fitStart</item>
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
</style>
<style name="HeaderTitle">
<item name="android:background">#193660</item>
<item name="android:layout_width">fill_parent</item>
<item name="android:layout_height">match_parent</item>
<item name="android:textColor">#ffffff</item>
<item name="android:textSize">25sp</item>
<item name="android:gravity">right|center_vertical</item>
<item name="android:paddingLeft">15dip</item>
</style>
When I launch the emulator (with arabic locale) the text alignment is correct but all the styles are set to default. No Image is displaying and it's just the standard gray bar.
The only difference in the values/styles.xml is the gravity "left". The other files have been copied.
Can anyone tell me what I'm doing wrong?
It appears that I copied too many styles over to the "ar" directory. When I removed all the styles except the one in my code sample it used the Holo Theme again.
I'm using HoloEverywhere and ActionbarSherlock to create my application. I've been successful in theming the listview i have in my main activity so that the color is grey instead of holo blue whenever pressed or focused. I would like to theme the preference options I have in a PreferenceActivity as well, but it only works for devices with pre-ICS. With devices running android 4.0+, whenever the option is pressed or focused, the color is still ICS blue.
Another question: I'm using a theme that's parent is Holo.Theme.Light.DarkActionBar. How would I make it so that it uses a light overflow popupmenu instead of the dark one? I've tried adding popupmenustyle to my styles, but I've had no luck
styles.xml:
<style name="Theme" parent="Holo.Theme.Light.DarkActionBar">
<item name="android:actionBarItemBackground">#drawable/selectable_background</item>
<item name="actionBarItemBackground">#drawable/selectable_background</item>
<item name="android:activatedBackgroundIndicator">#drawable/activated_background_holo_light</item>
<item name="activatedBackgroundIndicator">#drawable/activated_background_holo_light</item>
<item name="android:listChoiceBackgroundIndicator">#drawable/list_selector_holo_light</item>
<item name="android:actionBarStyle">#style/ActionBar</item>
<item name="actionBarStyle">#style/ActionBar</item>
</style>
<style name="ActionBar" parent="#style/Widget.Sherlock.Light.ActionBar.Solid.Inverse">
<item name="android:background">#666666</item>
<item name="android:icon">#drawable/icon</item>
<item name="background">#666666</item>
<item name="icon">#drawable/icon</item>
</style>
For me this works:
<item name="popupMenuStyle">#style/PopupMenu.Intellistats</item>
<item name="android:popupMenuStyle">#style/PopupMenu.Intellistats</item>
where:
<style name="PopupMenu.Intellistats" parent="#style/Holo.ListPopupWindow">
<item name="android:popupBackground">#color/holo_orange_dark</item>
</style>
I want to get rid of the white color during the short period when my app is launching but the content isn't displayed, yet.
My main activity is using a style (from the Manifest) that extends #style/Theme.Sherlock.Light.DarkActionBar with the background set to <item name="android:background">#android:color/transparent</item>. Nowhere in my layout do I use a white background color, yet it appears for a brief moment during app launch.
In the HierarchyViewer I exported the layers and checked back that there is really no white solid in the layout hierarchy.
What setting controls the background color before the layout is drawn? Thanks.
There's another background attribute in your theme - windowBackground, and you implicitly set it to white by inheriting your style from #style/Theme.Sherlock.Light.DarkActionBar (notice the .Light. part in the name).
You can either use dark version of theme or set it explicitly by including windowBackground in your style definition:
<item name="android:windowBackground">#color/your_color</item>
<style name="Theme.Transparent" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowIsTranslucent">true</item>
</style>
Or you can use drawable. I created a theme for my spash screen like as below :)
<style name="SceneTheme.Light.NoActionBar" parent="Theme.MaterialComponents.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="SceneTheme.Light.NoActionBar.Transparent.StatusBar" parent="SceneTheme.Light.NoActionBar">
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowBackground">#drawable/bg_splash</item>
</style>
