I want to declare a custom view, BUT I also want the home logo with up icon to appear on the left with its default functionality. How can I achieve to use both?
Best way is to use XML styles:
<style name="Theme.Main" parent="android:Theme.Holo.Light">
<item name="android:actionBarStyle">#style/Widget.ActionBar</item>
</style>
<style name="Widget.ActionBar" parent="android:Widget.Holo.Light.ActionBar">
<item name="android:displayOptions">showHome|useLogo|showCustom</item>
<item name="android:customNavigationLayout">#layout/custom</item>
</style>
Then simply set this theme as either the application theme or activity them in AndroidManifest.xml

i am tuning my action bar, the problem is that when i set the background property in my child theme then action bar text will disappear:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/CustomActionBar</item>
<item name="actionBarStyle">#style/CustomActionBar</item>
</style>
<style name="CustomActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#android:color/holo_blue_dark</item>
<item name="background">#android:color/holo_blue_dark</item>
</style>
If i override the background then the remaining properties should come from the parent theme by my logic, this includes that the text is still visible.
In order to get the text back i need to write the following:
<item name="android:displayOptions">showHome|useLogo|showTitle</item>
Why do i need to write that? Why does setting the background remove the text from the parent theme? Thanks in advance for the clarifications.
The problem is that you are inheriting from an incorrect style. Instead of inheriting from Widget.Holo.Light.ActionBar make your actionBarStyle be a descendant of one of AppCompat styles, e.g. Widget.AppCompat.Light.ActionBar.Solid.
<style name="MyActionBarStyle" parent="Widget.AppCompat.Light.ActionBar.Solid">
<!-- override attributes here -->
</style>
I'm trying to change the Contextual Action Bar style using this snippet
<style name="AppTheme.Reader" parent="AppTheme">
<item name="android:actionModeStyle">#style/AppTheme.ActionMode</item>
<item name="actionModeStyle">#style/AppTheme.ActionMode</item>
</style>
<style name="AppTheme.ActionMode" parent="Widget.AppCompat.ActionMode">
<item name="background">#color/white</item>
<item name="titleTextStyle">#style/AppTheme.ActionMode.Title</item>
<item name="subtitleTextStyle">#style/TextAppearance.AppCompat.Widget.ActionMode.Subtitle</item>
</style>
And setting the theme in the right activity
android:theme="#style/AppTheme.Reader"
Then I've used a
TextView.setCustomSelectionActionModeCallback()
To intercept the selected text, but when it comes up the CAB it has the default style and seems that my custom hasn't been applied.
Where am I wrong?
Try to use the latest support lib (as of now: v23.4.0). Depends where your parent "AppTheme" inherits from, it may or may not work but if you try to inherit from the "AppCompat" theme the following should work and once you see the white background you can fill in the rest of the attributes:
<style name="AppTheme" parent="Theme.AppCompat">
<item name="actionModeStyle">#style/ActionModeTheme</item>
</style>
<style name="ActionModeTheme" parent="#style/Widget.AppCompat.ActionMode">
<item name="background">#color/white</item>
</style>
Of course assuming <color name="white">#fff</color> is defined in colors.xml
I'm trying to apply some styles to my app. I've created a custom theme for the ActionBar using this actionbarstylegenerator.
But I want to change also in my app, the stock blue Holo color, to a red one, at least on buttons.
So, I have the custom theme for the ActionBar (Compat), and for the other side, a custom theme to change the Holo color.
In my app, I have defined the custom theme for the Actionbar, and I want to set the custom Holo theme inside the Actionbar's theme, but I don't know how to call, or where can I find the item name's whose define the variable you want to modify.
This is, I need to set this:
<style name="ColorTheme" parent="android:Theme.Black">
<item name="android:checkboxStyle">#style/CheckBoxColorTheme</item>
<item name="android:buttonStyle">#style/ButtonColorTheme</item>
<item name="android:imageButtonStyle">#style/ImageButtonColorTheme</item>
</style>
Inside of this:
<style name="Theme.CustomActionBarTheme" parent="#style/Theme.AppCompat">
<item name="actionBarItemBackground">#drawable/ab_selectable_background</item>
<item name="popupMenuStyle">#style/PopupMenu</item>
<item name="dropDownListViewStyle">#style/DropDownListView</item>
<item name="actionBarTabStyle">#style/ActionBarTabStyle</item>
<item name="actionDropDownStyle">#style/DropDownNav</item>
<item name="actionBarStyle">#style/ActionBar.Transparent</item>
<item name="actionModeBackground">#drawable/cab_background_top_customactionbartheme</item>
<item name="actionModeSplitBackground">#drawable/cab_background_bottom_customactionbartheme</item>
<item name="actionModeCloseButtonStyle">#style/ActionButton.CloseMode</item>
</style>
Maybe you need to do this?
<style name="ColorTheme" parent="Theme.CustomActionBarTheme">
<item name="android:checkboxStyle">#style/CheckBoxColorTheme</item>
<item name="android:buttonStyle">#style/ButtonColorTheme</item>
<item name="android:imageButtonStyle">#style/ImageButtonColorTheme</item>
I have an Activity with a dark ActionBar. I need to remove its vertical dividers since my icons already have "built-in" dividers.
What I've tried goes below
Activity style:
<style name="sMain" parent="#android:style/Theme.Holo">
<item name="android:icon">#android:color/transparent</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
MyActionBar:
<style name="MyActionBar" parent="android:Widget.Holo.ActionBar">
<item name="android:actionBarDivider">#null</item>
</style>
This doesn't have any effect. Any ideas what I'm doing wrong?
You need to set the android:actionBarStyle attribute as part of the activity theme, not as part of the action bar style.
So I believe this should work:
<style name="sMain" parent="#android:style/Theme.Holo">
<item name="android:icon">#android:color/transparent</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="android:actionBarDivider">#null</item>
</style>
How to tell where attributes belong? I used to struggle with this too (usually solved by trial-and-error) until I discovered the use of the android.R.styleable class! Have a look here: https://developer.android.com/reference/android/R.styleable.html
If you do a search in the page for actionBarStyle you will see it shows up as Theme_actionBarStyle, meaning it is part of the Theme style (remember there is no technical difference between a theme and a style). If you do a search on ActionBar_ you will be able to iterate through all of the attributes that can be set as part of an ActionBar style.
In my Android app, I am using various custom themes in different activities, all of which work fine. All these themes use the same custom styles for buttons, edit controls etc.
My preferences use standard Preference activities, which I define in XML and style via the manifest.
However, when I have a preference that causes an alert dialog to get launched, for example a ListPreference, the dialog uses the standard buttons. It does seem to use my custom EditText style in the EditTextPreference... but not my background or text colour.
Anyone have any idea why this is happening ?
Some of the code:
Styles:
<style name="Theme.Prefs" parent="#android:style/Theme.Holo.Light">
<item name="android:windowBackground">#drawable/background</item>
<item name="android:buttonStyle">#style/CustomButtonStyle</item>
<item name="android:editTextStyle">#style/CustomEditTextStyle</item>
</style>
<style name="CustomButtonStyle" parent="#android:style/Widget.Holo.Button">
<item name="android:background">#drawable/custom_button</item>
<item name="android:textSize">#dimen/dialog_text_size_normal</item>
<item name="android:textColor">#color/dialog_control_colour</item>
</style>
<style name="CustomEditTextStyle" parent="#android:style/Widget.Holo.EditText">
<item name="android:background">#drawable/custom_textfield</item>
<item name="android:textColor">#color/dialog_control_colour</item>
<item name="android:textSize">#dimen/dialog_text_size_normal</item>
</style>
And in the manifest:
<activity
android:name="com.breadbun.prefs.MainPreferencesActivity"
android:theme="#style/Theme.Prefs"
android:screenOrientation="portrait">
</activity>
To customize the alertDialog you need to add the second row to your main theme, and then customize the DialogStyle the way you want it.
<style name="AppTheme" parent="android:Theme.Material">
<item name="android:alertDialogTheme">#style/DialogStyle</item>
</style>
<style name="DialogStyle" parent="android:Theme.Material.Dialog.Alert">
</style>
