Setting a custom background color on Actionbar ShareActionProvider dropdownlist
I'm trying to set a custom background color to ShareActionProvider dropdownlist, I already changed holo actionbar color using this http://jgilfelt.github.io/android-actionbarstylegenerator/
As you can see the highlighted point at below image I could change the actionbar background color to orange but the ShareActionProvider dropdownlist background color is still gray. Does anyone have any idea how can I change it editing my theme in styles.xml?
Thank you very much for your time.
You will need to override the attribute listPopupWindowStyle .
From the looks of it, you're using Theme.Holo.Light . Add this to your base theme:
<style name="AppBaseTheme" parent="android:Theme.Holo.Light">
....
<item name="android:listPopupWindowStyle">@style/MyListPopupWindowStyle</item>
</style>
Now define MyListPopupWindowStyle like this:
<style name="MyListPopupWindowStyle" parent="@android:style/Widget.Holo.Light.ListPopupWindow">
<item name="android:popupBackground">@drawable/list_popup_background</item>
</style>
Next, create the drawable list_popup_background and you'll be done.
Output :
By the way, in the screenshot above, I have used a ColorDrawable as the background. That's why, the corners are not rounded, and there's no drop shadow. For that, you'll need to create a nine-patch drawable, similar to the one that android uses. Here's what it looks like:
My ColorDrawable was defined as:
<drawable name="list_popup_background">#33ffffff</drawable>
Some more info :
Android itself uses a state selector drawable for ListPopupWindow's background. The selector defines two states: state_above_anchor & state_below_anchor (reachable by default):
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_above_anchor="true" android:drawable="@android:drawable/menu_popup_panel_holo_light" />
<item android:drawable="@android:drawable/menu_dropdown_panel_holo_light" />
It might be a good idea for you to define something similar.
您可以通过colorBackground属性对其进行着色 。
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="actionBarTheme">@style/AppTheme.ActionBar</item>
</style>
<style name="AppTheme.ActionBar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:colorBackground">@color/red</item>
</style>
