将android工具栏弹出菜单主题从黑暗变为光

Question

I am using the appcompat v22 toolbar widget

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:popupTheme="@style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>

I want a light themed popup menu ( white background with black text ) Problem is the popup menu is always turning out be dark themed (looks like it is picking the styles from ThemeOverlay.AppCompat.Dark.ActionBar and setting android:popupTheme="@style/ThemeOverlay.AppCompat. Light" is not making any difference.

The problem occurred when I moved from app:theme to android:theme ( that's what is recommended if we need to use appcompat v22 version

I tried overriding the style and setting many values within the style

<style name="ToolBarPopUpTheme" parent="ThemeOverlay.AppCompat.Light">
    <item name="android:colorBackground">#ffffff</item>
    <item name="android:textColor">#ffffff</item>
    <item name="android:textColorPrimary">#ffffff</item>
    <item name="android:colorForeground">#ffffff</item>
    <item name="colorControlNormal">#ffffff</item>
    <item name="android:windowBackground">#ffffff</item>
</style>

But in vain, any idea how to get a light themed Popup menu in the ActionBar ?

Thanks,

Answer 1

You want to go back to app:popupTheme.

If you look at the source code for Toolbar.java you'll see the following on line 263.

setPopupTheme(a.getResourceId(R.styleable.Toolbar_popupTheme, 0));

R in this case is android.support.v7.appcompat.R (check out line 32), so the Toolbar is using the app: namespace for its attributes and not the android: namespace.

Out of curiosity, where did you read that you should be using the android:theme attribute?

As far as i see you are using the wrong parent style.

Give this a try:

<style name="ToolBarPopUpTheme" parent="@style/ThemeOverlay.AppCompat.Light" />
