如何更改选项菜单点的颜色？

Question

我想将选项菜单的点颜色更改为白色.我试图为此添加图像但不起作用.这该怎么做？

menu xml:

 <menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.example.siddhi.timetablelayout.Main2Activity">

    <item android:id="@+id/action_settings" android:title="@string/action_settings"
        android:orderInCategory="100" app:showAsAction="never"
        android:icon="@drawable/ic_more_vert_white_48dp"/>
</menu>

谢谢.

Answer 1

把它放进你style.xml的AppTheme:

<!-- android:textColorSecondary is the color of the menu overflow icon (three vertical dots) -->
<item name="android:textColorSecondary">@color/white</item>

Answer 2

您可以使用以下样式声明更改用于它的图像.

<style name="MyCustomTheme" parent="style/Theme.Holo">
<item name="android:actionOverflowButtonStyle">@style/MyCustomTheme.OverFlow</item>

</style>

<style name="MyCustomTheme.OverFlow">
<item name="android:src">@drawable/my_overflow_image</item>

</style>
