1、相關(guān)配置有先后順序之分

class ToolBarBuilder {
        private Toolbar toolbar;

2呀狼、樣式設(shè)置

<style name="AppTheme" parent="AppTheme.Base">

    </style>

    <style name="AppTheme.Base" parent="Theme.AppCompat">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>

        <item name="colorPrimary">@color/bg_toolbar</item>
        <!--配置系統(tǒng)欄的顏色-->
        <item name="colorPrimaryDark">@color/bg_system_bar</item>
        <!--配置整個窗口的背景顏色-->
        <item name="android:windowBackground">@color/bg_window</item>
    </style>

<style name="ToolbarTheme" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
        <!-- android:textColorPrimary is the color of the title text in the Toolbar  -->
        <item name="android:textColorPrimary">@android:color/white</item>

        <!-- Applies to views in their normal state. -->
        <!--<item name="colorControlNormal">@color/controlNormal</item>-->

        <item name="selectableItemBackground">?android:selectableItemBackground</item>
        <item name="selectableItemBackgroundBorderless">?android:selectableItemBackground</item>
