 Values下创建atts.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <declare-styleable name="CNToolbar">
        <attr name="showSearchView" format="boolean"/>
        <attr name="leftButtonIcon" format="reference"/>
        <attr name="rightButtonIcon" format="reference"/>
        <attr name="myTitle" format="string"/>
    </declare-styleable>

</resources>

 style.xml

<resources>

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/red</item>
        <item name="colorPrimaryDark">@color/green</item>
        <item name="colorAccent">@color/blue</item>
        <item name="android:textColorPrimary">@color/white</item>
        <item name="android:windowActionBar">false</item>
        <item name="android:windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>
