一些toolbar的设置

惯例先贴代码

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>

        <!--<item name="android:actionMenuTextColor">@android:color/white</item>-->
        <!--<item name="actionOverflowMenuStyle">@style/PopupMenu</item>-->
    </style>

    <style name="toolbar_style" parent="ThemeOverlay.AppCompat.Dark.ActionBar" >
        <item name="android:homeAsUpIndicator">@android:drawable/ic_menu_help</item>
        <item name="android:actionMenuTextColor">#11eeff</item>
        <item name="android:actionOverflowButtonStyle">@style/OverflowButtonStyle</item>
    </style>

    <style name="OverflowButtonStyle" parent="@android:style/Widget.ActionButton.Overflow">
        <item name="android:src">@android:drawable/ic_lock_idle_low_battery</item>
    </style>
    <!--设置popupwindow样式-->
    <style name="PopupMenu" parent="@style/Widget.AppCompat.Light.PopupMenu.Overflow" >
        <item name="android:colorBackground">@color/colorPrimary</item>
        <item name="android:textColor">@android:color/white</item>
        <!--弹出菜单与标题栏的间距-->
        <item name="android:dropDownVerticalOffset">1dip</item>
        <item name="overlapAnchor">false</item>
    </style>
</resources>

在xml里给appbarLayout设置上android:theme="@style/toolbar_style"

自定义title并居中

<android.support.design.widget.AppBarLayout
    android:theme="@style/toolbar_style"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
       app:popupTheme="@style/PopupMenu"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <TextView
            android:text="title"
            android:layout_gravity="center"
            android:textColor="#fff"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>

让toolbar不显示title，supportActionBar.setDisplayShowTitleEnabled(false)

setSupportActionBar(toolbar)
       with(supportActionBar!!) {
           setDisplayHomeAsUpEnabled(true)
           setDisplayShowTitleEnabled(false) 
       }

设置R.id.home，也就是toolbar左边那个返回按钮的图标样式
supportActionBar.setDisplayHomeAsUpEnabled(true)先让图标显示出来
<item name="android:homeAsUpIndicator">@android:drawable/ic_menu_help</item>
上面代码中ThemeOverlay.AppCompat.Dark.ActionBar可以让按钮变白色
R.style.PopupMenu里的设置是控制多出来的的optionMenu弹出pop的样式，需要在xml中给toolbar设置上这个主题
设置optionMenu的字体颜色<item name="android:actionMenuTextColor">#11eeff</item>

6.设置右边那三个点的图标样式<item name="android:actionOverflowButtonStyle">@style/OverflowButtonStyle</item>
