好了，我已经经历几个StackOverflow的帖子了，但我仍然困惑，在这里该XML我的工具栏去。

Okay, I've been going through several StackOverflow posts now, but I'm still confused as to where this xml for my Toolbar goes.

<android.support.v7.widget.Toolbar
android:id="@+id/my_awesome_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:background="@styles/colorPrimary" />

这是否走在我的 /layout/activity_main.xml ？

推荐答案

工具栏的动作条的应用程序布局中使用的推广，有两种做法，现在回答你的问题：

Toolbar is a generalization of Action bars for use within app layouts, now to answer your question there are two practices:

不好的做法：

不好的做法是定义工具栏在每一个布局。

Bad practice is to define the Toolbar in every layouts.

标准做法：

标准的做法是定义布局和引用它在碱的活性。你只需要包括在任何布局您希望此工具栏布局（通过使用＆LT;包括＆GT; ）和扩展定义的基本活动在任何活动

Standard practice is to define a layout and reference it in a base activity. You just need to include this Toolbar layout in whichever layout you want (by using <include>) and extend the defined base activity in whichever activity.

此标准的做法将帮助您保持对工具栏单code碱基，节省您的时间从每一次定义工具栏。

This standard practice will help you keeping a single code base for Toolbar and save your time from defining Toolbar every time.

示例：谷歌I / O 2014年Android应用程序

toolbar_actionbar_with_headerbar.xml

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:iosched="http://schemas.android.com/apk/res-auto"
    style="@style/HeaderBar"
    iosched:theme="@style/ActionBarThemeOverlay"
    iosched:popupTheme="@style/ActionBarPopupThemeOverlay"
    android:id="@+id/toolbar_actionbar"
    iosched:titleTextAppearance="@style/ActionBar.TitleText"
    iosched:contentInsetStart="?actionBarInsetStart"
    android:layout_width="match_parent"
    android:layout_height="?actionBarSize" />

此工具栏布局中引用设置活动，如下所示：

This toolbar layout is referenced in settings activity as given below:

activity_settings.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".ui.SettingsActivity">

    <include layout="@layout/toolbar_actionbar_with_headerbar" />

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />
</LinearLayout>
