Question

我目前正试图将我的导航抽屉放在我的工具栏上，但我无法弄清楚我的代码中出了什么问题。我已经在网上查了很多，但我仍然看不出我做错了什么。

这是我到目前为止所得到的：

 <?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    >


        <!-- This LinearLayout represents the contents of the screen  -->
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <!-- the Toolbar -->
            <android.support.v7.widget.Toolbar
                xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:app="http://schemas.android.com/apk/res-auto"
                android:id="@+id/toolbar"
                android:layout_height="wrap_content"
                android:layout_width="match_parent"
                android:fitsSystemWindows="true"
                android:minHeight="?attr/actionBarSize"
                app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
                android:background="?attr/colorPrimaryDark">
            </android.support.v7.widget.Toolbar>


                <!-- Rest of the Content View -->
                <RelativeLayout
                    xmlns:android="http://schemas.android.com/apk/res/android"
                    xmlns:tools="http://schemas.android.com/tools"
                    xmlns:app="http://schemas.android.com/apk/res-auto"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:paddingLeft="@dimen/activity_horizontal_margin"
                    android:paddingRight="@dimen/activity_horizontal_margin"
                    android:paddingTop="@dimen/activity_vertical_margin"
                    android:paddingBottom="@dimen/activity_vertical_margin"
                    app:layout_behavior="@string/appbar_scrolling_view_behavior"
                    tools:showIn="@layout/activity_main"
                    tools:context=".MainActivity">


                </RelativeLayout>



            <FrameLayout
                android:id="@+id/flContent"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />


        </LinearLayout>



        <LinearLayout
            android:layout_width="230dp"
            android:layout_height="match_parent"
            android:layout_gravity="left|start"
            android:fitsSystemWindows="true">

            <!-- drawer content -->

            <android.support.design.widget.NavigationView
                android:id="@+id/nvView"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:layout_gravity="start"
                android:background="@android:color/white"
                app:menu="@menu/drawer_menu"
                />

        </LinearLayout>

</android.support.v4.widget.DrawerLayout>

我已经用这个改变了我的style.xml，用我在其他帖子上看到的Actionbar替换了Actionbar ......

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="android:windowNoTitle">true</item>
        <!--We will be using the toolbar so no need to show ActionBar-->
        <item name="android:windowActionBar">false</item>
        <!-- colorPrimary is used for the default action bar background -->
        <item name="windowActionModeOverlay">true</item>

        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>
    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

</resources>

DrawerLayout与FrameLayout的工作方式相同，即最后声明的最高Z值。

不是100％但是：

发现它！我所做的一切实际上都很好，问题是当我创建我的项目时，Android Studio创建了activity_main.xml和content_main.xml ...我的所有代码都在content_main.xml中，其中包含在activity_main.xml中：

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

所以我删除了activity_main内容并从content_main.xml复制了我的所有代码然后删除了这个（content_main）和TADAAA ......我实际上不知道为什么它创建了这两个.xml文件而不仅仅是一个在第一个地方......神秘感仍然存在
