【中文标题】导航抽屉不适合状态栏下方（android studio）[重复]【英文标题】：Navigation Drawer does not fit underneath the status bar (android studio) [duplicate] 【发布时间】：2016-12-04 21:02:40 【问题描述】：我正在 android studio 中开发一个应用程序。我正在尝试创建一个适合状态栏正下方的导航抽屉。由于某种原因，导航栏显示在应用栏下方，而不是像这张图片中那样：
Navdrawer1
我希望它看起来像这样：
Navdrawer2
这是我的 xml 代码：
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_
android:layout_
android:fitsSystemWindows="true"
android:orientation="vertical"
>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_
android:layout_
android:background="#ff4000"
android:id="@+id/toolbar"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:title="Home"
/>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_
android:layout_gravity="start"
android:layout_
android:id="@+id/drawerLayout"
>
<FrameLayout
android:orientation="vertical"
android:layout_
android:layout_
android:id="@+id/containerView">
</FrameLayout>
<android.support.design.widget.NavigationView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_
android:layout_
android:fitsSystemWindows="true"
android:layout_gravity="start"
android:background="#FFFFFF"
app:headerLayout="@layout/navigation_drawer_header"
android:id="@+id/shitstuff"
app:itemTextColor="@color/black"
app:menu="@menu/drawermenu"
android:layout_marginTop="-24dp"
/>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
任何帮助都会很棒！谢谢！
【问题讨论】：
【参考方案1】：这里你需要工具栏：
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_
android:layout_
android:fitsSystemWindows="true"//fit to top status bar
tools:openDrawer="start">
<include
layout="@layout/app_bar_home_actvity"
android:layout_
android:layout_ />
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_
android:layout_
android:layout_gravity="start">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
app_bar_home_actvity.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_
android:layout_
android:fitsSystemWindows="true" //fit to top status bar
tools:context=".activity.HomeActivity">
<android.support.design.widget.AppBarLayout
android:layout_
android:layout_
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_
android:layout_
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_home_actvity" />
</android.support.design.widget.CoordinatorLayout>
【讨论】：
工具栏中的背景是多余的。纯色背景和高度由 AppBarLayout 提供。 抱歉，没有收到您的评论【参考方案2】：您必须在“NavigationView”中包含您的工具栏
您的代码将如下所示：
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_
android:layout_
android:fitsSystemWindows="true"
tools:openDrawer="start">
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_
android:layout_>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_
android:layout_
android:background="#ff4000"
android:id="@+id/toolbar"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:title="Home"
/>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_
android:layout_
android:layout_gravity="left"
android:fitsSystemWindows="true">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
【讨论】：
*在DrawerLayout内，工具栏高度应为?actionBarSize。
英文不太懂，但是工具栏等组件必须在“CoordinatorLayout”之内。如果有一个外部组件“DrawerLayout”，只需可视化即可。尝试将视图的所有组件放在“CoordinatorLayout”中，这应该可以解决您的问题。
我知道，但请修正答案中的第一句话。【参考方案3】：

在 mainactivity 中更改为你的编码
