Question

我正在开发android studio中的应用程序。我正在尝试创建一个适合状态栏正下方的导航抽屉。出于某种原因，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_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical"
>


<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

    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_height="match_parent"
    android:layout_gravity="start"

    android:layout_width="match_parent"
    android:id="@+id/drawerLayout"
    >




<FrameLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    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_width="wrap_content"
    android:layout_height="match_parent"

    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！

Answer 1

这里需要工具栏：

<?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_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"//fit to top status bar
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_home_actvity"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        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_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true" //fit to top status bar
    tools:context=".activity.HomeActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            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>

您必须将工具栏包含在＆＃34; NavigationView＆＃34;

中

您的代码看起来像这样：

<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_width="match_parent"
    android:layout_height="match_parent"
    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_width="match_parent"
        android:layout_height="match_parent">

            <android.support.v7.widget.Toolbar
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"

                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_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:fitsSystemWindows="true">

    </android.support.design.widget.NavigationView>

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