android - Navigation Drawer Below Toolbar

Question

I am trying to get the navigation drawer to open below the toolbar.

<android.support.v4.widget.DrawerLayout
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:id="@+id/drawer_layout"
tools:context=".MainActivity">
<RelativeLayout
    android:layout_width = "match_parent"
    android:layout_height = "wrap_content">
    <include layout="@layout/toolbar"
        android:id="@+id/toolbar"/>
    <FrameLayout
        android:layout_below="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/background_color"/>
</RelativeLayout>
<ListView
    android:id="@+id/drawer"
    android:layout_width="260dp"
    android:layout_height="match_parent"
    android:layout_below="@+id/toolbar"
    android:layout_marginTop="56dp"
    android:layout_gravity="start">
</ListView>
</android.support.v4.widget.DrawerLayout>

How do I reformat the xml so that the navigation bar opens below the toolbar?

Answer 1

You should move DrawerLayout as top parent and move Toolbar out of DrawerLayout content container. In short this looks like:

RelativeLayout
 ----Toolbar
 ----DrawerLayout
     ---ContentView
     ---DrawerList

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/top_parent"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".MainActivity">

    <include
        android:id="@+id/toolbar"
        layout="@layout/toolbar" />

    <android.support.v4.widget.DrawerLayout
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/toolbar">

        <FrameLayout
            android:id="@+id/content_frame"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/background_color" />

        <ListView
            android:id="@+id/drawer"
            android:layout_width="260dp"
            android:layout_height="match_parent"
            android:layout_below="@+id/toolbar"
            android:layout_gravity="start"
            android:layout_marginTop="56dp" />

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

However, Material Design guidelines state that Navigation Drawer should be above the Toolbar.
