I have created a horizontal menu in the main Activity , where one of your items has a button that calls a Activity that contains a ConstraintLayout p>

But when I enter that Activity it occupies the whole screen hiding the menu.

This is the xml code

activity_main.xml

</android.support.constraint.ConstraintLayout>

How can I leave that activity below the menus so they can be seen?

Thanks.

This would be the activity_main.xml is a DrawerLayout, it contains the left side menu inside a NavigationView, inside it we will put an app_bar_main:

<?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"
        tools:openDrawer="start">

        <include
            layout="@layout/app_bar_main"
            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:fitsSystemWindows="true"
            app:headerLayout="@layout/nav_header_main"
            app:menu="@menu/activity_main_drawer" />

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

This would be the app_bar_main.xml and within this layout we include the apuntes.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"
    tools:context=".activities.EventoActivity">

    <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" >
                <HorizontalScrollView
                    android:id="@+id/horizontal_menu"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent">

                </HorizontalScrollView>
        </android.support.v7.widget.Toolbar>

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

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

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

In layout notes, the context must be MainActivity:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
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"
tools:context="com.SoCu.CirDocu.MainActivity">

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

You can play putting things inside the AppBarLayout and Toolbar, so that it stays the way you like it.

In the apuntes.xml you can change the ConstraintLayout for a NestedScrollView, in case to put the horizontal mobile something is cut, that is already as you see:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView 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:fillViewport="false"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.SoCu.CirDocu.MainActivity"
    tools:showIn="@layout/activity_main">

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