How to add some space under the last item in a Navigation Drawer?

Question

I have a Navigation Drawer that contains several items. I added a button on the bottom of the Navigation Drawer. The problem is that in small size screens the button covers the last item in the Drawer.

How can I add some space under the last item so the button won't cover anything?

Answer 1

I came up with an idea how to do it and it worked for me. What I needed to do is to add one more Item to the Drawer and then disable it.

The code is:

 <item
    android:title=""
    android:enabled="false" >
</item>

Very simple and easy!!!

May be you can try something like this

    <android.support.v4.widget.DrawerLayout 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: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="@dimen/nav_drawer_width"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:fitsSystemWindows="true">
            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content">
                <Button
                    android:id="@+id/remove_ads_button"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_alignParentBottom="true"
                    android:background="@color/red"
                    android:text="@string/remove_ads"
                    android:textColor="@color/white"
                    android:textSize="15sp" />

                        android:orientation="vertical"
                        android:paddingBottom="@dimen/padding_10dp">

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

                        <TextView

                            android:text="@string/action_contact_us"
                            android:textSize="@dimen/text_30sp"
                            android:drawableRight="@drawable/ic_contact_us"
                            android:drawablePadding="8dp"/>
                            <!--another menu items-->

                    </LinearLayout>
                </ScrollView>


            </RelativeLayout>
