How to anchor the Footer at the bottom of the scre

问题:

I have Activity with the header, the menu and the footer. In vertical orientation of the screen the Footer is at the bottom of the ScrollView, but it should be fixed at the bottom of the screen. There must be a free space between the ScrollView and the Footer in vertical orientation.

How to make that the Footer be fixed at the bottom of the screen in vertical orientation?

You will have to expand one of your upper views to fill the remaining space by setting android:layout_weight="1" on it. This will push your last view down to the bottom.

check this link

below is your layout :

I have made some edits to your original layout. The footer will appear at 

the bottom now and not overlap with the content of the scrollview. It will appear like this:

<?xml version="1.0" encoding="utf-8"?>
<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:fitsSystemWindows="true">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <!--- Header-->
    <!--<include layout="@layout/header_layout" />-->

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/cardview_dark_background"
        android:orientation="vertical"
        android:id="@+id/ll_top">

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"                  
        android:src="@drawable/ic_action_hardware_keyboard_arrow_left" />
    </LinearLayout>
