here's code:

<?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"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical">      <android.support.design.widget.appbarlayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:theme="@style/themeoverlay.appcompat.dark.actionbar">          <android.support.v7.widget.toolbar             android:id="@+id/toolbar"             android:layout_width="match_parent"             android:layout_height="?attr/actionbarsize"             android:background="?attr/colorprimary"             app:layout_scrollflags="scroll|enteralways"             app:popuptheme="@style/themeoverlay.appcompat.light" />       </android.support.design.widget.appbarlayout>      <relativelayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         app:layout_behavior="@string/appbar_scrolling_view_behavior">          <textview             android:id="@+id/txt_title"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:background="@color/light_rose"             android:padding="20dp"             android:text="contact"             android:textcolor="@android:color/white"             android:textsize="30dp" />          <scrollview             android:layout_width="fill_parent"             android:layout_height="fill_parent"             android:layout_above="@+id/footer"             android:layout_below="@+id/txt_title"             android:background="#0000ff"             android:fillviewport="true">              <textview                 android:id="@+id/texthere"                 android:layout_width="160dp"                 android:layout_height="wrap_content"                 android:layout_gravity="center_horizontal"                 android:gravity="center_vertical|center_horizontal"                 android:text="test test test test test test test test test test         test test test test test test test test test test test test test         test test test test test test test test test test test test test"                 android:textsize="35sp"></textview>          </scrollview>          <relativelayout             android:id="@+id/footer"             android:layout_width="match_parent"             android:layout_height="100dp"             android:layout_alignparentbottom="true"             android:background="#ffff00">              <textview                 android:id="@+id/texthere2"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:layout_centerhorizontal="true"                 android:layout_centervertical="true"                 android:text="things in footer here"                 android:textsize="20sp" />          </relativelayout>     </relativelayout> </android.support.design.widget.coordinatorlayout>

can give me hint?

instead of fixing button on bottom of view use bottom navigation bar. it's more appealing , attractive. must have seen bottom tabs on whatsapp, facebook , linkedin etc apps. it's , it's pretty easy too.

just follow link https://github.com/roughike/bottombar

or if want can share working code you. luck.
