    <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.coordinatorlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@color/tab_bck"     xmlns:design="http://schemas.android.com/apk/res-auto">         <linearlayout             android:id="@+id/linearverticallayout"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:orientation="vertical"             android:background="@color/tab_bck" >              <android.support.v7.widget.toolbar                 xmlns:android="http://schemas.android.com/apk/res/android"                 xmlns:app="http://schemas.android.com/apk/res-auto"                 android:layout_width="match_parent"                 android:id="@+id/expensetoolbar"                 android:layout_height="?attr/actionbarsize"                 android:elevation="6dp"                 app:layout_collapsemode="pin"                 app:layout_scrollflags="scroll|enteralways"                 app:popuptheme="@style/apptheme"                 app:navigationicon="?attr/homeasupindicator"                 app:titletextcolor="@android:color/white"                 app:subtitletextcolor="@android:color/white"                 android:background="@color/colorprimary">             <imageview                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 /></android.support.v7.widget.toolbar>               <framelayout                 android:id="@+id/fragment"                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 android:name="it.polito.mad17.viral.sliceapp.fragment_of_money"                 />             <listview                 android:id="@+id/listview2"                 android:layout_width="match_parent"                 android:layout_weight="1"                 android:layout_height="0dp"                 android:background="@color/tab_bck"                 android:longclickable="true"                 />              <android.support.design.widget.bottomnavigationview                  android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:id="@+id/bottom_nav_bar"                 android:layout_gravity="bottom"                 design:menu="@menu/bottom_nav_bar_menu"                 design:itemicontint="#16a085"                 design:itemtextcolor="#16a085"/>          </linearlayout> </android.support.design.widget.coordinatorlayout>

put bottombar outside linear layout. this:

 <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.coordinatorlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@color/tab_bck"     xmlns:design="http://schemas.android.com/apk/res-auto">         <linearlayout             android:id="@+id/linearverticallayout"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:orientation="vertical"             android:background="@color/tab_bck" >              <android.support.v7.widget.toolbar                 xmlns:android="http://schemas.android.com/apk/res/android"                 xmlns:app="http://schemas.android.com/apk/res-auto"                 android:layout_width="match_parent"                 android:id="@+id/expensetoolbar"                 android:layout_height="?attr/actionbarsize"                 android:elevation="6dp"                 app:layout_collapsemode="pin"                 app:layout_scrollflags="scroll|enteralways"                 app:popuptheme="@style/apptheme"                 app:navigationicon="?attr/homeasupindicator"                 app:titletextcolor="@android:color/white"                 app:subtitletextcolor="@android:color/white"                 android:background="@color/colorprimary">             <imageview                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 /></android.support.v7.widget.toolbar>               <framelayout                 android:id="@+id/fragment"                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 android:name="it.polito.mad17.viral.sliceapp.fragment_of_money"                 />             <listview                 android:id="@+id/listview2"                 android:layout_width="match_parent"                 android:layout_weight="1"                 android:layout_height="0dp"                 android:background="@color/tab_bck"                 android:longclickable="true"                 /> </linearlayout>             <android.support.design.widget.bottomnavigationview                  android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:id="@+id/bottom_nav_bar"                 android:layout_gravity="bottom"                 design:menu="@menu/bottom_nav_bar_menu"                 design:itemicontint="#16a085"                 design:itemtextcolor="#16a085"/>   </android.support.design.widget.coordinatorlayout>

commonjs - How to write a typescript definition file for a node module that exports a function? -
