<linearlayout         android:id="@+id/test"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:orientation="vertical"> </linearlayout> 

in 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:id="@+id/main_content"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:fitssystemwindows="true"     tools:context="com.comfylight.bulbtest.foobar">      <linearlayout                 android:id="@+id/test"                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 android:orientation="vertical">      <android.support.design.widget.appbarlayout         android:id="@+id/appbar"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:paddingtop="@dimen/appbar_padding_top"         android:theme="@style/apptheme.noactionbar.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:layout_scrollflags="scroll|enteralways"             app:popuptheme="@style/apptheme.noactionbar.popupoverlay">          </android.support.v7.widget.toolbar>          <android.support.design.widget.tablayout             android:id="@+id/tabs"             android:layout_width="match_parent"             android:layout_height="wrap_content" />      </android.support.design.widget.appbarlayout>      <android.support.v4.view.viewpager         android:id="@+id/container"         android:layout_width="match_parent"         android:layout_height="match_parent"         app:layout_behavior="@string/appbar_scrolling_view_behavior" />      <android.support.design.widget.floatingactionbutton         android:id="@+id/fab"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="end|bottom"         android:layout_margin="@dimen/fab_margin"         android:src="@android:drawable/ic_dialog_email" />      </linearlayout> </android.support.design.widget.coordinatorlayout>
