couldn't find more appropriate title problem following. have linearlayout contains linearlayout , fragment. want add toolbar when so, see toolbar , other screen white.

here layout:

<?xml version="1.0" encoding="utf-8"?> <linearlayout 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:orientation="horizontal"     tools:context="xeniasis.mymarket.mainactivity">      <include         android:id="@+id/toolbar"         layout="@layout/toolbar" />      <linearlayout         android:layout_width="match_parent"         android:layout_height="match_parent"         android:baselinealigned="false"         android:weightsum="4">          <linearlayout             android:id="@+id/categories_layout"             android:layout_width="0dp"             android:layout_height="match_parent"             android:layout_weight="1"             android:paddingright="20dp">              <expandablelistview                 android:id="@+id/categories_listview"                 android:layout_width="match_parent"                 android:layout_height="match_parent" />         </linearlayout>          <fragment             android:id="@+id/mainpane"             android:name="xeniasis.mymarket.products"             android:layout_width="0dp"             android:layout_height="match_parent"             android:layout_weight="3"             tools:layout="@layout/activity_main" />     </linearlayout> </linearlayout> 

toolbar:

<android.support.v7.widget.toolbar xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="?attr/actionbarsize"     android:elevation="4dp"     android:padding="5dp"     android:theme="@style/toolbartheme" /> 

and fragment layout:

<?xml version="1.0" encoding="utf-8"?> <linearlayout 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:orientation="vertical"     tools:context="xeniasis.mymarket.mainactivity">      <android.support.design.widget.coordinatorlayout xmlns:android="http://schemas.android.com/apk/res/android"         android:id="@+id/main_content"         android:layout_width="match_parent"         android:layout_height="match_parent">          <android.support.v4.widget.swiperefreshlayout xmlns:android="http://schemas.android.com/apk/res/android"             android:id="@+id/swiperefreshcontainer"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:paddingbottom="@dimen/activity_vertical_margin"             android:paddingleft="8dp"             android:paddingright="8dp"             android:paddingtop="@dimen/activity_vertical_margin">              <gridview                 android:id="@+id/productsgridview"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:layout_alignparentbottom="true"                 android:layout_alignparentleft="true"                 android:layout_alignparentright="true"                 android:layout_alignparenttop="true"                 android:numcolumns="3"></gridview>          </android.support.v4.widget.swiperefreshlayout>          <android.support.design.widget.floatingactionbutton             android:id="@+id/settings"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_gravity="bottom|start"             android:layout_margin="8dp"             android:clickable="true"             android:elevation="5dp"             android:src="@android:drawable/ic_menu_search" />     </android.support.design.widget.coordinatorlayout> </linearlayout> 

this happens when have fragment, cause had same xml static layout fragment now.

the problem used linearlayout with

android:orientation="horizontal" 

and since toolbar has match_parent width occupies screen. try use

android:orientation="vertical"  

in root layout
