java - Web view in XML lying under main bar -

i building app has webview configured in xml (fragment_recent_news) driven file (recent news), while webview configured meet main bar in xml (see picture), webview goes further under main bar should, though not following relative layout guidelines. doing wrong?

fragment_recent_news(xml):

<relativelayout 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" tools:context="com.hardingsoftware.hrcfitness.recentnews">   <webview     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:id="@+id/webview"     android:layout_alignparentleft="true"     android:layout_alignparentstart="true"     android:layout_alignparentbottom="true"     android:layout_alignparentright="true"     android:layout_alignparentend="true" />   </relativelayout> 

recentnews:

please remove

android:theme="@style/apptheme.noactionbar" manifest file. should work.

edit:

i did not know using coordinatorlayout

add android:theme="@style/apptheme.noactionbar" , put

app:layout_behavior="@string/appbar_scrolling_view_behavior" following component below.

<relativelayout         android:id="@+id/fragment_container"          app:layout_behavior="@string/appbar_scrolling_view_behavior" 

component.
