嚮導航添加邊距Drawr

Question

這從來沒有發生在我身上。基本上我有一個導航抽屜佈局，當我顯示一個片段時，它會在所有邊上留下大約10dp的空間，所以它基本上會縮小一點。

This is the result.

app_bar_main.xml：

<RelativeLayout 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:layout_width="match_parent" 
android:layout_height="match_parent" 
android:fitsSystemWindows="true" 
tools:context="com.app.r6s.MainActivity" 
android:background="#464646"> 

<android.support.design.widget.AppBarLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:theme="@style/AppTheme.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:popupTheme="@style/AppTheme.PopupOverlay" /> 

</android.support.design.widget.AppBarLayout> 

<include 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    layout="@layout/content_main" 
    android:layout_alignParentStart="true" 
    android:layout_marginTop="55dp" /> 

content_main.xml：

<RelativeLayout 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/show_fragments" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
app:layout_behavior="@string/appbar_scrolling_view_behavior" 
tools:context="com.app.r6s.MainActivity" 
tools:showIn="@layout/app_bar_main"> 

片段我正在努力顯示：

<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.support.design.widget.TabLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/tab_layout"> 

</android.support.design.widget.TabLayout> 

<view 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    class="android.support.v4.view.ViewPager" 
    android:id="@+id/viewpager" 
    android:layout_marginTop="48dp"/> 

而替換片段代碼：

MyFragment fragment = new MyFragment(); 
     FragmentManager fm = getSupportFragmentManager(); 
     fm.beginTransaction().replace(R.id.show_fragments, fragment).commit();

什麼關於你的content_main.xml的補白？
