這裏是你可以做，使滑動順暢

1. 分別創建導航抽屜的佈局
2. 呼叫從片段

這裏的抽屜是爲了更好的理解

<?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:orientation="vertical" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<android.support.v4.widget.DrawerLayout 
    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:id="@+id/custom_drawer_layout"> 

    <fragment 
//this contains the layout of your fragment 
     android:id="@+id/drawer_fragement" 
     android:layout_width="260dp" 
     android:layout_height="match_parent" 
     android:layout_gravity="end" 
     android:name="adress to navigationdrawer class" 
     tools:layout="@layout/drawer_frag 
//this line tells which layout to inflate ontop of the fragment 
     /> 
</android.support.v4.widget.DrawerLayout> 

</LinearLayout> 

現在創建名稱爲drawer_frag一個loyout其中包含要顯示在你的抽屜

所有代碼的代碼

希望它有幫助
