Try focusing on the width of the navigation box, it should be between 240dp and 320dp . It will automatically configure with the correct field.
This is an example xml file that contains a fragment of a navigation box. Here, the width of the fragment is set in the folder as 280dp
<android.support.v4.widget.DrawerLayout 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/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <LinearLayout android:id="@+id/container_app_bar" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <include android:id="@+id/app_bar" layout="@layout/app_bar" /> <it.neokree.materialtabs.MaterialTabHost android:id="@+id/materialTabHost" android:layout_width="match_parent" android:layout_height="48dp" android:layout_below="@+id/app_bar" app:accentColor="@color/colorAccent" app:hasIcons="true" app:iconColor="@android:color/white" app:primaryColor="@color/colorPrimary" /> </LinearLayout> <android.support.v4.view.ViewPager android:id="@+id/viewPager" android:layout_width="match_parent" android:layout_height="0dp" android:layout_below="@+id/materialTabHost" android:layout_weight="1" /> </LinearLayout> <fragment android:id="@+id/fragment_navigation_drawer" android:name="com.example.fragments.FragmentDrawer" android:layout_width="@dimen/nav_drawer_width" android:layout_height="match_parent" android:layout_gravity="start" app:layout="@layout/fragment_navigation_drawer" tools:layout="@layout/fragment_navigation_drawer" /> </android.support.v4.widget.DrawerLayout>
Now this is an example that is a navigation box layout
<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" android:background="@android:color/white" tools:context="com.example.fragments.FragmentDrawer"> <android.support.v7.widget.RecyclerView android:id="@+id/drawerList" android:layout_width="match_parent" android:layout_height="wrap_content" /> </RelativeLayout>
It will be good practice if you set the width in the folder, rather than hardcoding.
