减少在导航抽屉里的一些元素的TEXTSIZE

Question

我NavigationDrawer看起来像这样：

我想减少的类别标签之间的空间，并降低其TEXTSIZE让他们看起来更像是一个清单，占用空间少。我怎样才能做到这一点？

activity_main.xml中

<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" 
android:fitsSystemWindows="true" 
tools:openDrawer="start"> 

<include 
    layout="@layout/app_bar_main" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"/> 

<android.support.design.widget.NavigationView 
    android:id="@+id/navigation_drawer_container" 
    android:layout_width="wrap_content" 
    android:layout_height="match_parent"

    <LinearLayout

    </LinearLayout> 


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

定制文字大小在style.xml

<style name="NavDrawerTextStyle" parent="Base.TextAppearance.AppCompat"> 
    <item name="android:textColor">@color/colorPrimaryDark</item> 
    <item name="android:textSize">16sp</item> 
    <item name="android:textStyle">bold</item> 
</style> 

在NavigationView ：

<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" 
android:fitsSystemWindows="true" 
tools:openDrawer="start"> 

<android.support.design.widget.NavigationView 
    ... 
    app:itemTextAppearance="@style/NavDrawerTextStyle" 
    />
