Reduzieren Sie die textsize einiger Elemente in der Navigationsleiste

Question

meine NavigationDrawer sieht wie folgt aus:

ich den Raum zwischen den Kategorien Etiketten reduzieren wollen und ihre textsize zu reduzieren, so dass sie eher wie eine Liste aussieht und weniger Platz einnehmen . Wie kann ich das machen?

activity_main.xml

<android.support.v4.widget.DrawerLayout

android:layout_width="match_parent" 
android:layout_height="match_parent"

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

Answer 1

Ihre Textgröße in Ihrem 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> 

in Ihrem NavigationView anpassen :

<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" 
    />
