导航抽屉内的项目字体大小不变

问题描述 投票:0回答:1

我想增加activity_main_drawer.xml里面项目的字体大小,这是导航抽屉菜单中显示的项目。我已经尝试通过添加android更改内部标记:textSize =“22dp”我还在style.xml文件中创建了“样式”

<style name="DrawerTextStyle" >
     <item name="android:textColor">@color/colorPrimaryDark</item>
     <item name="android:textSize">40dp</item>
     <item name="android:textStyle">bold</item>
 </style>

然后我申请activity_main_drawer.xml。但它没有生效。

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:showIn="navigation_view"
    android:theme="@style/DrawerTextStyle">

    <group android:checkableBehavior="single">
        <item
            android:id="@+id/author_nietzsche"
            android:icon="@drawable/ic_person_black_48dp"
            android:title="Friedrich Nietzsche" />
        <item
            android:id="@+id/author_rand"
            android:icon="@drawable/ic_person_black_48dp"
            android:title="Ayn Rand" />
        <item
            android:id="@+id/author_kant"
            android:icon="@drawable/ic_person_black_48dp"
            android:title="Immanuel Kant" />
        <item
            android:id="@+id/author_aurelius"
            android:icon="@drawable/ic_person_black_48dp"
            android:title="Marcus Aurelius" />
        <item
            android:id="@+id/author_descartes"
            android:icon="@drawable/ic_person_black_48dp"
            android:title="Rene Descartes" />
        <item
            android:id="@+id/author_schopenhauer"
            android:icon="@drawable/ic_person_black_48dp"
            android:title="Arthur Schopenhauer" />
        <item
            android:id="@+id/author_confucius"
            android:icon="@drawable/ic_person_black_48dp"
            android:title="Confucius" />
        <item
            android:id="@+id/author_russell"
            android:icon="@drawable/ic_person_black_48dp"
            android:title="Bertrand Russell" />
        <item
            android:id="@+id/author_sartre"
            android:icon="@drawable/ic_person_black_48dp"
            android:title="Jean-Paul Sartre" />

    </group

</menu>

有些人建议在activity_main.xml中分配它。但这也不起作用..

<android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer">

    </android.support.design.widget.NavigationView >
android styles themes navigation-drawer

您必须应用此属性:

android:theme="@style/DrawerTextStyle"

NavigationView而不是菜单, 但首先将dp改为sp

<style name="DrawerTextStyle" >
     <item name="android:textColor">@color/colorPrimaryDark</item>
     <item name="android:textSize">40sp</item>
     <item name="android:textStyle">bold</item>
 </style>
