如何使大写的BottomNavigationView菜单？

Question

我想在UpperCase中制作BottomNavigationView菜单，如何在不使用第3方库的情况下做到这一点？

这是我的xml代码：

<android.support.design.widget.BottomNavigationView
        android:id="@+id/navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="@android:color/white"
        android:foreground="?attr/selectableItemBackground"
        app:itemIconTint="@color/bottom_nav_color"
        app:itemTextColor="@color/bottom_nav_color"
        app:menu="@menu/navigation" />

和navigation.xml如下：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/navigation_home"
        android:icon="@drawable/home_icon"
        android:title="@string/title_home"
        />

    <item
        android:id="@+id/navigation_deals"
        android:icon="@drawable/ic_deals"
        android:title="@string/deals" />

    <item
        android:id="@+id/navigation_myBookings"
        android:icon="@drawable/ic_my_bookings"
        android:title="@string/title_my_bookings" />

   <item
        android:id="@+id/navigation_more"
        android:icon="@drawable/ic_more"
        android:title="@string/title_more" />
</menu>

Answer 1

尝试一下

创建这样的样式 BottomNavigationViewStyle

<style name="BottomNavigationViewStyle">
    <item name="android:textAllCaps">true</item>
    <item name="android:textSize">15sp</item>
</style>

比这样使用

<android.support.design.widget.BottomNavigationView
    android:id="@+id/navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_gravity="bottom"
    android:background="@android:color/white"
    android:foreground="?attr/selectableItemBackground"
    app:menu="@menu/navigation"
    app:theme="@style/BottomNavigationViewStyle" />

将此主题应用于您的底部导航

<!-- Reveal with active button -->
<button id="btn1">Reveal Frame 1</button>
<button id="btn2">Reveal Frame 2</button>
<br>
<!-- Reveal with checked radio -->
<input type="radio" id="rd1" name="reveal">
<label for="rd1">Reveal Frame 1</label>
<input type="radio" id="rd2" name="reveal">
