What's happened to Monospace in Android Lollip

问题:

I have a style to use "monospace" in my Android App:

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Base application theme. -->
    <style name="AppTheme"  parent="Theme.AppCompat.Light.DarkActionBar" >
        <!-- Customize your theme here. -->
        <item name="android:windowNoTitle">true</item>
        <item name="android:typeface">monospace</item>
        <item name="android:textColorPrimary">@android:color/white</item>
        <item name="android:itemTextAppearance">@style/MenuText</item>
   </style>

   <style name="M13Text">
        <item name="android:typeface">monospace</item>
        <item name="android:textColor">@android:color/white</item>
        <item name="android:textColorLink">@android:color/holo_red_light</item>
   </style>

   <style name="MenuText">
       <item name="android:typeface">monospace</item>
       <item name="android:textColor">@android:color/black</item>
   </style>
</resources>

All was fine until Lollipop arrived when it doesn't seem use the Monospace font anymore and I can see it change when I flip APIs from 19 to 21 in Android Studio.

I've googled and not found anything and I appreciate it is just a cosmetic issue but anyone got any ideas as to why?

回答1:

The Material text appearances specify the android:fontFamily attribute rather than android:typeface so that they can use sans-serif-light, sans-serif-medium, etc. This attribute takes precedence over typeface, so you will need to either override or clear the fontFamily value.

<style name="MenuText">
    <item name="android:fontFamily">monospace</item>
    ...
</style>
