步驟1：在res下建立font文件夾玖翅，把字體資源 tzlth.TTF 導入
步驟2：在font下建立font_style.xml
<font-family xmlns:app="http://schemas.android.com/apk/res-auto">
<font
app:font="@font/fzlth"
app:fontStyle="normal" />
</font-family>
步驟3：在values/styles.xml中添加 <item name="android:fontFamily">@font/font_style</item>
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<!--此處添加字體-->
<item name="android:fontFamily">@font/font_style</item>
</style>
</resources>
然后看textview效果是否生效
