如何在 Android 中以编程方式设置谷歌字体

App is crash Caused by:android.content.res.Resources$NotFoundException: Font resource ID#0x7f090002 could not be retrieved.

 val typeface = ResourcesCompat.getFont(applicationContext, R.font.halant)
 appVersionName.typeface = typeface

<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:app="http://schemas.android.com/apk/res-auto"
        app:fontProviderAuthority="com.google.android.gms.fonts"
        app:fontProviderPackage="com.google.android.gms"
        app:fontProviderQuery="Halant"
        app:fontProviderCerts="@array/com_google_android_gms_fonts_certs">
</font-family>

尽管以上两个答案都是正确的，但我将逐步详细介绍“可下载字体”，以便其他人理解。

Note: A device must have Google Play services version 11 or higher touse the Google Fonts provider.

在 版面编辑 ，选择一个TextView，然后在下房产 , 选择 fontFamily > 更多字体 .

选择想要的字体并确保您选择创建可下载字体(在您的字体文件夹中创建 xml 文件)并单击 好的 .

Android Studio automatically generates the relevant XML files that areneeded to render the font correctly in your app.

现在，您可以像这样直接将其添加到 TextView 中:

android:fontFamily="@font/halant_light"
     

或者像这样以编程方式使用可下载字体:

val request = FontRequest(
        "com.google.android.gms.fonts",
        "com.google.android.gms",
        "Halant", //your font
        R.array.com_google_android_gms_fonts_certs
    )
val callback = object : FontsContract.FontRequestCallback() {

    override fun onTypefaceRetrieved(typeface: Typeface) {
        // Your code to set the font goes here
    }

    override fun onTypefaceRequestFailed(reason: Int) {
        // Your code to deal with the failure goes here
        
    }
}
FontsContractCompat.requestFont(mContext, request, callback, mHandler)

如果您不想要上述编程方式，您可以使用我测试过的以下代码，并且运行良好:

val typeface = ResourcesCompat.getFont(applicationContext, R.font.halant_light)
fontText.typeface = typeface
