在主题中使用 fontFamily 属性时，Toast 使用 appcompat v26 抛出 ArrayIndexOutOfBoundsException

Question

每当我显示 Toast 时，应用程序就会崩溃。

如果我使用旧版本的 AppCompat 库或从样式中删除 fontFamily，应用程序可以正常工作。

onCreate:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toast.makeText(this, "Test", Toast.LENGTH_SHORT).show(); //line 13
}

依赖关系：

compile 'com.android.support:appcompat-v7:26.1.0'

AppTheme:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:fontFamily">sans-serif-light</item>
</style>

堆栈跟踪：

是否有任何替代方案，以便我可以使用最新版本的 AppCompat 库在主题中使用 fontFamily 属性？

Answer 1

在主题中添加字体如下-

    <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
        <item name="android:textViewStyle">@style/TextViewStyle</item>
        <item name="android:buttonStyle">@style/ButtonStyle</item>
    </style>

    <style name="TextViewStyle" parent="android:Widget.TextView">
        <item name="android:fontFamily">sans-serif-light</item>
    </style>

    <style name="ButtonStyle" parent="Widget.AppCompat.Button">
        <item name="android:fontFamily">sans-serif-light</item>
    </style>

根据 Android 开发人员指南 fonts in xml

Adding fonts to style

Open the styles.xml, and set the fontFamily attribute to the font file you want to access.
<style name="customfontstyle" parent="@android:style/TextAppearance.Small">
    <item name="android:fontFamily">@font/lobster</item> 
</style>

在你的情况下你应该加上 @font/ 前缀

<item name="android:fontFamily">@font/sans-serif-light</item>
