我使用follow代码更改字体，但在某些Android设备中不支持FragmentActivity。谁能帮助我，而不是

public final class FontsOverride {

    public static void setDefaultFont(Context context,
            String staticTypefaceFieldName, String fontAssetName) {
        final Typeface regular = Typeface.createFromAsset(context.getAssets(),
                fontAssetName);
        replaceFont(staticTypefaceFieldName, regular);
    }

    protected static void replaceFont(String staticTypefaceFieldName,
            final Typeface newTypeface) {
        try {
            final Field staticField = Typeface.class
                    .getDeclaredField(staticTypefaceFieldName);
            staticField.setAccessible(true);
            staticField.set(null, newTypeface);
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        }
    }
}

然后您需要重载几个默认字体，例如：

FontsOverride.setDefaultFont(this, "DEFAULT", "MyFontAsset.ttf");
FontsOverride.setDefaultFont(this, "MONOSPACE", "MyFontAsset2.ttf");
FontsOverride.setDefaultFont(this, "SANS_SERIF", "MyFontAsset3.ttf");

当然，如果你使用相同的字体文件，你可以改进它只加载一次。

但是我倾向于覆盖一个，说“MONOSPACE”，然后设置一个样式来强制该字体字体应用程序：

<resources>
    <style name="AppBaseTheme" parent="android:Theme.Light">
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <item name="android:typeface">monospace</item>
    </style>
</resources>

Answer 1

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:textViewStyle">@style/monospaceTextViewStyle</item>
    <item name="android:buttonStyle">@style/monospaceButtonStyle</item>
</style>

<style name="monospaceTextViewStyle" parent="android:Widget.TextView">
    <item name="android:typeface">monospace</item>
</style>

<style name="monospaceButtonStyle" parent="android:Widget.Holo.Button">
    <item name="android:typeface">monospace</item>
</style>

注意：这适用于API版本＆gt;只有16 ..

我已获得其他解决方案，请参阅以下源代码

将您的字体文件复制到assets文件夹。资产 --fonts --FuturaLT.ttf --XXXX.ttf --FuturaLT.ttf
在您的应用类中添加源代码

公共类MyApp扩展了Application {

public MyApp() {
    super();
}

@Override
public void onCreate() {

    super.onCreate();

    // change App Font
    changeAppFont();

} 


private void changeAppFont(){

    setDefaultFont(this, "DEFAULT", "fonts/FuturaLT.ttf");
    setDefaultFont(this, "DEFAULT_BOLD", "fonts/FuturaLT-Bold.ttf");

    setDefaultFont(this, "MONOSPACE", "fonts/FuturaLT-Oblique.ttf");
    setDefaultFont(this, "SANS_SERIF", "fonts/FuturaLT.ttf");
    setDefaultFont(this, "SERIF", "fonts/FuturaLT.ttf");
}

public static void setDefaultFont(Context context,
        String staticTypefaceFieldName, String fontAssetName) {
    final Typeface regular = Typeface.createFromAsset(context.getAssets(),
            fontAssetName);
    replaceFont(staticTypefaceFieldName, regular);
}

protected static void replaceFont(String staticTypefaceFieldName,
        final Typeface newTypeface) {
    try {
        final Field staticField = Typeface.class
                .getDeclaredField(staticTypefaceFieldName);
        staticField.setAccessible(true);
        staticField.set(null, newTypeface);
    } catch (NoSuchFieldException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    }

}
