在有些需求里面需要修改默认的字体，可以直接在Application里面写如下代码
FontsOverride.setDefaultFont(this, "DEFAULT", "fonts/xxx.ttf");//修改系统字体
FontsOverride.setDefaultFont(this, "MONOSPACE", "fonts/yyy.ttf");
FontsOverride类如下
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();
}
}
}
