在您的活动中:
@Override
protected void attachBaseContext(Context newBase) {
super.attachBaseContext(CalligraphyContextWrapper.wrap(SLocaleHelper.onAttach(newBase)));
}
在您的应用程序主类:
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(SLocaleHelper.onAttach(base, "sv"));
MultiDex.install(this);
}
