您需要在设计库中使用主题

Question

Sometimes after rebuilding my app I get fatal error

a IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library.

I have view-builder class and dynamically add views into the parent layout, it seems it works perfect if I use Activity context, but for some reasons I want to use Application context, so I have this method

LayoutInflater provideLayoutInflater(Context context) {
    context.setTheme(R.style.AppThemeDark);
    return (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

context.setTheme(R.style.AppThemeDark); it's hack and it seems it doesn't work as expected, but I'm not sure.

Please help me to solve this issue. Thanks for any help

如果主要活动是从AppCompatActivity扩展，则必须使用从AppCompat降序的主题。
