Question

Java

Some elements in android xml are loaded from dark theme resources, why?
on one screen there can be elements that are loaded from resources for both dark and light theme.
I declare the theme type when loading the application
if(mSettings.getBoolean("night_mode", false)==true)
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
else
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
