Question

In my android app, i can change the theme, but to see the change I have to exit the app and open it again.

This is how I change the theme.

ThemeSetterActivity.setStyle(signup.this);

which happens on the create event.

But is there some code like this (below) that I can run, and will change the theme for all the activities.

foreach (activity act in app) {
    ThemeSetterActivity.setStyle(act.context);
}

thanks

As far as I know you can’t do it that way.

What I do is have each activity keep track of what theme it is currently using.
Then in each activities on resume just check if the current theme is still what it should be, if not restart the activity.

An easy way to get that application wide is to just have your base activity class implement that behavior, and then have all activities extend that.
