I have an activity with recycler view adapter class, when button clicked in adapter class I want to refresh the main activity

I have an activity with RecyclerView.Adapter class. RecyclerView contains button. When click that button I want to change a value defined in main activity and display it in TextView that also defined in main activity , otherwise I want to refresh the activity.

I already tried some code like:

• Android, How to call onCreate() explicitly from other method?

• How to restart the onCreate function
