I have been looking for my question on Google and inside the forum but I cannot an answer so far. I am using android studio to code an app in Java

The thing is : inside a class, I have overrided the OnClick() method because I have to implement a lot of views. 

**Now I want to call a function just before OnClick() is called. 
What I mean is, for instance, if the user taps on a button, before OnClick() is called I want one of my methods to be called.**

Does anyone know how to do this ?

Thank you in advance
