1 Button 2 activity in android studio using java

Question

How do I open another activity with the same button I clicked earlier? For example, I click button A and goes to Activity 1 and I click home and click button A again and must go to Activity 2.

I tried putting id on button in xml and call different activity on its java.

Answer 1

Imagine if the button is from HomeActivity,let the launcher activity pass an ExtraKey to the HomeActivity and again another ExtraKey at the OnBackPressed of the Activity you are navigating to after clicking the button.Set the onClickListner according to the String passed by those activities.
