Question

What code do I need to go back to previous activity

Answer 1

First, thing you need to keep in mind that, if you want to go back to a previous activity. Then don't call finish() method when goes to another activity using Intent.

After that you have two way to back from current activity to previous activity:

Simply call: finish() under button click listener, Or Override the following method to back using system back button:

@Override
public void onBackPressed() {
    super.onBackPressed();
}
