Answer 1

只需使用finish（）方法，它将返回到先前的活动。

Answer 2

Chirag answer is what I would do, but correct me if I am wrong...

Wouldn'it be better to add the flag FLAG_ACTIVITY_REORDER_TO_FRONT:

Intent i = new Intent(getBaseContext(), ActivityB.class);
i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); 
ActivityA.this.startActivity(i);

that's hat I currently use in my application and would be sure that's a good idea.

Kind regards
